Bright main process, therefore be described in detail later.
It addition, in control portion 32, in addition to processing at the control of discharge shown in Fig. 5, Fig. 6,
Also perform when discharging to electric tool, when battery 10 charges, monitor via current detecting electricity
The discharge current of resistance 24 detection, charging current, make electric discharge or charging stop when there is current anomaly
Current surveillance control process only etc., various control process.But the electric discharge control shown in Fig. 5, Fig. 6
Control process beyond system process is not that the control of the present invention processes, therefore the description thereof will be omitted.
It follows that set of cells 2 possesses: for inputting to the 1st communication terminal 8 from electric tool
The 1st input control portion 42 and the 2nd to control portion 32 is inputted with the signal of the 2nd communication terminal 9
Input control portion 44；For the output signal that will export from control portion 32 via the 1st communication terminal
8 and the 2nd communication terminal 9 exports the 1st output control part 46 and the 2nd to electric tool output
Output control part 48.
Here, the 1st communication terminal 8 be arranged on right with the communication terminal 58 of the 1st instrument 50 side
The position answered, as it is shown on figure 3, be installed in the 1st instrument 50, power supply terminal in set of cells 2
4,6 when being connected with the power supply terminal 54,56 of the 1st instrument 50, the 1st communication terminal 8 and the 1st
The communication terminal 58 of instrument 50 connects.
It addition, the 2nd communication terminal 9 be arranged at right with the communication terminal 79 of the 2nd instrument 70 side
The position answered, as shown in Figure 4, is installed in the 2nd instrument 70, power supply terminal in set of cells 2
4,6 when being connected with the power supply terminal 74,76 of the 2nd instrument 70, the 2nd communication terminal 9 and the 2nd
The communication terminal 79 of instrument 70 connects.
It follows that as shown in Figure 3, Figure 4, the 1st instrument the 50 and the 2nd instrument 70 possesses respectively:
The triggering switch 62,82 of on/off operation is carried out by user；The power source of electric tool that is electricity
Machine 60,80；Switch element 64,84(are FET in the drawings) and control of discharge portion 66,86.
In the 1st instrument the 50 and the 2nd instrument 70, trigger switch 62,82, motor 60,80
And switch element 64,84 is arranged on the power supply terminal from side of the positive electrode the most in series
54,74 on the electrical path of the power supply terminal 56,76 of negative side.
And, control of discharge portion 66,86 is at the 1st instrument 50 or the 2nd himself being set
Instrument 70 is provided with set of cells 2, and when triggering switch 62 or 82 and being turned on, from
The battery 10 of set of cells 2 accepts power supply supply and carries out action.
Control of discharge portion 66,86 is configured to centered by microcomputer, and if from as above
State described battery 10 and accept power supply supply, then internal manostat generates microcomputer and drives
Supply voltage and start microcomputer.
So, control of discharge portion 66,86 by the action of microcomputer from communication terminal 58,
79 outputs represent the actuating signal of the high level of the meaning being in action, and by this meaning to battery
Group 2 notice.
So, if from the 1st instrument the 50 or the 2nd instrument 70 lateral set of cells 2 input action letter
Number, then utilize control of discharge described later to process from set of cells 2 via the 1st communication terminal 8 and the 2nd
Communication terminal 9 output allows battery 10 to carry out discharge (in other words motor 60,80 is driven)
Electric discharge allow signal.
Therefore, control of discharge portion 66,86 voltage level based on communication terminal 58,79 judges
The most it is transfused to electric discharge from set of cells 2 and allows signal, if being transfused to electric discharge to allow signal,
Then it is driven switch element 64,84 controlling, thus motor 60,80 is driven and controls
Make its rotary speed.
Additionally, in set of cells 2, the 1st output control part the 46 and the 2nd output control part 48 with
The common output mouth of control circuit 30 connects.
Therefore, not only lead to from the 1st communication terminal the 8 or the 2nd corresponding with each instrument 50,70
Letter terminal 9, also from another communication terminal, (in other words, the 2nd communication terminal the 9 or the 1st is led to
Letter terminal 8) output control part 32 electric discharge that export the 1st instrument the 50 or the 2nd instrument 70 is fair
Permitted signal.
