Programmable Charging (PLUG-IN Only)
Important Information About Portable Electric Vehicle Charging

  • Charging an electric vehicle can stress a building’s electrical system more than a typical household appliance.
  • Before you plug into any electrical outlet, have a qualified electrician inspect and verify the electrical system (electrical outlet, wiring, junctions, and protection devices) for heavy-duty service at a 12 amp continuous load.
  • Electrical outlets may wear out with normal usage or be damaged over time, making them unsuitable for electric vehicle charging.
  • Check the electrical outlet/plug while charging and discontinue use if the electrical outlet/plug is hot, then have the electrical outlet serviced by a qualified electrician.
  • When outdoors, plug into an electrical outlet that is weatherproof while in use.
  • Mount the charging cord to reduce strain on the electrical outlet/plug.

Danger
Improper use of portable electric vehicle charge cords may cause a fire, electrical shock, or burns, and may result in damage to property, serious injury, or death.

  • Do not use extension cords, multi-outlet power strips, splitters, grounding adaptors, surge protectors, or similar devices.
  • Do not use an electrical outlet that is worn or damaged, or will not hold the plug firmly in place.
  • Do not use an electrical outlet that is not properly grounded.
  • Do not use an electrical outlet that is on a circuit with other electrical loads.

See the charge cord user guide.

Programmable Charge Modes
This vehicle has three programmable charge modes. To view the current charge mode status in the infotainment display, touch[in the infotainment display and then touch CHARGING at the bottom of the display.
The Charge Start and Charge Complete time estimates are also
displayed on the screen. These estimates are most accurate when the vehicle is plugged in and in moderate temperature conditions. Also, to get an accurate time estimate, the vehicle uses an internal clock for programmable charging, not the clock in the infotainment display.

Charge Mode Status2018 Cadillac CT6-Display Warning Messages-fig 2
Immediately: The vehicle starts charging as soon as it is connected to an electrical outlet. See Plug-In Charging (PLUG-IN Only) 0 292.2018 Cadillac CT6-Display Warning Messages-fig 3

Delay Charge Based on 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.2018 Cadillac CT6-Display Warning Messages-fig 4

Delay (Electric 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.
Also, if the selected electric rate settings result in a very long charge completion time, the vehicle will start charging immediately upon plug-in. For example, if the electric rate table is set up with all “Peak” rates and the rate preference is to charge during
“Off-Peak” rates only, then the vehicle will start charging immediately upon plug-in.

Charge Limit Selection
The Charge Limit Preference setting allows the customer to select their vehicle’s charge level so it matches the capability of their charging location. If the vehicle consistently stops charging after plugging in, or if a circuit breaker continues to trip, reducing to a lower Charge Limit Preference may resolve the issue.2018 Cadillac CT6-Display Warning Messages-fig 5
The Charge Limit Preference should be configured to match the electrical current rating for the electrical outlet that the charge cord is connected to. The Charge Limit Preference
settings are:

  • Maximum: Limits AC to 12 amps
  • Reduced: Limits AC to 8 amps

Exact current levels may vary from the values shown in this manual. Check the vehicle for the current available levels.
The Charge Limit Preference setting can be changed at any time while the infotainment display is operable.
For some vehicles, the Charge Limit Preference must be updated before the vehicle is charged and the Charge Limit Preference will reset to a default value when the vehicle is shifted from P (Park).

Warning
Using a charge level that exceeds the electrical circuit or electrical outlet capacity may start a fire or damage the electrical circuit. Use the lowest charge level until a qualified electrician inspects the electrical circuit capacity. Use the lowest charge level if the electrical circuit or electrical outlet capacity is not known.

Charge Mode Selection
From the Charge Mode Status screen, touch Charge Mode.2018 Cadillac CT6-Display Warning Messages-fig 6

  • Electric Rate Schedule
  • Charge Rate Preference

Earliest or Latest Completion Time
If the vehicle calculates that the cost would be the same for various charge modes based on the charge rates selected, select to finish the charge at the earliest possible time or the latest possible time. Use the Earliest setting to charge as soon as possible if there is a planned departure before the scheduled departure time. Use the Latest setting to optimize energy usage.

Charge Rate Preference Selection
From the Charge Rate Information screen, touch Charge Rate Preference.2018 Cadillac CT6-Display Warning Messages-fig 9
Touch one of the following options to select the Charge Rate Preference:

  • Charge during Peak, Mid-Peak, and Off-Peak Rates: The vehicle can charge during any rate period to satisfy the next planned departure time. However, it will select when to charge to minimize the total cost of the charge.
  • Charge during Mid-Peak and Off-Peak Rates: The vehicle will charge during Off-Peak and/or Mid-Peak rate periods only and will select when to charge to minimize the total cost of the charge.
  • Charge during Off-Peak Rates: The vehicle will only charge during Off-Peak rate periods.

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. For example, if the vehicle is plugged in for only one hour before the departure time, and the battery is completely discharged, the vehicle will not be fully charged by the departure time regardless of the rate selection.
Also, if the selected electric rate settings result in a very long charge completion time, the vehicle will start charging immediately upon plug-in. For example, if the electric rate table is set up with all Peak rates and the rate preference is to charge during Off-Peak rates only, then the vehicle will start charging immediately upon plug-in.

Electric Rate Plan Selection
Electric rates, or cost per unit, may vary based on time, weekday/weekend, and season. During the day when the electricity demand is high, the rates are usually higher and called Peak rates. At night when the electricity demand is low, the rates are usually lower and called Off-Peak rates. In some areas, a Mid-Peak rate is offered.
