Problems solved by technology

[0004] For this reason, the first object of the present invention is to propose a charging control method to avoid waking up the vehicle when charging is not needed and stop charging when the low-voltage battery is not fully charged, effectively protecting the vehicle system and components. Safety, used to solve the existing problem that when the low-voltage battery is in a state of power loss, the vehicle controller of the electric vehicle may not work normally, which in turn affects the use of the electric vehicle

Abstract

The invention provides a charging control method and system, wherein the method includes: when a vehicle is in hibernation mode, detecting whether a low-voltage battery is in undervoltage or not; if yes, acquiring state information of the vehicle; judging whether charging the low-voltage battery through a power battery is available according to the state information; if yes, using the power battery to charge the low-voltage battery. By using the method, it is avoided that charging is stopped due to vehicle wakeup in case of no need for charging and in case of the low-voltage battery being not fully charged; vehicle system and parts safety is effectively protected.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a charging control method and system. Background technique [0002] With the continuous development of electric vehicles and vehicle engineering, electric vehicles are equipped with more and more electronic and electrical components, resulting in a larger static power consumption of electric vehicles than traditional vehicles. When the electric vehicle is not used for a long time, it may cause the low-voltage battery to lose power. When the low-voltage battery is in a power-deficit state, it may cause the vehicle controller of the electric vehicle to fail to work normally, thereby affecting the use of the electric vehicle. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first object of the present invention is to propose a charging control meth...
