Description

471194 V. Description of the invention (1) ^ The month is related to the protection circuits of various types of intelligent lithium-ion battery packs and their ionic power: ί The earth hardware circuit works in conjunction with software programs to address the performance of clock r 'and :: ^ Need to provide a design that can improve the overall impreciseness of the lithium-ion battery pack. Complement circuits and improve traditional protection circuit boards. The development of modern electrical products is moving towards thin, light, and short;;: Bao Yi products are introduced · 'such as mobile phones, notebook computers, video cameras, etc. Radio cassette recorders, etc., are constantly changing and being updated; basic and convenient tests, the new generation of battery materials with high energy density have been described and applied in succession; for example, rechargeable lithium-ion batteries (Li — i〇n = ttery) Because of its large capacity and light weight, it has been widely used in applications that support mobile communications equipment, notebook computers and other products, with added value and ease of use. Due to the limitation of the material characteristics, the charging voltage of “I… produced” bell-ion batteries should not exceed 4.2 v / cel 1, otherwise the service life of the lithium-ion battery will be greatly reduced. There is a danger of burning or exploding. This is because lithium itself has excellent affinity with oxygen; therefore, it is not possible to use a water-soluble electrolyte with oxygen-containing components for electrolysis of ion exchange = people such as potassium nitrate, etc. Therefore, it is necessary to use hydrocarbons with different oxygen content: two substances as electrolytes, such as kerosene leachate, etc. As for the discharge voltage limit through ion battery, the absolute voltage is generally prohibited to be lower than 2 · 7 v / cei 1, no = Will, the irreversible failure of the lithium-ion battery is over-discharged, so that its capacity cannot be restored and cannot be charged. Therefore, in addition to its safety, the reliability of the battery needs to be considered. Description of the Invention (2) ::: it: ί is installed in a bell-ion battery pack-a traditional protection circuit board to ensure absolute safety in use. The lack of r is a child: the advantages of the pool and avoiding its danger Use ^ All of the system components ^ value ions n are all equipped with a piece of completely profitable "heart protection system circuit board to overcome, but because-it must not be shared between electricity, no: the process management of the circuit board into a specification is extremely great Trouble ... Limited use of inventory control and production line due to the material characteristics of the ion battery. Due to the repeated charging == 1, the discharge of dust is prohibited to be lower than 2.7v / ceu, otherwise it will ... Need to consider the safety and time is usually installed in the clock ion battery pack-traditional protection ^ Road 2 to meet the queen. However, the protection circuit board has a high unit cost and a variety of complicated specifications, which causes many problems. For the traditional protection circuit board, please refer to the figure shown in Figure 1. Is the thermistor, thermal fuse, and charge control switch? The amplifier is made up of a safety switch, a button protector, a controller, and a plurality of lithium-ion battery packs. The thermistor detects the abnormal temperature generated by the lithium-ion battery pack during charging / discharging, and the thermal fuse is disconnected when it overheats to avoid high wind loss. This control IC controls switching between the charge control switch and the discharge control switch to charge or discharge the lithium ion battery pack. The short circuit protector provides circuit protection in the event of a short circuit. When the sub-battery pack is being charged, 'Because of the series connected battery cells in the charging circuit: due to the uneven influence of its internal resistance value, it will inevitably cause the inconsistent voltage division of the early limbs of each battery. Page 5 471194 with different internal resistance values V. Description of the invention (3) As a result of the terminal voltage of the negative electrode being inconsistently high and low during charging and discharging, the battery cell battery that reaches the upper limit voltage value stops charging at this time; It will not be able to charge and saturate; the long-term accumulation of interference effects during discharge will reduce lithium. Therefore, when the traditional protection circuit is powered, it will inevitably be targeted; this improper restraint is the main reason for the reduction. The reason is that 'the main purpose of the present invention is the battery pack protection circuit and method, the lack of intelligent capacity compensation of sexual performance is not accurate enough; especially when it is avoided, the long-term cumulative dry According to the foregoing, the needle of the present invention, during the charging process, applies this material 'control / load circuit' to unbalance the terminal voltage between the charging cells and super-parallel_electrical drop to load it to its terminal voltage. (That is, the capacity). At this time, the intelligent capacity of the present invention compensates for the load of the parallel power supply and continues to pin. The terminal protection circuit board will be generated due to the different internal resistance values. The condition of the battery cells whose lithium ions do not reach the upper limit voltage value is just the opposite. In this way, the rapid speed of the ion battery pack with abnormal capacity has incorrectly charged the final voltage of the clock ion battery pack into a clock ion battery. The abnormal capacity of the battery is to provide a smart lithium-ion battery that can improve the overall circuit of the lithium-ion battery pack and improve the traditional protection of the circuit board from the clock-ion battery. Group in the body of the charging or discharging efficiency and performance horses uneven interference effect. For the battery cells detected and recorded by the missing blade of the traditional protection circuit board, the terminal voltage value of the highest terminal voltage or the design upper limit value of the battery is exceeded. When the voltage is close to the same as other battery cells, the compensation circuit will immediately notify the load circuit to resolve the individual load processing. 471194

Until the function of the compensation circuit in the lithium-ion battery is the same as that of the lithium-ion battery (that is, the capacity of the fifth phase, the bell-ion battery pack of the invention description (4) continues to charge, so that all the battery cells in the battery pack are truly charged and saturated; For each battery cell in the group, the terminal voltage value of each battery cell will be the same due to the modification of the intelligent capacity of the present invention) and charged to the maximum saturation. Dozens of types of functional circuit boards can be used to open traditional circuit boards and reduce the cost of efficiency. In addition, the current bus and the special time data clock ion _ special program-controlled hardware traditional protection circuit all lack of production and invention. It is sure to avoid unevenness and to extend the intended use of specific remote processing and phase battery packs built into one of the invention's computers. The firmware of the invention only protects all the circuit boards, and the purpose of large inventory control is to control the electrical performance of the clock ion, and the purpose of extending the communication with the lithium ion power. The complexity of the function requires a large increased cost. It is the service of the battery pack that is caused by the poor charge of the battery pack. It is the service of the central server and the external pool management service, the remote adjustment of the hardware circuit parts, and the improvement of the polysilicon. Improved the accuracy of the traditional protection protection function, the function design of the quantity compensation, the function of the long-term cumulative interference effect life due to the formation of the battery cell when discharging. The microprocessor can communicate with the Internet through the data exchange, and then connect the service system for immediate operation, which can also be used as a technical model for the whole network service.
