    Abstract: A battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). An analog circuit (12) and a microcomputer (11) inside the battery pack (1) detect an ON/OFF state of the external device (9) and execute control in such a manner as to effect charging by the balance of power obtained by subtracting the maximum power consumption of the external device (9) from the total capacity of the power supply circuit (10) under the ON state and to effect charging by full use of the supply power from the power supply circuit (10) under the OFF state. This charge/discharge control is executed when the microcomputer (11) makes ON/OFF control of a charging switch (S1), a discharging switch (S2) and a switch (S4).

    Abstract: The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).

    Abstract: PROBLEM TO BE SOLVED: To prevent direct short-circuiting of a positive electrode and the negative electrode, and to avoid the spread of the internal short circuit, by forming a porous heat resisting layer on the active material of the positive electrode and/or the negative electrode, in a nonaqueous electrolyte secondary battery. SOLUTION: In a nonaqueous electrolyte secondary battery, porous heat resisting insulation layers 20 are formed on both surface of the negative electrode active material of a negative electrode collector 7, and it is cut to make into a negative electrode. And a positive electrode having positive electrode active material layers 4 on both surfaces of a positive electrode collector 5 is also obtained. The negative electrode and the positive electrode are laminated through a separator 8, and the laminated body is wound numerous turnes in a spiral form, and an insulating sheet is wound on the outermost periphery so as to form an electrode spiral body. The porous heat resisting insulation layer 20 was provided on the negative electrode active layer 6, but it may be provided on the positive electrode active material layer 4, or on both layers 4 and 6. Consequently, even though an external heating, or a heating by an external shock is generated, the insulation can be maintained between the positive electrode and the negative electrode, and as a result, an advantage of not short- circuiting the electrodes at a large area can be obtained.

    Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a separator arising when a battery is compressed and avoid internal short circuit by using a separator formed by stacking a first separator having the specified porosity and a second separator also having the specified porosity. SOLUTION: In a stacked electrode body formed by stacking a belt-shaped negative electrode and a belt-shaped positive electrode through a separator, a laminated separator prepared by stacking a first separator having a porosity of 30% or more but less than 50% and a second separator having a porosity of 50% or more but less than 90% is used. When a battery is compressed by the outside force, the second separator having high porosity is compressed at first, the compression force is relaxed, and the compression force is hardly applied to the first separator. The complete break down of the first separator is prevented, the insulation between the positive electrode and the negative electrode is kept, and internal short circuit can be avoided.

    Abstract: PURPOSE: To provide a small size and low cost battery protection circuit. CONSTITUTION: The voltage determination apparatus 11 of a voltage detection circuit 3 detects the battery voltage of a secondary battery 1. When the voltage is already at a full charge voltage, the terminal voltage of the positive terminal side of the secondary battery 1 is output to the comparator 31 of a control circuit 5. When the voltage is not yet at the full charge voltage, the terminal voltage of the negative terminal side of the secondary battery 1 is output to the comparator 31 of the control circuit 5. The voltage determination apparatus 21 of a voltage detection circuit 4 detects the battery voltage of a secondary battery 2. When the voltage is already at a full charge voltage, the terminal voltage of the positive terminal side of the secondary battery 2 is output to the comparator 32 of a control circuit 5. When the voltage is not yet at the full charge voltage, the terminal voltage of the negative terminal side of the secondary battery 2 is output to the comparator 32 of the control circuit 5. The comparators 31, 32 compare these voltages with one half of the battery voltages of the secondary batteries 1, 2 so as to turn off an FET 34 when the secondary battery is fully charged, and so as to turn on the FET 34 when the secondary battery is not fully charged.
