Charger for electric vehicles
First Claim
1. A charger for electric vehicles, the charger comprising:
- a first connector configured to be connected to a socket of a mains electricity power source;
a second connector configured to be connected to a device to be charged;
a charger body configured to be disposed between the first connector and the second connector and configured to control the flow of the mains electricity supplied from the first connector,wherein the charger body comprises;
an internal line resistor configured to be disposed between a wall outlet and the first connector, one end of the internal line resistor configured to be connected to the wall outlet and the other end of the internal line resistor configured to be connected to the first connector;
a switch, one end of the switch configured to be connected to the first connector and the other end of the switch configured to be connected to one end of the internal line resistor;
relays, one end of each of the relays configured to be connected to the first connector and the switch and the other end of each of the relays configured to be connected to the second connector;
a controller configured to control the switch and the relays based at least on a predetermined operation mode;
mains electricity line resistors disposed on an internal line of the mains electricity power source; and
contact resistors disposed in the first connector and in contact with the socket,wherein an overall line resistance is determined by the mains electricity lines resistors, the contact resistors and the internal line resistor.
