Problems solved by technology

[0002] Electric vehicles are now driven by lithium-ion batteries, and lithium-ion battery cores may be damaged or fail when the temperature exceeds 55 degrees, and current electric vehicles generally use air-cooled or water-cooled methods to deal with the heat generated by battery modules. However, when the ambient temperature is higher than 30 degrees or exposed to sunlight for a period of time, the temperature of the battery system will rise rapidly to 45 to 50 degrees Celsius, sometimes even to 55 degrees Celsius. If the battery is not cooled in time and quickly, the battery will be damaged. However, the existing cooling methods can no longer meet the requirements of rapid cooling.

Embodiment Construction

[0014] From figure 1 It can be seen that the temperature-controlled vehicle lithium-ion battery module housing part of the present invention is composed of a bottom plate 1, side baffles 2 and 3, and an upper cover 4. A plurality of lithium battery cores 30 are housed in the housing, and each lithium battery One side of the core 30 is connected with a compressible rubber strip 31, and the other side of the lithium battery core is seated in a dustpan-shaped aluminum box 32 folded at 90 degrees on three sides, and a viscous heat-conducting silicone grease layer passes through the three sides. 33 is seamlessly bonded with the aluminum box 32, and the outside of the aluminum box 32 on the middle battery core is connected with the adhesive strip 31 fixed on the adjacent battery core 30.

[0015] From figure 2 , image 3 , Figure 4 It can be seen that the refrigerating part of the present invention is composed of interconnected semiconducting refrigerating sheets 10 and heat-co...

Abstract

The invention relates to a lithium ion battery module capable of automatically adjusting interior temperatures and belongs to the field of electric vehicle-mounted power supplies. The lithium ion battery module comprises a casing, a lithium ion battery pack and a refrigeration portion, a battery cell transmits heat to heat conducting aluminum plates on two sides of the battery cell through a dustpan type aluminum case, a semiconductor refrigeration sheet leads the heat out of the heat conducting aluminum plates to a radiating plate, and cooling water runs through the inside of the radiating plate and takes away the heat. A heat insulation plate is arranged between the radiating plate and the heat conducting aluminum plates and isolates the interior of a battery from the exterior of the battery, an opening which is of same size with the refrigeration sheet is opened on the radiating plate, and the refrigeration sheet is placed in the opening for finishing refrigerating (or heating) functions. The process is automatically achieved by the fact that electron thermo bulbs installed in the heat conducting aluminum plates control an electronic control system.
