The corresponding duty ratio of pressure difference between the voltage of core and average voltage；The determining duty ratio is corresponding as the battery core
The duty ratio of the pwm signal.Specifically, there are preset correspondences between pressure difference and duty ratio, such as：Pressure difference 1 corresponds to
Duty ratio 1,2 duty ratio corresponding 2 of pressure difference, etc..The present embodiment is flat the current voltage and N number of battery core for determining M battery core
After the pressure difference of equal voltage, that is, after determining M pressure difference, according to the correspondence of pressure difference and duty ratio, determine above-mentioned each pressure
Duty ratio corresponding to difference, and using the duty ratio corresponding to each pressure difference as the duty ratio of the corresponding pwm signal of the battery core, example
Such as：Pressure difference 1 is the difference of the voltage and average voltage of battery core 1, then by the 1 corresponding duty ratio of pressure difference, is determined as the correspondence of battery core 1
