What are the core competencies of electric car?

In the market for high-performance electric vehicles (EVs), the ability to efficiently regulate the temperature of motors and batteries has emerged as a new crux of competition. Japanese companies, including Denso (DENSO), are expanding the practical application of new systems that utilize refrigerants. An American corporation Tesla, which is currently leading the worldwide market for electric vehicles that are purely powered by electricity, is also focusing on the development of thermal control technology.

Tesla is at the forefront of the industry with its developed equipment system Independently, which uses the "Octovalve " component to cool the entire vehicle. The race to develop pure electric vehicles is continuing to escalate.

"Practicalization will be realized in 2025, and the charging time will be shortened to 1/3,"

 Yu Ofune, the chief technology development section 1 of Denso Thermal Management System Development Department, said confidently in his speech. The lecture was hosted by Gifu Prefecture, and the theme was "Seminar on Next-Generation Automobiles." The thermal management system of the battery electric vehicle released by Denso responded enthusiastically of participating parts manufacturers and metalworking enterprise operators.

In addition, Denso uses sensors to detect the high-temperature areas of the battery and let refrigerant flows to these areas preferentially to avoid temperature differences. By maintaining the same temperature, battery deterioration is inhibited and can extend 20% of the battery’s lifetime. Not only mentioned above, it also can use refrigerant to cool as well as provide electricity during the charging time, which can shorten one-third of the charging time. Denso has also developed its own "car brain", which is used to manage these precise control units, as known as ECU (Electronic Control Unit). Denso's advantage is that it has well experience in both engine and transmission cooling technology and air conditioning components," says Yoh confidently.
