USING THE VOLTA SYSTEM IN HOT AND COLD
TEMPERATURES
Refer to Flex Pack Programmed Operating Limits on page 26 for details on
the hot and cold temperature operating limits�
The touchscreen displays the Flex Pack temperature and the following indica-
tors to assist in hot or cold climate operation� Refer to Touchscreen Overview on
page 15 for additional touchscreen details.
Flex Pack Temperature Low: Flex Pack is too cold to charge�
Heating Pads On: Heating pads are on and actively warming
the Flex Pack�
Pack Temperature High: Flex Pack is at or near the high
temperature shutdown limit�
High Temperature Operation
The Flex Pack is designed with passive cooling� The BMS shuts down the Flex
Pack or prevents charging at elevated temperatures to allow the Flex Pack to
cool�
The Flex Pack charges normally and distributes power normally up to 134°F
(57°C). At or above 134°F (57°C), the Battery Management System (BMS) shuts
down the Flex Pack�
To protect the Flex Pack, avoid using or storing the Flex Pack at or above 134°F
(57°C). Storage of the Flex Pack at elevated temperatures is not recommended,
as it will reduce the lifetime and capacity of the Flex Pack�
Cold Temperature Operation
The Volta System is capable of powering electrical systems below freezing
temperatures� However, if the Flex Pack temperature is too low, the system does
not charge�
For system operation in cold environments, and to maintain the Flex Pack at
charge-accepting temperatures, the energy storage modules inside the Flex
Pack are equipped with internal heating pads (see photo on next page). The
internal heating system operates automatically, as needed, assuming sufficient
energy is available from the Flex Pack�
To maintain normal system operation in cold temperatures, leave the Volta
System on and connect to a charge source whenever possible� This ensures the
heating pads activate when needed and the Flex Pack state-of-charge does not
discharge to low levels� If you are unable to connect to a charge source in cold
temperatures, monitor the State-of-Charge to ensure the electrical systems, and
the heating pads, do not fully deplete the SOC�
