Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a fault handling method, device, central control system and electric vehicles for electric vehicles. Background technique [0002] With the continuous development of automobile technology, new energy vehicles mainly driven by motors have been accepted by more and more people, which has also led to the rapid development of the electric vehicle industry. With the development of electric vehicles, the drive of electric vehicles has gradually developed from the previous single-motor drive to multi-motor drive. The development of single-motor drive to multi-motor drive is also accompanied by the increase of drive components, which makes the probability of failure of electric vehicles higher and higher, and the requirements for troubleshooting of electric vehicles are also higher and higher. [0003] The traditional fault handling technology of electric vehicles us...
