AI Technical Summary
Technical Problem
In a parallel dual-battery structure, the different aging characteristics of the batteries and the differences in their internal resistance and capacity lead to mutual charging, which affects battery life and performance.
Method used
By detecting the battery voltage, the battery with the higher voltage is selected as the target battery and connected in parallel or series for power supply. The current limiting module is used to share the voltage difference and optimize the battery power supply path to reduce mutual charging time and frequent switching.
Benefits of technology
Extends battery life, reduces aging rate, improves energy efficiency, and protects battery and circuit components.
