PROBLEM TO BE SOLVED: To provide a charge/discharge system which can deal with a change in magnitude of the system by employing a master-slave system and independently controls a master unit or each slave unit.SOLUTION: The charge/discharge system includes a master substrate M and slave substrates S connected thereto. Power generators 1M, 1S are connected to the master substrate M and the slave substrates S, respectively, and the substrates are each connected to a secondary battery EDLC (electric double layer capacitor) for storing power from the power generators 1M, 1S. An LED illuminator and other load are connected to the substrates M, S, respectively. The substrates each include: a charge control section 2 for charging the power from the power generator connected to each substrate, into the secondary battery; and a discharge control section 3 for supplying power from the secondary battery to the load connected to each substrate. The master substrate M has a communication control section 4 for transmitting a common control signal to the respective substrates. A priority storage section 5 of the master substrate M stores the priorities of the respective slave substrates, and the slave substrates each perform charge/discharge control in accordance with the priority. |
