USING THE VOLTA SYSTEM IN HOT AND COLD
TEMPERATURES
Refer to Temperature Limits on page 33 for details on the hot and cold
temperature operating limits.
Monitor your SOC gauge flashcodes or any indicators on your touchscreen to
assist in hot or cold climate operation.
High Temperature Operation
The Energy Storage Pack is designed with passive cooling. The BMS shuts down
the pack or prevents charging at elevated temperatures to allow the pack to
cool.
The Volta System charges normally and distributes power normally up to 116°F
(47°C). At or above 116°F (47°C), the Battery Management System (BMS) prevents
charging. At or above 134°F (57°C) the BMS shuts down the system.
To protect the pack, avoid using or storing the pack at or above 134°F (57°C).
Storage of the energy storage pack at elevated temperatures is not recom-
mended, as it will reduce the lifetime and capacity of the pack.
Cold Temperature Operation
The Volta System is capable of powering electrical systems below freezing
temperatures. However, if the Energy Storage Pack temperature is too low, the
system does not charge.
For system operation in cold
environments, and to maintain the
Energy Storage Pack at charge-ac-
cepting temperatures, the pack
may be equipped with heating
pads. Or, these heating pads are
available for purchase from Volta.
The internal heating system
operates automatically, as needed,
assuming sufficient energy is
available from energy storage pack
and the inverter is turned on.
If you are unable to connect to a
charge source in cold tempera-
tures, monitor the State of Charge
to ensure the electrical systems
and the heating pads do not fully
deplete the Volta System SOC.
Cold Temperature Operating Strategies
Monitor the SOC Gauge or touchscreen alerts when the Energy Storage
Pack is too cold to charge to ensure precautions are in place to prevent the
SOC from dropping too low.
