5-34 Instruments and Controls
Delayed Departure Time: The
vehicle estimates the charging start
time considering the programmed
departure time for the current day
of the week. Charging begins at the
start time and is complete by the
departure time only if sufficient time
is allowed after the charge cord is
plugged in. The vehicle uses an
internal clock for programmable
charging, not the clock in the
center stack.
I n f o r ma t i o n P r o v i d e d b y :
Delayed Rate and Departure
Time: The vehicle estimates the
charging start time based on the
utility rate schedule, utility rate
preference, and the programmed
departure time for the current day of
the week. The vehicle will charge
during the least expensive rate
periods to achieve a full battery
charge by the departure time.
Electrical rate information from the
utility company for the charging
location is required for this mode.
