Basic Composition of Charge-Discharge Test System for Electric Core
The core charging and discharging test system is mainly composed of power supply, electronic load, data acquisition and control unit and upper computer software. The power supply is used to provide charging current for the electric core, and the electronic load is used to simulate the load condition of the electric core in the process of discharging. The data acquisition and control unit is responsible for real-time acquisition of voltage, current and other parameters of the battery cell, and data processing and analysis through the host computer software.
Charge-discharge test process of electric core
In the process of battery charging and discharging test, it is necessary to charge the battery core first. The power supply provides constant charging current for the electric core, while the data acquisition and control unit records the voltage and current changes of the electric core in real time. When the battery cell is fully charged, the system will automatically switch to the discharge mode.
During the discharging process, the electronic load will simulate the load situation in actual use and discharge the battery cell. The data acquisition and control unit will continue to monitor the voltage and current changes of the battery cell and upload these data to the upper computer software for processing.
