Stand by and
The supply device is woken up by a signal from the EV.
Compatibility of the primary and the secondary devices is
checked with the information exchanged at the initialization phase: power
classes, operating frequency, magnetic coupling, circuit topology, tuning.
The MF-WPT system will determine that the primary and
secondary devices are properly well positioned relative to each other.
The MF-WPT system is capable to transfer the power from
the primary device to the secondary device upon the request from the vehicle.
The MF-WPT system does not perform power transfer until the command and control
communication is properly established and the primary device and secondary
device are properly positioned.
MF-WPT system transfers the power from the primary device
to the secondary device in accordance with the power demand of the EV. The
maximum transferring power of the off-board MF-WPT system must not be exceeded.
The vehicle can change the requested transfer power.
MF-WPT system is able to stop transfer the power from the
primary device to the secondary device in accordance with the demand of the EV.
The vehicle can requested stop power transfer.
Stop Power Transfer
MF-WPT system allows the user to terminate of power
supply. (e.g. pushing stop button).
monitoring & diagnostics
monitoring of power transfer conditions
monitoring of command & control communication
monitoring of safety conditions
Monitoring: The supply device provide means to verify that the actual
output power does not differ from the expected output power by a certain limit;
if the limit is exceeded, it shall stop power transfer.
WPT systems is capable to detect metallic objects and to stop the power
Protection: WPT systems provide life object protection by design or may
provide means to detect live objects and to stop power transfer.
The supply device stops the transfer in case of of power short-circuit,
earth leakage, excess temperature, insulation failure, overcurrent, overload
Ventilation: Verify that the ventilation system of the area is
functioning and active.
