Anpin specializes in providing solutions for thermal management of power battery.

In recent years, Shenzhen Anpin Silicone Material Co., Ltd. has been dedicated to providing solutions for the thermal management of power batteries, aiming to better address the heating and cooling issues of electric vehicle batteries. With the frequent occurrence of electric vehicle fires and explosions caused by lithium-ion battery "thermal runaway" reported in the media, thermal management has become a research hotspot at this stage. How to effectively ensure the heat dissipation and safety of power lithium-ion batteries has become a sword of Damocles hanging over the heads of vehicle manufacturers and power battery companies.

I. Battery thermal management is very important; neither too cold nor too hot is acceptable.

China has a vast territory, a wide range of latitudes, significant differences in distance from the sea, varying terrain heights, diverse terrain types, and mountain ranges, resulting in a variety of temperature and precipitation combinations and significant climatic differences. Can electric vehicles drive normally and safely in extreme cold and heat? This is largely related to the power battery on board.

The properties of power batteries are greatly affected by temperature factors, with discharge efficiency changing with temperature, thereby affecting the performance of electric vehicles. Currently, the operating temperature range of lithium-ion batteries is wide, from -20°C to 60°C.

(1) In low-temperature environments, the driving range of electric vehicles will significantly decrease, and in severe cases, more than half of the range can be lost, making it difficult to charge the "cold" battery.

(2) In high-temperature situations, without an appropriate cooling solution, there will be significant temperature differences within the battery pack, affecting the consistency of battery cells and leading to a series of subsequent issues. The most serious of these is battery overcharging causing "thermal runaway," which can lead to electric vehicle fires and explosions.

II. How can we avoid these problems?

Manufacturers need to manage the thermal management of batteries; both heating and cooling of batteries are important.

(1) The former mainly involves cold starting, driving range, and power performance;

(2) The latter involves the warranty life of the battery system and the safety of the vehicle.

Only by keeping the battery pack temperature within a reasonable range (neither too low nor too high) can the battery perform better in terms of performance and lifespan, ensuring the driving safety of electric vehicles.

From the perspective of heat transfer media, thermal management systems can be divided into air cooling, liquid cooling, and phase change heat storage thermal management. Different systems have different effects. To solve the problems of difficult battery charging at low temperatures and low capacity, most manufacturers will adopt strategies of special materials for insulation. To prevent safety hazards caused by high temperatures, thermal management materials can be used, which can effectively solve the problems of battery heating and cooling. Anpin has products in this category.

The development of the power battery market is very rapid, with a year-on-year growth of 238% in shipments. As a solution provider in the silicone industry, Anpin has provided a variety of solutions for the thermal management of power batteries to avoid safety accidents in electric vehicles.

In the future, the development prospects of electric vehicles will become even broader, as will power batteries. A suitable and stable temperature is crucial for power batteries, and there is no need to overemphasize this point.

In summary, good thermal management materials can make the battery's working environment tend towards "warm in winter and cool in summer," adding an extra layer of security to electric vehicles; with safety, we can pursue more long-term development.
