Definitions

  • One aspect of the present invention is a power storage system used for an air vehicle, which is a power transfer circuit connected to a plurality of power storage devices and the plurality of power storage devices and transfers electric power between the plurality of power storage devices. And.
  • Each of the power storage devices 11, 12 and 13 is equipped with a BMU (Battery Management Unit) 31.
  • the BMU 31 measures the state of the plurality of power storage modules 32 included in the power storage device and controls the operation of the plurality of power storage modules 32.
  • the power storage system 1 includes a control device 5 that controls the power storage devices 11, 12, and 13.
  • the BMU 31 included in each of the power storage devices 11, 12 and 13 is connected to the control device 5.
  • the temperature acquisition unit 316 may acquire the temperature of each of the plurality of storage modules 32 or the temperature of each of the plurality of storage cells 33.
  • the communication unit 317 is connected to the control device 5.
  • the communication unit 317 communicates with the control device 5.
  • the calculation unit 311 causes the communication unit 317 to transmit information indicating the acquired voltage and current to the control device 5.
  • FIG. 7 is a flowchart showing a third example of the procedure of the process of transferring electric power between a plurality of power storage devices.
  • the voltage acquisition unit 314 acquires the voltage related to the power storage device 11, 12 or 13, and the communication unit 317 transmits information indicating the acquired voltage to the control device 5.
  • the control device 5 acquires the voltage related to each of the power storage devices 11, 12 and 13 by receiving the information indicating the voltage transmitted from the plurality of BMUs 31 in the communication unit 54 (S31).
  • the calculation unit 51 ends the process. If there is a power storage device with low soundness (S33: NO), the calculation unit 51 ends the process. If there is a power storage device with low soundness (S33: YES), the calculation unit 51 performs a process for transferring power from the power storage device with high soundness to the power storage device with low soundness (S34). In S34, the calculation unit 51 causes the power adjustment unit 55 to operate the power transfer circuit 4 in order to transfer the power.
  • the calculation unit 51 reduces the power supplied from the high-temperature power storage device to the load (S44).
  • the calculation unit 51 transmits a control signal for reducing the electric power from the communication unit 54 to the BMU 31 of the high-temperature power storage device.
  • the communication unit 317 receives the control signal, and the calculation unit 311 controls to reduce the power supplied from the power storage device according to the control signal. For example, power equivalent to the power transferred from the low temperature power storage device is reduced from the supplied power.
  • the electric power transferred from the low temperature power storage device is supplied to the load connected to the high temperature power storage device.
  • the power storage system 1 can also transfer power between a plurality of power storage devices connected to the load.
  • FIG. 9 is a block diagram showing a state in which electric power is transferred between a plurality of power storage devices 12 and 13 connected to a load.
  • the control device 5 operates the power transfer circuit 4 so as to transfer power from the power storage device 12 to the power storage device 13.
