Abstract

The invention relates to an acceleration test device and a test method. The acceleration test device comprises a test bench; a test vehicle, movably arranged on the test bench, the test vehicle comprising a vehicle body and a mounting seat arranged on the vehicle body, and the mounting seat being used for mounting a battery pack at the bottom of the vehicle body; an energy absorption assembly arranged on the test bed, and the energy absorption assembly corresponding to the end part of the test vehicle. When the test vehicle moves along the test bench, the energy absorption assembly can be in contact with the test vehicle so as to simulate the acceleration impact test of the battery pack. The energy absorption assembly is arranged on a test bed to buffer a test vehicle, so that the energy absorption assembly is in contact with the test vehicle to simulate the damage condition of a battery pack in an acceleration impact test, and the test method and data for deeply researching the acceleration impact of the power battery of the electric vehicle are accumulated, so that the performance of the power battery is conveniently researched. And the reliability of the power battery under acceleration impact is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an acceleration test device and a test method. Background technique [0002] Electric vehicles use electric energy as the driving energy, and the main part where the power battery is installed is the chassis. For electric vehicles with power batteries in the chassis. Some car companies will increase the size of the battery pack in order to extend the driving range as much as possible. When an electric vehicle has a collision accident, only the body of the electric vehicle is damaged, but the power battery has no obvious external damage, but the internal damage of the power battery cannot be judged. [0003] If the interior of the power battery is damaged, it will affect the performance of the power battery and cause potential safety hazards in electric vehicles. Therefore, it is necessary to study the impact of acceleration shock on the performance of the power batte...
