Automatic battery pack changing system for electric automobile and battery conveying method thereof

Abstract

The invention provides an automatic battery pack changing system for an electric automobile and a battery conveying method thereof. The system comprises two conveying lines, a shifting device, battery changing equipment and a vehicle positioning platform, wherein the battery changing equipment comprises a coupled twin positioning conveying vehicle and a lifting device; two conveying lines respectively used for conveying a full battery and a feed battery are arranged in parallel; the coupled twin positioning conveying vehicle provided with two battery storing seats fixed together move between the two conveying lines in three station areas vertical to a conveying direction of the conveying lines; the lifting device is arranged on a battery changing station; the coupled twin positioning conveying vehicle loads the full battery conveyed by the conveying line and the feed battery unloaded by the lifting device and moves one station to one side of the feed battery seat; the full battery is arranged on the battery changing station; the lifting device loads the full battery; and at the same time, the feed battery is unloaded from the feed battery seat of the coupled twin positioning conveying vehicle, so that the changing of the batteries is finished.

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...

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
