Description

A replacement system for a power battery box

technical field

The utility model belongs to the field of electric vehicles, in particular to a replacement system for a power battery box. the

Background technique

Electric vehicles use electricity as the main energy source, and have the advantages of low emissions and high energy efficiency, and are the main choice to replace fuel vehicles. In the context of increasingly prominent global energy and environmental problems, the development of electric vehicles has become an important way to get rid of dependence on oil resources, achieve energy conservation and emission reduction, and alleviate energy and environmental problems. the

One of the core technologies of electric vehicles is the energy storage and supply system. The use of batteries and rapid replacement technology has become a key technology for the industrialization of electric vehicles. At present, due to factors such as driving range, pure electric vehicles are equipped with a large number of battery packs and their locations are not uniform, resulting in the battery box not being able to be replaced conveniently and quickly. the

At present, the battery box replacement of electric vehicles is mainly done by unloading the battery from the car, rotating it 180 degrees on the replacement device, and then putting the exhausted battery into the battery rack. The replacement device requires a large rotation space, so the operation of the replacement device takes up a lot of space. The replacement space is limited, and the rotation speed is difficult to select, the rotation is fast, and the battery is easy to be thrown out, and the rotation is slow, which reduces the efficiency and takes up a lot of space. For example, Wang Zhenpo of Beijing Institute of Technology and others applied for the invention patent of "quick replacement system for electric vehicle power battery pack", the application number is CN200810009129.3. The quick replacement system includes a quick-release mechanism and a transfer mechanism. The quick release mechanism includes a vacuum or electromagnetic chuck that can pull the battery box out of the electric vehicle body or push it into the electric vehicle body. The transfer mechanism adopts the working mode of three-coordinate translation plus rotation, so that the disassembled battery box can be transferred to the charging rack and/or the battery box removed from the charging rack can be inserted into the electric vehicle, thereby Complete the mechanical quick loading and replacement of the electric vehicle power battery pack. The system adopts the working mode of translation plus rotation. the

Other research on EV battery box replacement technology includes:

The application number is CN200910090807.8 and the invention title is "a power battery replacement system and replacement method for electric vehicles". It includes lifting equipment, lifting fulcrum, replacement equipment, and battery storage platform. The replacement equipment is responsible for multiple functions such as positioning, replacement, and stacking at the same time, which makes the replacement equipment larger in size and lower in replacement efficiency. the

Another example is the invention patent application with the application number CN201010603039.4 titled "An automatic quick-change system and automatic quick-change method for electric vehicle batteries", which can meet the automatic and fast change of electric vehicle battery boxes. The lower battery compartment, battery box and lifting platform. This patent application only discloses the device and method for quick battery replacement, but it does not involve how to charge the battery that is deficient in power. A system that does not match the charging of a deficient battery with the installation of a fully charged battery cannot be called a complete battery replacement system. . the

The new application with the application number CN201110096497.8 in 2011 announced a battery replacement system and its replacement method for portable electric vehicles, which solved the problem of being unable to replace the battery of a car and urgently needing to replace the battery while driving, and can directly Replace electric vehicle batteries. The system is equipped with: foldable electro-hydraulic lifting platform, battery box lifting platform trolley, battery box tray and integrated control platform. This device is suitable for long-time driving vehicles to carry, but in practical applications, the driver has to carry both a fully charged battery and a battery replacement device, which is extremely unfavorable to the promotion of electric vehicles. the
