Abstract

The invention also discloses a power supply device, which comprises a battery module and a circuit protection board, wherein the battery module comprises an insulation shell and a plurality of monomer cells arranged in the insulation shell; a plurality of electric conduction sheets electrically connected with the monomer cells are also formed on the upper surface of the insulation shell; the battery protection board comprises a substrate, wherein a battery protection circuit and a plurality of electric conduction terminals corresponding to the monomer cells in the battery module are distributed on the substrate; the electric conduction terminals are arranged on two sides of the substrate at certain intervals; the battery protection circuit and the electric conduction terminals are electrically connected, one pair of power supply leading-out terminals are arranged to lead out or input the power supply of multiple groups of monomer cells, the electric conduction terminals and the electric conduction sheets are corresponded one by one, the positions of the electric conduction terminals and the positions of the electric conduction sheets are opposite, and electric conduction terminals and the electric conduction sheets are electrically connected when the circuit protection board is installed on the upper surface of the insulation shell. The electric conduction terminals and the electric conduction sheets in the battery module do not need to be electrically connected by a lead, and the problem of wiring errors is avoided.

Description

technical field [0001] The invention relates to a battery device, in particular to a power supply device with improved connection between a battery protection board and a battery module. Background technique [0002] The current power supply device, especially the power supply device involving a variety of single cells, its battery protection board needs to be electrically connected to several single cells respectively. The power cord of the battery cell is led out and welded to the interface of the corresponding battery protection board. There are many connections and the operation is complicated and error-prone. [0003] Therefore, there is an urgent need for a new power supply device that can solve the above-mentioned problems. Contents of the invention [0004] The purpose of the present invention is to provide a battery protection board and a power supply device, so that when the battery protection board is connected to the battery module, no lead wires are needed, a...
