Application of B25615A7656J101 in Electric Vehicle Charging Stations

Filtration Technical Requirements for DC Charging Stations

Electric vehicle DC charging stations need to convert AC grid power to DC power for car battery charging. The power quality during this process directly affects charging efficiency and battery life. Charging stations have high power and power density, generating complex ripple components, placing high requirements on filter capacitor ripple current bearing capacity. At the same time, charging stations are mostly installed outdoors and need to withstand sunlight, rain, and temperature changes.
