[OpenTRV-dev] OT: Charge battery

[Bo Herrmannsen]

Hi

i have a few LCD’s and some other bits arround i want to put together to make an charger / discharger controlled by and arduino


dis charging is easy enough.... and the math to do it also


but how about charging... i would like to both be able to regulate voltage and current... depending on what type of battery i have connected...


i plan to have the supply voltage at 18-20V to cover most needs... if not i rip that old 18amp car battery charger and use the trafo in that one...


anyways what is the simple way to control voltage ? and how would i do current ?


/Bo
