Description

Technical Field

[0001] The utility model relates to a battery replacement station, in particular to a chassis battery replacement system for an electric truck. Background Art

[0002] In the field of electric trucks, the charging time is long due to the large number of batteries. In this field, the batteries are usually fixed on the mounting frame to form a battery pack that can be disassembled and replaced as a whole, and a battery swap station is set up specifically for charging the battery pack. When the battery on the vehicle is low on power, the vehicle can be driven to the battery swap station for battery replacement to avoid affecting the use of the vehicle.

This structure and battery swapping method not only affects the utilization rate of the space on the upper side of the frame, but also causes the overall height of the battery swap station to increase the structural complexity and construction difficulty, and the cost of use and maintenance is high.

In actual application, through the coordinated operation of the transfer lifting device 2, the battery storage device 3, the disassembly and transfer device 4 and the transfer and stacking device 5, the vehicle 100 with the battery 32 installed on the lower side of the chassis can be replaced. Compared with the prior art, it is not only beneficial to improve the space utilization rate of the vehicle, but also beneficial to reduce the height of the battery replacement station, thereby reducing the construction difficulty and maintenance cost of the battery replacement station. The specific process of battery replacement is as follows: 1. Drive the vehicle 100 that needs battery replacement to the upper side of the disassembly and transfer device 4; 2.
