Macan tests its Porsche portable DCFC charger for Helium Electric

Porsche’s latest innovation in electric vehicle (EV) technology brings a portable DC fast charger (DCFC) that packs a punch. In which this portable charging trailer with a capacity of 2.1 megawatt per hour can charge up to 320 kilowatts. Recently showcased by Kyle on the Out of Spec YouTube channel the charger was put to the test in the French Riviera, powering the beautiful new Porsche Macan Electric as well as showcasing its capabilities.

Porsche’s Turbo Charging Portable DCFC has been operational since 2019, serving as a charging solution for automakers. And Porsche has deployed seven such charging trailers across Europe, making them an excellent solution for a variety of charging scenarios, including prototype testing, marketing and test drive events and track days.

Although similar technologies have existed since 2010, Porsche’s charging system is remarkably innovative. Most other systems have much smaller capacities. But the trailer on display weighs up to 70,000 pounds, and has a battery capacity of 2.1 megawatts and supports 3.2 megawatts of load. It has ten plugs on the unit, each capable of delivering 320 kW, with the battery pack capable of supporting ~400 amp peak discharge.

In the given example, the trailer is plugged into the grid to recharge the battery pack. However, the trailer’s Island Mode allows it to operate entirely on battery power. When connected directly to power, a series of heavy duty gates from the power source to the trailers, designed with special plugs and a converter, provides a 5-pin, 3-phase red plug with both neutral and ground.

Each trailer’s massive battery pack can be recharged from the grid in about four hours. Once fully charged from power, the AC to DC converter bypasses the battery pack to charge the car directly, acting as a pass-through to the AC to DC converter.

When in Island Mode, the trailer can also balance the charge levels across all battery packs. However, this is a somewhat inefficient process because there is no DC-to-DC connection between them, requiring two conversions from DC to AC and then back to DC. Therefore, they try to avoid it whenever possible.

But the system also includes a lot of other fascinating technical details, so if you’re interested in batteries and EV charging technologies, watching the full video is a must.
