Abstract

The invention relates to a side column impact test device and test method. The side column impact test device comprises a test bench; a test assembly which comprises a test vehicle and a mounting seat, wherein the test vehicle is movably arranged on the test bench, and the mounting seat is used for mounting a battery pack and is mounted on the test bench; a side column collision assembly which is arranged at the end part, facing the mounting seat, of the test vehicle, and a preset overlapping amount exists between the side column collision assembly and the battery pack in the vertical direction, wherein when the test vehicle moves along the test bench, the test vehicle can drive the side column impact assembly to contact with the battery pack in the mounting seat so as to simulate the side column impact test of the battery pack. The simulation of the side column collision test of the battery pack is realized, the test method and data for deeply researching the side column collision of the power battery of the electric vehicle are accumulated, the performance of the power battery is conveniently researched, and the reliability of the power battery during side column collision is improved.

Description

technical field [0001] The invention relates to the technical field of new electric vehicle tests, in particular to a side column impact 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 the power battery in the chassis, the possibility of damage to the power battery caused by a side column collision is very high. In order to extend the driving range as much as possible, some car companies have increased the size of the battery pack, which has made electric vehicles more dangerous when they are hit by a side pole. [0003] Traction batteries are the most expensive, heaviest and most dangerous components in electric vehicles. Damage to the power battery will require a higher cost whether it is repaired or replaced. Moreover, when the power battery is punctured due to a side column impact, the power battery...
