Let's say I build a battery operated car that is set to drive forward, but I put it right in front of a wall. It attempts to drive forward, but instead it just pushes into the wall and nothing moves. The battery will continue to drain, and thus potential energy is being lost, yet no work is happening. The car and the wall do not move. Let's assume that the car is able to push the wall with a consistent force of 1 Newton.

If I know how long the car has been pushing (let's say for one hour), can I calculate the potential energy loss based on the fact that the car has been pushing with 1 Newton, for one hour? The work is zero because if W=fd, the distance is 0, so the work is zero. Yet, there definitely is a loss of potential energy in the battery. How can I calculate that?
