Power Electronics Systems (OBC-Based Integrated Solutions)
Power electronics systems are a vital part of commercial electric vehicle (EV) platforms, enabling efficient energy conversion, onboard charging, and power distribution across vehicle subsystems. Our OBC-based integrated solutions provide flexible and reliable power electronics configurations for buses, trucks, logistics vehicles, and specialized commercial EV applications. By offering both standalone and fully integrated systems, we help vehicle programs optimize space, simplify wiring, and improve overall system coordination.
Onboard chargers (OBC) are essential for converting AC grid power into DC energy to charge the vehicle’s battery pack efficiently. Depending on the vehicle architecture, programs may choose standalone OBC units or combined configurations integrated with DC-DC converters (DCDC) or power distribution units (PDU). Integrated solutions reduce the number of separate components, minimize wiring complexity, and improve packaging efficiency within limited vehicle spaces. This is particularly valuable for commercial vehicles where cabin, chassis, and underbody space are at a premium.
Standalone OBC units are available in multiple power ratings, including 3.3kW, 6.6kW, 11kW, and 20kW, allowing programs to select chargers that align with battery voltage, charging speed, and operational requirements. For programs requiring more compact and multifunctional solutions, we offer 2-in-1 systems combining OBC and DCDC converters, providing both charging capability and low-voltage power supply management from a single module. Advanced 3-in-1 configurations integrate OBC, DCDC, and PDU functions into a single assembly, further streamlining vehicle architecture, reducing component count, and improving reliability.
We support system-level configuration to ensure that power electronics solutions are correctly matched to battery systems, electric drives, and auxiliary subsystems. This includes guidance on voltage compatibility, communication protocols, thermal management requirements, and packaging considerations. Our goal is to deliver fully coordinated solutions that optimize energy efficiency, reduce project risk, and enhance long-term reliability.
