Example Embodiment
[0045] Example one:
[0046] This embodiment provides a high-voltage power lithium-ion battery.
[0047] The high-voltage power lithium-ion battery 801 in the present invention is designed to meet the power supply requirements of various electric vehicles. Therefore, according to the different applications of the battery, the voltage design value of the battery cell 301 is also different, that is, the battery unit 201 constituting the battery cell 301 The number of overlays is different. At present, the working voltages of small electric vehicles (including electric bicycles, electric motorcycles and electric sightseeing cars, etc.) are generally: 36V, 48V, 64V, 74V and 80V. Large and medium-sized electric vehicles (including pure electric passenger cars and pure electric trucks) , Hybrid vehicles, electric buses, etc.) The working voltage range is generally 120V ~ 500V.
[0048] This embodiment is a pure electric passenger car power supply, its working voltage is 360V, the selecte...
Example Embodiment
[0058] Embodiment two:
[0059] This embodiment provides an elastic gasket 401 device for a high-voltage power battery.
[0060] In this embodiment, the elastic gasket 401 includes a circular gasket 402 and an elastic body 403a, wherein the elastic body is an elastic porous metal foam nickel, such as Figure 4 As shown in a, or it is a metal sheet with compression and resilience such as corrugated waves, cup-shaped plates, such as Figure 4 b and Figure 4 c is shown. The remaining structure of the battery is the same as in the first embodiment.
Example Embodiment
[0061] Embodiment three:
