1. A method for controlling plural chargers equipped in a vehicle, comprising:
- recognizing a plurality of chargers, each configured to charge at least one battery supplying the vehicle with electric power, via an in-vehicle network;
receiving an identification and at least one parameter from each recognized charger, which are delivered via the in-vehicle network;
recognizing the identification of each recognized charger through communication between a charging controller and each recognized charger;
generating plural instructions, each instruction for each recognized charger in response to receiving the identification and the at least one parameter; and
delivering the plural instructions to the plurality of recognized chargers via the in-vehicle network, whereinwhen the plurality of chargers are recognized, a connection broadcast message is transmitted to each recognized charger,the identification and the at least one parameter is received from a charger having received the connection broadcast message, andthe recognizing of the identification of each recognized charger comprises;
measuring voltage levels at both sides of a resistor of each recognized charger to calculate a resistance corresponding to each recognized charger, andmatching each recognized charger with the resistance corresponding to each recognized charger to recognize the identification of each recognized charger.
