    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).

  • Page 24: State Of Charge (Soc) Gauge

    STATE OF CHARGE (SOC) GAUGE SOC Overview Your Volta System may be equipped with an SOC gauge. The SOC gauge provides an approximate reading of how much energy remains in the pack. The flash codes and colors communicate basic system and fault states.
  • Page 25: Charging The System And Increasing System Runtime

    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.
  • Page 26: Charging Via The Secondary Alternator

    If incoming power meets the requirements, the Volta System turns on and begins charging the Flex Pack. If the Flex Pack does not charge from a generator, this condition may be due to unclean or unstable power from the generator.
  • Page 27: Recovery From Zero State-Of-Charge

    The Volta System can be integrated with a generator using an auto-start and auto-shutoff feature, creating a hybridized charging system that increases efficiency for the Volta System and the generator. Recovery from Zero State-of-Charge The Battery Management System shuts down the Volta System if the Flex Pack reaches a very low voltage limit or 0% State-of-Charge (SOC).

At or above 116°F (47°C), the Flex Pack will not charge. At or above 134°F (57°C), the Battery Management System (BMS) shuts down the...
  • Page 32 Heating Pad Cold Temperature Operating Strategies When the Flex Pack is too cold to charge, monitor the Volta System SOC and touchscreen alerts to ensure precautions are in place to prevent the SOC from dropping to 0%. When cold, the pack’s internal heating pads continue to draw power to warm the pack, which will cause the pack to lose power faster.
  • Page 33 If a charge source is not available, and the SOC is too low to activate the heating pads long enough to warm the Flex Pack, turn off the Volta System to limit power consumption. If possible, park the vehicle in a warmer location to raise the Flex Pack temperature, or contact Volta Power Systems for additional strategies to warm the Flex Pack to accept charge.
