Glossary of battery charger common terms

  • AC Failure: Supply voltage is interrupted or lower than a predefined value, for a predefined length of time.

  • Phase Failure: Three phase Supply voltage is interrupted or lower than a predefined value, for a predefined length of time on one or more of the phases.

  • DC Failure: Voltage and Current on the DC Bus are simultaneously below their respective lowest acceptable levels; the low Voltage level normally relates to a value that is significant to the Battery, the Bus, or some other Load, while the low Current level is normally a value that relates to the sum of the minimum current demands on the DC Bus.

  • Ground Fault: An unwanted current leak to Ground on one of the DC Bus polarities on a "Floating Ground" system.

  • Equalize Cycle Timer: A timer that periodically starts a battery charger's equalize mode.

  • Equalize Timer: A timer that defines the length of time that a battery charger will remain in the equalize mode.

  • I/U Automatic Equalize: A system on a battery charger that initiates the equalize mode when the voltage on the DC Bus drops below a selected level, and terminates equalize when the voltage on the DC Bus rises above a second selected level; when the sum of the Load and Battery demands is high, the Charger Output current is limited to a set maximum until the current demand decreases below that set maximum.

  • Manual Overide of Charge Mode: A means allowing the manual selection of the "AUTO", "EQUALIZE" or "FLOAT" modes when an automatic mode selection system is present on a battery charger.

  • Filter, Output Ripple: A circuit that reduces or smooths the AC component remaining in the Output of an AC to DC battery charger to a level acceptable to sensitive Loads.

  • Tropicalization: Measures taken in the Design, Manufacturing, and Finishing of equipment to protect it from being damaged in a tropical environment.

  • Surge Voltage Suppressors: Devices that clamp Transient Voltage Surges induced by lightning or line disturbances of various kinds, to an acceptable level. There can be several stages, starting with a good grounding circuit.
    In a battery charger Surge Voltage Suppressors are normally positionned across the Rectifier input and output and are meant to act quickly allowing slower reacting more robust devices time to begin their work.
