E-car range: why nobody needs a 1000 km e-car

One of the central arguments of e-car skeptics is the insufficient range of electric cars. Sure: Anyone who has a tank with fuel for 800 kilometers is not afraid of range. But visionary e-cars help to rethink. Therefore, the planned Mercedes Vision EQXX with a range of 1000 km is a great idea to dispel fears, but such an XXL range is not sensible and necessary. On the one hand, I want to see the driver who actually sits behind the wheel for ten or eleven hours straight – without peeing or taking any other breaks. Nobody does that! And when the car comes to a standstill, you should be able to recharge, that would be much more important.

So the problem of range is not one of the small batteries, but one of the few quick charging stations on highways where electricity has so far been too expensive. Huge battery packs, which are necessary for a long range, do not make sense either. For two reasons: Batteries are the most expensive component in electric vehicles, so small batteries mean cheaper purchase prices for electric cars. In addition, a large battery adds massive weight. That may be acceptable with the Porsche Taycan, its powerful 93.4 kW / h energy package weighs a whopping 650 kilos. Much too much for everyday cars, because the weight exacerbates the average energy consumption, and it takes more effort to accelerate. It increases axle load and wear on tires and chassis.

Better to have lighter e-cars than those with a longer range

Why are the batteries still so heavy? Their energy density is rather low, perhaps it will be greater in the next generation of batteries. With lighter batteries, however, the engineers should rather reduce the overall weight of the cars than increase the range. Because lower energy consumption protects the environment. By the way: The Mercedes EQXX should consume less than 10 / kWh per 100 km.

The electricity should be in the grid, not in e-cars

In my opinion, electric cars should only carry as much electricity as they foreseeably need. A range of around 500 km allows daily commuting over 70 to 80 km easily for a whole working week without having to charge once. Let’s leave the electricity in the grid, transport it like no heavy batteries through the area! My theory: Anyone who wants a 1000 km range before switching to an electric car does not want to drive electrically at all. But rather more combustion.
