Electric vehicle nondestructive charging system based on temperature curve and charging method of electric vehicle nondestructive charging system based on temperature curve

The invention discloses an electric vehicle nondestructive charging system based on a temperature curve and a charging method of the electric vehicle nondestructive charging system based on the temperature curve. The electric vehicle nondestructive charging system comprises a power conversion unit, a power factor correction unit, a driving unit, a protection and logic control unit, a master control unit, a man-machine interaction interface, a communication interface and a storage device. The power conversion unit is mainly used for completing AC/DC and DC/DC conversion. The power factor correction unit is used for completing input side power factor correction and achieving a unit power factor. The driving unit is mainly used for achieving generation of driving pulses. The protection and logic control unit is used for controlling signal output and signal blocking of the driving unit to achieve fault output control and indicating. The master control unit is used for achieving key algorithms and the like. The communication interface is used for communication of an electric vehicle power battery management system. The man-machine interaction interface is used for charging information displaying and user charging setting. According to the electric vehicle nondestructive charging system and the charging method, the service life of a battery and rapid charging are guaranteed, and meanwhile nondestructive rapid charging in the true sense is achieved.
