摘要:
An electricity storage device includes a plurality of cell batteries C1 to CM serially connected; and a management module including a balance circuit that can selectively cause electricity to be discharged from each of the plurality of cell batteries, and a controller. The controller includes a current-voltage acquiring unit that acquires a charging current and the respective voltages of the plurality of cell batteries and a balance control unit that, if a determination condition and an execution condition are satisfied, determines a lowest-voltage cell battery having a lowest voltage among the plurality of cell batteries and controls the balance circuit such that electricity is discharged from the plurality of cell batteries other than the lowest-voltage cell battery for time periods in accordance with differences between the lowest voltage and the respective voltages of the cell batteries when the determination condition and the execution condition are satisfied.

An equipment management method comprises a step A of predicting, at an equipment management apparatus, occurrence of a first abnormality which is an abnormality occurred in a fuel cell system and not predicted by the fuel cell system; and a step B of transmitting, at the equipment management apparatus, a message associated with a prediction for the occurrence of the first abnormality when the occurrence of the first abnormality is predicted.
摘要:
A power storage apparatus includes a power storage module, a temperature acquirer, a state-of-charge calculator, and a charge controller. The power storage module includes a plurality of batteries connected to each other. The temperature acquirer acquires a temperature of the power storage module. The state-of-charge calculator calculates a state of charge of the power storage module. The charge controller charges the power storage module with a current value that is set based on the acquired temperature and the calculated state of charge.

A PCS performs a control of increasing an output of a solar cell to exceed the suppression power threshold, when there is a period, where the output of the solar cell falls below a suppression power threshold, in an accumulation period included in a suppression period in which the output of the solar cell is suppressed.
摘要:
A power control apparatus comprises a conversion unit which is capable of collectively converting DC power output by each of the plurality of power supply apparatuses to AC; and a communication unit which communicates with an external equipment control apparatus in accordance with a predetermined communication protocol. The communication unit notifies the equipment control apparatus of an equipment class of the power control apparatus in addition to notifying the equipment control apparatus of an equipment class of each of the plurality of power supply apparatuses.
摘要:
A power supply apparatus is connectable to a common communication line together with at least one other apparatus. The power supply apparatus includes a communication interface and a controller. The communication interface is configured to transmit a signal indicating the presence of the power supply apparatus to a first apparatus connected to the power supply apparatus among the at least one other apparatus and to receive a signal indicating the presence of a second apparatus from the second apparatus connected to the power supply apparatus among the at least one other apparatus. The controller is configured to determine whether the power supply apparatus is connected to an end portion of the common communication line, based on whether the communication interface has received the signal indicating the presence of the second apparatus.
摘要:
A fuel cell system comprises an interface configured to receive a user operation toward the fuel cell system, and a controller configured to perform a predetermined process related to a reception stop of the user operation at least during a period from a start to an end of a stop operation of the fuel cell system.
摘要:
A fuel cell system comprises a controller configured to manage information related to a number of stop times of the fuel cell system, and an output unit configured to output the information related to the number of stop times.
摘要:
Remaining power generation capability of power generation apparatuses is estimated to a high degree of accuracy. A power conversion apparatus (1) includes input interfaces (11) that input generated power from each of multiple power generation apparatuses (10) of the same type and a controller (14) that performs MPPT control on a priority basis on at least one input interface among the input interfaces and acquires the remaining power generation capability of the power generation apparatuses (10) connected to the other input interfaces (11) by calculation using the generated current of the power generation apparatus (10) connected to the at least one input interface.
摘要:
A storage battery management device includes a control unit. The control unit obtains a current value of a current flowing through a storage battery, a temperature of the storage battery, and a charging rate of the storage battery during a target period. The control unit determines an operation mode of the storage battery during the target period on the basis of the current value and the charging rate. The control unit estimates a degree of degradation of the storage battery during the target period on the basis of the operation mode and the temperature.
