For the selection of reasonable AGV lithium battery,we analyze the development conditions and relative merits of foreign lithium batteries and compare different lithium batteries under Yangshan Phase IV’s unique operation requirements and overall layout conditions.Eventually we choose GSY LIM50H-12 15S10P lithium battery,which not only meet the requirements of the AGV 8 hours continuous operation,but also satisfy the battery radiator installation,in case of the battery overheat.
