Introduction When testing lithium batteries, what does parameter C mean? How is it defined? In lithium battery testing, C is used to represent the ratio of the battery's charging and discharging current, i.e. rate. Charge-discharge rate = charge-discharge rate

When testing lithium batteries, what does parameter C mean. How is it defined?

In lithium battery testing, C is used to represent the ratio of the battery's charging and discharging current, i.e. rate. Charging and discharging rate = charging and discharging current/rated capacity. For example, for a 1200 mAh battery, 0.2 C represents 240 mA (rate of 0.2 for 1200 mAh) and 1 C represents 1200 mA (rate of 1 for 1200 mAh). 3C lithium battery testing requires the use of battery test modules, such as shrapnel micro-needle modules, which can transmit large currents well, with a maximum current of 50A, stable connection and no attenuation. current, which is beneficial for 3C lithium batteries. Testing is complete. effectively.
