Charging Strategy for AGV Lithium Battery Packs

Reasonable charging strategy is the core guarantee to extend the service life of agv lithium battery packs and maintain continuous and stable operation of automated handling equipment. In actual industrial scenarios, users need to make targeted adjustment of charging schemes according to the battery's state of health, ambient temperature, and daily operation scheduling rules, instead of adopting a unified non-differentiated charging mode. First, the peak-valley staggered charging strategy is recommended for most application scenarios. Users can set the charging start time at the off-peak period of local power consumption, which not only reduces the overall electricity cost of the enterprise, but also avoids the impact of unstable grid voltage during peak power consumption period on the battery cell consistency, effectively reducing unnecessary battery loss. Second, the segmented constant current and constant voltage charging strategy should be strictly implemented. In the early stage of charging, properly control the charging current within the safe range according to the rated parameters of the battery pack, avoid long-term high current fast charging when the remaining battery power is higher than 80%, and stop the charging process in time when the battery is full, to prevent the safety risk caused by overcharging. Third, dynamic charging scheduling can be matched according to the AGV operation plan. When the AGV completes a handling task and the remaining power is higher than 40% without continuous task arrangement, it can arrange a short-time supplementary charging properly, so as to avoid the battery being in a low power state of less than 20% for a long time, which is helpful to maintain the activity of battery materials. Jianshu New Energy has accumulated rich practical experience in the research and development of AGV supporting lithium battery and charging management system, and related solutions are well compatible with the product system of BYD Forklift.

Regularly check the temperature of the battery pack and the contact state of the charging interface during daily use, and timely clean up the dust and sundries on the surface of the charging contact, which can further reduce the hidden danger of charging and ensure the long-term stable operation of the AGV equipment.
