I am trying to build a vampire proof laptop charger. Vampire proof meaning that the charger will not consume power when it is not needed.
The simplest way to do this is to unplug the charger. However the charger is often in hard to reach places, and unplugging it means climbing over furniture. So many people will leave it plugged in for convenience. The solution to this would be to cut the primary induction coil and wire a switch across the gap, so that when you plug in the charger the laptop pushes in the switch and completes the circuit.
A more energy efficient way of doing this would to also put a timer and a check circuit on the charger. The check circuit will monitor the amperage in the secondary induction coil, to determine when the laptop is at full charge. So that when the laptop reached full-charge the check circuit will break the primary induction coil. The timer will kick in and reestablish the coil within a curtain about of time. Then the process will repeat.
The problem I need some way to check the amperage of the secondary induction coil. Does anyone know how I can do this?
Or any other advice is more than welcome, thanks
