In the automatic upgrading of intelligent factories and warehousing logistics, the battery selection of AGV (automatic guided vehicle) is an easily underestimated decision. Whether a set of AGV system can achieve 24 hours of continuous operation, the cycle life of the battery, the charging rate and the intelligence degree of the BMS are often more critical than the equipment itself.

From the perspective of cell system, lithium iron phosphate (LFP) is currently the mainstream choice for AGV applications. Compared with lead-acid batteries, the cycle life of lithium iron phosphate can reach more than 3500 times (80% DOD condition). It supports 1C fast charge and can be fully charged in about 1 hour.. Some storage robot application scenarios even require a cycle life of 4,000 to 8,000 times to meet the working conditions of high-frequency charging and discharging.. This means that a well-designed lithium iron phosphate battery package may only need to be replaced once or even without replacement during the life cycle of the AGV device.

But cell is only the starting point. The real threshold of AGV Battery lies in the design of BMS. In industrial scenarios, BMS is required to have real-time acquisition capabilities of single voltage, temperature, and current. The active equilibrium current is not less than 2A, the SOC estimation accuracy is controlled within ± 3%, and CAN, CANopen, communication protocols such as RS485 can connect data with the AGV controller and scheduling system.. At the level of safety protection, overvoltage, undervoltage, overcurrent, short circuit, over temperature, low temperature, reverse connection and other protectionProtection function is indispensable.

Dongguan Juneng New Energy Technology Co., Ltd. has made targeted optimization in lightweight design, intelligent management system and runtime length for the use scenarios of automatic navigation vehicles in the customization of AGV power batteries. The company adopts the "One scenario one strategy" approach in the design of the BMS-the BMS of the AGV Battery emphasizes the real-time communication and predictive maintenance capability with the scheduling system, rather than simply applying a general scheme.

Judging from the industry trend, the global mobile robot lithium battery market is maintaining steady growth. 2024 global mobile robot lithium battery the market size is about US $0.386 billion and is expected to grow to US $0.66 billion by 2031.. As the dependence of warehousing logistics and intelligent manufacturing on automation equipment continues to increase, the selection decision of AGV batteries will increasingly test the depth of PACK factory's understanding of industrial scenarios. The accumulation of new energy sources in this field deserves to be included in the investigation list.
