The invention discloses a charging protection device for a lithium battery of a battery car. The device comprises a charging pile, and an adjusting cavity is formed in the charging pile; an adjustingdevice for changing the charging current by changing the resistance is arranged in the adjusting cavity; the adjusting device comprises binding posts which are fixedly connected with the inner wall ofthe right side of the adjusting cavity and are vertically symmetrical. A rheostat which can be adjusted in a sliding manner is adopted, a power extension shaft is arranged in the timer, under the transmission of the gear pair and the sliding pair, the switching of the charging mode is controlled by adopting the time ratio of the gear engaging and separation engaging, the lithium battery is charged more reasonably, and moreover, after an adjusting block under a sliding pair triggers a pressure sensor for a certain period of time, a mechanism of a bidirectional clamping charging head part slides to separate a plug from a socket, so that a connecting part is prevented from conducting electricity and generating heat, and the situation of combustion explosion is avoided.

    本发明公开的一种电瓶车锂电池的充电保护装置,包括充电桩,所述充电桩内设有调节腔,所述调节腔内设有变化电阻改变充电电流大小的调节装置,所述调节装置包括与所述调节腔右侧内壁固定连接且上下对此的接线柱,本发明采用都可以滑动调节的变阻器,通过计时器内的动力延伸轴,在齿轮副与滑动副的传递下,利用齿轮啮合与脱离啮合的时间比控制充电模式的切换,更为合理的对锂电池充电,另外,滑动副下的调节块触发压力传感器一定时间后,双向加持充电头部分的机构滑动将插头与插座分离,防止连接处导电生热,避免燃烧爆炸的情况发生。
