White Paper Overview
As electric vehicle adoption grows, charging infrastructure must deliver higher power, shorter charging times, and support a broader range of battery voltages. This white paper presents a modular 100 kW bidirectional DC fast charger demonstration design for grid-to-vehicle and vehicle-to-grid energy flow, with an output range suited to high-voltage EV, eBus, and eTruck platforms.The design combines a scalable power architecture with measured performance data from charging and inverter operation. It also highlights the thermal and control considerations identified during testing.
Review the full white paper to see how bidirectional power flow, high-voltage operation, and efficiency come together in a practical charging system.
