Problems solved by technology

[0002] At present, the development process of automobiles generally has to go through three high tests (high temperature, high cold, and plateau). For pure electric vehicles, the high temperature test mainly verifies the battery pack; It needs to be tested in a suitable season. This traditional method has the disadvantages of long cycle, high cost and high cost.

Abstract

The invention discloses an alternative method for a summer test of a pure electric vehicle. The method comprises a step of carrying out heat insulation on a battery pack, a step of heating the batterypack in a test chamber to a certain temperature, a step of installing a heated battery pack on a vehicle chassis, connecting all high and low voltage electrical appliances such that a vehicle satisfies a normal driving state, and a step of finally carrying out a summer extreme environmental test on the vehicle. The method has the advantages that the method is less limited by a region or season, the cost is low, the test period is short, so the test is very flexible to implement, since the test implementation is flexible, the test time and the test content can be increased, and thereby the purpose of shortening the development cycle of the electric vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for replacing a summer test of a pure electric vehicle. Background technique [0002] At present, the development process of automobiles generally has to go through three high tests (high temperature, high cold, and plateau). For pure electric vehicles, the high temperature test mainly verifies the battery pack; It needs to be tested in a suitable season. This traditional method has the disadvantages of long cycle, high cost and large expense. Contents of the invention [0003] Aiming at the above-mentioned technical problems in the related art, the present invention proposes an alternative method for the summer test of pure electric vehicles, which can overcome the above-mentioned deficiencies in the prior art. [0004] For realizing above-mentioned technical purpose, technical scheme of the present invention is realized like this: [0005] An alternativ...
