Features
1. In an isothermal environment, it is compatible with the power compensation method and the heat – flow method to measure the heat generated during battery charging and discharging. This not only ensures the accuracy of thermal characteristic measurement for relatively large – sized batteries but also improves the sensitivity of heat measurement for relatively small – sized batteries.
2. It has an instrument calibration mode, which can calibrate the measurement accuracy of charging and discharging thermal behavior parameters under different conditions.
3. It is equipped with a heat capacity measurement mode. By using the comparative method to measure heat capacity, it reduces the operational requirements for heat capacity testing and can accurately measure the heat capacity of batteries at different temperatures.
4. The integrated battery charging and discharging module enables the switching of charging and discharging modes, the setting of constant – current/constant – voltage charging modes, the setting of charging/discharging currents, and the real – time calculation of battery power.
5. Network communication is adopted to achieve remote operation of the instrument and remote data transmission, ensuring the safety of testers.
6. It can simultaneously record voltage, current, and temperature data during the battery charging and discharging process.
7. An optional nitrogen purging module can be selected to ensure the accuracy of low – temperature measurement and effectively suppress the problem of low – temperature condensation.
