LS Materials Develops First Hybrid ESS for Electric Vehicle Charging Stations in Korea

[Financial News] LS Materials announced on the 29th that it has developed the first hybrid energy storage device (H-ESS) exclusively for electric vehicle charging stations in collaboration with LS Cable.
The newly developed H-ESS is a dedicated solution that can solve the limitations of power overload, fire risk, and infrastructure construction costs at electric vehicle charging stations. Existing ESSs have the disadvantage of rapid heat generation and performance degradation during repetitive rapid charging and discharging, and a short lifespan, making them risky and costly to operate when used at electric vehicle charging stations. LS Materials explained that they implemented an H-ESS that can stably charge multiple vehicles even during peak hours by combining capacitors and lithium-ion batteries specialized for high-speed charging and discharging. It minimizes heat generation even with rapid load changes, reducing fire risk, and has secured a lifespan 5 to 10 times longer than existing ESSs. The miniaturization of the ESS is possible, reducing both installation area and cost compared to existing facilities, thereby increasing infrastructure construction efficiency.
This development was promoted as a national project for the advancement of electric vehicle charging infrastructure by the Ministry of Trade, Industry and Energy. LS Materials oversaw the entire system, and LS Cable developed control and temperature monitoring technology. Hong Young-ho, CEO of LS Materials, said, "We will expand applications to fields requiring fast response, such as AI data centers and renewable energy-linked ESS, and will also actively target the global market, focusing on North America and Europe."
