[CES 2024] LS Electric-EVsys Collaborate on EV Charging... "Reducing Weight by Half"

Improving Solid State Transformer Efficiency
Securing ESS-Linked DC Large-Capacity Chargers
"Exploring Overseas Expansion Using EVsys Global Certification"

LS Electric announced on the 11th that it signed a memorandum of understanding (MOU) on electric vehicle charging infrastructure with EVSIS, a subsidiary of Lotte Information & Communication specializing in electric vehicle charging platforms, at 'CES 2024,' the world's largest electronics and IT exhibition held in Las Vegas, USA, on the 10th (local time). They will collaborate on the Solid State Transformer (SST) and microgrid-based electric vehicle charging infrastructure business.

About 30 representatives from both companies, including Kim Jong-woo, President and COO of LS Electric Global CIC, and Oh Young-sik, CEO of EVSIS, attended the signing ceremony. The two companies agreed to develop next-generation electric vehicle charging infrastructure technology based on a DC Grid composed of SST.

LS Electric plans to build a renewable energy DC power grid, including energy storage systems (ESS), using its own SST. By combining this with EVSIS's next-generation DC-type high-capacity electric vehicle chargers and charging platforms, they aim to secure next-generation electric vehicle charging infrastructure technology at the microgrid level.

LS Electric's SST is not just equipment that performs electrical voltage transformation like a conventional transformer. It applies power semiconductors to perform voltage transformation as well as DC-AC conversion. It offers higher charging and conversion efficiency compared to conventional transformers. There is no need to install separate power conversion devices. DC electric vehicle chargers use batteries, which differ from general power grids that use AC. Using SST instead of separate power conversion devices at electric vehicle charging stations can reduce installation area by up to 40% and weight by more than half.

EVSIS's charging platform has localized the entire charging system with its self-developed high-efficiency, high-capacity DC-DC power modules. It is evaluated to have differentiation in reliability and maintenance compared to other companies' chargers that use foreign modules. Chargers of medium-speed or higher account for about 70% or more. This gives it higher market competitiveness compared to other companies' portfolios that mainly focus on slow chargers.

An LS Electric official said, "We will not only establish a technological foundation to lead the electric vehicle charging infrastructure market but also expand various new businesses such as microgrids, distributed energy, and complex stations linked to charging infrastructure. Since EVSIS recently completed certification for all charger products to enter the global market, we plan to jointly enter overseas markets after domestic demonstration."
