Abstract:
PURPOSE: A method for controlling the current collection of an electric vehicle is provided to improve the performance and reliability of the electric vehicle by distributing battery charging power and feeding power based on the demand power of the electric vehicle. CONSTITUTION: Demand energy is calculated according to the supply power of an electric vehicle through a MCU. If the demand power is high power or more(S50), the collected induced magnetism energy is supplied as the demand energy of the driving motor(S70). If the demand power is between low power and high power, a part of the collected induced magnetism energy is supplied as the demand energy of the driving motor(S60). The remaining induced magnetism energy is classified into the surplus energy(S80). The classified surplus energy is charged based on SOC(State Of Charge) of a battery(S130).

PURPOSE: A method for controlling a charged power distribution of an electric vehicle of a noncontact electromagnetic inductive charging method is provided to prevent overcharge current inputted to a battery by controlling energy which is inputted from both sides of a regulator and a regenerative breaking side to the battery. CONSTITUTION: It is determined whether regenerative braking power is currently supplied(S202). A regulator is off if the regenerative braking power is currently supplied(S203). A battery is charged with the regenerative braking power(S204). The regulator is on if the regenerative braking power is not supplied(S205). The battery is charged by supplying power from the regulator(S206,S207).
