Design and analysis of battery system for heavy-duty unmanned electric container transportation vehicle
Abstract
With the development of the port logistics which are going for large-scale, large-flow, high-speed. Large-scale container ships, large-tonnage containers, and the loading, unloading equipment and the supporting large-scale shore bridges have been built for it. This article mainly designs and analyzes the battery system of heavy-duty unmanned electric container transporter. After consulting the literature, and analyzing the environmental conditions and working requirements of the port AGV, finally GYS LIM50H-12 lithium ion battery is chosen as the battery module for the project, according to the data of the electric drive system from my partner to calculate the required power and he requirements of the target model to design The parameters of the electric vehicle system reasonably, determine the basic structure of a single battery pack, that is, 8 battery cells are connected in parallel to form a battery module, and 8 battery modules are connected in series to form a power battery pack. I designed the overwrap and the fixed way of the battery pack in view of the design of the car's driving conditions and speed. Simplified the battery cell model for temperature field analysis.
Key words: pure electric vehicle, battery pack, mechanical structure, thermal analysis
