[0034] see figure 1 , an embodiment of the present invention provides a vehicle charging control system, including: a monitoring system, a vehicle controller, a battery controller and a vehicle charger;
[0035] Wherein, the monitoring system is used to output a first wake-up signal to the vehicle controller when it is detected that the vehicle power supply is turned off and the vehicle battery is in a non-charging state for more than a preset time.
[0036] Optionally, the monitoring system is in a dormant state when the vehicle power is turned off and the vehicle battery is in a non-charging state. In the dormant state, the monitoring system internally counts. When a preset time is exceeded, the monitoring system starts automatically and outputs to the vehicle controller. The first wake-up signal wakes up the vehicle controller. Wherein, the preset time can be set to 48 hours.
[0037] The vehicle controller receives the first wake-up signal and forwards the first wake-up ...

[0051] see figure 2 , the second embodiment of the present invention provides a vehicle charging control method, applied to the vehicle charging control system in the first embodiment, the method includes:
[0052] Step 201, when it is detected that the vehicle power is off and the vehicle battery is in the non-charging state for more than a preset time, obtain the first state of charge of the vehicle battery, the first state of charge is the state of charge of the vehicle battery in the non-charging state.
[0053] Optionally, when it is detected that the power supply of the car is turned off and the car battery is in a non-charging state for more than a preset time, the first state of charge of the car battery is obtained. The ratio of the remaining capacity after long-term storage to the capacity of the fully charged state, usually expressed as a percentage. Wherein, the preset time can be set to 48 hours.
[0054] Step 202, outputting a first charging signal and a first...

Abstract
The invention provides an automobile charging control system and an automobile charging control method. The automobile charging control system comprises a monitoring system, a vehicle controller, a battery controller and a vehicle-mounted charger, wherein the monitoring system is used for outputting a first awakening signal to the vehicle controller when the situations that an automobile power source is closed and the duration that an automobile battery is under a non-charging state exceeds a preset time are detected; the vehicle controller receives the first awakening signal, transmits the received first awakening signal to the battery controller, receives the charged state of the automobile battery reported by the battery controller, and when a first charged state of the automobile battery is lower than a first preset value, outputs a first charging signal to the vehicle-mounted charger and outputs a first monitoring command to the battery controller; and the vehicle-mounted charger receives the first charging signal, and controls the automobile battery to charge according to the first charging signal. According to the automobile charging control system and the automobile charging control method disclosed by the invention, the problem that the normal using of the automobile is influenced by the self-discharge of a power battery of an electric automobile is solved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile charging control system and an automobile charging control method. Background technique [0002] As the pressure on resources and the environment continues to increase, new energy vehicles represented by electric vehicles have become an important direction for the development of the automobile industry. Electric vehicles have gradually opened up the market and entered people's lives. The power battery of an electric vehicle has self-discharge characteristics. Self-discharge, also known as charge retention capacity, refers to the ability to maintain the power stored in the power battery under certain environmental conditions in an open circuit state. Generally speaking, self-discharge is mainly affected by manufacturing process, materials, and storage conditions; the monthly self-discharge rate of lithium-ion batteries of general manufacturers is 6%-8%, however, ...
