Intelligent charging system for electric vehicle and charging method

Abstract

The invention relates to an intelligent charging system for an electric vehicle and a charging method. The charging system comprises a mobile phone client, a background server, an intelligent power supply device and a charging socket, wherein the mobile phone client, the background server and the intelligent power supply device communicate with one another through internet; and the intelligent power supply device is used for charging an external rechargeable battery through a charging socket. The charging method comprises the steps as follows: the rechargeable battery is connected with the charging socket through a power line; the intelligent power supply device transmits charging current and the residual electricity quantity of the rechargeable battery to the background server; the background server transmits the time and cost required for fully charging to the mobile phone client; the mobile phone client feeds the information that charging is carried out or not back to the background server; and the background server informs the intelligent power supply device to select charging or non-charging of the rechargeable battery according to the information fed back by the mobile phone client. The intelligent charging system has the beneficial effects that the intelligent charging system is suitable for popularization and application; and conveniently and rapidly charging the rechargeable battery of the electric vehicle by a user is facilitated.

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 my country. At present, electric bicycles are mainly powered by lead-acid batteries. Due to the limitation of the storage capacity of the batteries, the electric bicycles must be charged with a charger after a certain mileage. [0003] The existing charging methods of rechargeable batteries are roughly divided into the following three types: 1) The electric vehicle users can solve it by themselves. The user charges the electric vehicle by pulling a power cord from the home. This is the mainstream charging method for most electric vehicle users at present. This charging method makes cobweb-like power cords visible everywhere in the commun...

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
