dfolz@sbcglobal.net Posted September 7, 2015 at 09:39 PM Report Share Posted September 7, 2015 at 09:39 PM I really enjoy the quiet surge of power pulling away from a stop in my Fusion Energi using only the battery. Doing that in a gas car is a waste of gas, so my question is - is it inefficient to accelerate hard using battery only? Up to 25mph or so where air resistance is not a factor.

dfolz@sbcglobal.net Posted September 7, 2015 at 11:05 PM Author Report Share Posted September 7, 2015 at 11:05 PM My apologies - my above post belongs in Energy Driving Tips & TricksI'm not an engineer and so don't fully grasp EV Dynamics Physics Experiment by larryh - more of a thesis than a mere post.But I think larryh answers my above simplistic question about battery efficiency. As I suspected, the harder you press the accelerator, the less efficient the car becomes. Sigh. Quote Link to comment Share on other sites More sharing options...
larryh Posted September 7, 2015 at 11:12 PM Report Share Posted September 7, 2015 at 11:12 PM It takes more energy the faster you drive. If you accelerate fast, your average speed will be faster (you get to your destination faster) than if you accelerate slowly. Approximately 90% of the extra energy consumed by faster acceleration is due to this factor. The remaining 10% is due purely to motor efficiency. The motor isn't quite as efficient during hard acceleration. Hybridbear 1 Quote Link to comment Share on other sites More sharing options...
