Electric vehicle battery centralized management and maintenance system and method

Abstract

The invention discloses an electric vehicle battery centralized management and maintenance system and method. The system comprises a large charging station, a fixed battery replacement point, a movable battery replacement car, batteries, a server, an RFID (radio frequency identification device) handheld terminal and a handheld user terminal with a battery centralized management and maintenance system APP (application), a battery charging area, a battery detection and maintenance area and a battery storage area are arranged in the large charging station, and the batteries are provided with RFIDlabels and state detection units. The system has the advantages that battery replacement operation is performed by a worker in the whole process, convenience is brought for a user, damage to the battery in disassembly can be maximally avoided, battery recovery and external assignment are recorded by the aid of a radio-frequency technique, information is accurately recorded, the batteries are charged in a centralized manner, battery management and maintenance are facilitated, the system is applicable to various types of batteries and can provide a corresponding charging mode for each type of batteries, the batteries are charged at peak-valley points, commercial power resources are reasonably used, and commercial power pressure is reduced.

Description

technical field [0001] The invention relates to the field of battery centralized management, in particular to a system and method for centralized management and maintenance of electric vehicle batteries. Background technique [0002] With the improvement of people's awareness of environmental protection, the number of electric vehicles is increasing, but electric vehicles have the following problems: the single mileage of electric vehicles is limited by the battery power, and the battery can only be carried out after a long period of charging. For the electric vehicle users living in the city, it is very difficult to charge the electric vehicle due to the limitation of the living floor and the limitation of the charging point when going out. Charging lines, leading to major safety hazards in the community. [0003] Chinese Patent Publication No. CN106451622A, published on February 22, 2017, the title of the invention is an electric bicycle charging system with centralized c...

Problems solved by technology

[0002] With the improvement of people's awareness of environmental protection, the number of electric vehicles is increasing, but electric vehicles have the following problems: the single mileage of electric vehicles is limited by the battery power, and the battery can only be carried out after a long period of charging. For the electric vehicle users living in the city, it is very difficult to charge the electric vehicle due to the limitation of the living floor and the limitation of the charging point when going out. Charging lines, leading to major safety hazards in the community

There are the following disadvantages: all operations are performed by the user himself, and there is a risk of battery damage or safety accidents caused by improper user operation; the charging method of the battery is fixed, and the corresponding charging mode cannot be used to charge the battery according to the battery model and power, and the battery is not used. Long-term use; when charging the electric car, the electric car cannot be used or needs to be equipped with a spare battery
