The vacuum cleaner battery charging and discharging life tester is used to monitor the long-term and interval charging and discharging aging tests of vacuum cleaner battery products. It independently simulates actual charging for 20 battery positions through external programmable power supply. Aluminum resistors serve as adjustable loads to discharge the batteries. The tester uses PLC and current acquisition modules to collect and judge electrical parameters such as voltage and current changes during charging and discharging of 20 channels. Through relevant parameter settings, the PLC displays and records in real time the changes in parameters such as voltage, current, resistance, capacity, temperature, as well as charging and discharging time and test times for each position, and performs data recording and USB data export
