[Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a schematic view showing the circuit configuration of one battery pack constituting the secondary battery system of the embodiment of the present invention. In Fig. 1, 'the symbol 100 denotes a battery pack, 110 denotes a control controller, CL denotes a secondary battery unit' SW denotes a discharge switch, and R2, R3 denotes a resistance ' ΤΙ, T2, T3, T4 denote a connection terminal, 2〇 〇 indicates an electronic machine. The power switch controller sw that is charged in the secondary battery unit cl of the battery pack 100 is controlled to perform the power switch 200 of the 〇N/〇FF to supply power to the electronic device 200, particularly in the present invention.作为 Use the secondary battery (four) in parallel with multiple numbers as the target. The control controller 11 configured by a microcomputer or the like has an N_ch open-circuit output port, an A/D conversion input port, and an input port, and discharge switches are performed according to inputs from the ports, etc. The ON/OFF of the SW controls the power supply to the electronic device 200. Control controller 11 〇 Ν 外 外 外 外 外 外 外 ^ ^ ^ ^ ^ 汲 汲 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 098 The signal of the discharge (switch) state of the pool group. In addition, the A/D conversion input port of the control controller 110 has a function of taking a signal of the battery pack discharge (_) state of the human face in a certain period. In addition, the control unit (four) 丨i 输 输 输 输 输The function is to confirm the connection between the battery pack and the company. If the battery is not connected to the local economy, the discharge switch will be turned off, and the signal input cycle of the A/D conversion input port will be slowed down, or (4) H The action stops. This function is used to suppress the power consumed inside the battery pack. The battery pack 100 is provided with four connection terminals T1 to D4, and these terminals are connected to the electronic device 200. The connection terminal T1 is a power supply terminal (BATT + ), the connection terminal T2 is a discharge control field terminal, the connection terminal Τ3 is a battery connection signal terminal, and the connection terminal Τ4 is a ground terminal (GND). The discharge control signal input from the connection terminal Τ2 is boosted by the resistor R2 in the battery pack 1 and branched into two to be input to the control controller 110. Among the two branches, one of them is connected to the N-bias via the resistor R1: the output port is connected, and the other one is directly connected to the A/D conversion port. The discharge control signal of the battery pack 1 that discharges causes the N-ch and the pole output port to be in the Low state. In this way, the action = ON is used to notify that the battery is being discharged from the battery pack itself to the other battery. The group ',, and connected to the battery connection signal is boosted by the resistor R3 in the battery pack 100 098132438 n 201112562 The input port of the control controller 110. Next, a secondary battery system in which the battery pack 100 of the above-described manner is connected in parallel will be described. Fig. 2 is a schematic view showing the circuit structure of a secondary battery system according to an embodiment of the present invention. Fig. 2 shows that the secondary battery system is constituted by the parallel connection of two battery packs. In Fig. 2, for simplification, the battery pack 1 is indicated by 1 , and the battery pack 2 is indicated by 1 〇〇. Each battery pack is the same battery pack as shown in the figure. The main body side discharge control signal line of the main circuit side of the electronic machine H 2GG is connected to the discharge control signals from the battery pack i and the battery pack 2, and is boosted by the resistor R4. When the battery pack is connected to the main body side connecting circuit of the electronic device 2, the terminal T3 for connecting the nickname of the battery is connected and connected, and when the electric body and the main body are connected to the circuit, the operator is smashed. The battery is connected to the U Tiger! The level becomes the level of 'the standard' so that the control controller can recognize that the battery pack is connected to the body. °曰 The person explains the discharge control signal line of the secondary battery system shown in Figure 2. Fig. 3 is a view showing the secondary battery system of the embodiment of the present invention: the discharge control k-line is extracted. To be more specifically shown, in Fig. 3, the resistance value of the resistor associated with the discharge control signal line is calculated as R1 = 1 〇 Ki2, R2 = 1 〇 Mn, and R4 = = i. Fig. 3(A) shows the state in which the battery pack is not discharged, and ® 3 (B) indicates that the battery is in a state of being discharged, and 胄 3 (C) indicates the state in which the battery is discharged. In the case of Fig. 3 (A) in which the king F is not discharged, the N, ch, and the gates are open at 4, and the 5 volt booster does not appear to be the same. Therefore, the discharge control signal line The voltage becomes 5V. In the case of Figure 3 (B) of one of the battery packs being discharged, the terminal of the N-ch open-circuit output port becomes the LOW level, that is, connected to GND. The total of the step-up resistors is 9.9 ga, and the step-down resistance is 10 Ω, so the voltage of the discharge control signal becomes about 2.5 volts. In the case of Fig. 3(c) in which two of the battery packs are discharging, the duty of the step-down resistor is two parallels, so the total is (10). The total of the boost resistors is 9.98 Ω, and the discharge control signal line is 1.66 volts. As described above, according to the configuration of the present invention, when the battery pack in the discharge state is increased, since the voltage of the discharge control line is lowered, it is easy to grasp whether the battery pack is being discharged or not (10) or more Each battery pack is discharging. The basic operation of the controller U) for the secondary battery (fourth) of the embodiment of the present invention will be described.
