Commercial vehicle power generation device and control method based on bsg motor

Abstract

The invention relates to a commercial vehicle power generation device based on a BSG motor and a control method thereof; the power generation device includes a BSG motor, a pre-charged DCDC, an upper battery pack, a battery management module, a power generation device controller and a relay; the driving end of the BSG motor and The engine connection of the commercial vehicle, the busbar of the BSG motor is connected to the power terminal of the battery management module through the contact of the relay, the output terminal of the pre-charged DCDC is connected to the busbar of the BSG motor, the power terminal of the battery management module is connected to the bodywork equipment, and the power generation device The controller controls the operation of each device; the control method first judges whether the commercial vehicle is in the driving or parking state, and whether the upper-mounted battery pack is allowed to be charged; then requests the power generation torque of the BSG motor when parking and driving according to the situation; finally monitors the BSG Charging of the motor. The invention improves the power generation efficiency and the reliability of the whole vehicle, and optimizes and improves the vehicle performance and emission in the power generation process.

Description

technical field [0001] The invention relates to an automobile power generation device and a control method thereof, in particular to a commercial vehicle power generation device based on a BSG motor and a control method thereof. Background technique [0002] With the development of time, the demand for commercial vehicle modification has become more and more diverse. The number of electrical equipment installed on the body has increased, and the demand for electrical power has increased (such as: RV modification, ambulance modification, etc.), all of which put forward higher power supply requirements for the basic chassis of commercial vehicles. [0003] First of all, traditional commercial vehicle modification is to use the 12V generator on the basic chassis to supply power to the upper battery pack and equipment. The 12V generator needs to meet the power supply requirements of the 12V low-voltage system of the base vehicle and the battery pack and equipment on the body. T...
