An electric vehicle charger is a power conversion device designed specifically to charge vehicle batteries, available in DC and AC charger types.
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity. Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger.
