[2022 Green Mobility Awards] Green Mobility Award 'Choi Wooseok, Head of Hyundai Motor Electrification Test Center'

[Asia Economy Reporter Hyunseok Yoo] "Not only does the PE (Power Electric, motor·power conversion·battery) system for E-GMP (Electric-Global Modular Platform) offer high performance, but its modular design also allows efficient adaptation to various future electric vehicles of Hyundai Motor Group. Moreover, the consumer response in the market seems to have rewarded our efforts so far."

Choi Wooseok, Executive Director and Head of Hyundai Motor Electrification Testing Center, who received the Green Mobility Award (Minister of Trade, Industry and Energy Award) at the 2022 Korea Green Mobility Awards, said, "Since joining Hyundai Motor Group in 2003, I have worked with a sense of mission to realize more popularized electrified mobility, progressing from hybrid electric vehicles and plug-in hybrid electric vehicles to pure electric vehicles over 18 years."

Choi, who holds a Bachelor's degree in Mechanical Engineering from Pusan National University, a Master's degree from Wichita State University in Kansas, USA, and a Ph.D. from Texas A&M University, joined Hyundai Motor in 2003. He developed Hyundai Motor Group's proprietary hybrid system TMED (Transmission Mounted Electric Device), served as General Manager of Electric Vehicle and Hybrid Vehicle Development in 2015, and has been leading the Electrification Development Center (now Electrification Testing Center) since 2017.

Based on his experience at Hyundai Motor Group, he played a major role in developing the PE system for Hyundai's dedicated electric vehicle platform E-GMP. In particular, he led the development of a high-efficiency silicon carbide (SiC) motor system capable of 400V·800V multi-charging to fundamentally reduce the rapid charging time, a key market demand for electric vehicles.

Existing 800V high-voltage charging system electric vehicles required separate components to use the widely available 400V rapid charging infrastructure. However, the 400V·800V multi-charging motor system can use both ultra-fast chargers and existing rapid chargers without additional parts. Besides charging compatibility, the rapid charging time for high-voltage batteries was reduced by about 44%, from 32 minutes to 18 minutes. Executive Director Choi explained, "The system for Hyundai's dedicated electric vehicle platform E-GMP is based on an 800V high-voltage system, providing a high-efficiency motor system and fast charging speed that differentiate it from competitors' vehicles."
