The controller 14, 64, 74, 86, 95, and 115 that can be applied to various electric appliances exemplified so far will be described in a basic range. The battery pack 400 is a slide-attached (box-type) battery pack 1, and the control content is substantially the same even when the stick-type battery pack 2 is used.

As shown in FIG. 55, the battery pack 400 is provided with positive and negative power supply terminal receiving portions 401, 402 and three communication terminal receiving portions 403, 404, 405. In addition, a remaining capacity display unit 406 for displaying the remaining capacity of the LED with an LED is provided on the lower surface of the battery pack 400. The battery pack 400 includes a remaining capacity detection circuit 407 and three battery cells V1, V2, and V3. An output voltage of 10.8 V is secured by the three battery cells V1, V2, and V3. The battery pack 400 includes a thermistor 408 that detects the temperature of the battery cell V1.

The thermistor 408 is generally an NTC thermistor having a negative resistance temperature characteristic, but a PTC thermistor having a positive characteristic may be used. Further, in the present embodiment, the thermistor 408 is illustrated in the vicinity of the battery cell V1 in order to appropriately detect the temperature of the battery. However, instead of this, the thermistor 408 is disposed in the vicinity of the battery cells V2, V3. It is good. When there is a large temperature difference between V1, V2 and V3, it is desirable to arrange the thermistor in the battery cell where the temperature is most likely to rise.

Even when the battery pack 400 is removed from the battery mounting portion of the electric appliance, the remaining capacity can be confirmed by the remaining capacity display unit 406. The remaining capacity display unit 406 displays four lights using LEDs 1 to 4. When the user depresses the remaining capacity switch 409 (remaining capacity switch 1k shown in FIG. 5), the remaining capacity detecting circuit 407 turns on the LEDs 1 to 4 according to the remaining capacity. In the remaining capacity detection circuit 407, the remaining capacity is detected according to the battery voltage, and control is performed to switch the number of lights, for example, 1 lamp, 2 lamps, 3 lamps, 4 lamps, every 25 percent.

The positive and negative power supply terminal receiving portions 401 and 402 of the battery pack 400 and the battery cell temperature detecting terminal receiving portion 405 among the three communication terminal receiving portions 403, 404 and 405 are electrically connected to the battery mounting portion side of the electric appliance. Is done. The battery cell temperature detection terminal receiver 405 corresponds to the central communication terminal receiver 1d in FIG. Of the three communication terminal receivers 403, 404, and 405, the battery cell voltage detection terminal receivers 403 and 404 are charger terminal receivers and are connected only to the charger. The electric appliance 300 includes a heat conversion unit 301 that converts electric energy into a heat source of the electric appliance, a power supply circuit 302, a control microcomputer 303, a battery state detection unit 304, an energization control switch (FET) 305, A drive circuit 306, a main switch 310, a strength switch 311 and a current detection circuit 315 are mounted.

When the battery voltage is input, the power supply circuit 302 steps down the battery voltage to a control voltage Vcc having a predetermined voltage value and outputs it. The control voltage Vcc generated by the power supply circuit 302 is used as an operation power supply for each unit such as the control microcomputer 303 and the drive circuit 306.

The control microcomputer 303 is a microcomputer provided with a CPU, ROM, RAM, I / O, and the like.

In the battery state detection unit 304, the battery voltage detection circuit 316 detects the battery voltage input from the power supply terminal receiving unit 401 of the battery pack 400 and the positive electrode terminal 312 of the electric device, and inputs the battery voltage to the control microcomputer 303. The battery temperature detection circuit 314 detects the resistance value of the thermistor 408 via the communication terminal receiver 405 and the communication terminal 317 that are connected to each other, whereby the resistance value detection value of the thermistor 408 is input to the control microcomputer 303. Note that the characteristics of the thermistor 408 are stored in advance in the ROM of the control microcomputer, and the control microcomputer can detect the temperature of the battery cell from the input resistance value of the thermistor 408 and the characteristic data stored in the ROM. it can.

