CHARGING THE FLEX PACK AND INCREASING
SYSTEM RUNTIME
The Flex Pack accepts charge from the sources described in the following
sections� Monitor the Touchscreen for any alerts that may prevent charging�
The Flex Pack only charges when required� There may be several factors pre-
venting the Flex Pack from charging, even while connected to a charge source�
The most common reasons are the Flex Pack is too cold to charge, or the BMS is
inhibiting charge because of a high enough SOC�
System Runtime
Similar to fuel tank levels responding to driving style, the time it takes to drain
a Flex Pack from “Full” to “Empty” depends on usage� The two largest loads in a
vehicle that affect the runtime are typically heating and cooling� The more the
heating and cooling systems run to maintain the desired temperature inside the
vehicle, the more energy is used�
To maximize runtime:
• Turn off the inverter if 120 VAC loads are not required: When 120 VAC
devices (air conditioner, heater, cooktop, etc.) are not in use, turn off the
inverter via the touchscreen� Refer to Inverter Screen on page 19.
• Increase the thermostat in warm climates:
Increasing the desired
vehicle temperature reduces the amount of time the air conditioner
compressor needs to run in warm climates�
• Decrease the thermostat in cool climates: Decreasing the desired
vehicle temperature reduces the amount of time the heating system
needs to run in cold climates� Generally, heating using electricity uses
almost twice the energy as cooling�
Charging via Shore Power
Volta recommends a minimum 120V/30A rated shore power cord less than 50 ft.
in length� The OEM should follow NEC or RVIA guidelines for the specific appli-
cation requirements�
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� Addi-
tionally, the system may not accept a charge if plugged into an electronic surge
protector�
When connected to shore power, the Volta System first provides power to any
accessories drawing power from the Flex Pack� The remaining current is then
used to charge the Flex Pack at the rate chosen on the Inverter Screen on the
Touchscreen� Refer to Inverter Screen on page 19 for details on changing
the charge rate selection.
