Samsung SDI solidified its position in the electric vehicle battery industry by winning the Global Electric Vehicle Association (GEAN) Award at the opening ceremony of the 9th International Electric Vehicle Expo (IEVE) held on the 3rd.

Samsung SDI announced that Vice Chairman Jeon Young-hyun received the World Electric Vehicle Association Award at the opening ceremony of the 9th International Electric Vehicle Expo (IEVE), which was held from the 3rd to the 6th at the Jeju International Convention Center (ICC JEJU) and Jungmun Tourist Complex, and Vice President Jang Rae-hyeok, head of the Medium and Large Battery Business Division Development Division, gave a keynote speech.

As the opening ceremony keynote speaker, Vice President Jang Rae-hyeok presented on the topic of 'EV Ultra Fast Charging Barriers and Enablers.'

Vice President Jang said that the biggest issue regarding electric vehicles is the battery issue, and that battery efficiency is a challenge for the commercialization of electric vehicles.

Vice President Jang introduced the concept of rapid charging for electric vehicles, categorizing it into vehicle/battery level, rate issues, and environmental issues, and the limitations and technologies and methods to overcome them.

Vice President Jang said that the existing limitations include: △Willingness to pay additional amount for fast charging, △Peak time conversion and ESS utilization plan, and △Battery technology (8 vehicles).He said that the electric vehicle charging problem can be solved by considering factors such as 00 volt migration, use of ultra-fast charging cathode materials, and ultra-fast, fast, and slow batch management.

Research shows that people want to charge their electric vehicles quickly and use them for a long time, just like they can fill up a tank of gasoline in 12 seconds at a gas station. However, this raises concerns about charging costs and the air pollution caused by EPA environmental regulations.

To improve the efficiency of electric vehicle batteries, it is promising to install cooling devices and migrate to 800 volts as a way to drastically reduce charging times, and SiC MOSFETs are utilized for this.

Ultimately, to achieve battery efficiency, continuous research and development is necessary, including improving rapid charging performance through improvements in cathode materials and methods, and Samsung SDI has expressed its ambition to achieve efficiency through appropriate mechanisms.

Meanwhile, at this event, Samsung SDI's 'PRiMX' was displayed at the booth, and Samsung SDI's diverse battery lineup, including products currently in mass production and Gen. 6 batteries under development, were on display.

BMW iX was also on display, attracting the attention of visitors. The BMW iX is a high-performance vehicle equipped with Samsung SDI's Gen. 5 battery, with a driving range of 630 km (WLTP standard) on a single charge and a 0-100 km/h acceleration time of 4.6 seconds.

In addition, Korea's first electric ATV (All Terrain Vehicle: 4-wheel motorcycle) and electric scooter equipped with Samsung SDI's cylindrical batteries, as well as a replaceable battery pack and charging station, were also exhibited.

“Samsung SDI has been continuously striving to lead the electric vehicle market based on differentiated battery technology and the best quality,” said Vice President Son Michael, head of the strategic marketing team at Samsung SDI’s Medium and Large-Sized Battery Business Division. “This exhibition will be an opportunity to see Samsung SDI’s technology and vision.”
