Embodiment Construction

[0051] The embodiments of the integrated battery box and its box body in the present invention will now be described with reference to the accompanying drawings.

[0052] The integrated battery box includes a box body, and a battery module capable of charging and discharging is arranged in the box body. The battery module is formed by arranging a plurality of battery cells. The box body of the battery box is also integrated to heat the battery module. Or a cold plate for cooling. The cold plate includes a plate body that fits the bottom surface of the battery box. The plate body is equipped with temperature-adjustable elements, such as cold pipes, heat pipes or heating fins. The cold plate is integrated In the box of the battery box, the integration degree of the whole battery system is directly improved. An insulation layer is provided between the cold plate and the box. The insulation layer can isolate the heat transfer between the cold plate and the box. In the vertical direct...

Abstract

The invention provides an integrated battery box and a box body thereof, which can solve the problem of low energy density of the battery box in the prior art. The integrated battery box in the invention comprises a box body and a battery module arranged in the box body, wherein the box body comprises a heat insulation layer and a cold plate which are arranged in the box body, the heat insulationlayer and the cold plate are sequentially arranged on the bottom wall of the box body, and the box body and the cold plate are both bonded with the heat insulation layer, or the cold plate and the heat insulation layer are fixed on the bottom wall of the box body through fasteners. Through the two assembly modes, the use of parts in the battery box can be reduced, so that the weight and the volumeof the battery box are reduced, and the energy density of the battery box is improved.

Description

Technical field [0001] The invention relates to the technical field of power batteries, in particular to an integrated battery box and a box body thereof. Background technique [0002] With the continuous advancement of power battery technology, the application of power battery systems in the automotive field has become more and more extensive. With the development of technology, electric vehicles have higher and higher performance requirements for power battery systems. In the process of high-rate charging and driving of electric vehicles, the heating of the battery causes the temperature of the battery and the battery box to continue to rise, leading to the charging alarm / current limit of the power system, which will cause the charging time to be longer, the output power is reduced, and the battery heats up The temperature of the battery and battery box is too high, which shortens the life of the power system. The temperature rise of the battery box has become an important fa...
