In terms of where to put your charger in a garage: You want to be near the garage doors, preferably towards the left side of the car.
- Near the garage doors allows you the opportunity to reach the back of a car that's in the driveway (eg, a guest car.)
- If you have a two door garage, between the two doors is best. Assumes your only electric car (for now,
) will be parked in the right slot (looking into garage from outside).
- If you have a 1 door garage, place it on the left side (looking into garage from outside).
These choices will give you maximum options to charge cars - assuming you drive into the garage and not backing in.
Relative to your circuit breaker panel: I would recommend you prioritize location as indicated above, versus ease of installation - you want to live with the charger location for the next XX years... so, it is worth it to place it in an easy to use, ergonomic height.
