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 1.5A once the voltage reaches 355V and does not increase beyond that. Could you help me understand what might be causing this issue? I have attached a copy of my parameters for your reference.

Please provide a CAN log too.

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

If u disconnect the bms, will it keep charging? What size battery was the bms from?

You set "BMS_Mode": 0

Yet you have a Leaf BMS?

What firmware version are you on?

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

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

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