Re: Switched ADC BMS

Hey Johu, any recommendations on a suitable wire-to-board connector for the 17pincell tap connection? I've looked on JLCPCB and LCSC but neither seem to have something suitable to my inexperienced eyes. what is the max voltage rating required? do they need to be 400V rated or not? failing a wire-to-...

Re: [ WIP ]Bmw e39 + GS450h

Red to W, white to V black to U.

Do you have the controller wired correctly also?

1 blue
2 green
3 yellow
4 red
5 black

Then the big connector on the controller needs the black PWM wire to the zombie and 12V with the controller body being grounded.

I might be wrong here but I think the prams database is a local thing to you rather than on a server elsewhere. If it's not working, it will be something local to your setup.
I'm wrong.

Re: Nissan Leaf BMS

A question, will the BMS report voltage for just 1 cell for testing purposes? It would be nice to have it setup spitting out CAN and then connect cells one by one and see the voltages show up on leaf spy.

Re: Nissan Leaf BMS

The BMS cannot limit anything, it only measures voltage and current and it will balance the cells 24/7 as long as it receives +12V on pin 5 (BAT) of the round connector, which is wired to pin 12 of the LB11 connector. Also, all 96 pairs of cells need to be plugged in obviously. The BMS will only co...

Ok so this is a great start for wiring things up, although interestingly my LS11 connector has an extra wire that's not shown on this diagram on pin 11.

Re: Nissan Leaf BMS

Ok, so anyone got a TLDR; for how to use the leaf BMS from a 40kWh pack? One arrived today, I suspect I'm going to have to do some digging. I've read a lot so far but nothing super conclusive for my tired brain. Can I just hook up 12V, Gnd, CanH and CanL and get data via a Bluetooth dongle and leafs...

Re: [WIP] Mercedes 310E (310D campervan) - GS450H/GS300H

Thanks, I think for the leaf BMS it needs to be broken at cell 48 for reasons I don't understand but also to avoid 'popping'. The single/double battery box (with a solid corridor above the prop) might be a good idea actually. It would protect all the cabling, keep the number of input and output conn...

Re: [WIP] Mercedes 310E (310D campervan) - GS450H/GS300H

You need to figure out which are the supply voltage pins, e.g. with a 50 mA current limited 5V supply. When a third pins spits out around 2.5V you've nailed it. Is this likely applicable to both sensors or just the LEM hall effect one? From the data sheet the LEM one is only suitable for 300V so no...

On another note, current sensors. Are they easy to reverse engineer? I've got my hands on 3, one from the Lexus UX300E pack and another 2 from a random contactor setup I bought for cheap one of which is a low voltage LEM one. I don't know the parameters for any of them but it'd be nice if I could re...

Anyway, if I can manage to mount the disconnect I...

I've got for a mirrored pair either side of the prop shaft. To do this I can keep all the battery modules as t...

We have a load of the bms modules removed from jag ipace packs.

Part number is J9D3-10C802-AB

They are of no use to us at work, but if anyone wants them let me know. No idea on price but they will be cheap.

If the diodes fail, it means they are outside of their design operational window. Thus any other components on those sense lines will be hit hard by what ever voltage caused that failure.
