  FIG. 3 is a block diagram showing the configuration of the storage battery pack in the present embodiment.

  The storage battery pack 20 includes a storage battery unit 201, a control unit 202, a communication terminal 203, a current detection unit 204, a holding unit 205, and a presentation unit 206.

  The storage battery unit 201 is a storage battery that charges or discharges electric power.

  The control unit 202 periodically acquires history information of the operation of the storage battery pack 20 and stores it in the holding unit 205. Specifically, the control unit 202 acquires the voltage output from the storage battery unit 201, the temperature of the storage battery unit 201, the current value detected by the current detection unit 204, and stores the acquired value in the holding unit 205. Further, the control unit 202 stores the current state and the past state (normal or abnormal) of the plurality of items of history information in the holding unit 205.

  The communication terminal 203 is a terminal for communicating with a predetermined device when the storage battery pack 20 is attached to the predetermined device.

  The current detection unit 204 is a current sensor that detects a current output from the storage battery unit 201.

  The presentation unit 206 is a user interface that presents the operating state of the storage battery pack 20.

  The holding unit 205 holds operation history information and inspection history information of the storage battery pack 20. The operation history information is information including a history such as the operating environment of the storage battery pack 20. An example of this information is shown in FIG.

  FIG. 4 is an explanatory diagram of the operation history information held by the storage battery pack according to the present embodiment. FIG. 4 shows an operation history information table T401 that summarizes operation history information.

  The operation history information includes, for example, entries including information on “operation date”, “voltage”, “temperature”, and “presence / absence of overcharge”.

  The “operation date” stores the date and time when the storage battery pack 20 was operating.

  “Voltage” stores the output voltage of the storage battery pack 20 on the operation day.

  “Temperature” stores the temperature of the storage battery pack 20 on the operation day.

  “Presence / absence of overcharge” stores a value indicating whether or not the storage battery pack 20 is overcharged on the operation day.

  In addition, the control unit 202 acquires operation history information at predetermined time intervals and stores the operation history information in the holding unit 205. When storing, the control unit 202 deletes the old stored operation history information that does not include an abnormal value so that the entries of the operation history information can be reduced to a predetermined number. It may be. By deleting those that do not include abnormal values, it is possible to save storage capacity while leaving entries that include abnormal values that serve as a basis for determining the state of the past storage battery pack 20.

  The holding unit 205 holds an RSOC (Real State Of Charge) of the storage battery unit 201. The RSOC is a physical quantity indicating the maximum capacity that can be charged in the storage battery unit 201. There is SOC (State Of Charge) as a similar physical quantity. The SOC indicates the maximum capacity that can be charged in the storage battery unit 201 at the start of use. On the other hand, the RSOC indicates the maximum capacity that can be charged in the storage battery unit 201 at the time of measurement, and generally decreases with time. In addition, when the storage battery unit 201 is overcharged or overdischarged, the storage battery unit 201 decreases in a larger range than the decrease with time. The RSOC is acquired every six months, for example, and the acquired RSOC is stored in the holding unit 205.

  FIG. 5 is an explanatory diagram of a method for calculating the remaining life of the storage battery pack in the present embodiment. The remaining life of the storage battery pack is one of the states of the storage battery pack 20 performed by the determination unit 102.

  The horizontal axis of FIG. 5 shows the elapsed time from the start of use of the storage battery pack 20. On the vertical axis, RSOC is shown. Here, RSOC is shown as a ratio of 100 at the start of use.

  The solid line in FIG. 5 shows the change in RSOC of the storage battery pack 20 when used in a standard usage method. Since the RSOC of the storage battery pack 20 is considered to decrease at a constant rate with the passage of time when used in a standard usage method, the solid line is shown by a straight line. And the time when RSOC falls below 60% (in FIG. 5, when 10 years have passed since the start of use) is set to be the absolute life of the storage battery pack 20.

  The black dots in FIG. 5 indicate RSOC (actually measured values) measured by the storage battery pack 20. As described above, when the RSOC is acquired every six months, three actually measured values are obtained after one year from the start of use.

  A one-dot chain line in FIG. 5 is an example of an estimated transition of the RSOC of the storage battery pack 20. The estimated transition is obtained as an approximate straight line of the actually measured value of RSOC obtained as described above on the condition that the RSOC at the start of use is 100%. Here, the estimated transition is a transition of the RSOC estimated according to the actual usage status of the storage battery pack 20. The point in time when this straight line falls below 60% is the estimated life. In the example of FIG. 5, the estimated life is shown as 7 years.

