Problems solved by technology

All single lithium batteries are closely arranged together, which is not conducive to heat dissipation during charging and discharging of lithium batteries, and heat accumulates around the battery, which will reduce battery life
Moreover, the electric vehicle walks on different roads, and there will be certain vibrations on the battery. This kind of vibration will usually loosen the connection of the battery.

Embodiment Construction

[0010] Arrange the copper tubes in rows, spot weld between the two copper tubes, make it into a whole, flatten and paste a piece of sealing copper sheet 13 on its both sides respectively, make the copper tube row and the flexible package lithium battery 5 contact surface be a plane, prevent When the soft-packaged lithium battery 5 is crushed and the silicone rubber 6 is filled, it flows into the main air duct 11 and the sub-air duct 13 , and the whole serves as a heat dissipation metal channel 3 . Or use a hollow metal sheet with good thermal conductivity, such as an aluminum alloy, as the heat dissipation metal channel 3 . The heat dissipation metal passages 3 are arranged in parallel, and the connecting plate 8 is welded on the lower ends of the two heat dissipation metal passages 3, so that a space is formed between the two heat dissipation metal passages 3, which is just enough to accommodate the next single flexible package lithium battery 5, and is pierced with a conducti...

Abstract

The invention discloses a soft-packaged dynamic lithium battery group, comprising: multi-section soft-packaged lithium batteries (5) provide high voltage to the automobile by connecting in series, each soft-packaged lithium battery is placed between two heat emission metal channels (3) which has a through hole in the center and flats on the two ends, placing the assembly in a battery group outer case (2) and filling silicon rubber (6), the air get into the heat emission metal channel (3) central through hole from the air inlet located in the bottom corner of the group outer case (2) and out from the air outlet.

Description

Technical field: [0001] The invention relates to a power battery pack for an electric vehicle. The battery pack is provided with a high voltage by a plurality of soft-packed lithium batteries connected in series. There is a ventilation channel for heat dissipation between the lithium batteries and is filled with silicon rubber. More specifically, it relates to a stable performance, A soft-packed power lithium battery pack with heat dissipation ventilation channels and anti-aging properties. Background technique: [0002] As a new type of non-polluting secondary battery, lithium battery has been widely used in many fields, especially as a power battery for electric vehicles. The nominal voltage of the currently used single lithium battery is usually 3.6V, and the battery pack used for electric vehicles needs to be connected in series with more than 80 single lithium batteries, which are directly placed in a box after being connected in series. All single lithium batteries ar...
