Japanese Unexamined Patent Publication No. 2018-169393 discloses a configuration for estimating deterioration of a power storage element (decrease in the capacity of the power storage element) based on SOC data. Using the technique described in JP-A-2018-169383, the SOH at each of a plurality of time points carved at predetermined intervals, for example, at intervals of 1 second, is calculated, and the life, for example, SOH is reduced to 70%.

The operation unit 51 receives inputs of the conversion efficiency of the power conditioner 61, the conversion efficiency of the transformer 60, and the transmission efficiency of the power line W on the charge / discharge reception screen. The charge amount Pc1 and the discharge amount Pc2 related to the power storage device 1 are calculated based on the two conversion efficiencies and the transmission efficiencies input through the operation unit 51. The operation unit 51 also functions as a first efficiency reception unit, a second efficiency reception unit, and a third efficiency reception unit.

If the user selects the second model or third model, that is, if the power storage system 6 does not contain trans 60, the user may input a 1 as the conversion efficiency of the transformer 60. As a result, in the equations (1) and (2), 1 is substituted for the conversion efficiency Et, and the equations for calculating the charge amount Pc1 and the discharge amount Pc2 are converted into the equations (3) and (4).
When the first model is selected, the transmission efficiency of the power line W input by the user through the operation unit 51 is the transmission efficiency of the two power lines W and W as a whole.

Whether or not the operation unit 51 has received the pattern file F generation instruction when the control unit 53 determines that the operation unit 51 has not received the pattern data generation instruction (S12: NO) or after executing step S14. Is determined (step S15).
When the pattern data is not generated, the operation unit 51 does not accept the generation instruction of the pattern file F.

When the control unit 53 determines that the operation unit 51 has received the generation instruction of the pattern file F (S15: YES), the control unit 53 generates the pattern file F including the latest pattern data generated in step S13 (step S16). A control section 53 to the next, writing a pattern file F generated in step S16 in the storage unit 52 (step S17). When the control unit 53 determines that the operation unit 51 has not received the generation instruction of the pattern file F (S15: NO), or after executing step S17, the operation unit 51 describes the contents of the charge / discharge reception screen. It determines whether it has received a reset instruction (step S18).

When the control unit 53 determines that the operation unit 51 has received the reset instruction (S18: YES), the control unit 53 resets the contents of the charge / discharge reception screen (step S19). As a result, for example, the content selected or input on the charge / discharge reception screen is changed as follows. The operation of the set period, the repetition of the operation of the list, and the operation of the undetermined period are changed to the preset initial contents. The input contents of the list are lost. The conversion efficiency of the power conditioner 61, the conversion efficiency of the transformer 60, and the transmission efficiency of the power line W are changed to preset initial values, for example, 1.

The control unit 53 determines whether or not the operation unit 51 has received the end instruction of the pattern generation process when it is determined that the operation unit 51 has not received the reset instruction (S18: NO) or after executing step S19. Judgment (step S20). When the control unit 53 determines that the operation unit 51 has not received the end instruction of the pattern generation process (S20: NO), the control unit 53 executes step S12 and waits until the operation unit 51 receives the end instruction. When the control unit 53 determines that the operation unit 51 has received the end instruction of the pattern generation process (S20: YES), the control unit 53 ends the pattern generation process.
