Looking to build my own custom battery charger/ trickle charger for my motorcycles.
Brief: I have 4 motorcycles That are ridden anywhere from daily/weekly to maybe only once a month or less. With time the security systems and always on accessories slowly drain the batteries.
I could buy a trickle charger for each bike but that would be quite costly alternatively I could put together a few readily available components to build my own smart charger. Idea being each bike has a little pig tails hidden somewhere easily accessible and when I park the bikes up I just plug them in walk away and for get about them until I ride them next.
This is what I am thinking:
240v ac - 12v dc PSU q. how many amps?
An Arduino to control the charging
A few 7 segment displays or maybe a single LCD display to indicate status (have both in my parts box)
Some voltage reading modules (have some in my parts box)
Relays (plenty in parts box)
Wire, terminals etc
I haven’t done much research but I am guessing it’s as simple as taking a reading from each battery, and cycling power from the PSU to each battery. Rinse and repeat and as hard as a bunch of technical data about charging/maintaining batteries.
Obviously I need to isolate the Arduino using the relays and voltage reading modules.
My skill level is intermediate, I can handle the code and the wiring, looking for help with the technical side of trickle charging and maintaining motorcycle batterie.
