Replacing system of battery box of electric car

Abstract

The invention provides a replacing system and a replacing method for of a battery box of an electric car and belongs to the technical field of the electric car, which better solve the problem that in the prior art, the replacing station occupies large area. The replacing system comprises two replacing devices symmetrically arranged on both sides of a replacing position, a vertical guiding rail capable of moving along the incoming and outgoing directions of the car, a car locating device arranged on the replacing station, a sealed charge box, a battery holder in the charging box, and a charger, wherein, the vehicle positioning device, the charge box, the battery holder and the charger are arranged on the replacing station, the charge box is arranged right above or under the replacing position; a supporting frame is correspondingly arranged right above the replacing position; and a ground groove is correspondingly arranged below the replacing position. According to the replacing system disclosed by the invention, the charge box is stored by using the space right above or under the replacing position, so that the floor area of the replacing system is reduced by more than 50%. The three-dimensional draw-out type replacing mode is used in the replacing method, so that the battery is unnecessary to rotate in the replacing process, and is also unnecessary to be subjected to secondary transmission by using a stacker, and further, the replacing time is shortened.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle battery box replacement system and method. Background technique [0002] Electric vehicles use electricity as the main energy source, and have the advantages of low emissions and high energy efficiency, and are the main choice to replace fuel vehicles. In the context of increasingly prominent global energy and environmental problems, the development of electric vehicles has become an important way to get rid of dependence on oil resources, achieve energy conservation and emission reduction, and alleviate energy and environmental problems. [0003] There are currently three energy supplement modes for electric vehicles: AC charging, DC charging, and battery replacement. For large pure electric buses, the battery replacement mode is more suitable for the development of electric buses. In the battery replacement mode, the car is like a mob...

Problems solved by technology

[0011] The purpose of the present invention is to provide a battery box replacement system and method for an electric vehicle. The replacement system uses the space directly above or directly below the replacement station to store the charging box, so that the replacement system can save more than 50% of the floor space and solve the problem The replacement station has the disadvantage of large area; and the replacement method adopts the three-dimensional extraction replacement mode, the battery does not need to be rotated during the replacement process, and there is no need to use the stacker for secondary transfer, and the replacement time is shortened
