Bq34z100 怎么判断电池是充电还是放电

现在用mcu去和bq34z100做通信，mcu需要知道电池是空闲还是充电还是放电，去做相应不同的处理

8.3.1.8 AverageCurrent(): 0x0A/0x0B This read-only command pair returns a signed integer value that is the average current flowing through the sense resistor. It is updated every 1 second with units of 1 mA per bit. However, if PackConfiguration [SCALED] is set then the units have been scaled through the calibration process. The actual scale is not set in the device and SCALED is just an indicator flag.

您好，根据手册15页的描述，发送AverageCurrent()指令，通过读出来的电流的正负就可以确定是充电还是放电

这个我看过，正负只有两种状态，但我还要判断充电，放电，空闲，有三种状态，能不能加个电流大小去判断空闲状态。但是为什么空闲的时候也有几十毫安的电流 ，如果不加电流大小判断，导致我空闲时也判断成放电了

空闲状态下电流应该为0，检查硬件电路是否漏电，并在bqstudio里做校准
