Abstract

The invention discloses a charging device capable of popping up a lithium battery in case of abnormal expansion. The charging device comprises a working box body, the working box body is internally provided with a working cavity, and the working box body is internally provided with an elastic cavity located in the lower side of the working cavity. The charging device can seal the lithium battery in the charging process, so that the lithium battery can be protected to a certain extent; meanwhile, when the lithium battery expands in the charging process, the sealing state of the lithium batteryis immediately relieved, and the lithium battery is popped out of the device, so that the device is protected while accidental explosion caused by continuous charging of the lithium battery is prevented, and the charging assembly is prevented from being damaged by accidental explosion of the lithium battery; and the safety of the charging device is maintained to a certain extent.

Description

technical field [0001] The invention relates to the field of workpiece turning, in particular to a charging device for ejecting lithium batteries due to abnormal expansion. Background technique [0002] Overcurrent protection is a protection method that activates the protection device when the current exceeds a predetermined maximum value. When the current flowing through the protected element exceeds a preset value, the protection device activates to trip the circuit breaker or give Alarm. [0003] During the overcurrent protection of the circuit by the traditional overcurrent protection device, the important load is disconnected together with the secondary load, which has certain damage to the work of the important load and the load itself, and when the circuit is disconnected, it cannot Accurately know whether the cause of the overcurrent of the circuit is due to excessive load or short circuit, which will increase the troubleshooting workload of the staff. The present ...
