Abstract:
The technology for solar battery charge controllers has undergone great advancements
in the past few seasons. The most emerging new technology isPWM algorithmic
charging technique, which gained popularity increasingly.Charging of battery with solar
panels is an exceptional and arduous challenge now a day. In the old days, simple on‐off
switches were used manually to limiter the battery from overvoltageand overheating,
when the solar panel produced excess energy in that time. However, as this energy
system advanced it became clearedthat how these simple switching devices interfered
in the charging process. The history of on offswitches has been early battery failures
before the full charging, increasing inauto load disconnection, and growing use
dissatisfaction. Pulse Width Modulation has recently prolonged technologyand it
significantly advance in sun power battery charging system.
This type of solar chargers usesthe PWMtechnique which has similarity with all other
battery chargers. When a battery voltage will reachesits highest level then the
regulation process will start. The PWM technique slowly reduces the voltage coming
from the panel to avoid the heating and overcharging of the battery. The charging
process continues to attain maximum amount of energy to the battery in the short
interval of time. The result conducted is the full charging with effectiveness, rapidness
recharging, and a full limit Dry cell life.
