Problems solved by technology

[0003] The invention provides a lithium battery fixed frame with a temperature control board, which effectively solves the temperature control problem of the existing soft-pack lithium battery and effectively solves the bottleneck of low heat exchange efficiency of the soft-pack lithium battery module through external air or liquid Restricted, it significantly optimizes the soft-pack lithium battery to quickly achieve its own temperature balance, ensuring that it works at the best ambient temperature at all times, thereby improving the service life and maintenance cycle of the soft-pack lithium battery pack. Through a reasonable structural layout, the The module assembly is more compact and reasonable, which reduces the module space occupied by the temperature control system and improves the volume-to-energy ratio of the battery module

Embodiment Construction

[0019] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0020] Such as Figure 1-2 As shown, a lithium battery fixed frame. The fixed frame is composed of a hollow cubic plastic frame 1, which is injection-molded with plastic materials such as flame-retardant pp plastic or flame-retardant DMC, and a temperature control plate 4 with a heating resistance wire 2;

[0021] Specifically, the temperature control board 4 is pre-embedded in the middle of the frame 1 when the frame 1 is injection molded, so that the temperature control board and the frame are closely and firmly combined;

[0022] Further, see Figure 4 ,, the temperature control board 4 divides the frame 1 into two accommodation chambers, the temperature contro...

Abstract

The invention discloses a fixed border of a lithium battery. The fixed border comprises a frame and a temperature control board, wherein the frame is a hollow cube frame; the temperature control boardis arranged in the middle of the frame and divides the frame into at least one accommodating cavity; each accommodating cavity is used for arranging the lithium battery; two sides of the temperaturecontrol board extend out of through holes in two sides of the frame and form folded edges; the folded edges are used for being in contact with an external coolant circulating plate or carrying out heat exchange with cold air; a stretching groove is arranged in the temperature control board; a heating resistance wire is embedded into the stretching groove and is insulated and fixed through an insulating heat-conduction material; and the heating resistance wire is provided with an energizing interface at one end, free of a battery core tab, of the frame.

Description

technical field [0001] The invention relates to a lithium battery fixing device, in particular to a lithium battery fixing frame and a lithium battery module. Background technique [0002] Soft-pack lithium-ion power batteries have been widely used in the field of new energy pure electric vehicles and hybrid new energy vehicles. The application of this field has prompted the use of lithium battery packs to adapt to a wider temperature range - from -20 to 50 ℃. Due to the limited chemical properties of lithium batteries, the best working environment temperature is 20-40°C. This requires that when assembling lithium battery modules, it is necessary to consider how to balance the temperature of lithium battery modules through the temperature control system to ensure that lithium batteries The module can meet the conditions of use no matter in the environment of high temperature or low temperature, and at the same time, the temperature rise of the lithium battery can be control...
