The limit voltage is 60V, the current is 40A. At the end of charging the current is 30A…60-60.8 is a limit value deviation so it could be 60.1, 60.8, 60.3 depend on the every pcs
I have 16kWh. One cell is 3,25Ah.
The space is enough, but i move battery 2 cm down below the frame. there is enough space but BMS is outside (my own BMS)…inside battery there are only LEM sensors and contactors and termistors
You can add more cells if You cut the fixing points and add new on the frame - You save in this case additional space for 15s10p module, but I decide to stay with my 16kWh…it it more than twice than original battery
This was a reason that I have high energy low current cells, so to have possibility to use 30kW in the peak on the rear wheels there is only one way…increase capacity to reduce C-rate
CAN frames…whow…a lot of…for example Charger wake BMS up…more over first start Charger send info “overvoltage test” BMS must open contactor on the “ECU OK”, send another frame and after that Charger send new info and BMS should turn ECU OK one more again
Sevcon could be turn on by wires…We do this at the beginning…in DVT Customer we found many errors of CAN frames…it was from the charger
