7.4. Four-stage charge algorithm

MP_500VA_-_Charge_graph.PNG

charge stage

Description

Bulk

Entered when charger is started. Constant current is applied until the gassing voltage is reached (14,4 V resp. 28.8V, temperature compensated).

Battery safe

If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Multi will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached. The Battery Safe period is part of the calculated absorption time.

Absorption

A constant voltage period to fully charge the battery. The absorption time is equal to 20x bulk time or the set maximum absorption time, whichever comes first.

Float

Float voltage is applied to keep the battery fully charged and to protect it against self-discharge.

Storage

After one day of Float charge the charger switches to storage. This is 13,2 V resp. 26,4 V (for 12 V and 24 V charger). This will limit water loss to a minimum. After an adjustable time (default = 7 days) the charger will enter Repeated Absorption for an adjustable time (default = 1 hour).

7.5. Temperature compensation charge chart

MP_500VA_-_Temperature_graph.PNG
  • Default output voltages for Float and Absorption are at 25 °C.

  • Reduced Float voltage follows Float voltage and Raised Absorption voltage follows Absorption voltage.

  • In adjust mode temperature compensation does not apply.
