Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] see figure 1 , the entire battery module group is mainly composed of: an upper cover 1, a battery module group 2, a temperature-controlled fluid cooling device 3, a heat conduction patch 4, a lower frame 5, and connecting bolts 6.

[0026] The specific structures of the main components upper cover 1, temperature-controlled fluid cooling device 3 and lower frame 5 are as follows:

[0027] 1. Top cover (such as figure 2 , image 3 shown):

[0028] The upper cover has a rectangular frame structure, and four countersunk mounting and fixing holes 1-a are evenly distributed at both ends of the frame.

[0029] There are three rectangular bosses 1-b in the middle of the upper cover, and a "U"-shaped groove is opened on the top, which is used for installing bezels or fixing brackets for the battery module.

[0030] The four corners of the upper cover of the battery modu...

Abstract

The invention provides a temperature-controllable power battery module group, comprising an upper cover, a battery module group, a temperature-controlled fluid heat radiating device, a heat-conducting patch and a lower framework. The battery module group is arranged on the lower framework, the upper cover covers on the upside of the battery module group, the lower framework is connected with the upper cover through bolts, and the battery module group is fixed between the upper cover and the lower framework; the temperature-controlled fluid heat radiating device is arranged at a bottom surface of the battery module group; and the heat-conducting patch is attached between the temperature-controlled fluid heat radiating device and the battery module group. According to the invention, temperature-controlled media is injected into the temperature-controlled fluid heat radiating device in the entire battery module so as to realize the heat transfer for the lower surface of a battery module and balance the temperature of each battery monomer, and thus the effect of making the power batteries capable of working at a proper temperature stably is achieved, the service lives of the power batteries are prolonged, and the working safety of the power batteries is guaranteed. The module is fixed by combining the upper cover and the lower framework, and the temperature-controllable power battery module group has the characteristics of simpler structure, low manufacture cost, high strength in fixing a battery pack, convenience for mounting and dismounting.

Description

technical field [0001] The invention relates to a temperature adjustment method, module composition and installation and fixing of a power battery module group device. Background technique [0002] Electric vehicles have developed rapidly in recent years, and their safety is the most valued by people. However, during use, the performance and safety of the power battery of an electric vehicle are greatly affected by the external environment temperature. Therefore, the power battery should reasonably consider its heat dissipation and balanced control of temperature. Contents of the invention [0003] Based on this background, the present invention proposes a temperature-controllable power battery module group to achieve three purposes: Realize the temperature regulation of the battery module; Simplify the structure of the battery module; It is convenient to install and fix the battery module. [0004] Technical scheme of the present invention is as follows: [0005]...
