Abstract
A method is provided for detecting a state of a connection between an electrically driven motor vehicle (1) and a corresponding charging station. The motor vehicle (1) has a control pilot (CP) function with a vehicle-side control pilot (CP) line (3). The method includes using a power line communication (PLC) chip (2) of the motor vehicle (1) to measure the length of a control pilot line between the motor vehicle and the charging station.
Claims9
A method for detecting a state of a connection between a charging station and an electrically driven motor vehicle that has a power line communication chip and a vehicle-side control pilot line, the method comprising:
- plugging a power line of the charging station into the motor vehicle to connect the vehicle-side control pilot line to a control pilot line of the charging station;
- and using the power line communication chip of the motor vehicle to measure a length of the control pilot line between the motor vehicle and the charging station.
A method for detecting a state of a connection between a charging station and an electrically driven motor vehicle that has a power line communication chip and a vehicle-side control pilot line, the method comprising:
- plugging a power line of the charging station into a socket of the motor vehicle;
- sensing the presence or absence of current being delivered from the charging station to the motor vehicle;
- using the power line communication chip of the motor vehicle to measure a length of the control pilot line from power line communication chip of the motor vehicle toward the charging station;
- comparing the length of the control pilot line from power line communication chip of the motor vehicle toward the charging station to a known length of the control pilot line from power line communication chip of the motor vehicle to the socket;
- and
- identifying a class of cable at the charging station based on the length of the control pilot line from power line communication chip of the motor vehicle toward the charging station and the sensed presence or absence of current being delivered from the charging station to the motor vehicle.
An electrically driven motor vehicle, comprising:
- a socket for accommodating a plugged connection with a power line of a charging station;
- a power line communication chip and a vehicle-side control pilot line extending from the power line communication chip to the socket, wherein the power line communication chip has a control pilot means for measuring a length of the control pilot line between the motor vehicle and the charging station.
