Car manufacturers have invested heavily in electric cars due to the need to reduce carbon emissions, but sales remain low. In 2019, about 2 percent of new vehicle sales in the world were electric vehicles. Jason Fenske of Engineering clarified why EV adoption could stagnate.
According to Fenske, the key issue is that batteries are not as energy-dense as petrol. This means that a certain amount of energy is required with batteries rather than good ancient dinosaur juice. According to Fenske, a gallon of gasoline corresponds to an energy of 33,7 kilowatt-hours. And one gallon contains more energy than the whole Nissan Leaf battery pack.
But, in general, electric cars are better than petrol cars, Fenske pointed out. According to the Toyota, the 2ZR-FXE motor is one of the most powerful in-house combustion motors in manufacture, at some 40%. According to Fenske, however, most electric motors can operate consistently at 90% output.
However, other factors largely negate the difference in quality, says Fenske. Differences in driving conditions and cold ambient conditions will reduce electric cars ‘ performance, he said.
Another challenge is the extra weight and size of a battery pack in contrast to a fuel tank. To get enough energy from an e-car, more battery cells must be added, which take up space and increase the weight of a vehicle, Fenske said.
According to Fenske, this is not so much an issue for EPVs as for other types of electric vehicles. For example, the weight of semi-cars is regulated. So the amount of freight it can hold could be severely restricted if enough of the electric half truck is taken away, Fenske said.
This didn’t stop companies trying to develop semi-electric trucks. Tesla said that its Semi is 500 milles long and the truck has drawn attention from companies such as Budweiser and Walmart. It should be remembered that early electric semi-trucks are usually used between dedicated terminals on shorter runs to make sure they’re never too far from a charging station.
The density of energy could also affect the many currently emerging electric pick-up trucks. Towing limits performance inherently, but this is not typically an issue for petrol and diesel pickup trucks. Even if the fuel economy is getting worse with the towing, the drivers will not suffer from large fuel tanks. Towing can, however, decrease the range sharply with an electric vehicle.
