Abstract

The invention discloses a battery pack device, comprising: a plurality of basic parallel units, a radiator, a bus connection bar and an insulating part; the bus connection bar is located between the radiator and the plurality of basic parallel units, and is connected by radiator screws ; the bus connection bar connects the tabs of the basic parallel units to form a parallel connection; each of the basic parallel units includes a voltage collection terminal; the insulating parts include a first insulating part, a second insulating part and a third insulating part parts; the first insulating part is fixed between the bus connection bar and the radiator by the radiator screw; the second insulating part is located around the radiator screw; the third insulating part is located The radiator corresponds to the boundary of the voltage collection terminal. The battery pack device of the present invention reliably solves the electrical insulation problem between the radiator and the basic parallel units while utilizing the tabs for heat transfer, thereby improving the safety in use.

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...