The current detection circuit 315 can detect an energization current value from, for example, a potential difference generated at both ends of a current detection resistor by an energization current flowing when the electric appliance is operating.

In the present embodiment, the energization control switch 305 uses an N-channel MOSFET, and the power supplied to the heat conversion unit can be controlled by the drive circuit 306 controlling the on / off duty ratio.

The main switch 310 is configured to input to the control microcomputer 303 whether or not the switch is on. The strength switch 311 indicates that the switch is on when it is desired to operate in the strong mode, for example. When it is input to the control microcomputer 303 and it is desired to operate in the weak mode, it is input to the control microcomputer 303 that it is in the off state. In the present embodiment, the main switch 310 and the strength switch 311 are separated from each other. For example, a single switch is used to switch between strong, weak, and stop according to the number of times the switch is turned on. Also good.

FIG. 56 shows a flowchart for the operation control performed by the control microcomputer 303 and mainly for protecting the discharge of the battery pack 400. When the battery pack 400 is attached to the battery attachment portion of the electric appliance 300, power is supplied to the electric appliance 300 and the control microcomputer 303 operates. Thereafter, when a signal indicating that the user has turned on the main switch 310 is input to the control microcomputer 303 (step 01, hereinafter abbreviated as “ST01”), the control microcomputer 303 first transfers the battery from the battery state detection unit 304 to the battery in ST02. Get the status. The battery state is the battery voltage and the battery cell temperature as described above. Based on the acquired battery state, a start permission condition is determined in ST03. In this case, when the voltage of the battery pack 400 is 8 V or higher and the temperature is 60 ° C. or lower, it is determined that the start permission condition is satisfied. If it is determined that the activation permission condition is not satisfied, the flow is terminated in ST05, and the electric appliance 300 does not start the operation even if the main switch 310 is turned on.

If it is determined in ST03 that the activation condition is satisfied, whether or not it is the strong mode is confirmed in ST04. The on / off duty ratio (Duty) of the drive circuit 306 is changed according to the switching state of the strength switch 311, and the power supplied to the heat conversion unit 301 is controlled by the energization control switch 305. When the strong mode is confirmed in ST04, 100% duty power is supplied to the heat conversion unit 301 in ST06. If the strong mode is not confirmed in ST04 and it is determined that the mode is the weak mode, power of 50% duty is supplied to the heat conversion unit 301 in ST07.

Battery status is acquired in ST08 while power is being supplied (electric appliance is in use). Similar to the processing in ST02, the battery voltage detection unit 304 detects the battery voltage and the battery cell temperature. The control microcomputer 303 acquires the detected battery voltage and battery cell temperature from the battery state detection unit 304. Furthermore, since an energizing current flows during power supply, the energizing current value is also detected by the current detection circuit 315. The control microcomputer 303 acquires the detected energization current value from the current detection circuit 315.

Based on the battery state acquired in ST08, it is determined in ST09 whether the electric appliance stop condition is satisfied. The stop condition is, for example, that the voltage of the battery pack 400 is detected to be 7.5 V or less for 1 second or longer, the temperature is detected to be 80 ° C. or higher for 1 second or longer, and the energizing current is 80 A or higher. It is set to be detected for more than a second. When one of these conditions is detected, the energization control switch 305 is turned off in ST11, and the electric appliance 300 is stopped even if the main switch 310 is on.

Since this type of battery pack 400 is used for an electric tool or an appliance that flows a large current, the battery pack 400 tends to be in a high temperature state. Therefore, when the battery pack 400 reaches a high temperature state, it is necessary to stop discharging and prevent the life from being shortened. Therefore, the control microcomputer 303 of the electric appliance 300 reads the resistance value information of the thermistor 408 in the battery pack 400 via the T terminal 317, and turns off the energization control switch 305 when the battery temperature exceeds a specified value (for example, 80 ° C.). To cut off the power supply.

