Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] Refer to attached figure 1 As shown, a layered soft-packed lithium-ion battery module is composed of a plurality of plate-shaped basic units arranged side by side, wherein the plate-shaped basic unit includes a soft-packed lithium-ion battery 1, an outer frame 4, a cooling plate 3, an elastic Vibration pad 2 and other parts. The outer frame 4 is cast from insulating material, the heat dissipation plate 3 is embedded in the outer frame 4, the elastic damping pad 2 is placed on the heat dissipation plate 3, and the heat dissipation plate 3, the outer frame 4 and the elastic vibration damping pad 2 form a concave structure. space, and the battery 1 lies flat in this space. The plate-shaped basic unit can be expanded laterally, and can also be multi-layer laminated to achieve expansion in the thickness direction.

[0037] The outer frame 4 can easi...

Abstract

The invention relates to a layer type soft package lithium ion battery module and a battery pack thereof. The layer type soft package lithium ion battery module comprises a plurality of basic units, and each basic unit comprises a soft package lithium ion power battery, an outer frame, a heat dissipating plate, an elastic anti-vibration pad and other parts. According to the battery pack formed by stacking a plurality of layer type soft package lithium ion battery modules based on the expected capacity, by means of conducting plate connection, parallel connection or series connection of the battery modules can be achieved. The single-layer module is formed by the basic units in an expanding mode. The number of the basic units of the single-layer module can be adjusted according to the needs of various objective conditions. The battery pack can be flexibly expanded according to space provided by a vehicle, and arrangement is convenient. By means of the soft package lithium ion battery module, the number of elements for achieving electric connection can be obviously reduced, and expanding is convenient.

Description

technical field [0001] The invention relates to a lithium-ion battery module, in particular to a layered battery module composed of soft-packed lithium-ion batteries and a battery pack thereof. Background technique [0002] The development of energy-saving and new energy vehicles has become an inevitable choice for my country's energy strategy. According to the development plan, the current focus is to promote the industrialization of pure electric vehicles and plug-in hybrid vehicles. In my country, electric vehicles used to use lead-acid batteries as power batteries, but lead-acid batteries have low energy density and will have a negative impact on the environment, making manufacturers have to find alternatives; hybrid vehicles used to use nickel-metal hydride batteries, but Ni-MH batteries have low energy density and are not suitable for plug-in hybrid vehicles. Lithium-ion batteries have become the first choice for pure electric vehicles and plug-in hybrid vehicles becau...
