Abstract

The invention belongs to the technical field of charge of new energy automobiles, and relates to an electromobile quick charge method. The method comprises the following steps that: a vehicle control unit receives a quick charge wake-up signal sent by a quick charge pile and controls the whole vehicle to be charged; a battery management system enters a charge response stage; in the charge response stage, through the response information interaction with the quick charge pile, the charge response is ensured to be normal, and the battery management system enters a charge parameter configuration stage; in the charge parameter configuration stage, through parameter information interaction with the quick charge pile, the charge parameter configuration is ensured to be normal, and the battery management system enters the charge stage; in the charge stage, through charge information interaction with the quick charge pile, the charge process is ensured to be normal, and the battery management system enters the last charge stage; and in the last charge stage, the battery management system confirms the charge completion or charge failure by the last information interaction with the quick charge pile. By the electromobile quick charge method, the quick charge process is in an efficient and safe state.

Description

technical field [0001] The invention belongs to the technical field of charging new energy vehicles, and relates to a fast charging method for electric vehicles. Background technique [0002] With the development of automobile energy towards new energy, electric vehicles have gradually become an important direction for the development of automobile technology. In electric vehicles, the energy source of the automobile mainly comes from the external charging of the vehicle, through the external charging of the battery pack of the whole vehicle, In order to realize the function of injecting energy into the vehicle, with the user's requirements for the charging speed of the vehicle, the fast charging solution has gradually become an important content of electric vehicle charging. [0003] Such as figure 1 As shown, it is a schematic diagram of the connection between the fast charging pile and the battery pack. When the fast charging pile is connected to the vehicle, the fast ch...
