Leaf busbars and cabling

I have a bunch of Leaf/EV200 busbars that I'm about the recycle (cut the copper out of them).
If anyone is interested in something let me know.

Re: Shell closes its light-duty hydrogen refilling stations in California

They (Shell) just recently opened an new hydrogen station next to the highway exit on the A15 in The Netherlands. In fact they are still working on it and it is not fully finished yet. But the white hydrogen 'rocket' is clearly visible and trucks are pumping something (I guess diesel actually). Not ...

Re: 120v lithium battery charger required

I think I have one, it is an Elcon something... setup for 120ish volts but can be adapted. Let me know if you are interested. I'm travelling to the UK next week so can bring along if wanted.

Re: J1772 Type 2 and Brusa NLG513

Do i get this right that the EVSE can activate the charger? Without communicating via can with the bms, how does the charger know what the BMS suggests as charge limit concerning battery temperature too high or too low, single cell voltages too high or too low and so on? No, the charger always acti...

Here i convinced EVSE to open and supply AC at 16A. I wired one 2K7 resistor and additional switch and 1K3 resistor to PE that brings total CP resistance to some 880R. I did that inside the handle. Charger then started CAN telegram from PP present signal which pulled some input pin on my CAN uC to ...

Re: J1772 Type 2 and Brusa NLG513

Yes the NLG5 does support it,
There is a CP (ControlPilot) input connection available to be direclty connected to the EVSE.
You have to trigger the signal though by means of a CANbus message.
I never got it working properly in 'stand-alone' mode (without CANbus) but with it works fine.

I would be interested in joining up with anyone looking at the BMS24 and possibly EVMS3 if it helped for bulk ordering! 'Bulk' at this time is limited to about 25 or 30pcs because of the stock they carry. I initially had 30pcs of the BMS12 but when finalizing the order just one component had only a...

I believe PCBWay supports having you sent them the missing parts so they can install them for you ? With the BMS12 I only have to flow the atmega, ltc1602 and solder the non-smt connectors which should be doable. After the BMS12 units have arrived somewhere next week I'll look into the other BMS par...

Re: ZEVA has gone "open sorce"

I have finalized the order for a first batch of 25 units BMS12 (without the 3D printed housing but STL file is available).
Prices wil be around 50 - 60 euro per 12 channel module.

That's a nice way to end a business. The designs look quite DIY friendly with 3D printed cases and cheap, minimal parts.

Re: Regen blows charger fuses ??

Could it be some sort of over voltage protection on the charger output? This Elcon charger is capable of charging upto 198Volt so I cant imagine any like that.

Re: Regen blows charger fuses ??

Have you measured the actual voltage at regen? Maybe the charger sees overvoltage and wants to discharge the battery. Does it get powered up in a way that would make this possible? Well, in any case, one possibility could be that the charger has high enough capacitance at the output and the inverte...

Re: Regen blows charger fuses ??

Just put a diode on the charger output. Maybe that is built in on your other charger. Yes I have thought about that but then the charger probably wont see that a battery is connected when starting to charge. Maybe connecting a diode with a 10K resistor in parallel so it can sense that battery volta...
