Description of the Invention: [Technical Field] The present invention relates to a device for changing the charging or discharging performance of a battery according to the state of the rechargeable battery to improve the safety of the rechargeable battery and to extend the life of the battery. [Prior Art] In recent years, rechargeable batteries made of battery cells of various materials have been widely used in various fields of portable electronic modules because of their small size, light weight, and long time-consuming convenience. On the group. However, such a rechargeable battery that uses chemical energy to store electrical energy, whether in the process of charging or discharging, because it converts energy into a process of storing energy, both processes are accompanied by the release of thermal energy, which is inevitable The heat energy is bound to increase the temperature of the rechargeable battery. Therefore, in the use of smuggling, the designer must consider the moderate control of the rate of charge and discharge, and stop charging and discharging the battery in time to avoid the full conversion of the electrical energy into heat energy, resulting in a substantial increase in temperature. In this case, especially after the battery is repeatedly charged and discharged, the battery characteristics are deteriorated, that is, the so-called battery aging is more serious, and the aging battery temperature change is much more than normal. In order to solve the above safety problem, the user can maintain the temperature of the rechargeable battery within a safe range even in the case of excessive or improper use, and the rechargeable battery is often matched with a protection IC circuit for monitoring. The charging and discharging situation of the rechargeable battery 'When the charging voltage is higher than a certain voltage, the protection circuit will cut off the charging circuit, so that the battery can only be discharged at this time without charging, so as to avoid overcharging and over-discharging. Security issue. 200915698 However, the ic protection circuit sometimes has a poor quality due to a or some manufacturers' special intentions, omitting the various reasons such as the protection circuit, reducing the production cost and causing combustion or explosion. Come: =: It is also a laptop or mobile phone with a temperature that is too high, because it is safe = part of the brand type. Battery Wen Wang must be full of doubts

The aging mentioned in the above (4) Λ //14 is now a significant benefit to the safety of the battery or the life of the non-疋 battery, regardless of the temperature of the battery. Further, [Draft] This is to solve the above-mentioned problems in relation to changing the battery charging or discharging according to the state of the battery. The main concept of the invention is that the detected value reaches the state parameter of the Boz-cho Valley, and when the battery load is detected and reduced, the battery is loaded with two: The more dangerous state 'control mode and the first two:, and is in a safe state. In addition to this, it is possible to extend the life of the battery. The discharge is broken. In addition to the multi-layer protection, the f is used when the battery system is internally or externally equipped with a foot-scheduled condition. When the battery status is full, a warning message is issued. When the microprocessor 200915698 in the module reaches the warning signal, it will reduce the warning signal according to the warning signal, so that the load and discharge rate of the battery can be reduced. Temperature change...In order to ensure that the battery reaches the condition of charge and discharge, it will issue a warning signal to reduce its charge to further ensure its safety. Another advantage of this invention is that some products are configured to reduce the cost and configure the rated output power to be less than The battery system of the electronic module with rated power input, or the charging of a charger with a larger power, etc., and the device of the invention enables the system to effectively ensure its safety. Referring to the invention, the number of detection batteries is 'when the number reaches a certain value, it is determined that it is in aging electricity; this reduces the voltage value of charging and discharging the battery, The method reduces the overcharge or overdischarge of the battery, and the battery life is further extended. The invention can be improved compared with the above, and the present invention has safety and life with the prior art. [Embodiment] The above and other technical contents, features and effects will be apparent from the following detailed description of a preferred embodiment with reference to the drawings. Referring to FIG. 1, a preferred embodiment of the present invention, The portable module 101 of the embodiment refers to an electronic module having a rechargeable battery 124, such as a notebook computer, a mobile phone, a PDA, etc. In this embodiment, the 5x electronic module 101 is a matching one. For example, the smart battery system (SBs; Smart Battery System) 104. The aforementioned smart battery system means that the package 200915698 includes a system manager bus (SMbus) 34, a charging control unit 144, and a direct sensing unit 114. The system of the smart