In this tech talk, Steven had the pleasure of discussing Hydrogen Powered Portable EV Charging with Jiří Vršínský, Project Manager at DEVINN.
Learn about Hydrogen Powered Portable EV Charging
Steven Oji and Jiří Vršínský discuss innovative solutions for hydrogen, battery, and charging development. They discuss the need for mobile EV charging solutions in areas where there are blind spots or limitations with the AC grid. The components of a charging station, such as the communication unit, power electronics, and fuel cells are also highlighted. The topic of power management, which involves managing the battery SOC, vehicle SOC, DC DC conversions, fuel cells, hydrogen storage, and everything else involved in charging an EV is deeply discussed.
Electric vehicles can be charged by connecting AC power, which is then converted to DC by the vehicle and used to charge the battery. In most cases today, DC power is connected to the CCS circuit in the vehicle, which is the standard every electric vehicle uses right now. There is also a communication interface between the vehicle and the charging station, which tells the vehicle how much power, current, and voltage the charger can provide. The vehicle then tells the charging station how much power, current, and voltage it requires. Power electronics are used to convert AC or DC power to the power required by the vehicle, which can be an AC-DC converter or a DC-DC converter.
The vehicle is charged with hydrogen, a fuel cell is added, and a DC-DC converter is used to control the fuel cell. A battery is also involved in this process to take care of the peaks and provide a buffer for sudden stops in the charging session. The power management system used in charging stations takes care of the battery SOC, vehicle SOC, DC-DC conversions, fuel cell, hydrogen storage, and other components.
