Battery Operating Temperature
The vehicle will not operate if one or more batteries has an internal temperature below 14° F (-10° C).
When not in use, park the vehicle and connect the battery charger. See page 64. When the vehicle is connected to the charger, batteries are maintained at full performance operating temperature in addition to receiving a full charge.
If the vehicle is not connected to the charger while parked in cold weather, battery temperatures may drop below 14° F (-10° C). If this occurs, connect the vehicle to the charger to increase battery temperature before operating. When batteries are extremely cold, battery temperature will increase by approximately 17°-27° F (10°-15° C) per hour while charging.
Turning the key on will also activate the battery heaters, but battery power will be used quickly. This method is not recommended if SOC is low.
Operating and Charging Performance | ||
---|---|---|
Conditon | Battery Temperature | Description |
Low Temperature Operation | Below 14° F (-10° C) | The vehicle will not operate. |
14° F (-10° C) | The vehicle will operate. If the state of charge (SOC) is also low (below 55%), vehicle performance may be diminished until a higher temperature is reached. | |
Low Temperature Charging | 50° to -20° F (10° to -30° C) | The modules must first warm the batteries. During this warming process, the charger charges at a reduced rate. Full rate charging occurs when battery temperature reaches 50° F (10° C). |
Below -20° F (-30° C) | The charger cannot warm or charge the batteries. Move the vehicle to a warmer location if possible, or transport the vehicle to your dealer for service. | |
High Temperature Operation | 14° to 120° F (-10° to 50° C) | With an adequate SOC, the vehicle will operate at full performance. |
120° to 140° F (50° to 60° C) | With an adequate SOC, the vehicle will operate at reduced performance. | |
Above 140° F (60° C) | The vehicle will not operate. | |
High Temperature Charging | 14° to 113° F (-10° to 45° C) | The charger will charge batteries at the full charging rate. |
113° to 131° F (45° to 55° C) | The charger will charge at a reduced charging rate, but only up to 80% SOC. |
