One of the biggest complaints about electric cars is their long charging times that cannot compare with refuelling speeds of gasoline-powered vehicles. Nyobolt, a British firm that produces ultra-fast-charging batteries, claims it has revolutionized battery technology and developed a battery pack that can fully charge in less than six minutes. The concept EV sports car boasts a 35-kilowatt-hour battery pack that can cover a range of approximately 155 miles (250 kilometers) on a single charge. Although the weight of the sports car has not been officially disclosed, Nyobolt hinted that it is closer to one tonne than two, indicating that the car weighs less than 3,307 pounds (1,500 kilograms).
