Research on the Activation System of Lead-Acid Battery

Abstract:

For the valve-regulated lead-acid (VRLA) battery, an on-line activation system is designed, which is composed of personal computer (PC), sixteen bits MCU, touch-screen, mass FLASH memory, ferroelectric random access memory (FRAM), Ethernet interface, USB interface, charging module, discharging module, and so on. The charging module is designed based on distributed power supply with low voltage and large current, and using the method of intelligent segmentation-limit-current to realize nondestructive charging. The discharging module is designed with technologies of PID and PWM, and battery discharging with constant current can be realized by controlling the power switches. Test results present that the system runs stably, can activate and repair the battery well in the early days of losing efficacy.
