A lithium ion battery adapter plate and a lithium ion battery with the adapter plate

Abstract

The invention discloses a lithium ion battery adapter plate and a lithium ion battery with the adapter plate. The lithium-ion battery adapter board includes an adapter board body, which is provided with a sampling line interface for connecting the sampling line and several tab through holes for the tabs to pass through. One side of each tab through hole is There are corresponding pads, and each pad is connected to the corresponding terminal in the sampling line interface through a corresponding conductive line. A fuse is connected in series to the conductive line connected to one of the pads, and a conductive line connected to one of the pads is connected to the corresponding terminal in the sampling line interface. There are no electronic components connected in series, and resistors are connected in series on the conductive lines connected to other pads. The invention can limit the current passing through the sampling line when the sampling line is short-circuited, so as to prevent the sampling line from heating and igniting due to the excessive current passing through it, and also avoid burning itself due to the excessive current passing through it.

Description

technical field [0001] The invention relates to the technical field of adapter plates, in particular to a lithium-ion battery adapter plate and a lithium-ion battery with the adapter plate. Background technique [0002] During the use of the lithium battery system, when the electrolyte leaks abnormally, the leaked electrolyte will corrode the insulation layer of the adapter board, resulting in the exposure of the sampling line of the adapter board. The exposed sampling line in a humid environment is very easy to short circuit and cause a fire. . The existing battery adapter boards only have a simple transfer function and cannot prevent the sampling line from short-circuiting and igniting. [0003] Chinese patent document (publication number CN201072769) discloses an adapter board for assembling lithium-ion batteries in flexible packaging. The board is provided with neatly arranged long holes, and the same side board around the long holes is provided with metal-coated Weldi...
