[0002] With the rapid development of new energy vehicles, more and more electric heavy trucks or electric engineering vehicles adopt the battery swap mode, and the number of corresponding battery swap stations is also growing rapidly. At present, there is a battery swap solution that combines a mobile battery swap station or a mobile battery swap vehicle with a battery delivery vehicle, which solves the dependence of building-type battery swap stations or skid-mounted battery swap stations on land facilities and power facilities. It is more flexible than building-type battery swap stations or skid-mounted battery swap stations and can be relocated based on the working location of the battery swap vehicle. As the main equipment of the mobile battery swap solution, the delivery vehicle has also seen a certain increase in demand.

[0003] In the prior art, battery delivery vehicles usually adopt an integrated truck solution, in which the trailer flatbed, base and battery are installed in an integrated manner. This solution results in a dedicated vehicle, and the vehicle cannot be used in a rental manner, which increases the cost of use. In addition, when the vehicle needs to transport batteries of different models, a large number of modifications are required to make it suitable for the second model of battery. Similarly, when the flatbed truck has a serious malfunction, accident, or needs to be replaced for other reasons, it is necessary to purchase a new truck for modification to be suitable for the batteries transported by the original delivery vehicle, resulting in excessively long replacement time and increased costs. That is, the interchangeability of each module in the prior art solution is poor, resulting in lack of flexibility, low efficiency and high cost.
