Description

Technical Field

[0001] The utility model relates to the technical field of battery protection plates, in particular to a lithium battery protection plate with an anti-fall protection function. Background Art

[0002] As we all know, the lithium battery protection board is a charge and discharge protection for the series lithium battery pack. When fully charged, it can ensure that the voltage difference between each single cell is less than the set value, so as to achieve equal charging of each single cell in the battery pack, effectively improving the charging effect under the series charging mode. At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit and overtemperature status of each single cell in the battery pack, protecting and extending the battery life.

[0003] In the prior art, when a lithium battery protection board is in use, the components and circuits on the protection board need to be protected to prevent the lithium battery protection board from being damaged when it falls, thereby extending the service life of the lithium battery protection board. The existing protection method generally provides a layer of protection board on the top and bottom surfaces of the protection board, which is connected by bolts and support sleeves outside the bolts. However, when the battery protection board falls, the protection board will directly collide with the ground and be damaged, or even break or bend, and needs to be replaced. At the same time, the vibration generated by the collision will be directly transmitted to the battery protection board through the bolts, causing the battery protection board to be subjected to greater vibration and damage to the components. The protection effect is relatively limited, and there are certain limitations. Utility Model Content
