HV Battery problem #23

Closed dgn555 closed 4 years ago

dgn555 commented 5 years ago

I have this errors

U01a2FA can communication with the internal control unit for monitoring the battery cells (C) is fault P14f300 The internal function of the high voltage battery module have been deactivated due to cell voltage being love P0a0e00 The interlock of the high voltage on-board electrical system has a aporadic malfunction P0de6fb the cell voltage of high voltage battery module are too low P0de6fa the cell voltage of high voltage battery module are too low P18051C the hardware monitoring function has detected fault in the control unit. The voltage value is outside the stored permissible range here is my logs

Is someone can help me? what must i do? only charging cells one by one is enough to fix?

the error P18051c U cannot erase it, there is same cell

12;3013;18727 83;2285;18727

u must check this

dgn555 commented 5 years ago

I am charging all individual cells to 3500 mvolt, shall i need to do anything else?

minorukurata commented 5 years ago

charge up to 4.1 volt there is a posibility that the cell is weak so is unbalance the entire pack

another thing is the DTC P18051c cannot erase it only I know a company called softelectronic it does

dgn555 commented 5 years ago

May i learn the amperage of the batteries please, for individual cell? 4.1 volt and how much amper?

minorukurata commented 5 years ago

normal AH of each cell is 53AH,

dgn555 commented 5 years ago

i limited it with 15A is it will be safe or not?

minorukurata commented 5 years ago

capacity is 53AH you can charge normally at 1C = 53A so the internal charger is 3.3kw so its charge at 10A
