Abstract

The invention discloses an explosion prevention and fire extinction testing device for a lithium ion battery. The device comprises a base 2 and a protective shell 9, and is improved in a way that a battery 1 is arranged between the base 2 and a cavity of the protective shell 9, and the cathode and the anode 14 of the battery are connected with testing terminals 12 on charging and discharging test lines 3; the base 2 is provided with a temperature controlled switch 4 which comprises a temperature sensor 6 and a signal line 5; the temperature sensor 6 is connected with the lithium ion battery 1. According to the explosion prevention and fire extinction testing device for the lithium ion battery, a high-temperature abnormal phenomenon can be timely sensed, a circuit can be timely, rapidly and effectively broken to reduce the temperature of the battery, and meanwhile, inert gas can be emitted to isolate the battery, so that the lithium ion battery can be prevented from being exploded and burnt due to high temperature.

Description

technical field [0001] The invention relates to a safety test device, in particular to an explosion-proof fire extinguishing test device for a lithium ion battery. Background technique [0002] With the development of microelectronics technology, miniaturized equipment is increasing day by day, which puts forward high requirements on power supply. Lithium batteries are widely used in many aspects due to their excellent performance in many aspects, such as mobile phones, handheld computers, notebook computers, power tools, electric vehicles, street lamp backup power, navigation lights, video cameras, cameras, small household appliances and even Military equipment and satellites. Lithium batteries are also known as "the most promising chemical power source", and even called "extreme batteries" or "last generation batteries". [0003] In addition, from the perspective of environmental protection, due to the presence of cadmium, mercury, lead and other elements in battery raw ...
