Vehicle-mounted low-voltage storage battery remote charging method and system

Abstract

The invention discloses a vehicle-mounted low-voltage storage battery remote charging method and system. The residual electric quantity of a battery is detected through a battery management unit, andthe residual electric quantity is actively reported to a user unit through a remote control unit when the electric quantity is lower than a threshold value. A remote control unit controls a high-voltage charging unit to charge the battery and sends the remote charging state information to the user unit through the remote control unit only when the remote control unit receives the starting confirmation information fed back by the user, and the voltage information of a battery end and the charging information of a charging end are monitored at the same time in the charging process. According tothe present invention, the charging state in the charging process is comprehensively monitored, after it is detected that charging of the battery is completed, the high-voltage charging unit stops charging the battery, and the remote control unit sends the charging completion information to the user unit, so that the problem that the remote control and operation experience of the user are affecteddue to the fact that an existing vehicle-mounted battery charging management method cannot actively and comprehensively upload the battery related information, is solved.

Description

technical field [0001] The invention relates to the field of on-vehicle battery charging, in particular to a remote charging method and system for an on-vehicle low-voltage storage battery. Background technique [0002] For new energy vehicles, due to the continuous increase of electrical devices and power consumption, and the complex interaction logic between controllers and complex power management, it is impossible to accurately monitor and control the power consumption of each controller, often due to abnormal operations by users 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 increasing popularity of new energy vehicles, there are many charging management methods for on-board batteries. However, the current on-board battery charging management requires the user to actively inquire about the vehicle's condition. After finding that the vehicle voltage is abnormal, the local or remote cont...
