Description of the invention 彳) Bright background '(Please read the precautions on the back before filling out this page) This invention relates to the improvement of the safety of the battery in the battery device and the accuracy of the remaining energy calculation It is improved, and a battery condition monitoring circuit capable of calculating the remaining energy of a storage battery such as a lithium ion battery. Common battery status monitoring circuits are known, as shown in the circuit block diagram of FIG. For example, Japanese Patent Application Publication No. 9-1 3 1 2 1 7 2 " battery pack, charger, charging system, and charging method " published the structure shown in Figure 2, which is related to the so-called smart battery System-level battery device. Lithium-ion batteries used in smart battery systems require overcurrent protection circuits because of their self-protection, such as those in nickel-cadmium batteries. To this end, the battery device is equipped with a battery voltage monitoring circuit 4 · Α to detect the battery voltage, and the switching element 1 2 A to stop the charging operation from the outside. Printed on the battery device 2 2 A by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, when it receives the signals A 3 A and A 4 A from the current monitoring circuit 3 A and the current and voltage monitoring circuit 4 A, it is used as an information processing device. Six of the microcomputers monitor the battery voltage, charge current, and discharge current of seven people, eight six, nine eight, and 10A. Using this information (respective battery voltage, charge current, and discharge current), the microcomputer 6A calculates the remaining energy of the batteries 7A, 8A, 9A, and 10A, and controls the switching elements 1 2 A used as current limiting devices, and 1 3 A opening / closing operation to control the charging and discharging operations of the battery 7 A, 8 A, 9 A, and 10 A. Inventive Note: This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. A7 B7. 5. Description of the invention i) Battery device 2 2A is structured for execution Battery 7A, 8A, 9A, and 10A remaining energy display, and stop charging operation. Microcomputer 6 A self-current monitoring circuit 3 A and battery voltage monitoring circuit 4 A input these output voltages A 3 A and A 4 A, and calculate the battery 7A, 8A, 9A, and 10 A based on the input voltages A3A and A4A. Charge current, discharge current, and individual battery voltage, so that the remaining energy of the battery can be calculated. Moreover, the microcomputer 6 A performs on / off control of the switching elements 1 2 A and 1 3 A according to the state of the battery (normal, overcharge, overdischarge, and overcurrent). In this way, the microcomputer 6 A shoulders the protection function (overcharge protection, overdischarge protection, and overcurrent protection) in the battery device 2 2A. It is necessary to provide a constant voltage to the microcomputer 6 A. As a power source, the microcomputer 6 A is an important part of the structure, as described above. For example, common voltages 値 are 3.5V and 5.0V. The power of the battery condition monitoring circuit 14 A is generally supplied by the total battery voltage E 2 A of the batteries 7A, 8A, 9A, and 10A. As the total battery voltage E 2 A of the battery changes with the state of the load 2 0 A connected between the positive terminal 15 A and the negative terminal 17 A, a regulator 1 A controls the total battery voltage E 2 A of the battery to 3.3V, 5.0V, or other, so that a constant voltage E4A is applied to the microcomputer 6A. However, even if the constant voltage E 4 A is generated by the regulator 1 A and applied to the microcomputer 6 A, if the battery device 2 2 A continues the discharging operation, the total battery voltage E 2 A of the battery becomes low. Therefore, there is a situation in which the constant voltage E 4 A generated by the regulator 1 A is lower than the microcomputer 6 A. The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 cm) ΓΓ] (Please read first Note on the back then fill in this page) !! 