Electric vehicle charging auxiliary system and application thereof

Abstract

The invention discloses an electric vehicle charging auxiliary system comprising an auxiliary system controller, input and output equipment, a charging socket, a first voltage sensor, a multipath controllable switch and a sound-light alarm system, wherein the first voltage sensor, the multipath controllable switch, the input and output equipment and the sound-light alarm system are respectively connected with the auxiliary system controller. The auxiliary system controller and its memory are internally provided with charging auxiliary monitoring software and connected with a power supply management system controller. The charging socket connects an external power supply to a power battery pack through the multipath controllable switch, a rectifying and filtering circuit and a current sensor. The first voltage sensor monitors accessing of the external power supply of the charging socket. The current sensor monitors current of the power batteries. A second voltage sensor monitors voltage of the power battery pack. The sound-light alarm system is used for providing charging sound-light alarm. An electric vehicle using the electric vehicle charging auxiliary system is suitable for more charging power supplies so that arrangement is convenient and charging safety is high.

Description

technical field [0001] The invention relates to an electric vehicle charging auxiliary system and its application. Background technique [0002] The number of electric vehicles manufactured and used in my country has shown a rapid growth trend, which has improved the problem of air and noise pollution in cities to a certain extent. But because this type of vehicle must use electric energy, for this reason, its battery must be charged by the outside. [0003] With the increase in the number of electric vehicles used, problems such as electric vehicle charging safety, charging efficiency, and charging convenience have become increasingly prominent, seriously affecting the use and large-scale promotion of electric vehicles, and also affecting the improvement of the urban environment. Therefore, how to improve the adaptability of electric vehicles to charging power sources, so that electric vehicles can be applied to more charging power sources, and thus improve convenience, ha...
