Embodiment 1

[0028] see figure 1 and Figure 4 , an embodiment provided by the present invention: a low-temperature preheating system for power battery packs for new energy vehicles, including a side plate 2, a cover plate 1 and a bottom plate 36 are connected to the side plate 2, the cover plate 1, the side plate 2 and the The bottom plate 36 is provided with a pipe port 3, and after the cover plate 1, the side plate 2 and the bottom plate 36 are assembled, a storage tank 38 is formed inside for placing the battery pack 7, and the battery pack 7 is provided with a second T-shaped slot 32, the second T A sponge 8 is slid in the shaped groove 32, and an adjustment component is connected to the sponge 8. The adjustment component pulls the sponge 8 to slide in the second T-shaped groove 32 for absorbing the water droplets 33 attached to the outer wall of the battery pack 7 when the heat and cold alternate.

[0029] In this embodiment: when using the heating device to heat water, the water fl...

Embodiment 2

[0031] This embodiment is an improvement made on the basis of Embodiment 1, see Figure 1 to Figure 4 , the adjustment component includes a processing plate 6, the processing plate 6 slides on the inner wall of the side plate 2, a second through hole 23 is opened on one side of the processing plate 6, a first one-way valve 4 is arranged in the pipe port 3, the first one-way The valve 4 is connected to the processing plate 6 through the steel cable 5, and the first one-way valve 4 is opened by the pressure of the water flow in the pipe port 3 to carry out the water circulation, and the rotation and swing of the first one-way valve 4 is used to pull the processing plate 6 to move up and down to drive the sponge 8 Move up and down to absorb the water droplets 33 attached to the outer wall of the battery pack 7 when the battery pack 7 alternates between cold and heat.

[0032] In this embodiment: the first one-way valve 4 is arranged in the pipeline mouth 3, when the water flow in...

Embodiment 3

[0034] This embodiment is an improvement made on the basis of Embodiment 1, specifically refer to Figure 1 to Figure 6, the regulating part includes a processing plate 6, the processing plate 6 slides on the inner wall of the side plate 2, a second through hole 23 is opened on one side of the processing plate 6, and a pressure relief valve 39 is arranged in the pipe port 3, The pressure relief valve 39 is connected to the processing plate 6 through a connecting rod 40. When the water flow pressure in the pipe port 3 pushes the pressure relief valve 39 to carry out water circulation, the axial movement of the pressure relief valve 39 pulls the processing plate 6 to move up and down. The sponge 8 is driven to absorb the water droplets 33 attached to the outer wall of the battery pack 7 during the alternation of cold and heat.

[0035] In this embodiment: a pressure relief valve 39 is provided in the pipe mouth 3. When the water flow in the pipe mouth 3 circulates, the water flo...

Abstract

The invention discloses a low-temperature preheating system for power battery packs for new energy vehicles, and relates to the technical field of low-temperature preheating systems for power battery packs for new energy vehicles. A low-temperature preheating system for power battery packs for new energy vehicles includes side plates , the side plate is connected with a cover plate and a bottom plate, the cover plate, the side plate and the bottom plate are all provided with pipe openings, and the cover plate, the side plate and the bottom plate are assembled to form a storage tank inside for placing the battery pack, The battery pack is provided with a second T-shaped slot, and a sponge is installed in the second T-shaped slot, and an adjustment component is connected to the sponge. The invention utilizes the sealing plate to drive the processing plate to stretch and shrink toward one side of the battery pack, so that the processing plate pulls the sponge and squeezes the sponge. After the sponge absorbs the water droplets attached to the surface of the battery pack, the squeezed sponge squeezes the water droplets that were originally absorbed. Press it out to ensure that the sponge is dry and can continuously absorb water droplets to ensure complete absorption of water droplets, making the device highly efficient in preheating and heating.

Description

technical field [0001] The invention relates to the technical field of a low-temperature preheating system for a power battery pack for a new energy vehicle, in particular to a low-temperature preheating system for a power battery pack for a new energy vehicle. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., and their exhaust emissions are relatively low. [0003] For pure electric vehicles and hybrid electric vehicles, the power battery is an indispensable part. When the temperature is low, the power battery enters the working state from a static state instantly. Due to the large instantaneous temperature difference before and after starting, the power battery itself will be damaged The existing low-temperature preheating system for power battery packs for new energy vehicles needs to use excess heat to ev...
