中文摘要：

本文采用加速量热仪与电池充放电循环仪联用技术,实时测量了钛酸锂电池在脉冲放电过程的电压、电流、温度、温升速率变化.电压曲线在脉冲过程及之后的静置时间内呈现先急剧下降再增加的变化。电池温度因脉冲的存在高于正常放电过程的温度,温升速率曲线在脉冲瞬间也急剧增大,但随着电池内部温度的增加,脉冲对温度、温升速率的影响减弱。此外,由于传热的滞后性,电池温度在脉冲瞬间并没有表现出明显的上升过程。

英文摘要：

An Accelerating Rate Calorimeter combined with battery charging aud discharging cycler was employed to study the variation of voltage, current, temperature, and temperature rate on lithium titanate battery dynamically during the pulse discharge. The voltage decreases quickly during pulse discharge, and then increases to a special value in the pause time. Due to the existence of pulse in the discharge, the temperature and temperature rate are higher. While the impact of the pulse process on the battery thermal response is weakened as the temperature inside the battery increased. Besides, there is no significant change on the temperature during the pulse because of the heat lag.
