Embodiment Construction

[0074] figure 1 A schematic diagram of the logical structure of the SmartBattery battery state control system constructed for the first step of the present invention. like figure 1 As shown in the hardware logic structure, the SmartBattery battery status control system consists of four parts: SmartBattery, Phytium 1000A processor, battery status control software and power management application. SmartBattery's lithium polymer rechargeable battery, power adapter, microcontroller unit MCU and battery management chip LTC4100 are the four core components of the Phytium 1000A processor, which are connected to the FT1000A processor's built-in AMBA ( The fourth I2C interface of the I2C controller under the AdvancedMicrocontrollerBusArchitecture) bus (that is, I2C interface 3). The address of the I2C slave device is 7 bits, and the 8-bit address needs to be completed by shifting and complementing operations when using it. In this embodiment, the addresses used by the two I2C slave ...

Abstract

The invention discloses a method for controlling a battery status based on a domestic Fei Teng processor. The method is used for obtaining in real time various information of an intelligent battery and controlling a charge and discharging status of the battery. The technical scheme is that a battery status control system of Smart Battery formed by the Smart Battery, a Fei Teng 1000A processor, battery status control software and a power supply management application is built first, battery status information is obtained by the battery status control software according to the cycle T by accessing a register related to LTC 4100, the battery status information is wrote in a proc file system, the power supply management application is provided with upper limit threshold value of the charge quantity of electricity and lower limit threshold value of discharge quantity of electricity, structured battery status information is obtained by the power supply management application from the Proc file system according to the cycle T, and the charge and discharge of the battery of the Smart Battery is controlled. According to the method, the control of the battery status of the Smart Battery based on a Fei Teng processor platform can be implemented at low cost, and the compatibility, the adaptability, the flexibility and the extendibility are good.

Description

technical field [0001] The invention relates to the field of power supply management, in particular to a method for controlling the battery state of a reinforced portable computer based on a domestic Phytium processor. Background technique [0002] The battery state control method mainly realizes two functions of battery real-time information acquisition and battery charging and discharging state setting. Acquisition of battery real-time information means that the operating system kernel obtains the real-time state parameters of the battery from each register of the battery and writes them into the user space; battery charge and discharge state setting means that the application program in the user space sets the charge and discharge state of the battery according to the real-time information of the battery . The method is generally used to obtain and control battery information of a portable computer, thereby supporting the realization of related functions of power managem...
