Hi, I've got a real interesting bit of kit for you today. This is a Cadence C7000 a commercial battery analyzer for Channel Jobby. Look at this. Um, this is a serious bit of kit made in Canada.

Thank you very much Hi to all my Canadian viewers! So this is a commercial analyzer designed for not just our production batteries, but also like in-service batteries. Return batteries, Uh, things like that to actually not only analyze their uh, capacity in milliamp hours or what hours, however, uh, you want to do it, but also to uh, rejuvenate cells based on, uh, very, the various chemistries and stuff like that and do all sorts of analysis functions. And it's a real serious bit of kit with a real serious, uh, price tag. And it's got these really absolutely fascinating with universal adapters with these Pogo pins on it.

As you can see, it's four channels so you can test four batteries uh at once and this is an 80 watt uh version total. but I think you can do like up to 55 watts per channel or something like that. And of course it can discharge as well as charge. And you know it can do lots of uh, fancy, like uh, production and uh, automation type stuff.

Like if your batteries have got a serialization in them, it can all be programmed if they've got uh, you know, battery gauges in them. like you can calibrate and recalibrate. Uh, battery gauges built into batteries. They're also known as coulomb counters and other things you can, you know do all sorts of fancy stuff with this.

and uh, the amazing thing about Kdxa. they're probably the ducks guts on the market. They've got over 3 000. I think there's actually over 3200.

They claim 3200 different adapters that you can plug into the just this series. This is not their only set they got, you know, much bigger ones and fancier ones. And if you're a manufacturer, I'm sure you can approach them and you know say hey, we've got this custom battery in our product. Can you, uh, you know, design us adapter that fits inside here that simply fits Our battery fits our product and I'm sure they got you know, tons of other Uh configurations.

A company like this that specializes in battery analyzers pretty much. um, then you know that's their only business and these are real expensive bits of kit so it looks like it's got a Uh two line, probably 40 character Lcd there. Um, and it's got four channels as I said, um and it can all be automated uh, via a Pc and software and you can get graphs and you can do you know programming into this and then you know the operators on the line can just you know, press the buttons and do whatever you need to do it. So I don't know how much stuff you can do on the keypad here and how much stuff has to be done in like you know, Pc software, menu and stuff.

I'm sure we can do some basic stuff you can see the adapter here. I'll probably take it out and have a better look, but it supports all different types of chemistries. although curiously, this one says warning not for use with Lithium batteries on C7000bos. I don't know what the Bos stands for, but this series does support Lithium batteries, so I don't know why just having the universal pin adapter in here would be a uh problem.

But anyway, um yeah, you can just lift those out. Uh, like that it's just got a card edge interface. With the whole idea with these is that you don't use universal adapters. uh, like this unless you're testing like many different, you know, types of batteries all the time or something like that.

Or you've got something oddball that you know you don't have an adapter for. The whole idea is that you buy an adapter that plugs in that suits your specific, uh, battery like and on the back here it does have a some sort of you know module or something. I don't know what that does. Um, it made like automation or something like that.

some sort of production automation. Uh, you know, interface relay. I o interface? Something like that, perhaps I can imagine. Um, Rs 232? Uh, serial interface and uh, yep.

made in Canada. I don't want my Canadian viewers and it's built like a tank and it weighs a lot. None of that switching rubbish. This thing's only 115 volts only so I assume like there's a linear big ass linear transformer in this and want to be.

It's bloody heavy enough. So yeah, I really like the design of this universal adapter actually uses Dc barrel jacks like this and these just pull out like that so it's just like a little uh, two millimeter um pin interface and so you can replace the uh probe tips and then they just slot into there and just the Dc barrel jack just goes into the positive and negative down there. Um, yeah, well, why not? Dc Barrel Jack adapter? It's cheap. It's simple, they're relatively, uh, robust, but I love how they've um yeah, how this arm works like it's springy loaded like this.

because when you've got contact spring contacts like this, you do want them to come down with like a little bit of force so that you know your pins make contact so you don't have to hold them down with your hands. So I guess the whole idea this one is, I guess designed for like maybe like a vertical battery comes out here. It has like the contacts on the top and then you can like separate these to the distance you want. like that it's got a little um, spring on the bottom, but you can still move them a little bit.

but yeah, you press on that, slides back and forth and then they just latch over in place like that at set distances. It's very nice and then you can just put that on top of your battery. Um, that's really cool. I don't know if they make like different types of, uh, universal adapters.

