IOT Based Car Lighting System Using VAWT

Abstract

The lead acid battery is widely used by current automotive vehicles and other applications
whereby charging is required. It is known that the alternator in the car will start charging the battery when
the car is started. The alternator charges the battery whenever the car runs in normal situation. However,
extreme temperatures and wear can affect the normal cycle of charging and discharging of the battery as
well, thus reducing the reserved capacity of the battery. Therefore, during the season of extreme temperature
such as summer and winter, the alternator may not able to supply enough electricity to run all the accessories
when the electrical uses load, such as lights, radio and fan exceeds the amount of electricity charge. It is
possible to creates a load that the alternator cannot handle, and the battery would end up discharging. The
lead acid battery is not designed for deep discharging and it can reduce its lifespan. With the implementation
of wind turbine system on the vehicle, the lifespan of the primary car battery will be increased and there will
be a backup power supply that can be used in time of emergency such as the battery failure. The reason is
that the power storage which connected to the turbine will act as a secondary battery which is being charged
whenever the car moves during daytime. During the nighttime, the wind turbine will used to power up the
lighting system of the vehicle directly. This action will prolong the lifespan of the primary battery because it
reduces the usage of electricity of the primary battery. In other words, it reduces the cycle of charging and
discharging of the battery.
