Giant Mining Trucks and Buses Are Smashing Electric Vehicle Records

Giant Mining Trucks and Buses Are Smashing Electric Vehicle Records”

The largest battery pack in any volume electric auto sold today is 100 kwh in top-end versions of the Tesla Model S hatchback sedan and Model X crossover utility vehicle.

The Schluckspecht-E, however, was an aerodynamic lightweight single-seat auto, not a 40-foot brick-shaped mass transit bus.

Proterra's Catalyst E2 max electric bus drove over 1,100 miles on a single charge under test conditions, a new world record for any electric vehicle.

Battery-electric powertrains offer an excellent way to eliminate emissions in urban and suburban areas previously generated by the diesel engines used in transit buses and other commercial vehicles, some of which may cover 1 million miles in a typical service life.

The test was part publicity stunt and part demonstration of the gains made in electric vehicle technology. The top-end Tesla battery pack is 100 kilowatt hours. No one would be choosing between the two, of course.

Beyond pure EVs, several other outfits are developing or selling hybrid medium- and heavy-duty EVs: Wrightspeed has its hybrid garbage trucks, Toyota is testing hydrogen fuel cell trucks at the Port of Long Beach, and Nikola and Bosch just announced plans to team up on hydrogen fuel cell long-haulers. One is the Chinese company BYD, which operates a bus and truck assembly plant in Lancaster. The bus was driven (without any passengers on board) around the Navistar Proving Grounds in New Carlisle, Indiana. The first E2 series buses are due to reach Los Angeles streets later in 2017, so it might not be long before you can witness this longevity first-hand. The model now being sold has an upper range of 350 miles.

A typical Proterra bus costs around $750,000 compared with roughly $500,000 for a typical diesel bus, chief commercial officer Matt Horton said in an interview. The bus maker has begun assembling battery packs at a new factory in Burlingame, California. "We're entering an era where electric vehicles are simply better than internal combustion engines on range".

Lithium-ion cells for the battery were provided by Korean maker LG Chem, which also provides cells for battery-electric cars to numerous automakers globally.

Proterra now sells a Catalyst E2 bus that can drive 350 miles on a single charge.
