Description
technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a device and method for realizing AC fast charging of a power battery through a motor controller. Background technique [0002] With the development of related technologies, electric vehicles have gradually entered the work and life of the public, and in the related technologies of electric vehicles, the batteries of electric vehicles as energy providers are very important. The lightweight of electric vehicles is an important topic of research at this stage. The existing technology is to form a battery charging circuit through the OBC on-board charging unit and the MCU motor controller. Since the OBC on-board charging unit, that is, the on-board charger and the power battery need to be connected through a high-voltage wiring harness, In addition, the on-board charger needs to be connected to the cooling pipeline for cooling. In vehicles such as plug-in hybrid ve...
