Step S109, discharging by using the first discharge current and recording the voltage and current values at the moment, and after the step is executed, executing step S110;
in step S109, the first discharge current is 0.05C, the output voltage is controlled by the parallel power module processor, so that the discharge current of the battery is constant current 0.05C, and the corresponding voltage and discharge current value of the battery are recorded when the discharge current is constant current 0.05C, for example, a 12V 100AH maintenance-free lead-acid battery, and the corresponding discharge current of the battery 0.05C is 5A.
Step S110, discharging by using a second discharge current, recording the voltage and current values at the moment, and executing step S111 after the step is executed;
when step S110 is executed, the second discharge current is 0.1C, the output voltage is controlled by the parallel power module processor, so that the discharge current of the storage battery is constant current 0.1C, and the corresponding voltage and discharge current value of the storage battery when the discharge current is constant current 0.1C are recorded, for example, a 12V 100AH maintenance-free lead-acid storage battery, and the corresponding discharge current of the storage battery 0.1C is 10A.
Step S111, finishing the internal resistance test, and calculating the internal resistance of the storage battery according to the current and resistance values obtained in the step S109 and the step S110;