I don't know. They've got like over 3 200 adapters, but that's incredible. Anyway, let's tear this down anyway. You know we say you're on the Ev blog.

Don't turn it on. Take it apart. Let's start out with this battery adapter. Um, I don't expect much in here.

Maybe it's got some protection or something like that because I think all the goodness is going to be inside the analyzer. I mean, the analyzer itself is going to support all different uh, you know, voltage and cell configurations and you know stuff like that series and parallel uh, arrangements and stuff. But so that's the six six-way contact on each side. So 12 way, 12 contacts.

Didn't expect much. There's a little tiny fine wire going over there. My guess is that is a temperature sensor. It's going to be a thermocouple.

but yeah, there's basically nothing in there. didn't really expect. It's just basically a mechanical uh interface. And it does have a four wire interface.

so it's not just uh, red and black. so they're obviously tapping the voltage back on that. so that's what. Uh, they're using the barrel jack for the extra uh pin there because the two pin barrel jack is not used for like shielding or anything like that.

It's used for feedback so they're feeding back. It's a four wire measurement. They'd be feeding it back right on the pin there so you're not getting any voltage drop along the cables. You absolutely need that for any professional, or you know, semi-professional battery analyzer, especially for any serious amount of current.

Uh, you get, you know, significant drop on your cable and that's going to ruin your day. And you know, if you're talking about, uh, you know, touchy chemistries like uh, Lithium Ion, for example. the voltages are really important so you can't have any drop on there. So what's on the back here? Is there anything on the board? Yep, Nothing.

Um, and then put some large diodes for some, uh, protection there. but they haven't fitted those so I I don't No, but wait, there's more. Ah, they do. Complete with cobwebs.

No, they do have something on there. By the way, you can see that the thermocouple wire just goes, uh, directly back sold into the board. Now that connection? Rubbish. What chippy is that? Ah, that makes sense.

Yeah, nothing to do with the charging at all. It's just a, um, the E-squared uh, prom. So it has the Id so that the software and the device knows that. Uh, you know this particular module's plugged in.

and yeah, with over 3 200 of them, Yeah, you want it to auto identify when it just plugs in and then it, it'll know that. Okay, that. was designed for this particular battery with this particular cell configuration and this particular chemistry, etc etc. And I'm sure they design your custom, uh, one of these because you know there's no way they're just gonna like off their own Accord design 3200 different interfaces.

I'm sure that comes about because every manufacturer of every little mobile, uh, product with a removable battery has come to them and said hey, you know we want an adapter for it so they add it to their inventory and presumably anyone could buy it and uh, presumably you could probably get an adapter that like plugs into both at the same time like it's wider. They do have some basic instructions for using the keypad um, interface on this thing. but yeah, as I said like a lot of this is just like all, uh, pre-programmed production, uh type stuff you don't like you basically. um, trust me, as someone who comes from a production test engineering environment, you never want the operators to have access.

You know, I wouldn't surprise me if it's got like a lockout code and stuff like that. so you know you can't have the operators like around with this because trust me, they will. So ventilation on this thing. Just a fan here.

There's a bit of ventilation on the bottom. Ah, that's probably I. I reckon there's a mat. Yeah, yeah, yeah, I can see some points for a mains.

Uh, a big um, mains transformer in there. so I reckon there's a big bulky maze transformer there. so that's just, uh, the vents for that. And they've just got the vents along the top here because you know it does a reasonable amount of power.

So this is 2005 vintage so I wouldn't expect any uh, like modern arm process or anything like that. and of course it, uh, would date back. There'd be a lot of history in this company and I'm not sure when they started, but I'm sure it was way before then. they would have, of course had their own, um, in-house um, you know, favorite, uh, processor and they probably stuck with it.

probably even. uh, today. So it wouldn't surprise me to find like a Motorola Joby in here. No, no, something's oh no.

