Description

1260486 V. The invention belongs to the technical field of the invention: The invention relates to a smart battery, in particular to a keyboard controller of a notebook computer capable of detecting various operating states of the smart battery and generating according to the action states Corresponding state values, such that the light-emitting elements provided on the keyboard or battery charger of the notebook computer generate different illumination modes, or the basic input/output system of the notebook computer displays the status value, so that the user From the illuminating element or the basic input/output system, the various states that occur are known. Previous technology: Press, notebook computer is developed for the convenience of consumers, and the biggest difference between notebook computer and desktop computer is that the former sometimes relies entirely on battery operation, therefore, the power management of the battery itself. Function, it becomes the most important function in notebook computer battery technology, because the length of battery life not only affects the length of time consumers use, but also the revolution in battery technology can achieve long life and light and short size. And further reduce the burden on consumers. However, today's microprocessor manufacturing and R&D companies are constantly introducing faster processing and more powerful microprocessors, and the power consumption of notebook computers is also increasing proportionally, thus forcing notebook manufacturers. It is necessary to develop a more efficient battery power and power management technology. However, the general notebook computer terminal users are expected to have the characteristics of short and light, and if they increase the size of the battery, they will increase the power supply. Contrary to user needs, so without increasing battery size

At present, there are two methods in the industry: (1) In terms of battery chemistry, starting from the battery itself, by developing different materials to achieve this purpose; (2) Starting with a battery management technology that promotes higher efficiency. The following is a description of the battery management technology that is most easy to handle for manufacturers of general notebook computers: Since today's state-of-the-art notebook computers are equipped with batteries that provide extremely accurate control of battery capacity saturation, It is achieved by a technology called π smart battery technology, which includes a charge accumulation sensor, a temperature sensing device, and other sensing devices to accurately detect changes in the end of the charging cycle. The battery is usually operated as an I2C, called System Management Bus (SMBus System Management Bus) as a two-wire interface. After the battery has more functions, it can communicate with the system and the charger. So the system or charger can know when the battery voltage and current can be charged, how much the battery can be charged, and when the battery will run out. And the accuracy rate can reach over 98%. In other words, after the smart battery is connected to the I2C/SMBus interface, it can report the poor material, store its own status, report the error, accept the parameter adjustment, and report its status. - When the AC is connected to the notebook, whether the notebook is on or off, the smart battery technology can charge the battery, the voltage volts and current, and the temperature are carefully monitored. The Battery Sensing F Meter 'returns various data to the smart battery charger, which contains LMD (main counter and capacity).

1260486 V. INSTRUCTIONS (3) reference / last measured discharge main counter, capacity reference table / last discharge capacity), DCR (discharge count register), and MAC (nominal available c h a r g e r e g i s t e r proposed charging count annotation). The discharge current is closely related to temperature. This advanced technology is designed to ensure that the battery can be used efficiently to avoid undercharging or overcharging the battery pack. Before the battery went on the market, it had to undergo a charge and discharge learning cycle in the factory to adapt to its size and adjust to provide the maximum power for the notebook. As for the above description of the smart battery technology, the current Zhisi Hui battery technology 'only focuses on the battery charging and discharging control and display battery storage 'k for the user to understand the current state of use of the battery, but the battery uses a section After the time, if it fails to continue normal power supply, usually only the notebook computer is sent to the repair center for maintenance, and the repair center ^ repair time 'usually takes 1 to 3 days, which is for the user, It's a very troublesome thing, but if you can monitor the battery capacity and another way to monitor the battery's other conditions, you can let the user know clearly what is wrong with the battery, then the user can easily Have a preliminary understanding of the battery condition, for example: there is a message indicating that the battery can not be recharged, and the battery can not report the data to the charger 1, which will enable the user to "repair the fault", for example: directly update the battery without having to wait for the repair center The time spent on overhauling.

1260486 V. INSTRUCTIONS (4) In view of the fact that the present inventors have made long-term efforts to study and experiment, the inventors have finally developed and devised a method of outputting the state of operation of the smart battery of the present invention. An object of the present invention is to provide a method for outputting a smart battery operation method. The 5 Hai method is provided with a battery status table in a notebook computer. The battery status table includes the smart battery can be detected. Go to the action state' and match the state values of the action states, and use a system management busbar to connect one of the notebook computers with a smart battery and a keyboard controller. The keyboard controller can manage the convergence via the system Row, accessing the various operating states of the lithium battery, and querying the corresponding state value in the battery state table according to the operating state, so that the basic input/output system of the notebook can be selected and displayed The state value, or the corresponding state value according to the action state, causes the light-emitting component of the notebook computer or the battery charger to generate different illumination modes, so that the wisdom can be easily understood. Each operating state of the battery. — To further understand and understand the purpose, shape, structure and function of the present invention, the detailed description of the embodiment and the diagram are as follows: 41 Implementation: Press, SMbus (System Management Bus, Chinese translation system, busbar, SMbus is a two-wire bus (especially semiconductor 1C) developed for component communication, most commonly used on notebook computers to detect components Status and replacement hardware configuration pins

1260486 V. INSTRUCTIONS (5) (p u 1 1 - h i g h or p u 1 1 - 1 〇 w), for example, turn off the clock setting on D I Μ Μ (), or detect the battery capacity status. S M b u s has a data transfer rate of only 100 Kbit/s, which allows a single host to communicate with the CPU (Central Processing Unit) and multiple masters (m a s t e r s ) to send and receive messages with the client (s 1 a v e s). SMbus was first proposed by Intel Corporation. Now it is managed and maintained by SBS (Smart Battery System), which is an I2C (I nter-Integrated Circuit) developed by Philips (Phi 1 ips). Bus, Chinese translation IC connection bus) is simplified from the bus, so it can also be called an I 2 C bus. SMbus is a busbar consisting of two signal packs. It is used to communicate between the slower devices and the power management device on the system. The system can obtain the manufacturer, model and some control information of these devices. , error message and status, these two signals are SMBCLK and SMBDATA, which is the same as Clock (SCL) and Data (SDA) on I2C. Please refer to Figure 1 for the different devices connected. On the bus bar (B us ), there is only one master (Master) on the SMbus. All commands are sent by this master. Other devices (S 1 ave ) can only receive commands or responses from the master. Information to the host. Please refer to Figure 2, when SMBCLK is high (High), and _ SMBDATA is changed from high to low (Low), it means to start a SMbus command, and when SMBCLK is high (High), and SMBDATA When the low potential is high, it means to end a SMbus command. These two conditions are unique in the Srabus. It is impossible to transmit data in general. When transmitting data in general, it is every SMBCLK. Rising edge
