Battery replacing method, battery replacing system and battery rack of electric vehicle

Abstract

The invention discloses a battery replacing method, a battery replacing system and a battery rack of an electric vehicle. In the invention, the battery replacing system comprises the fixed battery rack, a ferry vehicle, a stocker and a manipulator, wherein the ferry vehicle is movably arranged in the battery rack, a battery temporary storing place is arranged on the ferry vehicle, and the stockeris movably arranged at one side of the batter rack and the manipulator is movably arranged at the other side of the battery rack. The replacing method comprises the steps of: taking out a charged battery, moving to the ferry vehicle and putting the charged battery on the ferry vehicle by utilizing the stocker; taking out an uncharged battery on the electric vehicle and putting on the ferry vehicle by utilizing the manipulator; shifting the charged battery and the uncharged battery which are loaded on the ferry vehicle, for one station, aligning to the manipulator and placing the charged battery on the ferry vehicle on the electric vehicle by utilizing the manipulator so as to complete a replacing motion. In addition, a universal ball capable of autorotation and guide rolls arranged shapedlike a horn are arranged in a unit grid on the battery rack so that the battery can be more conveniently and rapidly guided to be put in the battery rack.

Description

technical field [0001] The invention relates to a battery replacement method and system for a vehicle-mounted power battery, in particular to a battery replacement method and a battery replacement system for an electric vehicle. Background technique [0002] Generally, existing electric vehicles are driven by rechargeable batteries. When the rechargeable batteries are used up, they need to be replaced. Because electric vehicles, especially larger electric vehicles, such as buses, require larger batteries and are relatively It is heavy, and generally multiple batteries or multiple battery packs are required on an electric vehicle, so a special system and specialized technicians are required to control the battery replacement, and the battery needs to be stocked, maintained and charged, etc., so It is a technical problem to be solved at present to propose a battery replacement system and method that saves time and effort and occupies a small area.
