A Volta System typically contains an energy storage source (Flex Pack), an alter-
nator for charging during driving operations, an inverter/charger for shore power
charging and 120 VAC power distribution, and converters to create DC power at
various voltages. To simplify the installation process, certain power distribution
components may be combined into a Power Distribution Hub. Combining
elements into a centralized hub makes the system integration easier. Your
actual system may vary in size, complexity, power distribution devices used, or
other application specific variations.
The Volta System and power distribution systems are similar in complexity
to a vehicle engine or generator. Therefore, only Volta technicians or trained
professionals with in-depth knowledge of Volta Systems should service these
components.
Flex Battery Management System
The safety control logic within a Flex Pack is contained in a system controller
known as the Flex Battery Management System (BMS). The BMS optimizes pack
performance and protects the pack against extreme operating situations. The
BMS continually monitors pack performance, and in the case of abuse, neglect,
or failures, it will shut off Volta power distribution devices and/or energy to the
Flex Pack.
Information regarding the system, or pack status, is available from the Flex Pack
via CAN communication. This information can be viewed on an OEM display by
reading the CAN data stream. Contact your Volta representative for information
about connecting a Volta system to a non-Volta display. In the absence of a
display to read CAN data, the SOC gauge and pushbutton flash codes can assist
in diagnosing system operation if the BMS detects any issues with the pack or
system operation. Refer to “Pushbutton LED Indicators” on page 18 and
State-of-Charge (SOC) Flash Codes on page 20.
Volta System Components
Your Volta System may be configured with the following options:
•Flex Pack: The Flex Pack is the energy source for your Volta System. A
14-gauge steel housing protects the lithium-ion cells, and an internal
Battery Management System monitors the system, balances the cells,
and controls energy output.
•Inverter/Charger: The inverter changes the Flex Pack’s energy from
direct current (DC) into alternating current (AC) to power the vehicle’s
120V AC devices (air conditioner, heater, cook top, etc.). The inverter also
converts shore power (AC) to direct current (DC) for charging the Flex
Pack.
•DC-DC Converter: The DC-DC converter drops the Flex Pack’s energy
from 58V DC to power your vehicle’s 12V DC or 24V DC devices (vehicle
electronics, lights, refrigerator, etc.).
•Secondary Alternator: The high-powered, secondary alternator provides
charging power directly from your vehicle’s engine to the Flex Pack.
•Solar Controller: The solar controller regulates solar power input from

VPS-DOS-TR-04-E / Rev 05
26-July-2023
Volta Power Systems Page 15 of 40
external solar panels into a stable, usable form of energy to charge the
Flex Pack.
•On/Off Pushbutton: Press the On/Off pushbutton to turn on or off the
Volta System.
•Touchscreen: Use the Touchscreen to monitor and control the Volta
System.

In Shore Power Mode, the Flex Pack charges as necessary and maintains
optimal temperature for charging and discharging. Also, if shore power is lost,
the Volta System shuts down automatically. This mode is ideal for short term
storage, when preparing for a trip in cold weather, or for any scenario where
it is important for the system to shut down in case of shore power loss (power
outage, accidental unplugging, or if a breaker or GFCI trips).
Also, when in Shore Power Mode, the AC loads in your vehicle (air conditioner,
cooktop, outlets, etc.) are powered from the charge source. Exceeding the rated
capacity to the charge source may result in tripped breakers or load shedding.
Depending on your upfitter or OEM configuration, DC loads may or may not be
operational while in Shore Power Mode.
