The invention discloses a lithium battery low-temperature charging device with charging protection, and belongs to the technical field of low-temperature charging. A lithium battery low-temperature charging device with charging protection comprises a charging pile body, a charging area and a driving area, the charging pile body is arranged at one end of the charging area, and the driving area is arranged at the other end of the charging area. In order to solve the problems that the internal resistance of a battery is increased at low temperature, cut-off voltage can be reached in advance during low-temperature charging, the chargeable capacity is greatly reduced, the risk of separation and formation of negative electrode lithium dendrites is increased, and the safety of the battery is further damaged, the whole charging pile adopts incremental trapezoidal charging, and the internal resistance of the battery is increased at low temperature; the low-temperature charging can reach the cut-off voltage in advance, so that the chargeable capacity is greatly reduced, the risk of separation and formation of negative electrode lithium dendrites is increased, and the safety of the battery is harmed, and the progressive increase type trapezoidal charging can adjust the output current of the charging gun according to the temperature of the battery, so that the optimal charging process is realized.

    本发明公开了一种带有充电保护的锂电池低温充电装置,属于低温充电技术领域。一种带有充电保护的锂电池低温充电装置,包括充电桩主体、充电区和行驶区,所述充电桩主体设置在充电区的一端,行驶区设置在充电区的另一端。为解决低温下电池内阻增大,低温充电会提早到达截止电压,导致可充入容量大幅减少,并且增加负极锂枝晶析出和形成的风险,从而更会危害电池安全的问题,充电桩整体采用递增式梯形充电,低温下电池内阻增大,低温充电会提早到达截止电压,导致可充入容量大幅减少,并且增加负极锂枝晶析出和形成的风险,从而更会危害电池安全,递增式梯形充电可以根据电池温度来调节充电枪的输出电流,实现最优化的充电过程。
