Smart battery charger

A smart battery charger is mainly a switch mode power supply (also known as high frequency charger) that has the ability to communicate with a smart battery pack's battery management system (BMS) in order to control and monitor the charging process. Most comonly used type of comunication is the CAN bus communication between charger and BMS. The charge process is controlled by the BMS and NOT by the charger this increases security in the system. Not all the chargers has this type of communication and is commonly used for lithium batteries.
