MAXON Telecom (CEO Kim Won-seok) announced on the 29th that it has successfully developed Korea’s first hybrid energy storage system (H-ESS) for electric vehicle charging stations, in collaboration with its technology partners.
The newly developed H-ESS is a dedicated solution for EV charging infrastructure, addressing key limitations such as power overload, fire risks, and high construction costs.
Conventional energy storage systems (ESS) often face challenges in EV charging applications, including excessive heat generation during repeated high-speed charge/discharge cycles, rapid performance degradation, and relatively short operational lifespan, leading to higher risks and operating costs.
MAXON Telecom’s H-ESS integrates high-performance capacitors with lithium-ion batteries optimized for ultra-fast charge and discharge cycles. This enables stable, simultaneous charging of multiple vehicles even during peak demand periods.
The system significantly minimizes heat generation during sudden load fluctuations, reducing fire risks while ensuring a lifespan that is 5 to 10 times longer than conventional ESS solutions. Its compact and modular design also reduces installation space requirements and infrastructure costs, improving overall efficiency.
The solution is designed for high-demand environments such as highway charging stations, electric bus depots, and large-scale urban charging hubs.
This development was carried out as part of a national initiative to enhance EV charging infrastructure. MAXON Telecom led the overall system development, including control systems and advanced temperature monitoring technologies.
CEO Kim Won-seok stated, “We will expand the application of this technology to high-performance sectors such as AI data centers and renewable energy-linked ESS solutions, while accelerating our expansion into global markets, particularly in North America and Europe.”
