ePower 12V 20A Smart Charger - EN31220
EN31220
Description
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. The 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.

Additional Information
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).
