Imagine a gasoline-powered car and an EV, both requiring 100 kWh for a journey. Assume that the conversion from chemical to mechanical energy is 25% efficient for the gasoline car and 90% efficient for the electric car. The state-of-the-art lithium-ion batteries have an energy density close to 250 Wh/kg, which is still relatively small compared to 12,900 Wh/kg for gasoline. What is the calculated weight of fuel required for the gasoline-powered car and what is the weight of the EV battery?

Answer:
Imagine a gasoline-powered car and an Ev, both requiring 100 kWh for a journey. Assume that the conversion from chemical to mechanical energy is 25% efficient for the gasoline car and 90% efficient for the electric car. The state-of-the-art lithium-ion batteries have an energy density close to 250 Wh/kg, which is still relatively small compared to 12,900 Wh/kg for gasoline. What is the calculated weight of fuel required for the gasoline-powered car and what is the weight of the EV battery? Gasoline weight - 7.75 kg and EV battery weight – 400 kg Gasoline weight - 31 kg and EV battery weight 444 kg Gasoline weight - 7.75 kg and EV battery weight - 444 kg Gasoline weight 400 kg and EV battery weight → 31 kg
