Comemso’s Megawatt charging system: 1500kWh battery charging in just 20-30mins?

Comemso’s EV and EVSE test equipment company can now provide a Megawatt charging system (MCS) which can handle up to 1500kW charging, Automotive Powertrain Technology International (APTI) reported. 

The company’s advanced new platform is engineered on the existing CCS (Combo 1 and Combo 2), NACS, CHAdeMO, and GB/T DC and AC standards.

Kiriakos Athanasas, CEO of Comemso said, “Megawatt charging is more than just high power – it requires addressing new sets of challenges, from cooling mechanisms to cable design, and from specialized infrastructure to precise data measurement. Our team has worked closely with suppliers and dedicated intensive workshop sessions to master these complexities, ensuring our solution will deliver reliable results under real-world conditions,” the report by APTI added.

Although all the specifications of the charging technology have yet to be released, in general, a Megawatt charging system can completely charge a 1000kW battery in just 20 to 30 minutes. Until now, the technology faced a heating problem caused by the continuous flow of high-voltage current. However, according to the report, the Comemso system resolves such thermal issues and successfully addresses the system's smooth interoperability with international high-power charging standards. The MCS’s cooled cable technology is built to withstand continuous high-power EVSE and EV testing.

Additionally, because of its scalability, the platform makes room for the future MCS communication core, guaranteeing its future-proofness and flexibility in response to changing needs and new EV protocols.

Comemso has developed this new technology of operating high-current via cooling and cabling by working in coordination with various suppliers.

By collaborating with suppliers, Comemso has refined its cooling and cabling approach for high-current operation. This flexibility enables test labs and OEMs to implement bespoke solutions including climate chamber applications. 

Citing Anita Athanasas, CCO, APTI reported, “This isn’t just a single project – it’s the groundwork for a new era in EV charging, and we’re excited to enable our customers to ride this wave of innovation.”
