Example Embodiment

[0052] Example one

[0053] The embodiment of the present invention provides a charging control method, see figure 1 , The method includes:

[0054] Step 101: The on-board terminal of the electric vehicle receives a charging control command. The charging control command includes a charging stop command, a discharging command, or a preset power charging control command. The charging control command is generated according to the grid load condition.

[0055] Step 102: Determine whether the charge control command is allowed to be executed according to the set charge and discharge conditions.

[0056] Step 103: When the charging control command includes a charging stop control command, and the charging and discharging conditions indicate that charging is allowed to be stopped, control the charging and discharging machine of the electric vehicle to stop charging the on-board power supply of the electric vehicle;

[0057] When the charging control command includes a charging command at a pres...

Example Embodiment

[0060] Example two

[0061] The embodiment of the present invention provides a charging control method, see figure 2 , The method includes:

[0062] Step 201: The on-board terminal of the electric vehicle receives a charging control command. The charging control command includes a charging stop command, a discharging command, or a preset power charging control command. The charging control command is generated according to the grid load condition.

[0063] Specifically, the on-board terminal of the electric vehicle may receive a charging control instruction through (General Packet Radio Service, general packet radio service technology).

[0064] The charging control command can be generated according to the following methods: when the charging control system detects that the grid load is large (for example, exceeding a set threshold), it can generate a preset power charging control command or a stop charging control command to restrict the electric vehicle from being Set power chargi...

Example Embodiment

[0099] Example three

[0100] The embodiment of the present invention provides a charging control method, see image 3 , The method includes:

[0101] Step 301: The charging control system obtains the grid load status.

[0102] Step 302: Generate a charging control command according to the grid load condition. The charging control command includes a charging stop command, a discharging command, or a preset power charging control command.

[0103] For example, the charging control system can generate a charging control command according to the following method: when the charging control system detects that the grid load is large (for example, exceeding a set threshold), it can generate a charging control command at a preset power or a charging stop control command to Restrict electric vehicles from charging at a preset power or control electric vehicles to stop charging. After a period of time, if stopping charging can not meet the power demand of the grid (for example, the load is st...

Abstract

The invention discloses a charge control method, an electric car car-mounted terminal and a charge control system, and belongs to the field of electric cars. The method comprises the steps that charge control instructions are received, the charge control instructions comprise a charge stopping control instruction and a preset-power-based charge instruction or a discharge instruction; whether the charge control instructions are allowed to be executed according to set charge-discharge conditions; when the charge control instructions comprise the charge stopping control instruction and charge stopping is allowed according to the charge-discharge conditions, a charge-discharge machine of an electric car is controlled to be stopped to charge a car-mounted power supply of the electric car; when the charge control instructions comprise the preset-power-based charge instruction and charging according to preset power is allowed according to the charge-discharge conditions, the charge-discharge machine of the electric car is controlled to charge the car-mounted power supply of the electric car; when the charge control instructions comprise the discharge instruction and discharging is allowed according to the charge-discharge conditions, the charge-discharge machine is controlled to carry out discharging to a power grid. Electric car intelligent charging is achieved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a charging control method, an electric vehicle vehicle terminal and a charging control system. Background technique [0002] An electric vehicle refers to a vehicle that uses an on-board power supply to provide power to the motor to drive the wheels. [0003] The biggest difference between electric vehicles and ordinary vehicles is that gasoline and engines are replaced by on-board power supplies and motors, which are energy-saving and environmentally friendly. At the same time, when the power of the on-board power supply is low, it only needs to be charged in a parking lot equipped with a charging device. Compared with ordinary cars that have to go to a gas station when they are out of gas, it is more convenient, faster, and cheaper. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: ...
