Smart battery

BMS interface examples are: SMBus, PMBus, EIA-232, EIA-485,[3] and Local Interconnect Network.

A smart battery can demand that the charging stop, request charging, or demand that the smart energy user stop using power from this battery.

The charge process is controlled by the BMS and not by the charger, thus increasing security in the system.

Linear Technology manufactures, such as the LTC4100,[5] or the LTC4101,[6] are Smart Battery System-compatible products.

Microchip Technology provides an application note for a smart battery charger based on the PIC16C73.

Almost all laptops use smart batteries.
