VOLTstack Power States
Discharging (negative Net Power):
Power State in which the net power is less than zero, and the VOLTstack State of Charge is decreasing
Charging (positive Net Power):
Power State in which the net power is greater than zero, and the VOLTstack State of Charge is increasing
Idle (zero Net Power):
Power State in which the net power is zero and the State of Charge is decreasing according to the
self consumption of the VOLTstack Power Mode.
Amp Hour (Ah)
Amp hour is a unit of measurement for electrical capacity commonly used for battery storage devices. One
amp hour is equivalent to one amp being used continuously over a 1 hour period.
Battery Management System (BMS)
Battery Management System is an integrated controller that monitors and protects a Battery Pack from
harmful conditions such as short circuits, over charging, over discharging and temperature eects.
Battery Pack
A Battery Pack consists of a fixed number of battery cells combined in series and/or parallel to form a higher
voltage and capacity battery. The cells are assembled into a protective enclosure with an integrated Battery
Management System.
Face Plate
The Face Plate is located at the front of the VOLTstack. It serves as the user interface and contains all
charging and output controls. See the Component Identification and Location section for details.
KiloWatt Hour (kWh)
Kilowatt hour is a unit of measurement for electrical energy, it is analogous to “litres of gasoline”. One
kilowatt hour is the amount of energy equivalent to 1000 watts being used continuously over a 1 hour period.
