A method and system for remote charging of vehicle low-voltage battery

Abstract

The invention discloses a remote charging method and system for a low-voltage battery in a vehicle. The battery management unit detects the remaining power of the battery, and when the power is lower than a threshold, the remote control unit actively reports to the user unit. The high-voltage charging unit is controlled to charge the battery only when the feedback confirms the information is turned on, and the remote charging status information is sent to the user unit through the remote control unit. During the charging process, the voltage information of the battery terminal and the charging information of the charging terminal are monitored at the same time, and the charging is fully monitored. The charging state in the process, after detecting that the battery is charged, the high-voltage charging unit stops charging the battery, and the remote control unit sends the charging completion information to the user unit. It solves the problem that the current vehicle battery charging management method cannot actively and comprehensively upload battery-related information, which affects the user's remote control and operation experience.

Description

technical field [0001] The invention relates to the field of vehicle battery charging, in particular to a remote charging method and system for a vehicle low-voltage battery. Background technique [0002] For new energy vehicles, due to the continuous increase of electrical devices, the increase of power consumption, the complex interaction logic between controllers, and the complex power management, the power consumption of each controller cannot be accurately monitored and controlled, often due to abnormal user operations or other reasons. This will cause the vehicle to lose power and affect the normal use of the vehicle by the user. In the face of the increasingly popular new energy vehicles, there are many charging management methods for on-board batteries. However, the current vehicle battery charging management requires the user to actively query the vehicle status. After finding the vehicle voltage abnormality, the local or remote control starts the engine or prepare...
