Multifunctional electric vehicle charging station

Abstract

The invention relates to a multifunctional electric vehicle charging station which comprises vehicle type detection equipment, a Freescale MC9S12 chip and multiple charging pile bodies, wherein the vehicle type detection equipment is used for detecting the types of vehicles on the road near the charging station; each charging pile body is used for charging the electric vehicles; and the Freescale MC9S12 chip is connected with the vehicle type detection equipment and the charging pile bodies respectively and used for determining the percentage of the number of electric vehicles on the road near the charging station based on the vehicle number according to the detection result of the vehicle type detection equipment and further determining the on/off control policy on the charging pile bodies in the charging station. Through the invention, the functions of the charging station can be expanded, and excessive waste of power resource is avoided.

Description

technical field [0001] The invention relates to the field of charging stations, in particular to a multifunctional electric vehicle charging station. Background technique [0002] The charging station includes multiple charging piles, and the working principle of each charging pile is as follows: the normal (night priority) grid power is used to store and charge the regenerative battery through the primary primary side charger. Since there is no time requirement for energy storage and charging, therefore It can be charged slowly with a small current, and the charging current can automatically arrange the charging time according to the battery power, so as to maximize the use of the night-time valley power. When it is necessary to charge the electric vehicle, according to the allowable maximum charging current and voltage of the electric vehicle, the electric vehicle is quickly charged through the secondary secondary side fast charger, because the charging process is "backwar...

AI Technical Summary

Problems solved by technology

If all the charging piles are turned on but there are not many electric vehicles that need to be charged nearby, many charging piles will be idle for a long time without electric vehicles to charge, and a certain amount of power resources will be wasted. There are a lot of electric vehicles, which will lead to many electric vehicles queuing up for charging, which reduces the charging efficiency and brings bad experience to users

[0004] In addition, the structure of the charging pile in the prior art is not reasonable enough, and the function is relatively single, which cannot meet the needs of increasingly picky electric vehicle users.