In addition to the above high temperature protection, over discharge protection is provided. In order to prevent overdischarge, the battery voltage detection circuit 316 performs measurement so that the discharge is stopped when it is detected that the voltage of the battery pack 400 has fallen below the specified value. In the case of a 10.8 V battery, the cell voltage to be protected is 2.5 V × 3, and when the voltage falls below 7.5 V, the electric appliance is stopped. However, since a large current may flow instantaneously due to an inrush current or the like in an electric appliance and the remaining capacity of the battery pack may not be empty, it may fall below 7.5V for an instant, so the detection time is, for example, 1 It is desirable to have a width of about a second.

In order to prevent a sudden temperature rise of the battery pack 400, the current value is detected by the current detection circuit 315 so that the battery pack 400 stops when detecting not only the temperature but also an overcurrent exceeding a certain value. It should be noted that it is desirable that the detection time has a width so that it does not stop due to an inrush current at the time of startup or the like. Further, since not only the battery pack 400 but also the electric appliance itself continues to flow, it causes a failure. Therefore, the overcurrent protection of the battery pack 400 may be set with a current value that can be passed to the electric appliance side. .

When the above-mentioned protective functions are activated and the electric appliance is stopped, while the main switch 310 is kept on, a latch is provided so that the electric appliance does not operate. It is possible to prevent the instrument from resuming operation. Further, it is preferable that the start condition has a hysteresis with respect to the stop condition so that it does not stop immediately even if it operates. For example, it is desirable to perform control to stop at 7.5 V and start operation at 8.0 V, or control to stop at 80 ° C. and start operation at 60 ° C.

Also, not only the temperature of the battery cell but also the temperature in the electric appliance may be detected and stopped when it exceeds a certain value. For example, the thermistor of the heat conversion unit temperature detection circuit 308 is disposed in the vicinity of the heat conversion unit 301 so that the temperature of the heat conversion unit 301 can be detected. When the temperature of the heat conversion unit 301 is input to the control microcomputer 303 by the heat conversion unit temperature detection circuit 308 and the temperature of the heat conversion unit 301 becomes an abnormal state, the control microcomputer 303 determines that the stop condition of the appliance is satisfied. Then, the electric appliance may be stopped. At that time, the control microcomputer 303 may be configured to notify that there is an abnormality in the electrical device.

If any of the battery pack voltage detected by the battery state detection unit 304, the battery cell temperature, and the current value detected by the current detection circuit 315 does not satisfy the activation permission condition of the electric appliance or satisfies the stop condition of the appliance Alternatively, the LED 5 may be turned on to notify that the battery pack 400 is in a discharge disabled state.

If an abnormal current such as a short circuit occurs in the electric appliance 300 due to a short circuit and an excessive current flows, the battery pack 400 and the electric appliance may be damaged. Therefore, the battery pack 400 and the electric appliance are protected. Therefore, the fuse 320 may be mounted in the battery pack 400 or in the electric appliance. When the fuse 320 is mounted on the electric appliance 300 side as shown in FIG. 55, the battery pack 400 can be used even if the fuse 320 is blown, and therefore it is desirable to mount the fuse 320 on the electric appliance 300 side.

FIG. 57 shows a configuration of a battery pack 450 and an electric appliance 350 which are different from those in FIG. In this configuration, the power supply circuit 461 and the control microcomputer 454 are also configured in the battery pack 450. Further, a voltage monitoring circuit 460, a battery cell temperature detection circuit 456, and a current detection circuit 457 are also configured in the battery pack 450.

The power supply circuit 461 is used as a power supply for operation of each part in the battery such as the control microcomputer 454. The control microcomputer 454 is a microcomputer provided with a CPU, ROM, RAM, I / O, and the like. The voltage monitoring circuit 460 detects the voltages of the cells V1, V2, and V3 and inputs them to the control microcomputer. The temperature detection circuit 456 detects the battery cell temperature from the resistance value of the thermistor provided in the vicinity of the battery cell V <b> 1 and inputs it to the control microcomputer 454. The current detection circuit 457 detects an energization current that flows when the electric appliance is operating, and inputs it to the control microcomputer 454. When the remaining capacity switch 455 is turned on, a signal is input to the control microcomputer 454, and the control microcomputer 454 calculates the remaining battery capacity corresponding to the cell voltage and displays it on the remaining capacity display circuit (LED or the like).

