Evcharger Schedule

The evcharger object can be put on a schedule to control when it is at home, work, or on a trip. This can be done by using a schedule for the p_go_home and p_go_work properties (only control when it is at home or work) or by using the demand_profile property.

Example

module residential;
module tape;

clock {
	timezone PST+8PDT;
	timestamp '2001-07-10 00:00:00';
	stoptime  '2001-07-18 00:00:00'; 
};

object house {
	object evcharger {
		object recorder {
			file charge.csv;
			property charge;
			interval 600;
		};
	};				
}
