The increasing number of Electric Vehicles (EVs) on the roads brought about the need for more charging stations, including DC fast charging stations and CHAdeMO-compliant fast charging stations.

DC fast charging stations provide vehicles with level-3 charging, enabling a 100-kilometer driving range in just 10 to 12 minutes. While level-2 chargers supply AC power to the battery (which is then converted to DC power by the on-board charger), level-3 fast chargers directly deliver DC power, which significantly improves charging time.

DC charging stations currently target three main power levels: ≤ 50 kW for city use, 150 kW for highways, and 350 kW for supercars/trucks/buses. DC fast chargers usually include 20 kW subunits and then stack them up to create a higher power DC charging system. The ≤ 50kW power level category for city use shows the biggest growth according to market studies.

ST's offer for DC fast charger designs

ST provides a range of power discretes including Silicon-Carbide (SiC) and silicon power MOSFETs, diodes and protection devices (TVS), and isolated gate drivers, as well as high-performance STM32 microcontrollers to contribute to the development of high-efficiency, high-power density DC fast charging stations.

Our CAN transceivers are designed to boost connection between an electric car and the charging pile, and the power line transceivers and programmable Bluetooth Low Energy System on Chips ensure fast connection between the charging pile and the user interface.
