Movable automatic power charging and switching station as well as cell rapid replacement method for electric automobile

Abstract

The invention discloses a movable automatic power charging and switching station for an electric automobile. The movable automatic power charging and switching station comprises a drawing automobile head, a semitrailer, and units, such as a cell storage cabin, a cell box, an automatic power switching device, an automatic charging and control system and the like which are mounted on the semitrailer. The cell storage cabin is a motor roller way cabin and can be used for storing a plurality of cell boxes; the cell boxes are standard exchange modules and connected with a cell cabin at the lower part of an automobile body by using a plurality of spring quick-open hooks; and the automatic power switching device comprises an electric motor roller, a removing apparatus for lines, a lifting platform and a plurality of unlocking / locking push rod mechanisms. The cell boxes are locked or unlocked with the cell cabin of the automobile body through mutual working of the lifting platform, the unlocking / locking push rod mechanisms and the quick-open hooks so that the dismounting and replacement of the cell boxes are realized; and a charger can be used for automatically charging the cell boxes. The movable automatic power charging and switching station has the advantages of complete system, tight structure, flexible mechanism, small construction investment and short period. Furthermore, the movable automatic power charging and switching station not only can be individually operated but also can combined with a centralized charging station to form a power switching network so that the requirement of automatically replacing the cells of the electric automobile is met.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a mobile automatic charging and replacing station for electric vehicles and a battery quick-changing method. Background technique [0002] Electric vehicles have the advantages of economical operation, clean and environmentally friendly, but due to the limitation of battery capacity, the mileage is short. At the same time, the popularization and application of electric vehicles is limited due to the long charging time, high battery cost and difficult maintenance. In order to prolong the driving range of electric vehicles, the method of battery replacement can be adopted. When the battery power is low, a fully charged battery can be quickly replaced at the battery replacement station. The battery replacement time is controlled within 3 minutes, which is similar to the refueling time of fuel vehicles. This not only prolongs the driving range, but also saves time. At the same time,...

Problems solved by technology

The construction of a fixed charging / swapping station involves many factors such as urban construction planning, land approval, environmental assessment, roads, and power supply. It takes a long time (usually as long as several months); the construction of a fixed charging / swapping station requires a large area, and a new factory building of thousands of square meters requires a huge construction investment (up to tens of millions of yuan). A large number of constructions on main roads; at the same time, electric vehicles need to be driven to fixed charging / replacing stations to replace batteries, which not only wastes energy, but also shortens the effective mileage of electric vehicles, and is extremely inconvenient

Due to the large area, large investment, and inconvenient layout of the fixed charging / swapping station solution, it is difficult to popularize in cities, which greatly affects the promotion and application of electric vehicles
