Abstract

The invention relates to a lithium ion battery pack capable of converting a series-parallel connection. The lithium ion battery pack comprises an outer box with an upward opening, the battery pack is arranged in the outer box and is designed with a positive cylinder manifold and a negative cylinder manifold, convex terminal posts are fixedly connected to the positive cylinder manifold and the negative cylinder manifold, series boards or parallel boards which can be switched are connected to the convex terminal posts, the upper surfaces of the series boards are designed with coupling pins, the lower surfaces of the series boards are designed with connection straps, a terminal flow deflector is led out from the end part of each connection strap, 2P connectors and 4P connectors are connected at the connection straps by virtue of studs, concave terminal posts are connected at the 2P connectors and the 4P connectors and are connected with one another in series, a spring is designed between each concave terminal post and each series board, and each concave terminal post is corresponding to each convex terminal post.

Description

technical field [0001] The invention relates to a lithium-ion battery pack, in particular to a lithium-ion battery pack with series-parallel switching. Background technique [0002] There is a consistency problem in the lithium-ion battery pack, which is the main factor restricting the development of the lithium-ion industry. Although the lithium-ion battery packs currently on the market have adopted protective boards or management systems to eliminate individual differences between lithium-ion battery packs, the effect is not obvious, especially some lithium-ion battery packs with protective boards often have problems The most important place is the balance of the protection board. Large-scale lithium-ion battery packs have higher requirements for lithium-ion battery packs, and it is more difficult to achieve the consistency of lithium-ion battery packs. There are many series and parallel connections of large lithium-ion battery packs, and the structure is complex, which ...