But, make electric discharge allow signal to lead to from the 1st communication terminal the 8 or the 2nd in control portion 32
Letter terminal 9 is when the 1st instrument the 50 or the 2nd instrument 70 being provided with set of cells 2 exports, separately
One communication terminal (the 2nd communication terminal 9 or the 1st communication terminal 8) not with other instruments (
2 instrument the 70 or the 1st instruments 50) connect.
Therefore, even if never needing to output electric discharge to allow signal, another lead-out terminal the (the 2nd
Communication terminal the 9 or the 1st communication terminal 8) output electric discharge permission signal, also will not give and install
The action having the 1st instrument the 50 or the 2nd instrument 70 of set of cells 2 brings impact.
Illustrate it follows that the control of discharge performed in the control portion 32 of set of cells 2 is processed.
It is the process repeatedly performed in units of the stipulated time by control portion 32 that this control of discharge processes,
If starting as it is shown in figure 5, process, first represent step at S110(S) the most whether judge
It is in and carries out the electric discharge discharged to the 1st instrument the 50 or the 2nd instrument 70 from battery 10.
Then, if being judged as being not currently in electric discharge at S111, then S120 is moved to.
S120 is taken into by battery voltage detection portion 26 and battery via A/D converter section 36
Magnitude of voltage that cell voltage test section 34 detects, detect at battery cell temperature test section 22
Battery cell temperature, and judge whether these each values can carry out power supply supply to electric tool
In the normal range of (electric discharge).
If being judged as in S120, above-mentioned each value is within normal range, it is possible to allow to electric tool
Discharge, then move to S130, judge whether actuating signal is input to the 1st communication terminal 8
Or the 2nd communication terminal 9.
In other words, as it has been described above, in the 1st instrument the 50 or the 2nd instrument 70, if installing electricity
Pond group 2, triggers switch 62 or 82 and is turned on, then actuating signal is from the 1st instrument 50
Or the 2nd instrument 70 is input to the 1st communication terminal the 8 or the 2nd communication terminal 9.
Therefore, by judging whether actuating signal is input to the 1st communication terminal 8 in S130
Or the 2nd communication terminal 9, judges to be installed in the 1st instrument 50 or the 2nd in set of cells 2
Under the state of instrument 70, the triggering switch 62,82 of the 1st instrument the 50 or the 2nd instrument 70 is
No by operated by user.
If it addition, being judged as that in S130 actuating signal is input to the 1st communication terminal 8 and the 2nd
Communication terminal 9 or be judged as that in S120 above-mentioned magnitude of voltage or battery cell temperature be not just
In the range of Chang, the most temporarily terminate this control of discharge and process.
On the other hand, if being judged as in S130, actuating signal is input to the 1st communication terminal 8
Or the 2nd communication terminal 9, then move to S140, whether judge to be transfused to the terminal of actuating signal
It it is the 2nd communication terminal 9.
Then, in S140, it is judged as that the terminal being transfused to actuating signal is not the 2nd communication terminal 9
In the case of, it is possible to it is judged as that actuating signal is inputted to the 1st communication terminal 8 from the 1st instrument 50,
Therefore in ensuing S150, the 1st instrument 50 output electric discharge is allowed signal, and temporarily terminate
This control of discharge processes.
Additionally, in S150, by via the 1st output control part 46 by the 1st communication terminal 8
Switch to the connection status being connected with power line from open state, make the electric discharge of high level allow letter
Number it is output from the 1st communication terminal 8.
This is owing to being configured to, and the control of discharge portion 66 of the 1st instrument 50 is based on communication terminal 58
Voltage level detect the electric discharge from set of cells 2 and allow the input of signal, and start motor 60
Driving (electric discharge in other words carried out to motor 60 from battery 10).
In other words, if by the process of S150, the communication terminal 58 of the 1st instrument 50 is transfused to
Electric discharge allows signal, then electric current will not flow to set of cells 2, communication terminal from control of discharge portion 66
58 are retained as high level.
Therefore, the control of discharge portion 66 of the 1st instrument 50 can be based on the voltage of communication terminal 58
Level detects electric discharge and allows the signal input from set of cells 2, and the driving starting motor 60 (is changed
The electric discharge carried out to motor 60 from battery 10 of speech).
It addition, by the 1st toolmarking is set to ON state in S150, by the 1st
The situation that instrument 50 is in action is stored in RAM or depositor etc..
It follows that be judged as that in S140 the terminal being transfused to actuating signal is the 2nd communication terminal 9
In the case of, in other words, the electric tool being provided with set of cells 2 is the situation of the 2nd instrument 70
Under, move to S160, judge whether cell voltage is allowing to judge voltage than the electric discharge in S120
More than high threshold voltage.
