| Abstract: | A system with the functions of on-line monitoring and high-power constant current discharge intelligent load for storage batteries is designed in this paper. The system is based on single-chip microcontroller to control the constant-current discharge, measure and record the batteries＇ voltage, discharge current and system temperature during discharging. And it adopts pulse-width modulation control technology, which has high precision in the discharge current control and can keep the discharge current stable. By this method the disadvantages of bad stability and controllability for positive temperature coefficient load can be avoided. |