The battery pack 450 is provided with positive and negative power terminal receiving portions 451 and 452 and communication terminal receiving portions 453 and 459, and the communication terminal receiving portions 453 and 459 are connected to the communication terminals 317 and 318 of the electric appliance 350. It is comprised so that. The control microcomputer 454 in the battery is configured to be able to receive a signal from the control microcomputer 303 of the electric appliance 350 via the communication terminal receiving part 453 and the communication terminal 317 (hereinafter referred to as connection part C). A signal can be transmitted to the control microcomputer 303 of the electric appliance 350 via the unit 459 and the communication terminal 318 (hereinafter referred to as connection unit D).

Similarly to the electric appliance 300, the electric appliance 350 includes positive and negative power supply terminals 312 and 313, communication terminals 317 and 318, a control microcomputer 303, a power supply circuit 302, an energization control switch (FET) 305, a drive circuit 306, and a main switch 310. A strength switch 311 is provided.

58 shows a flowchart of operation control on the electric appliance 350 side performed by the control microcomputer 303, and FIG. 59 shows a flowchart of operation control on the battery pack 450 side performed by the control microcomputer 454. The discharge protection of the battery pack 450 is mainly achieved by the operation control. When a signal for turning on the main switch 310 by the user is input to the control microcomputer 303 (ST21), the control microcomputer 303 first outputs a Hi level signal to the connection C (ST22).

The control microcomputer 454 starts operation control when a Hi level signal is input from the connection C (ST41), and acquires the battery state in ST42. The control microcomputer 454 individually detects the voltages of the battery cells V1, V2, and V3 from the voltage monitoring circuit 460, and detects the temperature of the battery cell from the temperature detection circuit 456. In ST43, control microcomputer 454 determines whether each voltage of battery cells V1, V2, and V3 and the battery cell temperature satisfy the activation permission condition of the device. In the configuration of FIG. 57, since the voltage of the battery cell can be detected individually, the activation condition is determined by whether or not the cell having the lowest voltage among V1 to V3 is 2.7V or more. The activation permission condition for the battery cell temperature is determined by whether or not the battery cell temperature is 60 ° C. or higher as in the configuration of FIG.

When the battery pack 450 satisfies the activation permission condition, that is, when it is determined that the device may be activated, the control microcomputer 454 outputs the connection portion D so that the potential of the connection portion D becomes a low level (ST45). If the activation permission condition is not satisfied, the operation is terminated (ST44).

When the control microcomputer 303 ends ST22, the control microcomputer 303 proceeds to ST23 and waits for 10 msec, for example. This time is the time until the control microcomputer 454 completes the processing from ST41 to ST45. Then, the process proceeds to ST24, and it is determined whether or not a low level signal is input from the connection portion D. Here, when a low level signal is not input from the connection portion D, the battery pack 450 determines that the activation condition is not satisfied, stops signal output to the connection portion C in ST25, and ends the operation in ST26. To do. When a low level signal is input from the connection portion D, the battery pack 450 determines that the activation condition is satisfied, and drives the electric appliance with a duty ratio corresponding to each (ST28, ST29).

The control microcomputer 454 moves to ST46 and acquires the battery state. Here, the voltage and the temperature of the battery cell are acquired from the voltage monitoring circuit 460 and the temperature detection circuit 456, and the energization current flowing through the electric appliance is acquired from the current detection circuit 457.

In ST47, it is determined whether the equipment stop condition is satisfied. The stop condition is, for example, that any one of the battery cells V1, V2, and V3 is detected to be 2.5 V or less for 1 second or more, and that the temperature is 80 ° C. or more is detected for 1 second or more. It is set that 80 A or more is detected for 1 second or more. When one of these conditions is detected, the output to the connection part D is stopped in ST48, and the operation is terminated (ST49). If these conditions are not detected, the process proceeds to ST50.

