Embodiment Construction
[0022] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and specific conditions.
[0023] A method for preparing a new energy power battery pack provided by the present invention comprises the following steps:
[0024] (1) Treatment of metal materials to be welded:
[0025] Polish the surface of the aluminum plate 1-1 and the steel punching plate 1-2, so that the joint surface of the two is flat, smooth and pollution-free, and the thickness of the aluminum plate 1-1 and the steel punching plate 1-2 is not less than 0.5 mm, the aluminum plate 1-1 is pure aluminum or aluminum alloy, the steel punching plate 1-2 is carbon steel or stainless steel, and the holes on the steel punching plate 1-2 are uniformly arranged in a circular, regular hexagonal or square shape;
[0026] (2) Welding:
[0027] The aluminum plate 1-1 and the steel punched plate 1-2 are welded by conventional explosive welding, l...

Abstract
The invention relates to a new energy power battery pack preparation method. A battery pack and a module end plate are included. An aluminum steel cooling partition plate is a U-type aluminum steel composite plate formed when an aluminum plate and a steel punching plate embedded in the aluminum plate are welded; positive and negative leads of a soft-packed core are upwardly placed in a U-type groove; heating films are wound between and at two ends of aluminum steel cooling partition plates; the lower part of the aluminum steel cooling partition plate is provided with a cooling way; a liquid coolant is introduced to the cooling way; the battery pack is formed; the circumference and the bottom of the battery pack are provided with heat insulation layers; and the module end plate is arrangedoutside the heat insulation layer. The anti-deformation ability is good, the weight is light and good heat dissipation is achieved; the material state does not change greatly; the service life of thebattery pack is prolonged; resources are greatly saved; energy conservation and environmental protection are achieved; and social and economic benefits are good.
Description
technical field [0001] The invention relates to a battery pack, in particular to a method for preparing a new energy power battery pack. Background technique [0002] Since the 1990s, green, low-carbon and sustainable development has become the main goal of the development of the energy field. Conventional fossil energy is facing many problems such as energy depletion, environmental degradation, and low energy conversion rate, which seriously affect human life and production needs. In order to get rid of dependence on fossil energy and improve the environment, many carbon-emitting countries in the world have turned their goals to electricity. The direction of replacing fossil energy. As a conventional energy source, electricity has two advantages. One is the high energy conversion rate of power plants, and the other is that the proportion of clean energy power generation in power generation is increasing day by day. [0003] With the improvement of national living standard...
