| 摘要： | Electric vehicles have been around for more than a century (just as long as petrol, in fact), so the driveline technology is well-developed. Many manufacturers are using technology already proven in city bus applications. As far as urban and medium-range transport goes, all-electric trucks are certainly well on the way there, with most mainstream OEMs testing pre-production vehicles in commercial use with customers. Long-haul maximum-weight remains the biggest challenge. Tesla claimed to have cracked that particular nut back in 2017 in a high-profile launch of its Class 8 (80,000-lb/36,300kg gross weight) semi which promised volume production and a network of dedicated chargers in place across North America by 2019. A range of 500 miles was projected, but no estimate of unladen weight was ever given. The truck's delayed market launch is now promised for this year. |
