Intelligent charging system and method for electric vehicle

Abstract

The invention discloses an intelligent charging system and method for an electric vehicle. The intelligent charging system is composed of a server, one or more intelligent gateways and one or more intelligent charging terminals. The server is installed in a control center, the intelligent gateways are installed in different charging points, and the intelligent charging terminals are installed at different charging positions of the charging points. The intelligent charging terminals are connected to the intelligent gateways, and the intelligent gateways are connected to the server. Each intelligent gateway includes a power module, a single chip control module, a serial interface circuit, an Ethernet communication module and a wireless communication module. The intelligent charging system and method utilize the technology of Internet of Things, through a wired or wireless method, the server is used for performing remote monitoring and parameter modification, and the scattered charging terminals are centrally managed to solve the situation that existing charging terminals are under independent control and centralized network management is not performed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle intelligent charging system and method. Background technique [0002] Electric vehicles have become the most popular means of transportation for Chinese people due to their outstanding advantages such as portability, environmental protection, low price, and moderate speed. According to incomplete statistics, the number of registered electric vehicles has reached 220 million. And it is increasing at a rate of 30 million vehicles per year. With the rapid growth of the number of electric vehicles, the related problems caused by charging have become increasingly prominent, which are mainly reflected in the following aspects: [0003] Electric vehicle owners cannot charge on demand, leading to overcharging of some electric vehicles, which will greatly shorten the service life of batteries, increase environmental pollution caused by battery recyc...

Problems solved by technology

[0004] Most of the charging equipment on the market charges electric vehicle charging fees according to the monthly subscription fee, which makes consumers have great doubts about the rationality of the charges, and the billing method is unreasonable

Since there is no centralized charging and management place, many users often pull wires from their residences to the ground to charge electric vehicles, which will inevitably lead to disorderly placement, traffic jams, chaotic management, and increased hidden dangers of electric leakage, especially for children. potentially great threat

[0005] At present, there are mainly centralized charging systems on the market. Most of the centralized charging terminals have a small number of charging ports, no safety protection function, and many cables. Each port is connected in one piece. When maintaining, it needs to be disassembled and installed as a whole. Servers, charging terminals, There are many interactions between users, and the power consumption of each charging is large. Some messages cannot be notified and returned to users in time. The payment method is cash payment, and the power consumption is also counted together, which is inconvenient to manage.
