Abstract

The present invention relates to a charging device and an electric vehicle equipped with the charging device. The charging device according to the present invention includes: a motor; an additional coil wound on a stator of a certain phase of the motor; a switch unit connected to the additional coil and configured to supply input power to the motor through a switching operation. The frequency converter, in the motor working mode, uses the switching action of the three-phase switching element to convert the DC power from the battery into an AC power to drive the motor, and in the charging mode, uses the switching action of the switching part , converting the input power supplied to the motor into a DC power output; the control unit, in the charging mode, controls the additional coil to cooperate with the switch unit. Thereby, charging can be easily performed by an AC power supply.

Description

technical field [0001] The present invention relates to a charging device and an electric vehicle equipped with the charging device, and more specifically, to a charging device capable of easily performing charging using an AC power source, and an electric vehicle equipped with the charging device. Background technique [0002] The automobile that appeared with the invention of the internal combustion engine is a necessity of human life, but it is also the main culprit of environmental pollution and causes energy depletion due to huge energy consumption. The current trend is to develop electric vehicles using electricity or hybrid vehicles combining internal combustion engines and these electric vehicles instead of vehicles powered by internal combustion engines. [0003] In addition, such electric vehicles, hybrid electric vehicles, etc. generate output power using motors, batteries, etc., and various proposals for improving output power and driving distance have been attem...
