Why EVO1 called?
Due to an evolution of the automatic charger circuit that was
previously here. We can compare the above circuit
That exceeds the previous circuit:
* It can load different types of batteries, only changing the value
of R3 and changing one Zener diode D1 of particular value for each
* In case of power failure (power cut ) and the battery is fully
discharged when the voltage reset circuit immediately begins to
charge the battery. The previous battery after having been reduced
to a certain voltage could not operate the relay and therefore not
* The LEDs were positioned in such a way as to show if the relay is
actually activated or not, certain conditions were previously fired
two partially. Now always be on one of them, when the voltage is
missing the two went out.