battery 124 can transmit the signal sent by the sensing unit to the control unit 1G3 that can communicate with the host through the system bus 134', and the control unit produces No. to the module host 102. The above control unit may be a CPU or a GPU built in the module host as shown in FIG. 1 to control the overall module host performance, when the sensing unit is tracked to any When the internal parameter of the battery is higher than a predetermined value, and the ^ σ signal is sent, the control chip generates a control signal, so that the overall electronic module can relatively reduce its operating frequency or voltage, thereby reducing the battery requirement of the module. The power provided by the system can reduce the load of the battery pack, thereby reducing the chance of the battery burning and burning. The warning signal of the sensing unit can be based on the current detected by the sensing unit in the smart battery system. The value is based on the flow chart of FIG. 2, when, as in the case of step 201 in FIG. 2, the current value of any battery is higher than "the value of the threshold is as follows: 1.2C ("C" is - one for indicating manufacturing The term “electricity, the amount of discharge grid”, which is measured in milliampere hours (mAh), is likely to cause the battery to burn because of excessive current, so the sensing unit sends the warning signal. Come Issued over control of the control unit number for inquiry made in step 202 of FIG. 2, the various operations of the host control module wafer down or step-down. Next, the current value of the battery is detected again through step 203. Repeating the step, the judgment of 201, checking whether the current value of the battery is lower than the threshold value, and if the current value is still higher than the predetermined value, repeating step 202, continuing to lower the operating frequency or voltage of each wafer, and Steps 203 and 2〇1 are repeated until the current value of the battery is thus lowered below the constant value. At this time, the feeling of 200915698 = yuan no longer issued a warning signal, so each lower, such as the step, each wafer will maintain the current level of operation frequency frequency or power, in addition to detecting current, the sensing unit can also detect The pool parameters are controlled as shown in Figure 3, and are; ^# temperature is too high to burn', so the steps such as 3d are also because the temperature of the pool is higher than the -th threshold value, such as two = not *, but because of the temperature High battery characteristics may cause a large amount of chemical substances inside the pool, or this electrical concern. +Initial negative chemical changes, there is a burning or explosion, = single two 'reduction of the operating frequency or voltage of the module host through the lightning signal of the warning signal of the sensing unit, and then wait for step 303 - the first time (4) to achieve a stable balance under the frequency or voltage of 2刼2, and then pass the second value of the second: as in step f5 3C04 to detect whether the temperature of the battery system is lower than the second valve. At 55oC, this second threshold setting ensures that the pressure does indeed cool down. When the battery temperature of step 30 is lower than the second threshold, it means that the module performs step 3〇5, and the CPU or GPU St pressure is further increased to maintain the working performance of the electronic module, and After a second time, 'return to the starting step to perform the step sound test; if the judgment result of step 3〇4 is no' battery system temperature: it is the second threshold value, it means that the temperature of the system is still Above the danger, the CPU or G p U operating frequency or voltage is used to protect the sub-module, and it is safe, so repeat steps 3〇2, 3〇3 and 3〇4 until the battery is brewed. Below the second threshold, proceed to step 3〇5. In addition to the current and temperature, the sensing unit can also calculate the number of times the battery is charged and discharged. In order to reduce the foregoing process, the battery will generate current when the battery is overloaded and discharged, and the battery characteristics are degraded. Or the temperature changes greatly and is difficult to control, so the steps are as shown in step 4〇1. When the number of times of charge and discharge is higher than a certain value, for example, 100 times, the charging control unit of the component 144 is used to perform step 402 to reduce the voltage of the battery charging. Current, which can improve the safety of the entire module and the life of the battery. The flow chart of the three detection and control modes of Figure 2, Figure 3 and Figure 4 can be implemented either simultaneously or in parallel to ensure module security and battery life. In another example, the control unit can also be a 1C chip that can independently control the cpu or gpu, and does not necessarily need to be integrated in the module. However, the above description is only a preferred embodiment of the invention, and is not intended to limit the scope of the invention, and the features and spirits described in the scope of the invention should be equally changed and modified. It is included in the scope of the patent application of the present invention.
