An electric vehicle battery pack automatic replacement system and battery transmission method thereof

Abstract

An electric vehicle battery pack automatic replacement system and a battery delivery method thereof, the system includes two transmission lines, a shifting device, a battery replacement device and a vehicle positioning platform, wherein the battery replacement device includes a dual positioning transfer vehicle and a lifting device. Two transmission lines for fully charged batteries and feed batteries are installed in parallel, and the double positioning transmission vehicles with two battery storage seats fixed together are placed between the two transmission lines and perpendicular to the transmission direction of the transmission line in three directions. Move within the area of ​​each station, the lifting equipment is set at the battery replacement station, the double positioning transfer vehicle places the fully charged battery conveyed by the loading conveyor line and the depleted battery unloaded by the lifting equipment moves to the side of the depleted battery seat for one station. The fully-charged battery is located on the electric replacement station, and the fully-charged battery is loaded by the lifting device, and at the same time, the depleted battery is removed from the depleted battery holder of the dual positioning transfer vehicle, thus completing the battery replacement.

Description

technical field [0001] The invention relates to a battery replacement system in the field of electric vehicles, in particular to an automatic battery replacement system for electric cars and its layout and operation method. Background technique [0002] Electric vehicles drive vehicles through the electric energy stored in batteries, which reduces the vehicle's dependence on fossil energy and is an important means to solve national energy security issues. Due to the limitation of the current battery energy density, the driving range of electric vehicles is usually 100 to 200 kilometers, which is far from the driving range of traditional cars, which usually exceeds 500 kilometers. Therefore, whether electric vehicles can be quickly and conveniently supplemented with electric energy will become an important factor affecting the use and promotion of electric vehicles. At the current level of battery technology development, battery charging usually takes several hours to comple...

AI Technical Summary

Problems solved by technology

Although this solution is feasible, the replacement of the battery can be completed in the end, but since there is only one transmission line, the fully charged battery must be loaded on the electric vehicle first, and the deficient battery can only be transferred after the fully charged battery is loaded. There are several stations away, so this disadvantage makes battery replacement time longer

Another disadvantage of this solution is that when multiple electric vehicles need to be replaced at the same time, multiple sets of battery replacement systems must be used, and a corresponding number of transmission lines must be added. Considering the needs of space layout, the length of the transmission line also needs to be adjusted. Extends as the number increases, poor scalability
