While many automakers are focusing on small electric cars as a way to kickstart the EV revolution, Spains Opbrid thinks heavy duty trucks and buses are the way to go. Their innovative Trůkbaar system, which can recharge a heavy-duty EV’s battery in as little as six minutes using an adjustable height charger, says Gizmag.
Using four contact points and a super-high DC charging system, the Trůkbaar can deliver up to 650 kW, allowing for a larger battery pack to be recharged in just minutes. A trial system in Gothenburg, Sweden using a Volvo electric bus can give the vehicle 4.5 miles of driving range in just four or five minutes of charging. That’s not a lot of range, I’ll grant you, but the system allows chargers to be spread out along a typical bus or truck route, and can be hidden into the street scape rather than jutting out as this big ugly mechanical thing.
It’s an innovative way to keep the high costs of big battery electric buses down. BYD and Proterra think the long-term savings of their huge battery-powered buses make the upfront cost worth it. But not every municipality can afford to splurge on a $1.5 million electric bus. A smaller battery means a lower cost, and even though the charging system isn’t like cheap either, once installed it can service a wide fleet of electric municipal vehicles, including garbage trucks and postal vans, as well as the aforementioned buses. The system can adjust
Other cities, like Chicago, can afford to spend $650,000 for an electric garbage truck that goes 60 miles per charge. For smaller cities or clusters of towns, the Trůkbaar might be a more affordable alternative to a fleet of long range EVs.
