Energy State Taper Charge Method
The Energy State Taper Charge Process monitors the battery for the full charged resting
voltage of the cells. There are tremendous advantages to this charge method.
* Zero overcharging
* Exceptionally low gassing (Up to 90% less)
* Non-Destructive Micro-Equalization at each full charge
* The battery’s chemical processes actually control the charging.
* No RFI or EMI emissions to interfere with radio equipment.
*Works with GEL, AGM, and Flooded Cell lead acid batteries.
The need for temperature compensation is greatly reduced because the plate voltage is not constantly
held at the critical plate saturation point. Consider using temperature compensation if your system is in
Arctic or extreme Desert conditions. Tapering is controlled by the battery's level of charge rather than a
set timer and fixed voltage as in PWM and other constant voltage charge methods. The battery takes
exactly what it needs rather than being forced to take a specific voltage. With the Flexcharge method you
can charge your battery bank indefinitely without any possibility of overcharging. The batteries will last
longer, require less watering maintenance with flooded batteries, and hold a better charge.
As charging begins the controller allows full charging current to pass directly to the battery. When the
battery voltage rises slightly above the plate saturation point, the controller opens the charging circuit.
The chemical charging process continues until the battery voltage floats down to a voltage slightly above
13.2V. At this point the battery is ready to accept another charge pulse. This charge regulation method is
actually controlled by the battery's ability to accept energy. When the battery needs more energy, the
controller applies it. Later in the charging cycle the controller will cycle ON and OFF sending full charge
current pulses into the plates. A process which charges with very low gassing, and equalizes the plates at
the same time. As the battery reaches a higher level of charge the amount of time the controller spends in
charge is reduced, and the time in rest is increased. At full charge the controller will apply short duration
pulses to maintain the battery at an average voltage of about 13.75 volts. This keeps gassing to a
minimum while effectively trickle charging, and equalizing at the same time.
