Chaebee, an operator of electric vehicle fast-charging infrastructure, announced on the 12th that it has installed a 1.2-megawatt (MW)-class ultra-fast charging system (MCS) at the Korea Electrotechnology Research Institute’s Ansan branch and begun integrated demonstration tests.
The MCS is a charging technology that supplies high-output power to large commercial vehicles, such as electric trucks and electric buses, which have battery capacities seven to 10 times larger than those of standard electric passenger cars. It is considered a key technology for expanding the adoption of commercial electric vehicles by shortening charging times for large-capacity batteries.
Chaebee is participating as the lead institution in the “Development and Demonstration of AI-Based High-Efficiency MCS and Ultra-Fast Charging Systems” project, which has been underway with government support since 2024. The company is carrying out system development and demonstration work together with 11 participating institutions.
In this demonstration, Chaebee will integrate the power bank, a power supply device developed separately, and the MCS dispenser, which delivers power to vehicles, into a single system to verify performance, safety, and reliability.
Chaebee plans to inspect high-output continuous charging performance and power quality over a total of 2,000 hours by early next year. Based on the demonstration results, the company aims to improve the system and advance the charging technology for application to large electric trucks and buses.
Choi Young-hoon, CEO of Chaebee, said, “We will expand our charging technology expertise and infrastructure operation capabilities, which have been accumulated with a focus on passenger electric vehicles, into the large-scale mobility sector.”
Meanwhile, the MCS dispenser developed by Chaebee received an Innovation Award in the Vehicle Technology and Advanced Mobility category at “CES 2026” and a Consumer Choice Award in the Charging Infrastructure Manufacturing category at “EV Awards 2026.”
