Block Diagram Battery Charger. The presented battery charger is composed by two power converters that share a dc link. Ev charger block diagram.
220v25v transformer is used to bring voltage down. A ferroresonant charger is a class of chargers that employ a ferroresonant transformer to regulate the charger output. Here battery charger assp flash mcu ht45f5q x is the heart of ev charger circuitry with in built operational amplifiers opas and digital to analogue converters dacs that are necessary for battery charging function.
There is also a trickle charge mode circuitry which will help to reduce the current when the battery is fully charged.
Battery charger circuit diagram. Lead acid battery chargers typically have two tasks to accomplish. Excess electricity and energy stored in the battery during the day will help feed the house during peak consumption and energy cost periods. The step down voltage is changed to pulsating dc with the help of a full wave rectifier d 1 and d 2 and is smoothed by capacitor c 1.