1 order-! Line (printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6 116 7 at B7 V. Description of Invention 6) Voltage for stable operation. In the worst case, a phenomenon commonly known as microcomputer 6 A & runaway occurs. If the microcomputer 6 A runs away, since all control operations are not performed, including the opening / closing operation of the switching elements 1 2 A and 1 3 A, the safety of the battery device 2 2 A is not guaranteed at all. As usual, the voltage detection circuit 2 A is connected to the power supply of the microcomputer 6 A, and the microcomputer 6 A will not run away. The voltage detection circuit 2 A is composed of, for example, a comparator and a reference voltage, and is designed to change its output voltage when the input voltage becomes a specific set voltage. In FIG. 2, when the output voltage 4A of the regulator 1 A becomes lower than a specific set voltage (a reset detection voltage), the output of the voltage detection circuit 2 A goes from high to low. When the output of the voltage detection circuit 2 A changes, the microcomputer .6 A stops operation to prevent malfunction. This control method is called & reset ". The reset detection voltage of the microcomputer is the minimum operating voltage of the microcomputer 6 A without failure (runaway), and usually in the case of a 5 V input microcomputer, the reset detection voltage is set to about 4 · 6 V. Then, when the supply voltage of the microcomputer 6 A increases so that it can be operated again, the signal input to the microcomputer 6 A needs to be initialized once (hereinafter referred to as * power supply management #). To this end, a power-supply management circuit is placed on one of the input signal lines connected to the microcomputer 6A. After the microcomputer 6A starts operating, the power-supply management is performed only for a predetermined period. In this case, the operation of the power supply management circuit of the power supply management circuit needs to be compared with the time when the microcomputer 6 A starts to operate. If the operation of the microcomputer is not synchronized well with the power supply, it may cause a malfunction. In this case, the microcomputer falls into an inoperable state, so the safety of the battery pack cannot be guaranteed. Therefore, the power supply communication circuit needs the paper size to comply with the Chinese National Standard (CNS) A4 specification (210 X 297 mm). --- 1 ----- Order --------- line 6'r (Please read the precautions on the back before filling out this page) -6-46 1167 A7 .___ I_ B7_ V. Description of Invention 4) Be sure to operate. However, in order to synchronize the operation of the power supply management circuit with the operation of the microcomputer, it is necessary to constantly monitor the operation of the microcomputer, which causes a problem, that is, the circuit structure becomes complicated. Due to the increase in cost caused by the power communication circuit provided in this way, in many cases, in ordinary battery monitoring circuits and battery packs, the power communication circuit is usually replaced by the initial function of the microcomputer 6A itself. However, in this case, it is necessary to use a microcomputer that is safe in the initialization function, causing a problem that the choice of the microcomputer is limited. In view of the above, the object of the present invention is to solve the above problems of the prior art, and to provide a battery status monitoring circuit and a battery pack, which are highly safe and inexpensive. In order to solve the above problems, according to the present invention, a battery status monitoring circuit and a battery device are configured: when the microcomputer stops at a low supply voltage, or when the supply voltage of the microcomputer rises from a low voltage (for example, after the supply voltage is In the case where the detection voltage is set to rise once when the detection voltage is low, and when the supply voltage rises from 0 V, etc.), the charger is connected when it is known that the switching element is turned off, and the supply voltage of the microcomputer becomes sufficiently high After the microcomputer can operate normally at a voltage (the supply voltage reaches the reset release voltage is higher), the microcomputer sends a command signal to turn on the switching element, thereby turning on the switching element. Specifically, the battery status monitoring circuit is configured with a switching element connected in series with the charging / discharging circuit to respond to the switch control signal and open / close the charging and discharging circuit; a microcomputer is used to control the respective parts' and output and Switch control signal is equivalent to a control signal; a supply voltage detection circuit

