Abstract

The invention discloses a battery anti-sparking control method and a battery anti-sparking circuit. The battery anti-sparking control method comprises the following steps: switching on a first switch module; detecting the current of a branch where the first switch module is located based on the current sampling module and the first resistive module to obtain a first current; when the first current is smaller than the first preset current, the first switch module is turned off, and the second switch module is turned on; based on the current sampling module, the first resistive module and the second resistive module, the current of a branch where the second switch module is located is detected, and a second current is obtained; when the second current is smaller than or equal to the second preset current, the first switch module is kept switched off and the second switch module is kept switched on; and when the second current is greater than the second preset current, the first switch module is switched on again. The battery anti-sparking control method provided by the embodiment of the invention is beneficial to reducing the cost required by battery anti-sparking.
