Parameters
----------
uid : int
Unique of the car agent.
model : ChargingModel
The base charging model defined as base for the simulation.
clock : Clock
The Handle to the global clock object.
house_agent : HouseAgent
The house_agent assigned to this car_agent.
company : Company
The company where this agent is working.
location_road_manager : LocationRoadManager
Handle to the location road manager.
car_model_manager : CarModelManager
The object handling all car models created in ChargingModel class.
whereabouts_manager : WhereaboutsManager
The object handling all whereabouts created in ChargingModel class.
calendar_planer: CalendarPlaner
The object handling the creation of calendars across the
simulation.
parameters: Parameters
Provides external parameters.
Parameters handed by Parameter class
----------
departure_condition : string
Ensures that car never runs out of power midway. Can take three
different values:
ROUND_TRIP = SOC needs to allow for completing next route
twice (back and forth) PLUS reserve_range.
ONE_WAY_TRIP = SOC needs to allow for completing next route
once PLUS reserve_range.
NEXT_NODE = SOC needs to allow for reaching the next node
PLUS reserve_range.
reserve_range : int
Range the car needs to be able drive without charging in km.
reserve_speed : int
Velocity assumed car is driving maximum once it hits reserve in
km/h.
queuing_condition : string
Allows to choose if the car owner is actively trying to charge its
car in case all chargers are blocked by the time of arrival. That
is, return later once a charger is available or just leave the car
not charging in case there is no charger available by the time of
arrival. Can take two values:
ALWAYS = Que everytime a destination is reached.
WHEN_NEEDED = Only if the departure criteria is not satisfied.
Returns
-------
None.
