成し充電が開始される。Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows the basic structure of the secondary battery pack of the present invention. In the figure, 2 is a positive terminal for charging, 3 is an identification signal receiving terminal, 4 is a negative terminal for charging, 5 is a switch section having electrical or mechanical contacts for forming a battery charging circuit, 6
Is an identification signal receiving unit, 7 is a secondary battery, and the battery pack 8 includes a secondary battery including one cell to a plurality of cells and a terminal,
Each of the above-mentioned elements such as a switch unit is packaged in one. When the secondary battery pack is combined with the dedicated charger, the identification signal from the dedicated charger enters the identification signal receiving unit 6 through the identification signal receiving terminal 3. The switch unit 5 operates only when a unique identification signal is input to the battery pack, and a charging circuit is formed in the battery pack. FIG. 4 shows a specific example thereof. As shown in FIG. 4A, when a voltage (V) is applied to the identification signal receiving terminal, the relay 9 operates and the relay contact 10 thereof closes. Therefore, a charging circuit is formed in the pack, and charging of the battery is started from the dedicated charger. The switch unit 5 may be an electric switch other than a relay, for example, as shown in FIG.
Alternatively, a switching element (FET) may be used to turn on and off as shown in FIG. The input applied to the identification signal receiving terminal 3 may be in the form of current (I) as well as voltage (V). At that time, as shown in FIGS. 4C and 4D, current is converted into voltage in the battery pack, and the switch unit 12 is controlled by the output. As the identification reception signal, not only the DC voltage but also the AC voltage as shown in FIG. 5, the switch circuit 12, the capacitor 13, the signal detection circuit 14,
A charging circuit can be realized by configuring the control circuit 15. In this case, the switch is closed only when a specific frequency is detected. FIG. 6 (a) is considered as this development. The switch circuit 18 is closed only when a specific pulse is applied to the battery pack from the dedicated charger. Here, the specific pulse means a combination of the number of pulses and the pulse width (including the modulation factor) confirmed by the pulse counter circuit 19 of the battery pack. Note that the identification signal receiving terminals of the dedicated charger and the battery pack are most commonly contacted directly as shown in FIG. 6 (a), but are separated without contact as shown in FIG. 6 (b). May be. The example shown in FIG. 6B shows a transmission / reception method using an LED, a photodiode, and a phototransistor. As the wavelength of light, visible light and infrared light can be assumed, and the light emission signal of the LED on the dedicated charger side is converted into an electric signal by a light receiving element such as a phototransistor on the battery pack side to drive the switch circuit. By specifying the wavelength of the light to be used, it is possible to identify (by color) the combination of the LED and its light receiving element. The form of transmission and reception is not limited to continuous lighting, and intermittent signals (pulse signal and modulation signal) are also possible. L controlled by the pulse control circuit 20 shown in FIG.
The light emission signal of the ED is converted into an electric signal by a light receiving element such as a phototransistor on the battery pack side, and the pulse counter circuit is operated to drive the switch circuit. Figure 7
(A) shows an example of a combination of the magnet 21 and a magnetic sensor, for example, a reed switch 22. The magnet 21 is embedded in a part of the fitting portion of the battery pack of the dedicated charger, and when the battery pack is fitted to the charger, the reed switch 22 is closed and the relay 23 is operated, and the relay contact 24 is closed to close the battery. A charging circuit is formed. A similar operation can be realized by using a Hall element for the reed switch. FIG. 7B shows a specific configuration example of the battery pack and the charger. 25 is a dedicated charger, 26 is a magnet embedded in a part of the fitting part,
27 is a battery pack, 28 is a reed switch provided corresponding to the magnet 26, or a hall element. By fitting the battery pack 27 into the dedicated charger 25, the reed switch 28 is turned on, and the battery pack is charged. Several combinations can be considered for the position, size, and number of the magnets 26 here. The magnet used may be not only a permanent magnet but also an electromagnet. Further, as the form of magnetic force, in addition to continuous magnetic force, it is also possible to perform pulse-like input using a pulse control circuit and a counter shown in FIG. The mechanical rotation of can be considered. Further, as a configuration in which the identification signal receiving terminal is separated from the charger side in a non-contact manner, a sound wave sensor as shown in FIG. 7D may be used. The form of the sound wave signal at this time may be a continuous signal or an intermittent signal form. As the form of the battery identification signal of the secondary battery pack, the form of the control signal from the dedicated charger to the battery pack can be applied as it is. That is, an electric signal such as DC / AC / pulse, a continuous or intermittent optical signal, a continuous or intermittent magnetic signal, or a sound wave signal can be considered. Specifically, for example, as the magnetic signal, a configuration in which the magnet 26 and the reed switch 28 are exchanged in position in FIG. 7B can be considered. That is, the magnet incorporated in the battery pack operates the reed switch or hall element incorporated in the dedicated charger, and then the identification signal is output from the dedicated charger to the battery pack, and the signal forms the charging circuit in the battery pack. To be done. This is shown in FIG. As a configuration using a magnetic signal, there is also a method in which a magnetic card or a magnetic seal is provided on the battery pack side and the signal is read on the dedicated charger side using a magnetic card reader. This is also a configuration in which the battery pack has an ID code. In addition, an example using an optical signal is shown in FIG.
Shown in. An LED light emission signal from the battery pack is detected by a photosensor or phototransistor on the dedicated charger side, an identification signal is sent from the control output circuit of the charger to the battery pack, and the switch circuit is closed. Further, as an application example of a photo interrupter that intermittently signals, FIG.
There are (b), (c), and (d). For example, in a dedicated charger, the LED output is always
It is assumed that it is detected by the interrupter. Figure 9
By fitting the battery pack as shown in (a), L
The ED output is no longer detected and becomes the detection signal for the battery pack. Further, as shown in FIG. 9C, by providing the light reflecting portion 36 on the battery pack, the battery pack is fitted and the light reflecting portion 36 functions, and the LED output is detected for the first time as shown in FIG. 9D. It is also possible to adopt a configuration as described above.
The following examples are examples of configurations in which the battery pack has an ID code. In FIG. 10, the battery pack has an ID code such as a read-only memory: ROM, and the charger reads the ID code, and only when the ID code matches, the control output is output from the charger and the battery pack The switch circuit of the charging circuit is closed. A bar code can also be used as the ID code. Figure 11 shows the bar code 4 on the battery pack.
The information of 0 is read by the barcode reader 41, and the switch circuit is closed only when the set value and the information of the barcode match. Further, as shown in FIG. 12, it is possible to set a battery pack identification code or an ID code as color information in the combination of the color mark 42 and the color mark sensor 43. The case where the battery pack has the battery identification signal is summarized as shown in FIG. In the figure, 44 is a positive terminal for charging, 45 is an identification signal receiving terminal, 46 is a battery identification signal transmitting terminal, 47 is a negative terminal for charging, and 48 is a switch section having electrical or mechanical contacts for forming a battery charging circuit. , 49 is an identification signal receiver, 50
Indicates a battery identification signal transmission unit, 51 indicates a battery, and 52 indicates a battery pack in which all of them are packaged. The dedicated charger receives the battery identification signal unique to the battery pack and, if the battery identification signal is correct, sends back the identification signal unique to the battery pack. The battery pack further judges the identification signal,
If it is finally correct, the switch unit is closed, a charging circuit is formed, and charging is started.
