R6 Carbon battery.Those core technologies of Korean electric vehicles that cannot be ignored

　　At the 28th World Electric Vehicle Conference (EVS28), known as the "Electric Olympics", Korean companies demonstrated their strong technical strength at home. LG Chem, Hyundai MOBIS, etc. all exhibited their core key components of electric vehicles and battery products, and has formed a complete set of solutions. In contrast, China still needs to strengthen its overall strength in terms of practical technology for core components.

　　Those mature core components

　　LG Chem exhibited its core components e-PT electric drive device (drive motor, inverter, reducer), and electric vehicle thermal management system. Hyundai MOBIS showcases the latest environmentally friendly drive systems, control systems, fuel cell system devices and technologies.

　　Hyundai MOBIS and LG Chem have complete product lines of motors, batteries, electronic controls, etc. In comparison, only BYD in China can match it. Most companies either make batteries or motors, basically all of them are single From this perspective, the overall competitive level of domestic new energy vehicle core components is relatively behind South Korea.

　　The battery thermal management systems of the two companies currently include water-cooling and air-cooling systems. The air-cooling systems are equipped with axial flow fans, which dissipate heat better. A large amount of air flow can take away the heat. Without this device, Let the battery dissipate heat naturally, then there is a risk of excessive heat accumulation. The water-cooling system is a heat sink with a battery chip in the middle and a heat sink. When superimposed in this way, each heat sink has a very small water pipe, which takes away the heat like a blood vessel. The temperature is controlled very low. Easily catch fire. This water cooling technology is already a mature product. Therefore, Korean companies are already one step ahead when it comes to battery packs.
