BQ76952: 电池平衡问题

Part Number: BQ76952

Hi Team

我正在使用BQ76952,在电池平衡时,顶端CELL16应该要进行平衡,但总不进入平衡状态,这是为什么,有可能是什么问题,电池连接情况如下图,10节电芯串连,每次最多可进行5节电芯平衡。

Thanks.

  • 您好,可以通过下面指令确认cell 16可以balance

    Try host controlled for a specific cell (cell-16),Try this sequence:
    W
    : 10 383 00 00 80
    W: 10 60 FC 06

    Note: The command will have to be re-sent after 20 seconds. It has a timer where cell balancing stops automatically. Make sure Settings: Cell Balancing Config: Balancing Configuration: [CB_NO_CMD] is zero (this will allow host control).

    Measure the voltage across Rbal (R5) and also across VC16-15 pin of the FAE. The voltage will drop across the VCx pin if cell balancing is active.
