Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] In a first aspect, an embodiment of the present invention provides a battery replenishment method.

[0051] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the battery replenishment method of the present invention. Such as figure 1 As shown, in one embodiment, the battery replenishment method includes:

[0052] Step S10, when the telematics processor T-BOX detects that the SOC value of the battery is less than the first preset value, and the time difference between the current time and the time when the power replenishment request was initiated last time is greater than the preset time difference, send a power replenishment request To the vehicle controller VCU;

[0053] In this embodiment, the telematics processor T-BOX acquires the SOC value of the battery through the battery...

Abstract

The invention provides a storage battery charging method and system and a readable storage medium. The method comprises the steps that when TBOX detects that the SOC value of a storage battery is smaller than a first preset value and the time difference between the current moment and the moment when a charging request is initiated last time is larger than a preset time difference, the charging request is sent to a VCU; when receiving the charging request, the VCU detects whether a charging condition is met; when the charging condition is met, the VCU controls the high-voltage power battery tocharge the storage battery and feeds back charging start state information to the T-BOX; in the charging process, the VCU detects whether a charging quitting condition is met; and when the charging quitting condition is met, the VCU controls the high-voltage power battery to stop charging the storage battery and feeds back charging quitting state information to the T-BOX. According to the storagebattery charging method, when the charging condition is met, the storage battery is charged, and when the charging quitting condition is met, the charging of the storage battery is stopped, so that the flexible control of the charging of the storage battery is realized, and the situation of feeding of the storage battery is avoided as much as possible.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a storage battery replenishment method, system and readable storage medium. Background technique [0002] Because the adverse impact of electric vehicles on the environment is relatively small compared with traditional fuel vehicles, its prospects are widely optimistic. [0003] The power energy of an electric vehicle comes from the battery, but when the vehicle is parked for a long time, the battery will feed power, which will cause the vehicle to fail to start. Therefore, there is an urgent need for a solution to recharge the battery to avoid the situation that the vehicle cannot be started due to battery power feeding. Contents of the invention [0004] In order to achieve the above purpose, the present application provides a battery replenishment method, system and readable storage medium. [0005] In a first aspect, the present invention provides a battery replenishment ...
