Power Battery Pack for AGV

With the continuous development of automation technology, automatic guided vehicle (AGV) has become an indispensable part of the modern production process. And the AGV power battery pack, as its power source, is also getting more and more attention. In this paper, we will discuss the types, characteristics, management system, charging strategy, safety and maintenance of power battery packs for AGVs to help readers fully understand the power battery packs for AGVs.
1、Types and Characteristics of Battery Packs
AGV power battery packs usually use lithium batteries, of which ternary lithium batteries as the mainstream. Lithium ternary batteries have high energy density, low self-discharge rate, long life and other characteristics, suitable for AGV power source. In addition, some special occasions, such as nickel-metal hydride batteries are also used. When selecting the battery pack, it is necessary to select the appropriate battery type and characteristics according to the specific needs of the AGV and the use of the environment.
2、Battery management system
AGV power battery pack needs an efficient and reliable management system to ensure its normal operation. Battery management system mainly includes the collection of battery information, management, maintenance and monitoring and other functions. Through the management system, the power, temperature, pressure and other parameters of the battery pack can be monitored in real time to prevent potential problems. At the same time, the management system can also automatically allocate power according to the operating status of the AGV to optimize the use of battery efficiency.
3、Battery charging strategy
The charging strategy of power battery pack for AGV includes charging method and charging process. Common charging methods include wired charging and wireless charging. Wired charging transmits power to the battery pack through cables, which has the advantages of fast charging speed and high efficiency, but requires the laying of cables and has certain requirements on the environment. Wireless charging, on the other hand, does not require cables and transmits power to the battery pack through a magnetic field, which has the advantages of convenience and flexibility, but the charging efficiency is relatively low.
In the charging process, it is necessary to ensure the safety and efficiency of charging. On the one hand, it is necessary to avoid damage to the battery caused by overcharging and overdischarging; on the other hand, it is necessary to shorten the charging time as much as possible and improve the charging efficiency. Some advanced charging strategies will also combine with the operation plan of the AGV to reasonably arrange the charging time and realize the maximum utilization of energy.
4、Battery safety and maintenance
The safety and maintenance of power battery packs for AGVs are crucial. First of all, to ensure the quality and reliability of the battery pack, to avoid the normal operation of the AGV due to battery failure. Secondly, we should pay attention to the charging safety of the battery pack to prevent overcharging, over-discharging and other dangerous situations. In addition, for different use environments and use requirements, the battery pack should be regularly inspected and maintained to extend its service life.
For the possible failures of the battery pack, corresponding maintenance strategies should be formulated. For example, regular charging and discharging maintenance of the battery pack to maintain the performance of the battery pack; for the faulty battery, it should be replaced or repaired in a timely manner to ensure the normal operation of the battery pack. At the same time, maintenance personnel also need to pay close attention to the operating status of the battery pack, found abnormalities in a timely manner to prevent the expansion of the failure caused by losses.
5、Battery pack application case study
Power battery packs for AGVs are widely used in various fields, such as manufacturing, logistics and medical industries. In the manufacturing industry, AGV power battery pack for automated production lines to provide power to achieve automated transportation of materials, semi-finished products, etc.; in the logistics industry, AGV power battery for the realization of automated access to warehousing and handling of goods to provide energy; in the medical industry, AGV power battery pack for medical equipment to provide power for the movement and operation. All these application cases show the importance and advantages of power battery packs for AGVs.
