Electric automobile intelligent charging pile control method with high compatibility and high efficiency

Abstract

An electric automobile intelligent charging pile control method with high compatibility and high efficiency comprises the following steps of step 1, detecting gun inserting information; step 2, judging whether a server is turned on or not; and if the server is turned on, entering the next step; and otherwise, entering a step 7; step 3, communicating with an automobile BMS; step 4, judging whether entering a charging stage or not; and if entering the charging stage, entering the next step; and otherwise, entering the step 7; step 5, configuring charging module output according to needs of the automobile BMS; step 6, judging whether a turnoff or fault instruction is received or not; and if the turnoff or fault instruction is received, entering the next step; and otherwise, entering the step 5; step 7, entering a turnoff processing program; and step 8, finishing the control method. As the output mode of a power module is intelligent configured according to charging needs through communicating with the automobile BMS system in real time, the electric automobile intelligent charging pile control method with high compatibility and high efficiency is advantaged in that the compatibility of the control method is very high, the control method can mutually charge passenger vehicles and buses, the charging needs of all electric automobiles on the current market are satisfied, the whole control is convenient and simple, and the control method is convenient to operate and is also safe and reliable.

Description

technical field [0001] The invention relates to the technical field of new energy electric vehicle charging, in particular to a control method for an intelligent charging pile of an electric vehicle with high compatibility and high efficiency. Background technique [0002] With the growing problems of energy shortage and environmental deterioration, electric vehicles have become a new industry that countries are competing to develop with their advantages of energy saving and emission reduction. DC fast charging technology is widely used in the field of new energy electric vehicles. In the current market, electric vehicles require different charging voltages due to different manufacturers and models. At present, there are two types of charging piles in the market. One is high-voltage charging piles. This kind of charging piles is specially designed for charging vehicles with high voltage. . The other is a low-voltage charging pile, which charges the car. [0003] Due to th...
