Numerical value (starting voltage to the time for measuring end voltage since measurement) is recorded in record portion (such as the non-volatile memories of Fig. 3
Device C7) in.
Then, change events extraction unit 24 is found out by utilizing the calculating of recorded EDLC electric current and EDLC voltage
The electrostatic capacitance (step S11) of EDLC 14.In addition, being said for the specific example for finding out electrostatic capacitance by calculating below
It is bright.
Later, it is preset to judge whether the calculated electrostatic capacitance of change events extraction unit 24 is lower than for comparing section 25
Electrostatic capacitance decision content (step S12).Here decision content is used to determine the deterioration of EDLC 14, and comparing section 25 is for not up to
It is judged as that EDLC 14 is deteriorated when the capacity of decision content, electrostatic capacitance is reduced.
In the case that the electrostatic capacitance calculated in step s 12 is not below decision content (NO of step S12), output section 26
It is judged as that EDLC 14 is not completely deteriorated.At this point, the judgement information of no deterioration can be output to elevator control gear etc. by output section 26.
In addition, when the electrostatic capacitance calculated in being judged as step S12 is lower than decision content (YES of step S12), output
The judgement information for indicating that EDLC 14 is deteriorated is output in elevator control gear etc. (step S13) by portion 26.In addition, in electric power storage member
The deterioration of record EDLC 14 in record portion (such as non-volatile memory device C7 of Fig. 3) in part control unit 20.
In addition, the output of judgement result in step s 13 can be used the content for the measurement result for being based only upon this come into
Row determines, the temporal process of deterioration state can also be judged for example, by multiple measurement and exports sentencing for prediction future
Determine result.
In addition, the control signal that the judgement processing in step S1, step S5, step S8 is exported using elevator control gear
It is executed by moment configuration part 23.
Then, it is illustrated for the processing for seeking the electrostatic capacitance of EDLC 14 in step S11 by operation.
Fig. 5 is an example for indicating the time change of EDLC electric current and EDLC voltage when carrying out the charging to EDLC 14
The waveform diagram of son.In Fig. 5, EDLC electric current shows the value being negative, and EDLC voltage shows the value being positive.
In the Fig. 5, voltage V1 is at the time of reaching measurement to start voltage, and voltage V2 is to reach measurement end voltage
Moment.It is the charging time T of EDLC 14 during from voltage V1 to voltage V2.In charging time T, EDLC voltage is substantially
Linearly increase.The voltage change line Va after straight line is approximate is illustrated in Fig. 5.
In addition, the EDLC electric current of charging time T is reduced generally in straight line with the increase of EDLC voltage.EDLC electric current
I1 is the current value under measurement beginning voltage V1, and EDLC electric current I2 is the current value measured under end voltage V2.
In addition, D1 and becoming D2 at the time of value V2 at the time of becoming value V1 for EDLC voltage, can read in respectively once
Voltage value or current value, can also be to carry out the measured value that measures and records of multiple voltage value and current value in the short time
Average value.In Fig. 5, voltage V1, V2 is indicated with circle with surrounding and electric current I1, I2 are means to take being averaged within the scope of this
Value.
According to voltage V1, the V2 and electric current I1, I2 obtained in this way, by by the following Expression 1, formula 2, formula 3 operation come based on
Calculate the electrostatic capacitance C of EDLC 14.
[formula 1]
Q=C × V
[formula 2]
Q=(I1+I2) × T/2
[formula 3]
V=V2-V1
In these formulas, Q is the charging charge of EDLC 14, and C is the electrostatic capacitance of EDLC 14, and T is timer count
Value.By will seek the formula 2 of charging charge Q from electric current and charging time and seek the 3 substitution formula 1 of formula of voltage difference, can find out
The electrostatic capacitance of EDLC 14.
In this way, electric current, voltage and the charging time measured when can be according to charging finds out correct EDLC
Whether 14 electrostatic capacitance, the EDLC 14 that can correctly judge deteriorate.
