Abstract:
In this study using the piezoelectric direct effect
(DEP) method. The existence of this method can be used to
generate voltages and currents from the piezoelectric. From
these data, it can be divided between series and parallel circuits
to carry out the battery charging process using a diesel engine
vibration. The results of this experiment, namely by using a
series arrangement will get a good voltage up to a value of 10.5
volts with a voltage drop of about 3 volts so that the resulting
current is about 30 mA. When using a parallel circuit the
resulting voltage is less than 0.8 volts so that the battery is not
filled. The estimated time taken for the research process is 50
minutes with an average power output of around 90.91 mW so
that the value of the mAh is about 19.38 mAh.
