A kind of output structure of lithium battery pack

Abstract

The invention discloses an output structure of a lithium battery pack, which comprises an electrode of the lithium battery pack, an insulating plate, a circuit board, a parallel conductor and a connector; Slits; the circuit board is provided with copper plating for each electrode in the lithium battery pack connected in series, and there are also through slits; the parallel conductor is a thin sheet structure, which is connected in parallel with the copper plating of the electrodes connected in series on the circuit board; the electrodes pass through the insulation The board and the circuit board are bent after the slit, and the circuit board, the insulating board and the battery pack are connected as a whole. The electrode bending surface, the circuit board insulating board and the connector are also provided with screw holes. The circuit board, insulating board and connector are tightly connected; the bolt connection will not generate heat during the implementation process, causing damage to the inside of the battery, and also reduces the possibility of heat accumulation caused by the connection between the lithium battery during use It is easy to disassemble and sort after the working life of the lithium battery pack is over.

Description

technical field [0001] The invention relates to a battery pack, in particular to an output structure of a lithium battery pack. Background technique [0002] Lithium batteries need to meet the output voltage or current requirements in the form of battery packs. It is difficult for a single-cell lithium battery to meet the output voltage or current requirements. This requires connecting lithium batteries to form an output structure of a battery pack to provide power to For use with external electrical devices. [0003] The output structure of the existing lithium battery pack includes electrodes for the output of a single-cell lithium battery, a connector connecting the electrodes of each single-cell lithium battery, and a connector connected to the connector, and the connector is connected to an external electrical device The shortcoming of the output structure of existing battery pack is: connector is directly connected with the electrode of lithium battery directly by sol...

[0003] The output structure of the existing lithium battery pack includes electrodes for the output of a single-cell lithium battery, a connector connecting the electrodes of each single-cell lithium battery, and a connector connected to the connector, and the connector is connected to an external electrical device The shortcoming of the output structure of existing battery pack is: connector is directly connected with the electrode of lithium battery directly by soldering, and soldering needs high-temperature treatment and processing time is long, easily causes the internal structure damage of lithium battery, simultaneously, welding The strength and conductivity of the parts are poor, which reduces the reliability of the connection between the connector and the electrode. The poor conductivity is prone to heat energy accumulation when the battery outputs a large current, causing the battery temperature to rise rapidly and affecting the battery life; Tin is prone to oxidation and corrosion. Once damaged, the battery must be repaired or discarded directly