There we go. Oh, we're in. Oh dusty. Oh this.

It definitely needs a good so yeah, I'm gonna go do that now. out in the stairwell where all, uh, best happen? Um, yeah, I'll get back to you, there's the Lcd and keypad assembly designed in Canada upside down so all the electrons are going to fall out. They're quite, uh, proud of the old, uh designed and made in Canada. Aren't they There you go? But um, that's a pretty large main board.

It extends, uh, the entire depth of this thing. And there's your firmware. Uh, I wish I don't think this is uh, updatable remotely. I think uh, yeah, you have to pop in a new down there.

but yeah. like I like how they've very deliberately put it down here so you don't have to take all the rest of this assembly out. which yeah, presumably. I don't know how the rest of it comes out, but you don't have to take that out.

Um, yeah to access and uh, swap the uh rom down here. So yeah, very nice. I love how they got a right that, uh, right angle latched um Idc ribbon and connector as well. I love how they've done their uh leads down here too.

No need for light pipes or anything fancy like that. just have a uh cut out in the board, just uh, solder your leads on like that. you can get uh, reversey middle ones and but anyway, they just poke through the decal on the front. The clear window there nice looks like yeah, I have to undo these.

so these would be, uh, would these be um, metal threaded studs in the Pcb. We'll find out and they just lift out of there and um, yeah, somebody dropped a pin. I was just about to admire the uh design here. how this would hinge out because there's um, two nut and bolts over there.

there are threaded into the chassis. It's not like you can undo them from the outside and um, yeah, no it doesn't because the connectors in the way I want. Why can you make the cut out a bit bigger and just swing that out? Ah well. It's the next best thing in that it lifts out like that and the screws can stay in place.

So that's okay. I guess I don't know. I just wanted something to swing out, please. So anyway, there we have it.

That's pretty sweet. One large board in there, and uh, even the transformer made in Canada? Um, Atc Frost. Are they still in business? Leave it in the comments down below all my Canadian viewers. I'm sure they'll know a bit of rust on there.

now. What I find interesting is that I I expected, like a total of four, um, like power channels and of course, like, uh, we've got four, uh, chokes here, Are they? Yeah, there are four common mode chokes, so that's four switching something or others, right? We've got some switching in there, like that little surface mount jobbies and stuff like that. But interestingly, we've got two heatsinks like this, so we'll have to find out what they are. I don't think they're anything serious, but look, we've got four.

We've got seven vertical power resistors like this, right next to the fan fan. They're so close to the fan, so I don't know what that does to the thermals of this thing. But anyway, okay, you want to get the heat out all right? Um, yep, let's put it right next to the fan. Uh geez.

yeah. they're a little bit tight for a space in this sort of thing in the end, but because they went for the whole single board. uh, construction. But yeah, I'm just I don't know how those seven are related to the four channels because I believe all four channels are identical specs and looking at all the other circuitry in there, it looks like all the sensing and everything else.

all the you know, switching and whatnot. um is is the same for each channel. So so these I think two power transistors. or there's a sneaky one on the bottom.

Let me get my head under there. Yeah, there's a sneaky device on the other side. Okay, we that makes more sense. All right.

So we've got four power transistors, two on each heatsink. They're all um, insulated with a sill pad and nice little clip that just presses down on there. Nice another screw. Rubbish.

Excellent. uh-huh I was just about to say um, these heatsinks aren't going to be the series pass transistors for the electronic load which I've done a video on by the way because if it was um, then you wouldn't have such large power resistors like this. um for measuring currents sense. So obviously it'd be these transistors here.

Which then where's my probe these transistors here which would then um being used as the electronic uh load for the uh, dissipation in the big resistor there. So yeah, that's what they're doing. But once again, y7, Yes, so that's only a Lm317 in there adjustable voltage regulator, so I assume the same on the other side and the other two as well. Um, yeah, because uh, these heatsinks are just like mounted completely wrong for the thermals of that fan.

So yeah, yeah, I don't particularly like the thermal arrangement here. Look, they've even got them staggered. So like when the air, like, you know the air comes through like this, then it's then going to go up like this and then out like that. When you've got to go, when you block it like that, that's a real problem.

