An electric vehicle intelligent charging system and charging method

Abstract

The invention relates to an electric vehicle intelligent charging system and charging method. The charging system includes a mobile phone client, a background server, an intelligent power supply device and a charging socket; the mobile phone client, the background server and the intelligent electric power supply device communicate through the Internet ; The intelligent power supply device charges the external rechargeable battery through the charging socket. The charging method includes: the rechargeable battery is connected to the charging socket through the power cord; the intelligent power supply device sends the charging current and the remaining power of the rechargeable battery to the background server; the background server sends the time and cost of full charging to the mobile client, and the mobile client will The information of whether charging is fed back to the background server; the background server notifies the intelligent power supply device to choose to charge or not to charge the rechargeable battery according to the information fed back by the mobile phone client. The beneficial effects of the invention are: it is suitable for popularization and application, and it is convenient for users to charge the rechargeable battery of the electric vehicle conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle intelligent charging system and a charging method. Background technique [0002] As an economical, convenient and energy-saving means of transportation, electric bicycles occupy a large market in our country. At present, electric bicycles are mainly powered by lead-acid batteries. Due to the limitation of battery storage capacity, electric bicycles must use chargers to charge the batteries after driving a certain mileage. [0003] The charging methods of existing rechargeable batteries are roughly divided into the following three types: 1) The electric vehicle users solve it by themselves. The user pulls out a power cord from home to charge the electric vehicle. This is the mainstream charging method for most electric vehicle users at present. This charging method makes cobweb-like power lines everywhere in the community, which h...

Problems solved by technology

[0003] The charging methods of existing rechargeable batteries are roughly divided into the following three types: 1) The electric vehicle users solve it by themselves. The user pulls out a power cord from home to charge the electric vehicle. This is the mainstream charging method for most electric vehicle users at present. This charging method makes spider web-like power lines everywhere in the community, which is unsightly, unsafe and inconvenient

2) Residential property provides ordinary charging sockets in the carport. This charging method is rarely used at present. Due to reasons such as electricity bills, maintenance, management and safety hazards, the residential property tolerates electric vehicle users in the community to solve electric vehicle charging by themselves to the greatest extent. problems without improving the infrastructure

3) Some businesses provide fast charging stations for electric vehicles, which are usually placed near the downtown area and cannot really achieve the purpose of convenience

In addition, this kind of fast charging station technology is not perfect, and basically uses deep negative pulse technology for charging. This method cannot fully charge the rechargeable battery. Electric car users have to recharge the rechargeable battery after returning home

Moreover, continuous high-current power supply is feasible for occasional use, and frequent charging in this way will cause great damage to the rechargeable battery
