Embodiment Construction
[0022] The method for preventing the explosion of the rechargeable battery during the test is as follows: (a) seal the battery to be tested in an explosion-proof box; (b) lead the connection point of the test battery to the outside of the explosion-proof box through the connecting circuit, and use (c) install a fire extinguishing device and a battery explosion detection device inside the explosion-proof box; (d) make the battery explosion detection device trigger the fire extinguishing device to extinguish the fire and cut off the connection between the test battery and the battery test equipment when the battery explodes. Connect the circuit.
[0023] Protection against explosion during testing of rechargeable batteries, e.g. Figure 1-3 As shown, it includes an explosion protection box 1, the wall of the explosion protection box 1 adopts double-layer steel plate structure, LED lighting is arranged in the explosion protection box, and a smoke exhaust channel 2 is arranged in ...

The invention discloses an explosion protection method and a device when testing a rechargeable battery. The rechargeable battery to be tested is sealed into an explosion protection box, and a terminal point of the rechargeable battery is led to outside of the explosion protection box used for connecting a rechargeable battery testing device. A fire extinguishing apparatus and an explosion detection device are arranged inside the explosion protection box, thus when the rechargeable battery explodes, the explosion detection device triggers the fire extinguishing apparatus to put out a fire, and cuts a junction circuit of the tested battery and the rechargeable battery testing device. The invention has the advantages of simple operation, safety, low cost, capacity of guaranteeing safety of staff, protecting the rechargeable battery testing device, and preventing short circuit of the testing device caused by battery explosion.
Description
technical field [0001] The invention relates to the production and inspection technology of a rechargeable battery, in particular to a method and device for preventing explosion of a rechargeable battery during charge and discharge tests. Background technique [0002] Lithium-ion and other rechargeable batteries are now widely used in mobile phones, toys, electric bicycles or other daily necessities. my country is a big country in the production and sales of rechargeable batteries, with a huge export volume. According to the requirements of GB / T18287 and other standards, it is necessary to conduct high-current charge and discharge tests on rechargeable batteries. In the past test process, battery explosion and fire accidents occurred many times, which seriously threatened the safety of test personnel and test equipment. As far as we know, there is no protection method and device for battery explosion during the rechargeable battery test. Contents of the invention [0003...