You want to have them lined up, so it at least flows, you know, relatively unrestricted over the surface, not goes in here and goes bang. Oh, I've got to go here around here like this. Um, no, that's a bit of a fail. so I don't like that.

And of course, the heatsink orientation. You want fins in this direction going going like this. So, and you want the airflow over the fins, you don't just want to blast it right on the um on the surfaces like that because it just gets stuck. It's got nowhere to go.

So the thermal design of this, um, yeah, it gets a thumbs down. And we've found our culprit down there. Yep, Motorola. I called it Hc-11 Jobby.

What's that? Oh, that's version one. so that's I. I don't know, Was that some say, is that like a boot rom or something like that? Anyway, all fairly discreet. Uh.

stuff happening here, which uh, yeah, you'd typically find in something of this age. And then I've got a Cpld down there. Do we? Oh, two of them? Uh, it kind of looks Cpld something like that. But yeah.

anyway. and then we've got all the uh, stuff surrounding each socket and they're gonna be identical spot. The different spot. The difference between each channel? I don't think you can.

There's a relay in there. Genuine omrun, Jobby. No cheap rubbish in this. And yep, they're all going to be absolutely identical.

So okay, we've found our dac down here. Well, one of them. anyway. there's another one.

This is a uh, octuple dac. but it's only which means eight of them. But it's only a six bit dac. so that's interesting.

But up above it here here you go. We now have a another, um, a dual 8-bit dac. So why they've got two there, plus an octuple? So I'm guessing because that's only a jewel. And well, as we saw they the bays in this thing, these were.

So these bays were kind of sort of physically tied together. So I guess there's only one 8-bit dac per double bay. And then, um, this one here with um, eight channels. Uh, six bit Joby? I presume that would be setting, Uh, the voltage, uh, limit and also, uh, current limit as well for both of those, uh, for each Um channel.

So that's why they need eight of them. So yeah, I can't see any others in there, so that's it. From the Dac side of things. Now, we need to find the Adcs Now this uh, linfinity part here.

next to um, each channel. there's four of those that's actually a uh, Pwm uh controller. So that would be for the Um switching, uh, charge and or load and on the switching part of these. So there's four of these channels that's a high side, uh, mosfet switching mosfet three actually three per channel, three other surface mount ones with, you know, a little bit of Pcb heatsink there.

I don't see any via stitching or anything. um, serious like that. so they're obviously not dissipating a huge amount. But uh, yeah.

but that's all pretty. uh, discrete stuff. But if the Pwm controller is like all the way over here, I kind of don't get that Like, you know why it's not over here. Next to the switching stuff? I don't know.

And check it out next to the deck here. I totally missed it. The Pick 16 F-84 classic. Why? they've just whacked a little micro in there.

Um, right near some of the Hcr 574 bus stuff for the Hc-11 micro up the top. That's just that just seems out of place. I don't. I don't get what's going on there anyway.

Um, we got some memory over here, but uh yeah, Why? you'd need a pick? So yeah, I don't get that. Um, why it? like is it a separate micro that controls the Dax? Maybe they decided that they want, you know, just dedicated uh, loop microcontroller loop functionality of the Dax? perhaps? Meh. Anyway, I see some off amps down in there. There's a current shunt resistor there that would be, uh, actual, uh, battery shunt resistor? Um, but I'm not seeing any Adc per channel yet.

There's got to be an Adc in here. Somewhere found like a bunch of Dax, but no Adc. Well, for the life of me I cannot find an Adc on here. If I do later, I'll put it in the edit, but I cannot find one.

So I reckon what's happening is there's a bunch of comparators in there as well. So I reckon what they're doing is uh, they've just got like a reference, um, somewhere and they're just, uh, basically using the Dax to then, uh, create a voltage reference which then they compare like under voltage? Um, like you know, like end of charge type? uh, level stuff. I don't think they're actually measuring it and that seems very strange. Why you'd limit yourself? I don't know why you wouldn't go for a full Adc Dac solution.

