Am I missing a timer function on the car that simply starts charging at a pre-programmed time?
Yes, there is a function in the car's charging menu that can be used to set the start time indirectly. The timer function allows you specify a time that the car will be fully charged and then the car will start charging based on the capacity of the EVSE it is plugged into and its current SOC. For example, you can set the timer so that the car will be fully charged at 8AM. The car will then calculate when to start charging based on the current SOC and the amount of power available from the EVSE. AFAIK, there is no way to stop the charging before 100% so unless you unplug the car at 5AM or charge to 100% every night, this feature won't be very helpful.
If you have the know-how to construct a device with adequate contactors and a relay and timer to drive them then that would work. Or you could sell the OEM EVSE you have and buy another EVSE that has better controls. OpenEVSE is one source that can do this but I'm sure there are many more.
