An electric vehicle charger is a power conversion device specifically designed to charge vehicle batteries. These chargers are categorized as DC chargers and AC chargers based on their functionality and output characteristics.
Most battery manufacturers recommend sizing the charger at approximately 25% of the battery capacity. For example, a 100Ah 12V battery would require about a 25A 12V charger.
