"EV Charging Station Costs Down"... LS Materials Develops First Hybrid ESS

Overcoming Power Overload and Safety Limitations
Enhancing Efficiency at Highway Rest Areas and More
5 to 10 Times Longer Lifespan Compared to Conventional ESS

LS Materials and LS Cable & System have developed the nation's first Hybrid Energy Storage System (H-ESS) dedicated to electric vehicle charging stations.

On May 29, LS Materials announced that, in collaboration with LS Cable & System, it has developed the first H-ESS in Korea specifically for electric vehicle charging stations. The H-ESS is a dedicated solution designed to address the limitations of power overload, fire risk, and infrastructure construction costs at EV charging stations.

Conventional ESS units have the drawback of rapid heat generation and performance degradation during repeated rapid charging and discharging, as well as a shorter lifespan, which makes them risky and costly to operate at EV charging stations. LS Materials explained that the H-ESS combines capacitors optimized for high-speed charging and discharging with lithium-ion batteries, enabling stable charging of multiple vehicles even during peak hours.

LS Materials stated, "We have minimized heat generation even during rapid load changes, reducing the risk of fire, and achieved a lifespan 5 to 10 times longer than conventional ESS. Furthermore, the miniaturization of the ESS allows for reduced installation area and costs compared to existing systems, enhancing infrastructure construction efficiency." The company emphasized that the system is particularly suitable for efficient operation in environments with concentrated demand for rapid charging, such as highway rest areas, electric bus depots, and urban multi-purpose charging stations.

This development was carried out as a national project under the Ministry of Trade, Industry and Energy to advance EV charging infrastructure, with LS Materials overseeing the entire system and LS Cable & System developing the control and temperature monitoring technologies.

Hong Youngho, CEO of LS Materials, stated, "We plan to expand applications to other fields requiring high-speed response, such as artificial intelligence (AI) data centers and ESS linked to renewable energy, and will also accelerate our entry into the global market, focusing on North America and Europe."
