Circuit for dropping sense voltage to alternator regulator to increase output voltage.
Press momentary button to 'excite' alternator.
Simulating alternator sense with input to VCVS and output of alternator with output of VCVS. Adjust potentiometer to adjust voltage drop across MOSFET.
Zener diode to limit max voltage.
This is a proof of concept only.
The idea behind this is due to most alternators in modern vehicles being controlled by the ECU and providing a low charging voltage to the lead acid battery which ultimately will shorten its life.
By increasing the charging voltage slightly we may enable the battery to be fully charged.
Further ideas would be to include current sensing on the alternator output allowing voltage to be lowered to a 'float' level when current falls below a preset threshold, or after a predetermined time as well as temperature compensation for extreme hot/cold environments. Of course the would require some sort of MCU.