In ST50, it is determined whether or not a signal from the connection section C is input. If a signal is input, it is determined that the main switch 310 of the electric appliance remains ON, and the process returns to ST46. When the signal from the connection part C is not input, it judges that the main switch 310 of the electric appliance was turned off, and transfers to ST48 in order to complete | finish operation | movement.

When the control microcomputer 303 starts driving the device to ST28 and ST29, it determines whether or not the Low level signal from the connection unit D is input in ST30. If the signal is input, it is determined that the battery does not satisfy the device stop condition, and the process proceeds to ST32. It is determined whether or not the main switch 310 is turned off. If the main switch 310 is not turned off, the process returns to ST27 and the same operation is repeated.

When the signal from the connection part D is not input in ST30, or when the main switch 310 is turned off in ST31, the process proceeds to ST32 to stop the output of the Hi level signal to the connection part C, and in ST33. End the operation.

In this way, in the configuration as shown in FIG. 57, by communicating the ON state of the main switch 310 at the connection portion C and whether or not the battery may be discharged at the connection portion D (discharge permission information), FIG. Similarly, discharge protection of the battery can be performed. Since voltage, temperature management, and current management of the battery cells V1, V2, and V3 are performed on the battery pack 450 side, the battery pack 450 can be protected even when used for an electric appliance that does not have such a function. Since the voltages of the battery cells V1, V2, and V3 are individually monitored, highly accurate voltage monitoring control is performed, and control is performed according to any of the battery cells V1, V2, and V3 having the lowest voltage. As a result, the life of the battery pack 450 can be extended. Since battery discharge protection is performed by the control microcomputer 454 mounted on the battery side, the set value can be set in accordance with the cell. For example, even when a battery cell with good performance or an inexpensive cell is used, the set value can be set according to the cell performance, so that the life can be extended.

In this embodiment, the control microcomputers 303 and 454 communicate with each other by setting the connection portions C and D to the Hi level or the Low level. However, the present invention is not limited to this, and another communication method may be performed. For example, the control microcomputers 303 and 454 may perform digital communication so that the battery cell voltage, temperature, energization current value, and the like are transmitted and received as digital data.

In addition, although the connection part C is configured to transmit and receive the state of the main switch, the connection part C may be omitted. In this case, the control microcomputer 454 may be configured to always output a low level signal from the connection portion D as long as the battery pack 450 can be activated. The connection unit D is configured to transmit a signal when in a discharge-permitted state, but may transmit a signal when in a discharge-inhibited state.

If the control microcomputer 303 determines that the battery pack 450 does not satisfy the start permission condition or satisfies the device stop condition, the control microcomputer 303 turns on the LED 5 to notify the user that the battery is in an undischargeable state. Good. Further, although not shown, if the abnormal temperature of the heat conversion unit is detected as in the configuration of FIG. 55 and it is detected that the electric appliance is in a discharge disabled state, the LED 5 may be blinked or the LED 6 may be turned on. Good.

If the control microcomputer 454 determines that the battery pack 450 does not satisfy the start permission condition or satisfies the device stop condition when the remaining capacity switch 455 is pressed, the remaining capacity display circuit 458 is set to the normal remaining capacity. A display different from the display pattern may be displayed. For example, by blinking the LED, it can be notified that the battery pack 450 is unusable.

The energization control switch 305 and the drive circuit 306 may be configured to be mounted on the battery pack 450 side in addition to the configuration mounted on the electric appliance 350 side. In that case, the control microcomputer 454 may be configured to control the drive circuit 306.

FIG. 60 shows a control state when the battery pack 400 is set in the charger 500 and charged. In FIG. 60, the remaining capacity switch 409 of the battery pack 400 is omitted. In the charger 500, an AC power source 501 such as commercial 100V is converted into a direct current by the input rectifier circuit 502, and this direct current is converted into a predetermined current value or voltage value by the SW power source circuit 503.
