Coal plants are quite efficient as is the conversion of electricity to mechanical energy in an electric motor.

You haven't factored in the loss while the electricity passes through power cables from the plant through the grid.

‘You haven’t factored in the loss while the electricity passes through power cables from the plant through the grid.’

About 5%.

Normally you are charging at night when power would be produced locally and grid losses are minimal. Moreoever deep cycle battery efficiencies are 85-95%. Electic motor efficiencies are over 90%. Also, you haven't factored in the cost of getting and refining oil.

Electric cars are quite efficient. That is not the problem. The problem is initial capital cost, battery lifetime and range.
