Abstract

The invention discloses an electric automobile AC-DC-combined charging control system. An electric automobile charging control circuit comprises a switch unit connected in series between a power supply system and an electric automobile inner battery packet; a voltage detection module used for detecting power supplying voltage at a connection point of a charging system and the battery packet in real time; and a microprocessor used for adjusting the output voltage of the charging system when it is determined that the power supplying voltage exceeds a preset voltage threshold value range in order to enable the power supplying voltage within the preset voltage threshold value range. Compared with a product in the prior art, the electric automobile charging control circuit monitors the power supplying voltage from the charging system to the electric automobile inner battery packet in real time and adjusts the power supplying voltage within the preset voltage threshold value range of the battery packet such that the power supplying voltage of the battery packet automatically satisfies a charging requirement of the electric automobile and the charging efficiency of the electric automobile is increased. Additionally, the charging security of the electric automobile inner battery packet is effectively protected and the electric automobile AC-DC-combined charging control system has significant market meaning.
