Futuristic or Impossible? Tesla’s Proposed Semi and Roadster Battery Capabilities
Tesla has announced two new truck models: the Semi and the Roadster. The models will reportedly be powered by batteries the likes of which have never been seen before, and experts are pessimistic about the potential they promise.
Here are four of the outstanding claims that make the Semi and Roadster batteries models seem unreal:
• Semi’s 500-Mile Range
Tesla has promised that the Semi’s battery will pack enough energy to travel 500 miles while hauling 80,000 pounds. This would require an 800 kilowatt-hour battery that would cost over $100,000 – the truck will go for $180,000. Experts expect that battery prices will have fallen by the time the trucks hit the road.
• Roadster’s 620-Mile Range
To last for 620 miles on a single charge, the Roadster’s battery will have to be at least twice as heavy and as big as Tesla’s biggest battery. This may pose a problem not only with the battery’s development but also with the engineering required to fit it into the truck. Experts, however, think that Tesla can install two batteries to overcome these obstacles.
• 7 Cents Per Kilowatt Hour
Electricity is currently valued at about $1 per kilowatt. As such, Tesla would incur massive losses by selling it for 7 cents. However, experts theorize that Tesla may build chargers in truck terminals as prices here are subsidized. The company may also deploy its stationery batteries to store energy and hence avoid causing spikes in power to other entities.
• 30-Minutes, 400-Mile Charging
Tesla’s best charger yet, the “supercharger”, is capable of charging a 180-mile range battery in 30 minutes. To provide 400-mile worth of power is a similar period would require a charger with an output of 1,200 kilowatt.
What to Expect
Tesla has made big claims before and delivered. The new trucks will not be released until 2020, and there are many ways that the company could deliver on its promises.
