Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the battery pack of an electric vehicle supplies power to the motor and charges the battery pack, the battery will be deformed due to the instability of the internal material, and the single battery inside the battery pack will swell due to excessive deformation. A new type of lithium battery charge and discharge deformation test system is provided due to the lack of short circuit accidents

Abstract

The invention provides a lithium battery charging and discharging deformation test system. The system comprises a deformation test support, a battery measuring device, rapid clamping mechanisms and a probe device, wherein the battery measuring device is arranged at an upper part of the deformation test support, the rapid clamping mechanisms are arranged at the two sides of the bottom of the deformation test support, and the probe device is arranged at one side of each rapid clamping mechanism. The system is advantaged in that the deformation testing support on the deformation testing system has the function of simulating the initial pressure provided by the battery pack and is fixed by the locknut; the rectangular spring and the dial indicator are matched to test the deformation of the battery in the charging and discharging process; a rapid clamping mechanism is arranged on the deformation testing system so that testing rapidness and stable contact of charging and discharging are realized; one side of the dial indicator is provided with a measurement data output end, communication with charging and discharging equipment can be realized, and the linear relation of the charging current under the condition that the deformation quantity of the battery and the extrusion force are increased in the charging and discharging process is monitored in real time.

Description

【Technical field】 [0001] The invention relates to the technical field of a deformation testing system, in particular to a lithium battery charging and discharging deformation testing system. 【Background technique】 [0002] In the environment where the country advocates green travel, electric vehicles are regarded as the main way of travel in the future. The electric vehicle is equipped with a battery pack module that can store electric energy to provide energy for the motor. Due to the instability of the battery pack, the safety of the battery pack for electric vehicles is also the main research direction. [0003] When the battery pack of an electric vehicle supplies power to the motor and charges the battery pack, the battery will be deformed due to the instability of the internal material, and the single battery inside the battery pack will swell and short-circuit due to excessive deformation. The main source of danger, the detection of deformation of the battery in the ...