This is because, the 2nd instrument 70 for example, factory's use, it is than the 1st general instrument 50
Require higher moment.
In other words, in the present embodiment, moment is required as corresponding to this, to the 2nd instrument 70
Carrying out discharging condition during power supply supply, (in other words, battery 10 is surplus to set cell voltage
Covolume amount) lower limit be that ratio judges voltage big threshold value when judging in S120 that electric discharge allows
Above.
Therefore, in S160 by judge cell voltage be whether more than threshold voltage judge to
Whether the discharging condition that the 2nd instrument 70 carries out discharging is set up.
If it addition, being judged to cell voltage deficiency threshold voltage in S160, to the 2nd instrument 70
The discharging condition carrying out discharging is false, and the most temporarily terminates this control of discharge and processes.
If it addition, be judged as that in S160 cell voltage is more than threshold voltage, then moving to S170
The 2nd instrument 70 output electric discharge is allowed signal, and temporarily terminate the process of this control of discharge.
Additionally, by defeated to the 2nd communication terminal 9 via the 2nd output control part 48 in S170
Go out with the pulse signal of specified period change make the electric discharge that is made up of pulse signal allow signal from
2nd communication terminal 9 exports.
This is owing to being configured to, and the control of discharge portion 86 of the 2nd instrument 70 is based on communication terminal 79
The cyclically-varying of current potential detect the electric discharge from set of cells 2 and allow the input of signal, and start
The driving (electric discharge in other words carried out to motor 80 from battery 10) of motor 80.
In other words, when by the process of S170, the communication terminal 79 of the 2nd instrument 70 is transfused to
When the electric discharge being made up of periodically variable pulse signal allows signal, the current potential of communication terminal 79
Generating period changes.
Therefore, the control of discharge portion 86 of the 2nd instrument 70 can be based on the current potential of communication terminal 79
Cyclically-varying detect the input being allowed signal from the electric discharge of set of cells 2, and start motor
The driving (electric discharge in other words carried out to motor 80 from battery 10) of 80.
It addition, by the 2nd toolmarking is set to ON state in S170, by the 2nd
The situation that instrument 70 is in action is stored in RAM or depositor etc..
If it follows that being judged as currently being in the 1st instrument the 50 or the 2nd work in S110
Tool 70 carries out in the electric discharge discharged, then move to S200 and perform electric discharge permission signal control process.
As shown in Figure 6, electric discharge allow signal control process in, first at S210, based on
The mark that S150, S170 are arranged, judges that the electric tool in present discharge is the 1st instrument 50
Or the 2nd instrument 70.
And, if currently utilizing the 1st instrument 50 and being in electric discharge, then move to S220 and sentence
Whether the disconnected discharge current from current detecting part 38 input is more than the stipulated time (such as 1s)
The stopping Cutoff current (such as 1A) of not enough regulation.
If having carried out negative judgment in S220 (in other words, stopping at either discharge current
More than Cutoff current or discharge current deficiency stops Cutoff current, but elapsed time of this state
Not up in the case of the stipulated time), the most directly terminate this electric discharge and allow signal control to process, make
The electric discharge carried out to the 1st instrument 50 continues.
On the other hand, if being judged as that in S220 discharge current is not enough more than the stipulated time and stopping
Cutoff current, then move to S230.
Then, the electric discharge carried out to the 1st instrument 50 from the 1st communication terminal 8 is made to permit in S230
The output being permitted signal (high level) stops the acknowledging time (such as 5ms) of regulation, this regulation
Acknowledging time is the time that will not bring impact to the driving of the motor 60 in the 1st instrument 50,
This output is interior during stopping, and reads the electricity of the 1st communication terminal 8 via the 1st input control portion 42
Voltage level.
It follows that judge from the 1st work according to the voltage level read in S230 in S240
The input of the actuating signal (high level) of tool 50 output stops (in other words, the 1st work the most
Whether the triggering switch 62 of tool 50 is off-state).
Additionally, the reason making electric discharge allow the output of signal to temporarily cease in S230 is,
Allow the output procedure of signal from the electric discharge of the 1st communication terminal 8, the electricity of the 1st communication terminal 8
Voltage level is high level, it is impossible to judge whether actuating signal is input to the 1st from the 1st instrument 50
