The Wanderer utilizes Pulse Width Modulation (PWM)
technology for battery charging. Battery charging is a current
based process so controlling the current will control the battery
voltage. For the most accurate return of capacity, and for the
prevention of excessive gassing pressure, the battery is
required to be controlled by specified voltage regulation set
points for Absorption, Float, and Equalization charging stages.
The charge controller uses automatic duty cycle conversion,
creating pulses of current to charge the battery.
The Wanderer has a 4-stage battery charging algorithm for a
rapid, efficient, and safe battery charging. They include: Bulk
Charge, Boost Charge, Float Charge, and Equalization.

The duty cycle is proportional to the difference between the
sensed battery voltage and the specified voltage regulation set
point. Once the battery reached the specified voltage range,
pulse current charging mode allows the battery to react and
allows for an acceptable rate of charge for the battery level.
