Technical Field

[0001] The utility model relates to the technical field of lithium batteries for AGVs, in particular to a low-temperature charging and heating lithium battery pack for AGVs. Background Art

[0002] As the energy source of AGV, the performance of lithium batteries directly affects whether AGV can operate stably, efficiently and reliably, and is related to the service life of AGV. The battery cell is an important component of the lithium battery assembly, providing power for the battery. Lithium batteries have the characteristics of high energy density, high power density, long life and environmental protection. They have been used in the AGV industry. AGV lithium batteries have large capacity and can ensure that they are maintained within a reasonable range to prevent damage to the battery due to overcharging or over-discharging.

[0003] The use of AGV lithium batteries will be affected by low temperature weather. The lithium batteries need to be charged and heated to ensure the normal operation of the lithium batteries and prevent the batteries from being unable to charge and discharge continuously and stably in low temperature weather, affecting their use. Secondly, during the use of the battery, since the AGV is in continuous motion, the battery needs to be fixed and accurately positioned to prevent the movement of the AGV from causing displacement of the battery. Finally, the battery can be quickly removed and replaced. When the battery is exhausted or needs to be replaced due to other factors, it can be ensured that the battery can be quickly removed and replaced. Therefore, in response to the above problems, a low-temperature charging and heating lithium battery pack for AGV is proposed. Utility Model Content
