Charging Status
The following illustration is provided for demonstration purposes only and may vary slightly
depending on the software version and market region of your Model S.
1. Charging status information. For example, if Model S is charging, it displays the time
remaining until fully charged at the currently selected charge level. When a charging session
has been scheduled, it displays when charging starts.
2. Total estimated driving distance (or energy) available. Instead of driving distance as shown
here, you can display the percentage of battery energy remaining by touching Controls >
Settings > Units & Format > Energy & Charging.
Note: A portion of the battery image may appear blue. This indicates that a small portion of
the energy stored in the battery is not available because the battery is cold. This is normal and
no reason for concern. When the battery warms up, the blue portion no longer displays.
3. Charging rate per hour.
4. Estimated increase in driving distance (or energy) achieved so far in this charging session.
Instead of driving distance as illustrated above, you can display the amount of energy gained
by touching Controls > Settings > Units & Format > Energy & Charging.
5. Current being supplied/current available from the connected power supply (see Changing
Charge Settings on page 135).
6. Voltage being supplied by the charge cable.
Note: If Model S is charging and detects unexpected fluctuations in input power, the charging
current is automatically reduced by 25%. For example, a 40 amp current is reduced to 30 amps.
This automatic current reduction increases robustness and safety in situations when a problem
exists outside of Model S and its charging electronics. For example, a home wiring system,
receptacle, adapter or cord is unable to meet its rated current capacity. As a precaution, when
Model S automatically reduces a location's current, it saves the reduced current at the charging
location. Although you can manually increase it, Tesla recommends charging at the lower current
until the underlying problem is resolved and the charging location can provide consistent power.
