Method and device for battery replacement by battery replacement mobile station for electric vehicles

Abstract

The invention discloses a method and device for automatically replacing battery of an electric vehicle by using a battery replacement mobile station and relates to the field of battery replacement ofthe electric vehicle. The method comprises the steps that the battery replacement mobile station receives mobile battery replacement requirements which are initiated by a user terminal, the mobile battery replacement requirements are parsed, and license plate number information and battery replacement information which are carried by the mobile battery replacement requirements are obtained; the battery replacement mobile station detects the electric quantity of the battery of the electric vehicle corresponding to the license plate number information, and determines whether or not the battery of the electric vehicle needs to be charged; if yes, the battery replacement mobile station reaches designated battery replacement positions of the mobile battery replacement requirements, and the battery, which needs to be charged, of the electric vehicle is replaced with a battery, which is full of electricity, in a same type; the number of the battery which is full of electricity is bound with the license plate number of the electric vehicle, and the number of the battery which needs to be charged is unbound with the license plate number of the electric vehicle.

Description

technical field [0001] The invention relates to the field of battery replacement for electric vehicles, in particular to a method and device for battery replacement by a battery replacement mobile station for electric vehicles. Background technique [0002] At present, electric vehicles generally have mileage concerns, and common solutions include: [0003] (1) Fast charging; [0004] (2) Replace the battery. [0005] Among them, there are many problems in fast charging, as follows: [0006] a. The battery loss is large, and the battery life is greatly reduced; [0007] b. High requirements for charging hardware facilities and large hardware loss; [0008] c. There are not many places where fast charging can be performed, and it must be connected to the car, which occupies a large area and has low land utilization. [0009] If the energy station (i.e. battery replacement fixed station) is used to centralize normal speed charging, the electric vehicle arrives at the ener...

Problems solved by technology

[0008] c. There are not many places where fast charging can be done, and it must be connected to the car, which occupies a large area and low land utilization rate

[0009] If the energy station (i.e. battery replacement fixed station) is used to centralize normal speed charging, the electric vehicle arrives at the energy station to replace the battery (i.e. battery replacement) in principle, there is no such problem. The disadvantage is that it is more troublesome to replace the battery, and it can only be replaced at the energy station. , that is, the battery cannot be exchanged outside the energy station
