Charging Modes - BMPRO J35 + ControlNode Owner's Manual

CHARGE MODE
Soft Start
Boost (J35B-L and
J35D only)
Bulk
Absorption
Float
The J35's intelligently-controlled charging algorithm automatically sets
charging parameters so that the caravan battery will maintain the best state of
health.

CHARGING MODES

Soft Start Mode
Charging current is maintained at 10A until the battery voltage reaches 12V or
soft start timeout occurs.
Boost Mode (J35B-L and J35D)
During Boost Mode, current is boosted to 30A to bring the battery voltage up to
14V, after which charging proceeds to Bulk Mode.
Bulk Mode
Charging current is maintained at 15A until the battery reaches the Bulk voltage,
after which charging proceeds to Absorption Mode
Absorption Mode
Battery is charged at Absorption voltage until the current drops below 2A or
Boost-Bulk-Absorption timeout occurs.
Float
Charging current is limited to 10A to keep the battery level topped up. Charging
will remain in Float for 6 hours. After Float timeout, the J35 will enter back into
Boost-Bulk-Absorption modes.
