Megawatt Charging System (MCS): Testing Report from CharIN & NREL

The CharIN Megawatt Charging System (MCS) Task Force is undertaking efforts to develop a new high-power charging standard for heavy-duty vehicle electrification.

The National Renewable Energy Laboratory (NREL), in Golden CO, hosted a CharIN MCS evaluation event from 25 May 2023 through 24 January 2024 to evaluate proprietary prototype designs from multiple manufacturers. Industry representatives Amphenol, Daimler, Stäubli, and TE Connectivity provided hardware for testing and evaluation.

The National Renewable Energy Laboratory’s (NREL) recent testing of the Megawatt Charging System (MCS) marks a pivotal moment in electric vehicle technology, particularly due to the collaborative efforts with the CharIN members. This partnership underscores the commitment to interoperability and the future of sustainable transportation. The comprehensive testing conducted by NREL, in conjunction with CharIN, is a testament to the power of collaboration in innovation. Together, they are setting the stage for a new era of electric trucks capable of charging at unprecedented speeds, thanks to the MCS standard.

Produced under the direction of CharIN e.V. and the California Energy Commission by the National Renewable Energy Laboratory (NREL) under TSA-19-16406 and FIA-15-01813, this summary report documents aggregated and anonymized CharIN Megawatt Charging System (MCS) device performance data collected by NREL from 25 May 2023 through 24 January 2024.

The success of these tests is a beacon for the industry, signaling the readiness for a transition to more efficient and environmentally friendly freight transport solutions.
