Electric vehicles are cool. They have instant acceleration and they leave no fossil fuel detritus in their wake. But charging them can be a pain int the neck. EV charging today involves many different standards. There are multiple power levels and several different plugs found at EV charging stations. Different cars charge at different rates. Add in charging capability for a welter of digital devices and a person today needs to carry around a Swiss army knife-like collection of charging cords and adapters to get through the day.
New EV Charging System
Continental says it has a better idea. Its AllCharge system builds on the components that are already built in to an electric vehicle — especially the inverter that already converts AC to DC and vice versa — to solve the connectivity issues. The company says those components already have the ability to function as a charging system, so why not put them to work? The system will be shown to the public for the first time at the Continental Tech Show this month. It will also be featured at the Frankfurt auto show in Germany in September.
Any vehicle equipped with the AllCharge system will be able to use any EV charging station operating on up to 800 volts. It will support charging power of up to 350 kW. “What was always lacking up until now was some sort of universal solution capable of working with any type of charging station,” says Dr. Martin Brüll, the lead engineer responsible for the the new charging system. “Such a universal solution is now available in the form of AllCharge.”
“With 350 kW DC charging, five minutes charging time provides approximately 150 km of driving range – a good indication of our charging system’s true potential,” says Dr. Brüll. “No matter how quickly the infrastructure develops in future, a vehicle with AllCharge technology will always be able to make the most of the selected charging station’s capacity.”
