Here, it is assumed that the power consumer has a contract based on a discounted electricity rate system in the late-night time period that is introduced by many electric utilities. In addition, when a surplus power is generated, such as when the power consumer generates self-generated electricity using natural energy (sunlight, solar heat, wind power, etc.) and generates more power than the self-consumed portion, the surplus power (− carry out the sale of electricity to sell the P s) to the power company.

First, the storage battery control means 30 determines whether or not the current time is an electricity rate discount time zone based on the date and time indicated by the clock function unit 32 (S202). If the current time is the electricity rate discount time zone (S202: YES), the storage battery control means 30 determines the state of charge of the storage battery 10 (S204). As a result, if the battery 10 is fully charged state (S204: NO), the storage battery control unit 30 is to be charged at the charging amount P B to the battery 10, the switchboard control means 46 power consumption of electrical equipment 53 P L and determining whether the sum of the charge amount P B of the battery 10 is above the power generation amount P G of private power generation apparatus 52 (S206). If the sum of the charge amount P B of the power consumption P L and the battery 10 of the electric device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S206: YES), the storage battery control unit 30 the battery 10 is fully charged state The distribution panel control means 46 purchases the insufficient power amount P s = (power consumption amount P L + charge amount P B −power generation amount P G ) from the commercial power source 51 (S208). On the other hand, if the sum of the charge amount P B of the power consumption P L and the battery 10 of the electric device 53 is below a power generation amount P G of private power generation apparatus 52 (S206: NO), the storage battery control unit 30 the battery 10 is fully charged The distribution panel control means 46 sells the surplus power amount (−P s ) = (power generation amount P G −power consumption amount P L −charge amount P B ) to the commercial power source 51 (S210).

When the storage battery 10 is in a fully charged state at the time of S204 (S204: YES), or when the storage battery 10 is in a fully charged state in S208 or S210, the switchboard control means 46 is turned on until the discount time period ends. power consumption P L of the device 53 determines whether exceeds the power generation amount P G of private power generation apparatus 52 (S212). If the power consumption P L of the electrical device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S212: YES), the storage battery control unit 30 is on standby without charge was also discharged also the accumulator 10, the switchboard control unit 46 Purchases the power amount P s = (power consumption amount P L −power generation amount P G ) from the commercial power source 51 (S214). On the other hand, if the power consumption P L of the electrical device 53 is below a power generation amount P G of private power generation apparatus 52 (S212: NO), the storage battery control unit 30 is on standby without charge was also discharged also the battery 10, switchboard control The means 46 sells the surplus power amount (−P s ) = (power generation amount P G −power consumption amount P L ) to the commercial power source 51 (S216).

If the current time is not the electricity rate discount time zone (S202: NO), the storage battery control means 30 determines the time until the scheduled use time of the electric vehicle input by the input reception means 34 (S218). If the time until the scheduled use time of the electric vehicle is less than a predetermined time (the time required to make the storage battery 10 fully charged, for example, 4 hours) (S218: YES), the storage battery control means 30 determines the charge state of the storage battery 10 (S220). Then, if the fully charged battery 10 (S220: NO), the storage battery control unit 30 is to be charged at the charging amount P B to the battery 10, the switchboard control means 46 power consumption of electrical equipment 53 P L and accumulators the sum of the charge amount P B of 10 determines whether is greater than the power generation amount P G of private power generation apparatus 52 (S222). If the sum of the charge amount P B of the power consumption P L and the battery 10 of the electric device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S222: YES), the storage battery control unit 30 the battery 10 is fully charged state The switchboard control means 46 purchases the insufficient power amount P s = (power consumption amount P L + charge amount P B −power generation amount P G ) from the commercial power source 51 (S224). On the other hand, if the sum of the charge amount P B of the power consumption P L and the battery 10 of the electric device 53 is below a power generation amount P G of private power generation apparatus 52 (S222: NO), the storage battery control unit 30 the battery 10 is fully charged The distribution panel control means 46 sells the surplus power (−P s ) = (power generation amount P G −power consumption P L −charge amount P B ) to the commercial power source 51 (S226).

If the battery 10 is fully charged at the time of S220 (S220: YES) if the battery 10 becomes fully charged state or in S224 or S226, the switchboard control unit 46 electric power consumption P L of the electrical device 53 determining whether exceeds the power generation amount P G of private power generation apparatus 52 (S228). If the power consumption P L of the electrical device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S228: YES), the storage battery control unit 30 is on standby without charge was also discharged also the accumulator 10, the switchboard control unit 46 Purchases the power amount P s = (power consumption amount P L −power generation amount P G ) from the commercial power source 51 (S230). On the other hand, if the power consumption P L of the electrical device 53 is below a power generation amount P G of private power generation apparatus 52 (S228: NO), the storage battery control means 30 while waiting without charge was also discharged also the accumulator 10, the switchboard The control means 46 sells the surplus power amount (−P s ) = (power generation amount P G −power consumption amount P L ) to the commercial power source 51 (S232).

If time to use scheduled time of the electric vehicle is not less than the predetermined time (S218: NO), whether the storage battery control means 30 power generation amount P G of private power generation device 52 exceeds the power consumption P L of the electrical device 53 It is determined whether or not (S234). If power generation amount P G of private power generation system 52 exceeds the power consumption P L of the electrical device 53 (S234: YES), further battery control unit 30 determines the state of charge of the battery 10 (S236). If the storage battery 10 is in a fully charged state (S236: YES), the storage battery control means 30 does not charge or discharge the storage battery 10, and the switchboard control means 46 determines the surplus power (−P s ) = (power generation). The amount P G -the power consumption amount P L ) is sold to the commercial power source 51 (S238). On the other hand, if the storage battery 10 is not in a fully charged state (S236: NO), the storage battery control means 30 charges the storage battery 10 until it is in a fully charged state, while the switchboard control means 46 has a surplus power (−P s ) = (Power generation amount P G -Power consumption amount P L -Charge amount P B ) is sold to the commercial power source 51 (S240).

On the other hand, when the power generation amount P G of private power generation apparatus 52 is below the power consumption P L of the electrical device 53 (S234: NO), the amount of power storage battery control unit 30 is insufficient in battery 10 P s = (power The consumption amount P L -the power generation amount P G ) is discharged (S242).

  By repeating the above processing flow, the storage battery control means 30 and the switchboard control means 46 perform necessary controls such as charging / discharging of the storage battery 10 and buying and selling of electricity with the commercial power source 51 at each time point.
