Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a new energy vehicle with battery replacement. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels but adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Such vehicles can effectively reduce dependence on traditional fuels and reduce pollutant emissions, and include pure electric vehicles, plug-in hybrid vehicles, fuel cell vehicles, etc.

[0003] The battery of new energy vehicles is one of the core components of new energy vehicles. They provide power for the vehicles. There are many types of batteries for new energy vehicles, each with its own unique characteristics and advantages. At present, the mainstream new energy vehicle batteries on the market mainly include lithium batteries (such as ternary lithium batteries and lithium iron phosphate batteries), hydrogen fuel cells, etc.

[0004] New energy vehicles have significant advantages in that their batteries can be replaced during use. Compared to the charging mode, the battery replacement mode has a faster recharge speed, which generally only takes a few minutes to complete. This greatly improves the travel convenience of new energy vehicles. Users no longer need to wait for a long time to charge, reducing the time wasted on charging. In the battery replacement mode, the battery is centrally monitored, managed and maintained by a professional operating company, which helps to extend the service life of the power battery. Professional maintenance and management can promptly detect and resolve potential battery problems, ensuring that the battery is always in good working condition. The battery replacement mode can also improve the safety of the battery. Since the battery is uniformly managed and maintained by a professional company, the quality and performance of the battery can be more strictly controlled, reducing safety accidents caused by battery problems.

[0005] Therefore, it is necessary to design a new energy vehicle with battery replacement that is practical and can quickly replace batteries. Summary of the invention
