Battery evaluation device

Achieve accurate battery capacity measurement with a high precision of ±0.02% for voltage and current! Leakage current during constant voltage charging can also be measured!

The "High Range High Performance Charge and Discharge Device" is a charging and discharging device that uses a dropper-type power supply and subdivides the current range into eight ranges. This allows for more accurate measurement of battery cumulative capacity compared to conventional methods. Additionally, by automatically and seamlessly switching the current range during current attenuation under low voltage control, it enables measurements without compromising accuracy or resolution even during constant voltage control at high currents. Furthermore, it is also capable of measuring leakage current during constant voltage charging. 【Features】 ■ Voltage and current accuracy of ±0.02% due to the dropper-type power supply. ■ Accurate battery cumulative capacity measurement with eight ranges. ■ Independent control of 6 channels per case. ■ Current auto-range function with semiconductor switching (range switching time approximately 20 ms). ■ Capability to measure leakage current during constant voltage charging. *For more details, please refer to the catalog or feel free to contact us.
