Electric vehicle charging control system capable of setting charging capacity and charging setting device

Abstract

The invention provides an electric vehicle charging control system capable of setting charging capacity, which comprises a controller, a setting unit, a battery unit and an instrument unit, the battery unit comprises a battery core group for providing electric power for an electric vehicle, the setting unit is arranged on the electric vehicle and is connected with the controller, and the instrument unit is connected with the controller. The controller is used for a user to input a charging interval setting instruction so as to set a charging interval of the battery core group, and the instrument unit is connected with the controller so as to display charging information of the electric vehicle; according to the invention, a user can set the charging interval of the battery core group according to requirements, when the charging interval range is large, the electric vehicle can have preferable endurance, and when the charging interval range is large, the battery core group of the electric vehicle has long service life.

Description

technical field [0001] The present invention relates to a charging control system for an electric vehicle, in particular to a charging control system that allows users to set charging capacity by themselves. Background technique [0002] At present, the power source of electric vehicles is mainly provided by lithium batteries. According to the different designs of vehicle models and battery structures, some batteries adopt a removable structure. Users can take out the batteries from the electric vehicle at will and charge them externally. Then put it back into the car; the other type of battery is a fixed built-in type, and it is difficult for users to disassemble the battery from the car. When charging this kind of battery, an external charger needs to be connected to the charging port of the car body , the external power is transmitted to the battery in the car through the charger. [0003] When the charger is used to charge the battery in the electric vehicle, the existi...

[0002] At present, the power source of electric vehicles is mainly provided by lithium batteries. According to the different designs of vehicle models and battery structures, some batteries adopt a removable structure. Users can take out the batteries from the electric vehicle at will and charge them externally. Then put it back into the car; the other type of battery is a fixed built-in type, and it is difficult for users to disassemble the battery from the car. When charging this kind of battery, an external charger needs to be connected to the charging port of the car body , the external power is transmitted to the battery in the car through the charger

[0003] When the charger is used to charge the battery in the electric vehicle, the existing charging control mechanism is to set a fixed charging capacity by the car manufacturer. For example, when the battery is charged from 0% to 100%, its voltage changes from a first voltage The value V1 is fully charged to a second voltage value V2, and the range of this charging range remains fixed, and the user cannot decide the full charging voltage by himself.

[0004] The fixed charging range limits the power that the battery can store, and naturally limits the range of electric vehicles

If the user expects to travel a long distance, the battery must be charged more frequently, which is very inconvenient for the user
