Blue Smart IP22 Charger

To access the expert mode settings:

1. Open the 'advanced setting' page and enable 'user defined' configuration - see the 'Advanced configuration > Advanced settings' section for instructions.

2. Toggle the 'Expert mode' switch on to enable additional 'Expert mode' settings (extension of the 'advanced settings' menu).

   

3. Read the warning message and then select 'OK' to accept and progress.

   

4. The ‘Expert mode' settings (extension of the 'advanced settings' menu) will now be enabled.

   

The ADDITIONAL expert mode settings include:

1. Charge voltage

   1. BatterySafe

      The BatterySafe setting allows the BatterySafe voltage control to be enabled or disabled. When BatterySafe is enabled, the rate of battery voltage increase during bulk stage is automatically restricted to a safe level. In cases where the battery voltage would otherwise increase at a faster rate, the charge current is reduced to prevent excessive gassing.

2. Bulk

   1. Bulk time limit

      The bulk time limit setting restricts the maximum time the charger can spend in bulk stage as a protection measure, since the absorption voltage should have been achieved by this time. If the bulk time limit is satisfied the charger will move directly to float stage.

   2. Re-bulk method

      The re-bulk method setting allows selection between constant current or battery voltage method to trigger the charger back into bulk charge stage. When the charger is configured in a VE.Smart network with multiple chargers this setting is overridden and battery volatage is used.

   3. Re-bulk voltage offset

      The re-bulk voltage offset setting is used to determine the re-bulk voltage threshold that will trigger a new charge cycle; the offset is relative to the configured 'Storage voltage' (re-bulk voltage = storage voltage - re-bulk voltage offset). If the battery voltage falls below re-bulk voltage threshold while the charger is in float or storage stage and remains below it for one minute, the charger will move back into bulk charge stage.

   4. Re-bulk current

      The re-bulk current setting is the charge current limit that will trigger a new charge cycle. If the charge current exceeds the re-bulk current threshold for four seconds while the charger is in float or storage stage, the charger to move back into bulk charge stage.

      Note that even when the re-bulk setting is disabled, re-bulk will still occur if the charge current is maintained at the maximum charge current for four seconds while the charger is in float or storage stage.

3. Absorption

   1. Absorption duration

      The absorption duration setting allows selection between adaptive absorption time (calculated based on the bulk time / level of discharge) or a fixed absorption time.

   2. Maximum absorption time / Absorption time

      The maximum absorption time / absorption time setting enables the maximum adaptive absorption time or the fixed absorption time to be configured (depending if adaptive or fixed absorption time is selected). Note that regardless if adaptive or fixed absorption time is selected, the absorption phase can end early based on the tail current setting (if enabled).

   3. Tail current

      The tail current setting enables the absorption stage to be ended early based on charge current. If the charge current drops below the tail current threshold for one minute, the absorption stage will immediately end and the charger will move to float or storage stage.

   4. Repeated absorption

      The repeated absorption setting enables the elapsed time between each automatic refresh charge cycle (1h in absorption stage) to be configured. Repeated absorption is enabled by default and can be disabled which results in the battery staying in storage mode indefinitely.

4. Recondition

   1. Recondition current percentage

      The recondition current percentage is used to establish the charge current limit while the charger is in recondition stage; the percentage is relative to the configured 'Maximum charge current'. The charger will limit charge current to this lower level while in recondition stage.

   2. Recondition stop mode

      The recondition stop mode setting allows selection between the recondition stage being ended upon the battery voltage reaching the recondition stage voltage setpoint or a fixed time period.

   3. Maximum recondition duration

      The recondition time setting enables the maximum recondition time or the fixed recondition time to be configured (depending on the recondition stop mode selected).
