Reasons the System will not Charge

There may be several reasons why the Volta System
isn't charging, even while connected via shoreline:
• The State-of-Charge is too high� If you are
attempting to charge the SOC to 100% from a SOC
greater than approximately 90-95%, the system will
need to deplete to below approximately 90-95%
before the system begins to charge again�
• The Flex Pack is too cold or too hot to charge;
Power System Temperature Limits on page 5-17�
• The shore power connection does not meet the
charging requirements controlled by the Flex Pack
BMS� When plugged into shore power, the Flex
Pack samples incoming power for a few seconds
to ensure uniformity requirements are met� If
incoming power meets the requirements, the Volta
System turns on and begins charging the Flex
Pack� If the Volta System does not turn on, or the
Flex Pack does not begin to charge, the incoming
power is likely not meeting the Volta System
requirements� This feature protects the vehicle
from brown outs due to insufficient power.
• The selected charge rate is not appropriate for the
shore power connection� You may need to raise
or lower the Charge Rate Selection;

• If you're using a plug-in surge protector, but you're
experiencing problems with your Volta System not
connecting to the attached shore power, attempt
the following test: Remove the surge protector and
plug the shore cord directly into your vehicle� If
your system is now able to receive shore power, it
may be that your surge protector is not compatible
with the Volta System�

Power System Temperature Limits

The Volta System is programmed with several
operational temperature limits to protect the pack and
prolong its life� For temperature limitations

The Volta touchscreen displays temperature indicators,
heating pad usage, alerts, and the Flex Pack
temperature� To learn about System Indicators,

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 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 Flex
see
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�
Do not expose the Flex System battery pack to
high-temperature locations greater than 140°F
(60°C). This includes intensive sunlight. Doing
so may cause the Flex Pack to overheat and may
result in a loss of performance and/or a shortened

Cold Temperature Operation

The Volta System is capable of powering electrical
systems below freezing temperatures� However, if the
see Inverter/
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�
The internal heating system operates automatically
when the Volta System is turned on (by the Battery
Power Pushbutton) or connected to shoreline power
in Charge Only Mode and when sufficient energy is
available from the Flex Pack�
