Microcontroller (MCU) is a well used power management devices, the use of micro-controller can realize the power system more complex and effective control and monitoring, the first use of the power control commands is the power on / off control command, and then, with the power system in the use of micro-control devices, can easily achieve power output voltage / output current control parameters and other related work. For example, the use of a "digi pot" of the simple parts can be adjusted by the microcontroller power supply voltage detection signal and the parameters of the current detection signal, and "digi pot" kind of device is a lot of advantages of using I2C bus devices one. I2C bus can be achieved by memory, displays, sensors and interconnection between the power controls IC.
As early as 1995, through a variety of bus (eg RS-232, Single (One Wire), SPI and I2C , etc.) completed a battery management, time management, physical interface for communication, command, data formats, there is no uniform industry standard. Duracell Inc. and Intel Corporation have developed a smart battery system SBS (Smart Battery System), its purpose and the battery type you want to make a senior independent and accurate battery management system, and make the smart battery management system can be applied to different production of rechargeable battery manufacturers, rechargeable battery charge management, and reduce the intelligent battery management system to support the burden of a variety of communication control protocol, the physical communication protocol is the System Management Bus (SM Bus), and the command language is the smart battery data SBD ( Smart Battery Data).
System Management Bus (SM Bus) is a version of I2C bus is a smart battery system (SBS) of the physical layer. Smart Battery System (SBS), a layer of an order, and smart battery system components in the order between the response, smart battery, 200w power supply, smart charger and smart use of SM Bus Selector general command to complete the relevant control information transmission and response. Many of these commands and the commands in the same I2C , use these commands to complete the battery capacity and monitoring of working conditions. But also more importantly, the Smart Battery System (SBS) in the main control circuit the battery or charger can also send control commands to the intelligent use of these control commands to set the charger's output voltage, output current, and other important operating parameters. In most cases, the resolution of the output voltage in the mV order of magnitude, the resolution of the output current in mA order of magnitude, the use of SMPS Bus can be completed regardless of the type rechargeable battery and charger system management and control.
