Overview
It is a kind of charge-discharge cycle test system integrating the charge-discharge cycles test, battery pack functional test and charge-discharge data monitoring. This test system is mainly applied to the high-power battery pack, such as the battery pack of EV, electric bicycle, power tool, gardening tool and medical equipment etc.
Application
The equipment can be applied to the Li-ion battery pack of electric bicycles, power tools, gardening tools and medical equipment etc. The charge and discharge voltage of the test system are up to 65V, the cycling current up to 20A.
Test items
1. Battery charge learning test
2. Battery discharge learning test
3. Over-current protection monitoring during discharge
4. Battery capacity monitoring
5. Voltage, current and temperature monitoring during cycle test
