lead acid efficient current
hello,
I am designing a battery charger for lead acid car battery (12v).
I want it to be very efficient, so i don't want to run the charging current through a resistor.
Does any reader think it will be allright to "drizzle" the current into the battery through an inductor instead?
-I mean, just have a 14 Volt rail......with then a mosfet connected (in the high side)
and then an inductor in series with the battery.....also i would have a high side current sense resistor and a high side current sense amplifier to sense the current and simply switch the mosfet off when the current got above the maximum charging current...then switch the mosfet back on again after a certian time....i.e. the mosfet switching on/off.
do you think this would be ok?
Best regards, and thanks in advance for any thoughts at all.
