Abstract

The invention discloses a device of testing thermal runaway of a lithium ion power battery. The device comprises a front clamp plate (1) and a rear clamp plate (2) that are vertically arranged at intervals front and back, wherein a first thermal insulating plate (11) and a second thermal insulating plate (12) are fixed on opposite sides of the front clamp plate (1) and the rear clamp plate (2) respectively, a position between the first thermal insulating plate (11) and the second thermal insulating plate (12) is used for placing a to-be-tested battery, a heating plate (9) is embedded in centers of the front clamp plate (1) and the first thermal insulating plate (11), the to-be-tested battery and an analog voltmeter (6) are connected, and a temperature probe of a digital thermometer (7) isembedded in centers of the second thermal insulating plate (12) and the rear clamp plate (2). The device can test thermal runaway of the battery conveniently and reliably, collects output voltages ofthe battery when surface temperature rises in real time so as to acquire performance of the battery accurately, thereby ensuring security performance of the battery.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a thermal runaway testing device for a lithium-ion power battery. Background technique [0002] At present, lithium-ion power batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras and laptop computers, but also widely used in electric vehicles, electric In terms of large and medium-sized electric equipment such as bicycles and electric tools, the performance requirements of lithium-ion power batteries are getting higher and higher. [0003] For lithium-ion power batteries, due to their light weight, small size, large capacity, high power, and no pollution, they have become ideal power sources for electric vehicle batteries. During the production process of the battery, it is necessary to test the performance of the battery, among which t...
