The charging timer software, with a start and stop time, does not allow you to block out peak hours. For example, my peak hours are 12 noon to 6 PM Mon-Fri, with no peak hours on Sat and Sun. I cannot insert a 6PM start time and still be able to charge before 12noon. Or, if I select start at midnight and end at noon, the car will not charge from 6PM to midnight! The timer software should allow you to apply a charge/no-charge schedule to each hour of the day and apply that schedule to selected days of the week.
