Problems solved by technology
First of all, the proposed system only includes the connecting parts between the battery and the vehicle, without any positioning guide device, so its system cannot realize automatic battery replacement, and it does not have the ability to replace batteries for various models and battery boxes of various sizes ability
Secondly, its system needs to add two parts, the mounting plate and the protective frame, to the vehicle to fix the battery on the vehicle, which not only increases the weight of the vehicle, but also requires reliable contact between the mounting plate and the battery, the protective frame and the vehicle. connection, adding to the complexity of the system

The invention discloses an automatic battery replacing system of an electric automobile, which comprises a vehicle positioning platform, a positioning base, lifting equipment, a battery box and a battery box locking device. The vehicle positioning platform is arranged above the positioning base and the lifting equipment and used for positioning and parking a vehicle; a through opening is arrangedin the center of the positioning platform for dismounting and mounting the battery box; a controllable positioning mechanism is arranged between the lifting equipment and the positioning base; the positioning mechanism is used for realizing automatic positioning between the positioning base and the lifting equipment; a guiding device is arranged between the battery box and the vehicle for compensating position error when the battery box is mounted; and the battery box locking device is used for locking the battery box in the vehicle or unlocking the battery box. The invention further discloses a method for automatically replacing the battery of the electric automobile by using the system.
Description
technical field [0001] The invention relates to a battery replacement system for an electric car, in particular to an automatic battery replacement system for an electric car. The invention also relates to a method for automatic battery replacement of an electric vehicle. 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, batt...