The electric power of charging is obtained by using power transmission coil and the non-contact power of power receiving coil, is connect using non-
Touch the power transmission coil in the case where powering, when usually powering positional relationships and on-fixed, the Wu Fa such as at a distance from power receiving coil
Voltage V1, V2 and electric current I1, I2 are sought under conditions of fixation.Therefore, generally passing through non-contact power supplying charging current
Circuit in, even if carrying out the operation using above-mentioned formula 1, formula 2, formula 3, also can not correctly find out the electrostatic capacitance of EDLC 14
C。
In this regard, in the case where the lift appliance of present embodiment example, be configured with the carriage 6 of power receiving coil 13 due to
The same position lifting in hoistway 30 is gone up and down, the positional relationships such as the distance between power transmission coil 11 and power receiving coil 13 are solid always
It is fixed, it is charged with fixing electric power.Therefore, example carries out even if being the charging based on non-contact power according to the present embodiment
The electrostatic capacitance C that EDLC 14 can be correctly found out using the operation of formula 1, formula 2, formula 3, can speculate that EDLC's 14 is correct
Deterioration state.
In the prior art in the case where similar present embodiment example is by non-contact power supplying charging current, it is
The deterioration state of the correct EDLC 14 of diagnosis, needs to monitor the charge volume of EDLC 14 always, carries out at integral to charge volume
Reason, is judged according to the behaviour in service of EDLC 14.In contrast, in the case where present embodiment example, even if only to exist
Pass through the structure of non-contact power supplying charging current in short time, it also can be by comparing simple structure, free from errors
Correctly carry out the deterioration diagnosis of EDLC 14.
[deterioration of 5. charge storage elements diagnoses example (example 2)]
Then, illustrate other examples (example 2) of the deterioration diagnostic process of charge storage element.In this example embodiment, according to EDLC
Time needed for voltage change when 14 charging diagnoses the deterioration of EDLC 14.
Fig. 6 is the example (example 2) of the diagnostic process of the deterioration for the EDLC 14 for indicating that charge storage element control unit 20 carries out
Flow chart.In the flow chart of the Fig. 6, for the flow chart phase with the Fig. 4 illustrated in the diagnostic process of example 1 described above
Same processing or judgement, is accompanied by same steps mark and omits repeated explanation.
In the fig. 6 flow diagram, when EDLC voltage reaches measurement beginning voltage in step s 6 (YES of step S6), turn
Step S14 is moved on to, charge storage element control unit 20 resets the count value of diagnosis timer, starts the timing since reset value
The counting of device.After the counting starts, it is transferred to the judgement of the mobile beginning of the carriage 6 of step S8.
In addition, in the flow chart of Fig. 6, when EDLC voltage reaches measurement end voltage in step s 9 (step S9's
YES), it is transferred to step S15, change events extraction unit 24 stops the counting of timer and obtains count value, records the acquisition
Count value.After the record of the count value, charging time and preset charging time that comparing section 25 indicates count value
Decision content compare (step S16).
Here, in the case where the charging time that count value indicates is on the decision content in preset charging time
(NO of step S16), output section 26 are judged as that EDLC 14 is not completely deteriorated.
In addition, being judged as when the charging time is lower than decision content (YES of step S16) in step s 16, it is transferred to step
The expression EDLC 14 judgement information deteriorated is output to elevator control gear etc. and records the bad of EDLC 14 by S13, output section 26
Change state.
Then, judge that the example of the deterioration of EDLC 14 is based on actual characteristic in processing represented by the flow chart to Fig. 6
It is illustrated.

The waveform diagram of son.It is identical as characteristic Va shown in fig. 5 with the variation characteristic Va that solid line indicates in Fig. 7.Also, with dotted line table
Characteristic when the variation characteristic Vb of the voltage shown is the deterioration of EDLC 14.
As shown in fig. 7, under the original state for enabling EDLC 14 not completely deteriorated since measurement start voltage V1 to measure end voltage
The charging time (during charging) of V2 be period Tx when, EDLC 14 deterioration after in the state of, since measurement voltage V1 to
The charging time Ty of measurement end voltage V2 shortens.The shortening of charging time Ty is proportional to the deterioration state of EDLC 14.
The short time in the charging time (charging time) is because electrostatic capacitance (capacity C of formula 1) is with the deterioration of EDLC 14
And it reduces.
Therefore, by the way that charging time Ty compares with the decision content as preset threshold value, charge storage element control
Portion 20 can speculate the degradation of EDLC 14.
In the case where deteriorating diagnostic process shown in the flow chart of the Fig. 6, diagnosis is deteriorated shown in the process with Fig. 4
Processing can carry out correctly deterioration diagnosis similarly with fairly simple structure.Further, shown in the flow chart of Fig. 6
