Part Number: BQ4050

Tool/software: WEBENCH® Design Tools

We are 13 cells synchronous equalization problem, we use 4 bq4050. The first 4050, read four cores; only these four equalizers, the second, the third and the four 4050 are read three cells respectively, total of 13 cells, but also can only correspond to several cells equalization, can not be synchronous equalization together with 13 cores.

    If you are talking about balancing the cells in series, you need a GND reference. The gauges don't stack and therefore can't be connected in series. Therefore you won't be able to balance the higher cells connected to gauge's that don't have a direct connection to GND.
