How much battery drain is normal for a Tesla overnight?
1 Answers
Tesla typically consumes about 0.5% to 1.5% of its battery overnight. A full charge for a Tesla consumes approximately 100 kWh (for the Model S 100D variant). The official range of this model is 579 km, so the energy consumption per kilometer can be calculated as 100 kWh / 579 km = 0.173 kWh. Pure electric vehicles eliminate the need for a fuel tank, engine, transmission, cooling system, and exhaust system. Compared to the internal combustion engine powertrain of traditional vehicles, the cost of electric motors and controllers is lower, and pure electric vehicles have higher energy conversion efficiency. Since the energy source for electric vehicles—electricity—comes from large-scale power generation units, their efficiency is unmatched by small gasoline engines or even hybrid engines. Consequently, the operating costs of pure electric vehicles are decreasing. The downside of pure electric vehicles is that they alter the traditional lifestyle of car usage, requiring daily charging. The conventional habit for cars is refueling roughly once every one to two weeks. Additionally, each trip is limited to a few hundred kilometers in range.
