Description

Technical Field

[0002] A large-capacity on-board power battery for an AGV (automatic guided vehicle) is a high-capacity battery system specially designed to drive the electric power source of an automatic guided vehicle. An AGV vehicle is an automated transport tool commonly used in factories, warehouses, and logistics centers to achieve autonomous handling and transportation tasks. This large-capacity on-board battery is designed to provide sufficient power to meet the needs of long-term operation of AGV vehicles, thereby reducing the frequency of battery replacement and maintenance costs. This battery usually adopts high-energy-density lithium-ion battery technology to ensure high-performance and stable energy supply, thereby improving the efficiency and reliability of AGV vehicles, while reducing dependence on traditional fuel power and promoting industrial automation and green energy use.

[0003] At present, the number of AGV vehicles on the market is increasing, but they generally have problems such as limited capacity and low space utilization, which leads to a series of challenges. First, due to the small capacity of traditional batteries, AGV vehicles need to be frequently charged or replaced, which not only increases operating costs, but also wastes valuable production time. The production line has to be interrupted, which directly damages production efficiency; in addition, AGV vehicles usually operate in limited spaces such as factories, warehouses and logistics centers, so higher space utilization is required. Small-capacity batteries not only limit the operating time, but also require AGV vehicles to frequently return to charging stations, wasting potential efficiency in transportation and handling tasks. This limitation also makes it difficult for AGV vehicles to meet large-scale logistics needs because they cannot cover a large area of ​​transportation tasks in a short period of time. To this end, we propose a large-capacity on-board power battery for AGV vehicles to solve the above-mentioned problems. Utility Model Content
