DC Fast Charging Station for Electric Vehicles

Renesas provides a DC fast charging station system solution for electric vehicles (EVs) that achieves high efficiency and high power. Shortening the charging time is essential for the spread of EVs; the DC fast charging station must follow the charging standards that support higher power and higher voltage.

System Benefits:

• High efficiency is achieved by using lower loss insulated-gate bipolar transistors (lower VCE sat). It is possible to use a cheap and compact cooling system, which contributes to cost reduction and miniaturization of the system.
• A small variation of the IGBT gate drive threshold (Vth) improves the unbalance in parallel connection and improves stability and safety.
• The combination of a Renesas microcontroller and power management IC can simplify the design of abnormality monitoring and diagnostic functions and minimize BOM costs.
• Renesas' gate driver IC has high output drive capability and can drive high-power power devices. It supports parallel driving to achieve high-power output while reducing BOM cost.
• By using automotive grade, high quality and high durability are also achieved, the best solution for DC fast charging station for EVs, which requires lower loss and high reliability.