Description of invention (11) " Communication with computer Functions and control functions of individual circuit blocks " A serial / parallel conversion circuit 39 shown in Fig. 6 converts a serial data signal DA (from a microcomputer 6) into a parallel data signal D5 to DO, and A logic circuit 40 converts these parallel data signals into control signals B1, B3, B4, F1, F2, and Η, and outputs them to the respective circuit blocks. The communication signal from the microcomputer 6 is composed of, for example, a certain clock signal τ K and a serial data signal D Α. As shown in FIG. 7, when the timing clock signal T K is at a high level, the serial data signal DA is One of the command signals sent by the microcomputer. In the example of Fig. 7, a command is composed of a series of 6-digit data.

The output of the analog signal A N is designed in response to the signals T K and D A ′ of the microcomputer 6 to select any one of the charging current, the discharging current, and the respective battery voltage. The "data reset function" of the control circuit 5 sets all the parallel data signals D 5 to D 0 of the serial / parallel conversion circuit 39 shown in FIG. 6 at a signal RS (initializes the data in the control circuit 5) by a signal RS. This signal RS changes when the output voltage E 4 of the regulator 1 in FIG. 1 is lower than the reset detection voltage of the microcomputer 6. Then, in the initialization state, the logic in the logic circuit 40 of FIG. 6 is designed to turn on and off the switching elements 12 and 13 (these control the charging and discharging operations shown in FIG. 1). When the "data reset function" of the control circuit 5 is executed, the input signal AN of the microcomputer 6 becomes a low level. This state remains until the output voltage E 4 of the regulator 1 exceeds the reset detection voltage of the microcomputer 6 again. 俾 The microcomputer 6 starts operation and requests specific data.

Even if the data request function of the microcomputer 6 fails and is not operated, the input signal A N maintains its current low state. Therefore, there is no case where the microcomputer 6 inputs the wrong input signal A N and fails ′, and therefore, the safety of the battery pack is improved. That is, in the present invention, the signal RS can simultaneously control the reset of the microbrain 6 and the power supply communication of the input signal AN.

Description of the invention (14) Device 2 2 'Even if the microcomputer 6 stops or fails, in the case of a low supply voltage when the microcomputer 6 stops, or when the supply voltage of the microcomputer 6 becomes In the case of a low voltage rise (for example, in the case where the supply voltage has risen from below the reset detection voltage_ once, the situation in which the supply voltage of the microcomputer 6 has risen from 0 V, etc.), the reset is performed by the voltage detection circuit 2 To open the switching elements 1 2 and 1 3. Then, after the charger 21 is connected and the supply voltage E 4 to be supplied to the microcomputer 6 rises, 俾 becomes a voltage at which the microcomputer 6 can operate normally or higher, a command signal is sent from the microcomputer 6 to the control circuit 5, 俾Turn on the switching elements 12 and 13. For example, in the example of FIG. 8, the microcomputer 6 sends a command signal " 1 0 1 1 1 " to the control circuit 5 to turn on the switching elements 12 and 13 for the first time. Since the above operations keep the switch elements 12 and 13 open until the microcomputer 6 sends a command to turn on the switching elements 12 and 13, the state of being unable to charge or discharge can be maintained continuously, even if, for example, the microcomputer 6 Stops or fails, even when no control is performed. "This way, even if the microcomputer 6 stops or fails, the battery device 2 2 can be secured. Moreover, when the microcomputer 6 recovers from the self-reset state, since the switching elements 12 and 13 start from the off state and the microcomputer 6 is completely stable, the switching elements 12 and 13 are turned on, thereby eliminating the power loss. Charging current or discharging current, thereby improving the accuracy of the remaining energy calculation of the battery. The operation of this embodiment will be described later with reference to FIGS. 9 and 10. Fig. 9 shows the operation timing of this embodiment.

