Why is it so difficult to design electric car/truck batteries that have the same range (about 300 miles) as gas powered vehicles?

It’s really the only reason I haven’t bought one, as I regularly travel across Pennsylvania from Pittsburgh to Philadelphia and especially in the wintertime I understand the range is even less because of the cold.

Combination of fuel energy density and motor efficiency. Electric motors in vehicles are close to (some exceed) 95% efficiency. Gas engines are lucky to make 35%. So electric motors are way better at turning fuel into motion (rather than heat and noise).

And they need to be. To store the energy in 1 litre of petrol requires almost 10kWh of battery. Those 24kWh nissan leafs manage to go ~80 miles on the equivalent of about 2L of petrol.
