500W Onboard Battery Charger for 2-Wheeler EV

The global electric two-wheeler market is growing rapidly, driven by increasing environmental concerns, rising fuel costs, and government incentives. As adoption accelerates, the demand for reliable and efficient charging solutions becomes critical. Onboard chargers, like this 500W platform from Renesas, eliminate dependence on specialized infrastructure by enabling direct charging from standard AC outlets, offering unparalleled user convenience.

This platform leverages Renesas GaN devices for high efficiency and is optimized for universal input AC/DC battery charger designs with output power levels of up to 500W. Its architecture includes two advanced power stages: Power Factor Correction (PFC) which ensures efficient AC to DC conversion, and LLC Stage which delivers over 95% peak efficiency in DC to DC conversion.

System Benefits:

• Exceptional efficiency with 650V GaN FETs, reducing power losses for faster charging and enhanced reliability.
• Integrated MCU enables CAN communication with the end device for reporting critical information, including battery health, load connection/disconnection events, and other essential housekeeping functions.
