Most people put small heating pads under the cells of the battery pack allowing for as small as 300 watts of heating pad to heat a pack in just a few hours, as little as half an inch of foam is then used to insulate the batteries allowing them to stay warm for many hours due to their great mass.
For EV battery heating, this type of heating can increase your watt hours per mile even after counting the energy used in heating the batteries, I doubt that a heater that is just under the batteries would give the same kind of gain over unheated batteries.
I like the idea of a smart control for controlling when the heater comes on, something that taps in to the calender of your smart phone and heats it up before you have to go some place would be slick, but a simple timer also works great.
I haven't been able to get the plug out that my block heater threads in to, but when I do I would like to install an inlet with a cover either in my bumper or fender so I don't have a cord end hanging out, for a while I was waiting on new parts for my electric car and was plugging the charger right in to an extension cord instead of the inlet that is on the side of the car and it was annoying, much easier to plug and unplug from when one side is firmly mounted, it would also of course allow for a heater in the cabin to be triggered at the same time with the same cord.
