Problems solved by technology

However, due to the increase in the length of the large module, the temperature uniformity in the length direction of the module is poor during cooling or heating. At present, the commonly used method for uniform temperature of the module is to optimize the design of the flow channel of the liquid cooling system

Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, the first feature being "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below" the first feature below the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the level of the first feature is smaller than that of the second feature.

Abstract

The invention discloses a uniform-temperature battery module. The battery module comprises a liquid cooling plate, a first end plate and a second end plate. A water inlet is formed in one end of the liquid cooling plate, a water outlet is formed in the other end of the liquid cooling plate, the first end plate is close to the water inlet, the second end plate is close to the water outlet, multiplecells are arranged between the first end plate and the second end plate, the first end plate is spaced from the liquid cooling plate, and the second end plate. The first end plate, close to the waterinlet of the liquid cooling plate, in the uniform-temperature battery module is not in contact with the liquid cooling plate. The second end plate close to the water outlet of the liquid cooling plate is contacted with the liquid cooling plate. Therefore, the temperature of the second end plate is also adjusted by the liquid cooling plate, the second end plate close to the water outlet of the liquid cooling plate exerts an additional cooling or heat preservation effect on the adjacent battery cell, the adverse effect caused by the fact that the battery cell is far away from the water inlet ismade up, the temperature difference between the battery cells is reduced, the battery module is in a better working state, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a temperature equalizing battery module. Background technique [0002] With the wide application of power batteries, people have higher requirements for the energy density, cruising range and safety performance of the battery system. The design of large modules can efficiently use the limited system space to achieve structural layout optimization and high safety. A new direction for group development. However, due to the increase in the length of the large module, the temperature uniformity in the length direction of the module is poor during cooling or heating. At present, the commonly used method for uniform temperature of the module is to optimize the design of the flow channel of the liquid cooling system. [0003] In the liquid cooling system, the outlet water temperature is higher than the inlet water temperature during cooling, and the cell temperature near the water ou...
