Multistage Charging Process
The Enerdrive ePOWER Battery Charger is a fully automatic, “set and
forget” charger. It is designed to quickly and accurately recharge your
batteries using algorithms that help maximise service life. Multistage
smart charging technology enables the charger to be connected to
your battery banks permanently.
As dictated by battery manufacturer’s recommendations, batteries
require a multistage charge sequence for perfect, fast and accurate
charging. Our ePOWER multistage smart chargers deliver four primary
charge stages:-
Stage 1 - Bulk or Boost Charge; The battery is charged at full rated
output current of the charger until the battery reaches its final
charging voltage, known as its absorption voltage. In this step, around
80% of the battery capacity is recovered as fast as possible.
Stage 2 - Absorption Charge; With the charger voltage held steady
the remaining 20% is replaced allowing the current to drop as the
battery approaches its full charge.
Stage 3 - Float; Finally, in the float stage the charger voltage is lowered
and held at a constant and safe predetermined level. This prevents the
battery from being overcharged while supporting any additional loads
connected to the battery, such as DC lighting and refrigerators. This
stage allows for the charger to be used as a DC power supply.
Stage 4 - Maintenance; This stage is a regular timed “return to bulk”
stage. After 7 days of constant operation in “float” the Enerdrive
ePOWER Battery Charger will switch the charger from float to bulk
to agitate the batteries electrolyte helping to provide an extended
service life.
It’s All About Lithium
The recent advances in high capacity Lithium battery technology have
seen the need to develop a battery charger suited to their needs. With
most traditional ‘smart’ chargers their suitability to Lithium batteries is
limited. Lithium batteries require a constant current / constant voltage
charge algorithm and are unique in that almost every amp-hour of
charge delivered by the charger is accepted as one amp hour into the
battery, hence the need to deliver a constant current as long as possible.
The Enerdrive ePOWER charger can be programmed for Lithium
batteries. This setting delivers the full rated output of the charger
constantly with the charger switching to power supply mode once the
voltage peak is met (indicating a full battery bank). The graph below
shows the ePOWER charger algorithm perfectly supporting Lithium
battery requirements.

Bank 1 PRIORITY – Charge Where You Need it Most
The ePOWER Charger delivers a priority charge to Bank 1, or your
main house battery bank which allows the charger to get this bank
recharged the quickest, then transition the cycle to the lesser bank 2
& 3 batteries. The priority function also allows you to have a battery
chemistry different to the other two, such as an AGM battery for house
and lead calcium for your start banks. In the event that all 3 banks are
in need of a charge, an over-ride function helps recover all 3 banks
quickly and evenly before switching back to prioritise on Bank 1.
