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...
