Thanks for the clarification. I've placed the order for the capacitors—they should arrive within 10 days. I’ll update you once they’re here

Thank u

I swapped one module into my 64S pack and it works. Of course that doesn't say much as the old one worked as well.

To patch modules to this state first install this software: https://github.com/jsphuebner/FlyingAdcBms/actions/runs/15473329191
Never run a v2.4 BMS or one patched to that state ...

Ok, interesting approach. Yes they'd need something along the lines of this https://openinverter.org/forum/viewtopic.php?t=1351 or that https://openinverter.org/forum/viewtopic.php?t=6361 to isolate them from each other and still have communication.

Or just wait and see if we found the culprit ...

No, the current sensor must be connected to the first board and transmits its value to the other ones via CAN


That's not how it is designed to work. E.g. for balancing each board needs to know the min/max/avg cell voltages of the others. Why are you not doing the CAN interconnection?


The ...

I have a battery pack with 96 cells.

I'm trying to run them without interconnecting the BMS boards directly. According to the [Wiki], it says:
"The BMS will then keep running as long as current flows through the battery. Two hours after it has measured the last current flow, it will shut down ...

It appears that resistor R6 was faulty. After replacing it, everything worked

Hello,

A few months ago, I purchased a vacuum pump control board from the webshop. I've connected it as described below, but the pump isn't starting.

Wiring Setup:
12V and GND from the board → connected to the battery positive and negative, respectively.

OUT from the board → connected to the ...

it has worked .thank you

I recently received six ADC16 BMS boards and an ESP32 board from the OpenInverter shop. For testing, I connected one BMS board following the instructions on the wiki:

ENAL_IN and 12V connected to a 12V power supply
GND to GND
BMS CANL to ESP32 CANL
BMS CANH to ESP32 CANH

I successfully connected ...

Thank you . Have tried it and it has worked

The resistor in your image is 35 ohm, not 350 ohm. At 400v there is 4500 watts acting on it initially.

Tom's recommendation has 1600 watts as the initial hit.
These both sound huge but are short duration.

These both have wattage taper down as the voltage delta drops over time. You can use https ...

tom91 wrote: ↑Fri May 02, 2025 8:16 am I tend to just use an oversized 100watt 100 ohm resistor. Most builds do not need a low resistance precharge.

Thank you tom91 . I tried 100W 40 ohms and that didn't even last for 10 minutes

Hello,
In my EV conversion project using a Zombieverter, Nissan Leaf drivetrain, and a 400V battery pack, I’ve been using a 50W 35ΩJ resistor as part of the pre-charge circuit. However, the resistor works for a few days before failing—I’ve already replaced it three times.
I would appreciate your ...

Parameter idcmode to AdcSingle

I think the Leaf sensor outputs an asymmetric signal. So at 0A it sits at 3.2V or so. Can be adjusted with idcofs

Thanks a lot

Hi all,

I have a Leaf current sensor (Hall effect type) with three wires: GND, Voltage, and Signal (current output). I'm trying to connect it to the Flying ADC 16 BMS, but I'm a bit confused about the proper wiring.

I've been reading through the documentation here:
🔗 https://openinverter.org/wiki ...

Thanks! I just setup github account at https://github.com/RERides-EV. I've made some mods to your code. Goal is to create modules based on controller/device. I can then #include modules for each component I add to a build. For this build, in addition to the Leaf AC compressor, I plan to add temp ...

I've finally figured out the problem—it was with the EVS. After replacing it, the charging works as expected

Yet you have a Leaf BMS?

What firmware version are you on?

I disconnected the bms . Am using the latest firmware 2.20A

I disconnected the bms. It was a 24kw bms but am planning to buy flying ADC bms

Also what generation of Leaf PDM? What is the battery pack and BMS?

gen 2 PDM, l connected 24 catl modules (4S1P, 180Ah,nominal voltage 14.8) and leaf BMS. Am going to log CAN later and l send

Hello,

I have a Zombiverter VCU and a 3.6kW Leaf PDM that I am using to charge a battery pack. The battery is supposed to be 72kW when fully charged (400V * 180Ah) and 64kW at nominal voltage (355V * 180Ah). However, when charging with the EVSE set to 15A, I noticed that the current drops to around ...

Hello,
I’m planning to switch to this BMS. What type of temperature sensors does it use, and can Nissan Leaf sensors be compatible with it?
