Abstract

The invention provides a quick-change battery pack and an electric automobile, and relates to the technical field of automobiles. The quick-change battery comprises a storage battery pack module and a battery management system connected with the storage battery pack module, and the quick-change battery pack further comprises a high-voltage filtering module connected with the storage battery pack module through a high-voltage wire harness; the low-voltage filtering module is connected with the battery management system through a low-voltage wire harness; the high-voltage direct-current contactor is arranged between the high-voltage filtering module and the storage battery pack module and is connected with the battery management system; the high-voltage filtering module, the low-voltage filtering module, the storage battery pack module and the battery management system are all arranged in the storage battery pack shell. According to the quick-change battery pack provided by the embodiment of the invention, the problem of electromagnetic compatibility of part of the battery packs when the quick-change battery pack is applied is avoided, and the interference resistance of the electric vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a quick-change battery pack and an electric vehicle. Background technique [0002] As an important measure to solve users' mileage anxiety and improve customer charging experience, electric vehicle quick-change technology is being adopted by more and more car companies on public vehicles. Compared with the fixed pack, the change of the quick-change battery pack is not only structural adjustments such as fixing and charging connectors, but also the matching problem between the battery pack and the vehicle brought about by frequent battery pack replacement, especially electromagnetic compatibility. characteristic. The state consistency of electric vehicles and quick-change battery packs determines that some battery packs will exhibit poor electromagnetic compatibility on some vehicles, so that the battery management system monitors voltage fluctuations, temperature jumps, and ...
