ABSTRACT:
A smart battery charger system including a smart battery charger that responds to charging instructions of a smart battery. The smart battery includes a memory that stores battery-specific charging characteristics. The smart battery determines a desired charging voltage and desired charging current based on measured environmental conditions, such as battery temperature, and the charging characteristics. A bus allows the smart battery to communicate the desired charging voltage and charging current to the smart battery charger. The smart battery charger generates the actual charging voltage and charging current in response to the desired charging voltage and charging current. In this manner the smart battery can control its own charging. Charging can be optimized according to a particular smart battery's charging characteristics and requirements.
