Description

Technical Field

[0001] This utility model relates to the field of new energy battery swapping technology, and in particular to a power supply system and an electric vehicle having the same. Background Technology

[0002] Compared to traditional fuel-powered trucks, new energy electric vehicles are more environmentally friendly, and their operating costs are not affected by fluctuations in oil prices, making cost control more effective. Existing new energy electric vehicles typically use power batteries to provide electricity, generally employing either charging or battery swapping modes. Some existing technologies also utilize both charging and battery swapping capabilities. However, the power supply systems in existing electric vehicles address a relatively simple power supply issue, only requiring the power battery to provide electricity to the vehicle. This limits their application scenarios. For example, they cannot expand the number of batteries to increase the driving range, nor can they use the vehicle's power battery to power external electrical equipment. Therefore, it is necessary to develop a more optimized power supply system and apply it to new energy electric vehicles, enabling existing new energy electric vehicles to expand the number of batteries according to driving range requirements, while also serving as a mobile power source to power external electrical facilities.
