Here is one of the hidden issues related to EVs, weight!
Yet it is one of the key reasons users report the elegant EV ride, they have more mass per cubic centimetre of car than just about anything else on the road. When you want something to move smoothly in a straight line, you can't beat inertia and kinetic energy!
It's pretty lucky those EVs have heaps of torque isn't it?
Quote:An official with the US Dept Tranport, Jennifer Homendy, raised the issue in a speech in Washington to the Transportation Research Board. She noted, by way of example, that an electric GMC Hummer weighs about 9,000 pounds (4,000 kilograms), with a battery pack that alone is 2,900 pounds (1,300 kilograms)—roughly the entire weight of a typical Honda Civic.End users do not realise, but the weight of a battery required to match a tank of fuel can be as high as 10x the mass of that tank of fuel. In a typical 4-door sedan configuration an 80L tank holds about 75kg of fuel for 650km on a typical use cycle, for the same range the battery would have to weigh at least 650kg or more subject to the type of battery technology.
"I'm concerned about the increased risk of severe injury and death for all road users from heavier curb weights and increasing size, power, and performance of vehicles on our roads, including electric vehicles," Homendy said in remarks prepared for the group.
The extra weight that EVs typically carry stems from the outsize mass of their batteries. To achieve 300 or more miles (480 or more kilometers) of range per charge from an EV, batteries have to weigh thousands of pounds.
