Problems solved by technology

If the charging and discharging current of the battery is too large, it will easily cause potential safety hazards in the circuit. If the charging and discharging current of the battery is too small, the charging and discharging efficiency will be low.

Most of the battery charge and discharge current detection circuits in the prior art are relatively complicated, and cannot detect whether the battery is in a charging state or a discharge state, and are not compatible with different current acquisition devices, which makes the application of the battery charge and discharge current detection circuit subject to certain restrictions. limit

And the detection accuracy of the charging and discharging circuit is difficult to guarantee
