Abstract

The invention discloses a battery pack device. The battery pack device comprises a plurality of basic parallel units, heat radiators, bus bars and insulation parts, wherein the bus bars are positioned between the heat radiators and the multiple basic parallel units, and are connected by screws of the heat radiators; pole lugs of the basic parallel units are connected in parallel by the bus bars; each basic parallel unit comprises a voltage collecting terminal; the insulation parts comprise first insulation parts, second insulation parts and third insulation parts; each first insulation part is fixedly arranged between each bus bar and the corresponding heat radiator through the screw of the heat radiator; each second insulation part is positioned around the screw of the corresponding heat radiator; each third insulation part is positioned at the boundary, corresponding to the voltage collecting terminal, of the corresponding heat radiator. The battery pack device has the advantages that when the heat is transferred by the pole lugs, the problem of electric insulation between the heat radiators and the basic parallel units is reliably solved, and the safety in use is improved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a battery pack device. Background technique [0002] Lithium battery technology has developed by leaps and bounds in today's society and has been successfully used in mobile devices such as mobile phones and computers. However, for high-power-consuming devices, lithium-ion single batteries with ordinary capacity often cannot meet the demand. Lithium-ion single cells need to be assembled into battery packs with different power and power according to different series and / or parallel ways to meet the needs of high-energy and high-power power equipment. [0003] Lithium-ion batteries will generate more heat during charging and discharging, and the high heat and temperature environment will seriously affect the performance of lithium-ion batteries, and even lead to safety accidents in use; and for lithium-ion batteries used in low-temperature environments , a suitable heat temperature envir...
