Method, charging-discharging device, cloud server, system and medium for charging-discharging interaction

1. A method for charging-discharging interaction, comprising:

transmitting, by a charging-discharging device, a vehicle-to-grid (V2G) function confirmation message to a battery management system of a target vehicle;

transmitting, by the charging-discharging device, a first indication message to a cloud server to indicate that the target vehicle is V2G-disabled, when no V2G function feedback message fed back by the battery management system is received within a preset period of time after transmitting the V2G function confirmation message;

performing, by the charging-discharging device, a non-V2G charging for the target vehicle, in response to a non-V2G charging instruction received from the cloud server,

wherein the non-V2G charging instruction is transmitted by the cloud server in response to the first indication message or a non-V2G charging mode selection instruction from a terminal device communicatively connected with the cloud server.

2. The method for charging-discharging interaction according to claim 1 , wherein before the transmitting by a charging-discharging device, a V2G function confirmation message to a battery management system of a target vehicle, the method further comprises:

transmitting, by the charging-discharging device, a wake-up signal to the battery management system to wake up the battery management system.

3. The method for charging-discharging interaction according to claim 1 , wherein after the transmitting, by a charging-discharging device, a V2G function confirmation message to a battery management system of a target vehicle, the method further comprises:

transmitting, by the charging-discharging device, a second indication message to the cloud server to indicate that the target vehicle is V2G-enabled, when a V2G function feedback message fed back by the battery management system is received within the preset period of time after transmitting the V2G function confirmation message;

performing, by the charging-discharging device, a V2G charging or V2G discharging for the target vehicle, in response to a received grid scheduling instruction.

4. A charging-discharging device, comprising:

a processor; and

a memory storing computer program instructions,

wherein the processor, when executing the computer program instructions, implements the method for charging-discharging interaction according to claim 1 .

5. A method for charging-discharging interaction, comprising:

receiving, by a cloud server, a first indication message from a charging-discharging device, wherein the first indication message is transmitted by the charging-discharging device when no V2G function feedback message is received within a preset period of time after transmitting a V2G function confirmation message to a battery management system of a target vehicle, and the first indication message is to indicate that the target vehicle is V2G-disabled;

transmitting, by the cloud server, a non-V2G charging instruction to the charging-discharging device, to instruct the charging-discharging device to perform a non-V2G charging for the target vehicle,

wherein the transmitting, by the cloud server, a non-V2G charging instruction to the charging-discharging device comprises:

transmitting, by the cloud server, the non-V2G charging instruction to the charging-discharging device, in response to the first indication message or a non-V2G charging mode selection instruction from a terminal device communicatively connected with the cloud server.

6. The method for charging-discharging interaction according to claim 5 , wherein before the transmitting, by the cloud server, a non-V2G charging instruction to the charging-discharging device, the method further comprises:

transmitting, by the cloud server, a third indication message to the terminal device, to indicate that the target vehicle is V2G-disabled;

receiving, by the cloud server, the non-V2G charging mode selection instruction from the terminal device.

7. The method for charging-discharging interaction according to claim 5 , further comprising:

receiving, by the cloud server, a second indication message from the charging-discharging device, wherein the second indication message is transmitted by the charging-discharging device when a V2G function feedback message is received within the preset period of time after transmitting the V2G function confirmation message to the battery management system of the target vehicle, and the second indication message is to indicate that the target vehicle is V2G-enabled;

transmitting, by the cloud server, a fourth indication message to a terminal device in response to the second indication message, to indicate that the target vehicle is V2G-enabled, wherein the terminal device is communicatively connected with the cloud server.

8. A cloud server, comprising:

a processor; and

a memory storing computer program instructions,

wherein the processor, when executing the computer program instructions, implements the method for charging-discharging interaction according to claim 5 .

9. A non-transitory computer-readable storage medium, having computer program instructions stored thereon, which, when executed by a processor, implement the method for charging-discharging interaction according to claim 5 .