Description of the invention (15) (Please read the notes on the back before filling this page) During the period from 0 to ta, the battery device 2 2 supplies a current to the load 2 〇, and the total battery voltage decreases with the passage of time. At time ta, the total battery voltage becomes the same as the output voltage of the regulator 1. At time taa I, the output voltage of the circuit breaker 1 reaches the detection of the voltage detection circuit 2. Measure the voltage (the reset detection voltage of the microcomputer). At this time, the output voltage of the voltage detection circuit 7 is changed as much as S to reset the microcomputer 6, and also reset the control circuit 5, and reset the input signal AN of the microcomputer 6 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and then, at time tb, the charger 21 is connected. In the battery device 2 2 structured as shown in FIG. 1, once the charger 21 is connected, the charger Higher voltage or total battery voltage The voltage is applied to the input terminal of the regulator 1. If the voltage of the charger 2 1 is higher than the required output voltage of the regulator 1 (such as 3.3 V or 5 V), once the charger 21 is connected, the voltage is adjusted. The regulator 1 supplies the required constant voltage (such as 3.3V or 5V) to the microcomputer 6. The voltage detection circuit 2 monitors the output voltage of the regulator 1, and if the output voltage of the regulator 1 becomes the voltage at which the microcomputer 6 normally operates ( When the resetting voltage of the microcomputer 6 is released (or higher), the output RS of the voltage detection circuit 2 is reversed and the microcomputer 6 starts to operate. At this time, the input signal AN is still maintained at a low level. Then, the microcomputer 6 is self-diagnosed Knowing that it is normal, the microcomputer 6 sends a specific data request command to the control circuit 5 at time tc. The control circuit 5 sends data to the current monitoring circuit 3 and the battery voltage monitoring circuit 4 after processing the signal. In the case of data, the current monitoring circuit 3 and the battery voltage monitoring circuit 4 then output corresponding data to the control circuit 5. First, upon receiving the data, the control circuit 5 outputs a specific signal AN to the microcomputer 6.

Description of the invention (16) After the stable operation is achieved, the power supply is released automatically, so it improves The accuracy of the remaining energy calculation of the sub-tank. Fig. 10 shows the operation flow of Fig. 9. At time ta, from the supply current to the load, the total battery voltage becomes the same as the output voltage of the regulator, and thereafter, the discharge operation is performed. When the output voltage of the regulator 1 becomes the detection voltage (reset detection voltage) of the voltage detection circuit 2 or lower at time taa, the reset signal RS changes from a high level to a low level. The microcomputer 6 resets according to the reset signal RS, and at the same time, the control circuit 5 resets, so that the input signal A N is reduced. Thereafter, when the charging circuit 21 is connected, since the voltage of the charger 21 (higher than the total battery voltage or one of the regulator's required voltages) is applied to the input of the regulator 1, the regulator The output voltage of 1 becomes the reset release voltage or higher (to the required voltage). Thereafter, the microcomputer 6 returns to the reset state to perform self-diagnosis. If the self-diagnosis result of the microcomputer is N G, since the microcomputer 6 has not sent a command requesting specific data, the input signal A N is maintained at a low level. If the self-diagnosis result of the microcomputer 6 is 0 K, the microcomputer 6 sends a command requesting specific information to the control circuit 5. At this time, if no command is sent, the input signal A N is maintained at a low level, and if the command is sent, the input signal A N becomes a specific frame corresponding to the data request. FIG. 11 is a block diagram showing another embodiment of the present invention. In this embodiment, the microcomputer 6 is constructed as a component different from the battery condition monitoring circuit 14.

In the embodiment shown in FIG. 11, a plurality of microcomputers 6 can be combined together. For example, when the microcomputer 6 is reset and restored once, an unstable input signal A N is maintained, even if a microcomputer that has not started operation is selected, there is no inconvenience in the present invention. The present invention is very effective because the range of microcomputers selected in this way is wide. In the embodiment mode shown in Figs. 1 and 11, an example of a structure is described, in which the respective storage batteries 7 to Γ 0 are connected in series. However, the present invention can also be applied to a case where a plurality of batteries are connected in parallel. According to the present invention, even if the microcomputer 6 is integrated with other circuit blocks (a die), it is difficult for the microcomputer 6 to be distinguished from other circuit blocks, but it has the function of monitoring the battery voltage, charging current, and discharging current of the storage battery, and thus The circuit block that calculates the remaining energy of the battery and other information is also suitable for microcomputers.
