Abstract

An energy charging / discharging control apparatus of a regenerative braking apparatus of an electric vehicle and a method thereof are provided to improve electrical energy storage efficiency between a battery and a super capacitor, thereby increasing driving distance of the electric vehicle. Constitution A battery(110) is connected to both ends of an inverter(170). An auxiliary charging part(120) is connected to one or more super capacitors in series. A bidirectional converter(130) is connected between the battery and the auxiliary charging part. A current detector detects a charging / discharging current flowing between the battery and the bidirectional converter. A speed detector detects the speed of an electric vehicle.

Description

technical field [0001] The present invention relates to an energy charging and discharging control device and method for an electric vehicle regenerative braking device, in particular to an energy charging for an electric vehicle regenerative braking device capable of charging and discharging by applying a bidirectional converter between a battery and a supercapacitor And discharge control device and method. Background technique [0002] Generally, electric vehicles such as electric motorcycles, electric bicycles, and electric cars are formed so that they can drive a motor (motor), that is, an electric motor, by using electric power from a battery, and operate the electric motor as a generator when braking, so that The energy is dissipated as heat in a resistor or can be recharged with a battery. [0003] However, in the case of using a battery to store electrical energy, according to the charging and discharging characteristics of the battery, the regenerative power genera...