  The determination unit 102 calculates the remaining life of the storage battery pack using (Equation 1) using the above value.

    (Life expectancy) = (absolute life)-((elapsed time) + (shortening period)) (Formula 1)

  Here, the shortening period is expressed by (Formula 2).

    (Shortening period) = (absolute life)-(estimated life) (Equation 2)

  The absolute life is a usable period to be completed when the storage battery pack 20 is used in a standard usage method. Further, the elapsed time is an elapsed time from the start of use of the storage battery pack 20. The shortened period indicates a period shortened depending on the use state in the absolute life, and becomes zero when used in a standard usage method. On the other hand, the shortening period becomes a value larger than zero when it is determined that the life of the storage battery pack 20 after the start of use is shortened as compared with the case where the storage battery pack 20 is used in a standard usage method.

  FIG. 6 is a flowchart of a storage battery pack inspection process performed by the storage battery inspection apparatus according to the present embodiment.

  In step S601, the storage battery inspection device 10 is attached to the storage battery pack 20 by a maintenance person or the like. Specifically, the connection unit 101 of the storage battery inspection device 10 is attached to the communication terminal 203 of the storage battery pack 20. Thereby, the storage battery inspection device 10 can communicate with the storage battery pack 20. When the storage battery pack 20 is attached to a predetermined device, the storage battery inspection device 10 is also removed from the predetermined device before being attached in step S601.

  In step S602, the power supply of the storage battery inspection apparatus 10 is turned on.

  Note that the order of steps S601 and S602 may be either.

  If the order is as described above, the storage battery pack 20 is already attached at the time when the storage battery inspection device 10 is turned on. Therefore, the storage battery inspection device 10 immediately performs the inspection process of the storage battery pack 20 after the power is turned on. There is a merit that it can be done. On the other hand, if it is limited only to this order, when the plurality of storage battery packs 20 are to be inspected, each time the storage battery pack 20 to be inspected is replaced, it is necessary to turn off and on the power supply of the storage battery inspection apparatus 10, which is complicated. There is a demerit that there is.

  On the other hand, if the storage battery inspection device 10 is turned on (step S602) and attached to the storage battery pack 20 (step S601), electrical noise at the time of attachment enters the storage battery inspection device 10 and the storage battery pack 20 and causes a failure. There is a disadvantage of obtaining. On the other hand, when a plurality of storage battery packs 20 are to be inspected, there is an advantage that the power supply OFF and ON operations of the storage battery inspection apparatus 10 are not required to replace the inspection target storage battery pack 20 and the convenience is improved. In this case, the determination unit 102 may acquire history information when the connection unit 101 is attached to the communication terminal 203.

  In step S <b> 602, the determination unit 102 acquires the history information held in the holding unit 205 of the storage battery pack 20 through the connection unit 101.

  In step S603, the determination unit 102 determines the state of the storage battery pack 20 by comparing the history information acquired in step S602 with the state table.

  In step S604, the presentation unit 103 presents the determination result in step S603. Specifically, the presentation unit 103 sequentially presents information about each of the health status of the storage battery pack 20, life expectancy, overall reviews, and details of the determination result. In order to switch the information to be presented as described above, the button 1042 of the input unit 104 may be used. That is, the presentation unit 103 may sequentially switch information to be presented each time the button 1042 is operated. Switching of information to be presented will be described with reference to FIG.

  FIG. 7 is an explanatory diagram of the transition of the display image of the storage battery inspection device in the present embodiment.

  (A) of FIG. 7 is an image displayed by the presentation unit 103 after the power of the storage battery inspection device 10 is turned on. The image is an image indicating that the storage battery pack 20 can be inspected. When the button 1042 is operated while the presentation unit 103 is displaying the image (a), the presentation unit 103 switches the display to the image of (b).

  FIG. 7B is an image that displays the health state of the storage battery pack 20. In the image of FIG. 7B, characters that clearly indicate the health condition and history information regarding the operation of the storage battery are displayed. When the button 1042 is operated while the presentation unit 103 is displaying the image (b), the presentation unit 103 switches the display to the image of (c).

  FIG. 7C is an image that displays the remaining life of the storage battery pack 20. In the image of FIG. 7C, the life expectancy determined by the determination unit 102 and related information including the value used for calculating the life expectancy are displayed.
