With the low current needed for a trickle charger, just wire it to a
cigarette lighter plug and drape the wire across the steering wheel.  It
would be hard to drive off without noticing it.

Another solution would be to wire a 3 wire 1/4" phone plug to it and a jack
to the car in an appropriate location where it will unplug if you drive
away.  Connect the 3rd terminal to get power from the car's jack and use it
as a safety circuit to shut off the charger if it is not connected.

A lot easier, more reliable, and cheaper than monitoring the voltage and
calling your cell phone.
