US 2025/0153607 A1 · IEC 61851-1 STANDARD REGARDING GRID CODE REQUIREMENTS AND SETPOINT TO LIMIT BATTERY DISCHARGE

Abstract

The described technology is generally directed towards implementation of an electric vehicle (EV) as an energy generator for a vehicle to grid (V2G) power discharge operation. Energy available at a battery onboard the EV can be discharged to an electrical grid operated by a distribution system operator (DSO), e.g., via an electric vehicle supply equipment (EVSE)/wallbox. A parameter can be received at the EV, comprising one of a setpoint (e.g., defining a value to be complied with during the BPT operation) or a limit (e.g., defining a value or level that cannot be exceeded during the V2G operation). The discharge operation at the EV can be controlled/adjusted in accordance with the parameter. The parameter can be received in a digital signal, and the EVSE complies with IEC 61851. The parameter complies with a grid code implemented at the EVSE, the grid code complies with EN 50549.

Claims20

Dependent claims

A system, located on an electric vehicle (EV), comprising:

at least one processor;
and
a memory coupled to the at least one processor and having instructions stored thereon, wherein, in response to the at least one processor executing the instructions, the instructions facilitate performance of operations, comprising:
receiving, in a communication, a parameter, wherein the parameter comprises one of a setpoint or a limit;
and adjusting operation of the EV in accordance with the parameter, wherein the operation is a bidirectional power transfer (BPT) operation.

2 more elements

A computer program product stored on a non-transitory computer-readable medium and comprising machine-executable instructions, wherein, in response to being executed, the machine-executable instructions cause a system located on an electric vehicle (EV) to perform operations, comprising:

receiving a parameter, wherein the parameter comprises one of a setpoint or a limit setting, and the device is located onboard an electric vehicle (EV), wherein the parameter is received via an electric vehicle supply equipment (EVSE), wherein the EVSE is configured to be in compliance with IEC 61851-1;
and
adjusting operation of the EV in accordance with the parameter, wherein the operation comprises discharging electrical energy from a battery located onboard the EV to an electrical grid.
