Abstract: Light-duty trucks are the main force in urban distribution, and their electrification process is the key to the low-carbon transformation of urban logistics. Charging light trucks have three major problems: slow charging, short range, and high cost, which severely restrict the large-scale promotion. However, battery swapping light trucks can simultaneously solve the problems of charging, range, and cost, and are the key to breaking the deadlock. This article conducts a systematic study on the matching design of the vehicle, battery, and battery swap station, and through comparative analysis and experimental verification methods, concludes that the single-pack fully automatic battery swapping system has more packs than the conventional battery swapping system, and the swapping efficiency can be increased by 50%, and the construction cost can be reduced by 50%. This is the current optimal battery swapping solution for light trucks. The solution is highly innovative and practical.
