No. Energy conversions are never 100 percent efficient, so every time we convert one form of energy to another, we lose some of that energy. Hybrids and EVs recapture some of their energy back into the batteries through regenerative braking.
What happens if you run out of charge in a Tesla?
If your energy usage is significantly higher than expected while you are close to the last SuperCharger, the Tesla will direct you to return to it to charge further. If you are approaching your destination and low on range, the Tesla will recommend a specific speed reduction to ensure you reach your destination.