I'm not sure what the deal is, but damn it, I can't find there is no Adc. There is no Adc. I swear it's not here. I've got to presume that they've got an Adc solution in there.

so they're probably using the 8-bit dac in there as a, uh, successive approximation. uh, converter? perhaps? Um, and the power supply down there? Well, that's a bit how you doing? Um, yeah. exposed cabling. Everything like, like the grounding is fine.

Like you know, it's fine. It's just like, you know, lacking a little bit of um, spit and polish. but you know it's it's good enough for the era. I guess there's a better framing shot of the top half there.

And yeah, we have a date code on this of uh, 497 so 1997. The manual had 2005, but as we'll see in the manual in a minute, Um, yeah, you know how I had those complaints about the thermals in this thing? It looks like they took my uh opinion on that and they fixed it way back in like the 2000s. So yeah, this is an older model of the I presume, a much older model of the Uh C7000 series. All right, let's power this thing up.

I've got my 110 volt transformer, so let's give it a bill. I don't know when it was last used, but here we go. Hey Flushy Flash Copyright 95 2000 Version 3.5 Something Empty Bat Shop. Don't you hate it when your bat shop's empty? So you press the S1 button? Uh, looks like it was previously used for 7.2 volt Nicad 1500 milliamp hour? Um, that's I don't know.

Is that like the last serial number or is that the oh yeah, oh, Lithium ion? There you go. 3.6 Nicad and a Lithium ion there? I assume that's just some generic thing and um, did what charge discharge right? Oh no. These are arrow keys. Oh oops.

Okay, so once you're in, these are okay. that's that's confusing. All right. Yeah, yeah.

there we go. Up and down. Okay, I thought like this would just run a like. S1 would be the primary function to just run like a a macro.

or you know, go through its pre-programmed thingamabob Capacity offset. There you go. Temperature sensing Max uh, standby Voltage Max Charge Voltage End of charge, End of discharge. So menu.

There you go. Security Mess System: Security: Yeah, yeah I thought so. Yes, you don't want people around with this Voltage display, sound control, output devices, Calibration There you go. Okay, so if we go to this lithium ion one, press C code to edit and bingo we're in.

Can We? Yeah. Sla There you go. Sealed Lead acid, Lithium ion, Nicad, Nickel metal Hydride. They're the pre-programmed Okay, check this out.

It is actually monitoring all the time. and when you plug in the battery, there you go. Well, no Bat shops moved up the top. So yeah I guess we can.

Then Bat Shop mode S3, Bat shop mode Weight So if I type 3 7, 0 enter it goes back to 3.6 Why is it? Lo? Is it because it's locked and I can't change it? How do we run it? I should. Rtfm shouldn't I? Obviously this is not designed for just you know, walking up and using kind of thing. Um, yeah, as I said, it's designed for like all, um, pre-programmed factory production and service testing and stuff like that. Okay, I just figured out what Bat Shop means.

Bat Shop is the battery. uh, shop software. Uh, Pc based software that they've got. So obviously it's in like Pc interface mode or something.

I think that's why it's not letting me do anything but why I can't just manually start. I don't know. Whoa. The fan just ramped up so it's temperature controlled.

I didn't do anything, I haven't started anything anyway. Um, yeah, it's clearly designed for the Bat Shop. Uh, software. I couldn't find any option in there to like, uh, you know, reset to factory defaults to disable Bat Shop or whatever.

But yeah, it. I think it requires quite a significant, uh, amount of um, time investment to try and figure out how best to use this thing. Um, and download the software and all that sort of stuff. This video has been long enough.

It was just designed as a tear down so I have no doubt this thing will, uh, work. So yeah, if you want me to, um, have a play around with this, I'll put any videos on the second channel because I would actually like to get it up and working. So I would actually like to get the bat stop bat shop software working so I can get like crap maybe discharge grass and you know, stuff like that measure battery capacity and cell resistance and all sorts of stuff it can do a real fancy panties. So yeah I'll try and get that all uh set up.

but that's it for this video so I hope you like that interesting bit of uh industry kit. If you did, please give it a big a thumbs up. As always, discuss down below: catch you next time you.
