Vehicle Performance in Extreme Ambient Temperatures
The high-voltage battery pack internal temperature and State of Charge (SoC) can affect performance. A vehicle may experience reduced performance or become inoperable if levels fall outside of a certain range.
The chart below details conditions that may cause reduced performance or vehicle shutdown when the vehicle is not connected to an EVSE charger and power supply.
NOTE
Battery pack internal temperature may differ from ambient temperature.
| Battery Pack Internal Temperature | State of Charge (SoC) | ||
|---|---|---|---|
| Less than 5% | Less than 15% | Greater than 15% | |
|
Below -22° F (-30° C) |
Vehicle will not operate. | Vehicle will not operate. | Vehicle will not operate. |
|
Greater
than -22° F (-30° C) |
Battery heaters inactive. Reduced performance. | Battery heaters* only active if battery temperature is below -4° F (-20° C). Reduced performance. | Allow several minutes for battery heaters* to warm up. Normal performance. |
|
Greater
than 50° F (10° C) |
Reduced performance. | Reduced performance likely. | Normal performance. |
|
Greater
than 131° F (55° C) |
Reduced performance. | Reduced performance. | Reduced performance. |
|
Greater
than 140° F (60° C) |
Vehicle will not operate. | Vehicle will not operate. | Vehicle will not operate. |
| *Battery pack heaters will not activate unless the key switch is in the ON position when vehicle is not connected to an EVSE charger and power supply. | |||
