BQ4050EVM-561: bq4050 shutdown或reset后,rsoc和remain capacity为什么不对?

Part Number: BQ4050EVM-561
Other Parts Discussed in Thread: BQ4050

测试时,发现bq4050 shutdown,重新充电唤醒后,电量的rsoc和remain capacity不是shutdown之前的值,而都是默认变为99%。如何才以能保持shutdown之前的rsoc或remain capacity值?

详细的操作如下:

step1:电池实际电量为rsoc=80%,remain capacity=3000mAh (电池容量为3750mAh);

step2:此时对bq4050进行shutdown;

step3:重新对bq4050进行充电,此时rsoc=99%,remain capacity = 3700mAh;

另外,发现reset命令,也有以上现象。
