I have just bought an e-golf (great!). I intend only to use 3 pin wall socket charging as I only do low mileage (av 100 per week). The salesman suggested charging overnight on a cheap tariff and using a simple 3 pin timer plug/socket to switch it on and off at preset times. I'm a bit concerned that these timers aren't up to the job of a few hours throughput at 13A. Any views/recommendations?
