Abstract

The invention discloses a low-temperature testing method applicable to a battery electric vehicle. The method comprises steps as follows: S1, setting the expected temperature of an environment bin ina low-temperature test of a battery pack in advance; S2, dismounting the battery pack of the battery electric vehicle and putting the battery pack in the environment bin for freeze cooling; S3, detecting whether the inside temperature of the battery pack in the environment bin reaches the expected temperature, if yes, taking out the battery pack, executing S4, and otherwise, continuously performing freeze cooling on the battery pack; S4, assembling the taken-out battery pack on the whole vehicle for a test on an actual road. All that is required is to freeze the battery pack, and therefore, the cost consumption is relatively low; during testing, testing is performed on peripheral roads of a factory instead of specific locations in the Northeast or Inner Mongolia, labor, transportation costand other related costs are saved, worker coordination and support response speeds are higher, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a low-temperature test method suitable for pure electric vehicles. Background technique [0002] At present, the low temperature test of outdoor pure electric vehicles is greatly affected by environmental factors, and the data of the required temperature range cannot be perfectly tested, and the cost of personnel errors and test support is very high. Contents of the invention [0003] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a low-temperature test method suitable for pure electric vehicles, which can overcome the above-mentioned shortcomings of the prior art. [0004] For realizing above-mentioned technical purpose, technical scheme of the present invention is realized like this: [0005] A low temperature test method suitable for pure electric vehicles, comprising the steps of: [0006] S1: Set the expected...
