    摘要: The present teaching provides a technique for detecting a failure in a switching device early in a power supply system including a plurality of sweep modules. A power supply system 1 disclosed here is connected to an electric power system through a distribution device. The power supply system includes a plurality of strings connected to the distribution device and a failure detector. The failure detector of the power supply system is configured to perform a first process of connecting at least one battery module to a main line to set a voltage detected by a string voltage detector at a voltage higher than a predetermined voltage in a state where a switch disconnects the distribution device and the main line, a second process of sending a disconnecting signal for disconnecting all the sweep modules from the main line, and a third process of determining whether the voltage detected by the string voltage detector is lower than the predetermined determination voltage or not after the second process.

    摘要: A power supply system includes a controller (104), and a plurality of battery modules (102). The battery modules (102) are connected in series, according to a gate drive signal from the controller (104), to provide series connection, and each of the battery modules (102) has a disconnecting device (22) configured to force the battery module to be disconnected from the series connection. The controller (104) is configured to estimate the internal resistance of the battery module disconnected from the series connection by the disconnecting device (22), from a module voltage of the battery module before the battery module is disconnected from the series connection, a module voltage immediately after the battery module is disconnected, and a module current delivered from the battery module.

    摘要: A power source system (5) includes a direct current power source (10), a direct current power source (20), and a power converter (50) having a plurality of switching elements (S1-S4) and reactors (L1, L2). The power converter (50) performs a direct current voltage conversion between the direct current power sources (10, 20) and a power source line (PL) in parallel by controlling the switching elements (S1-S4). Each of the switching elements (S1-S4) is disposed to be included in both a power conversion path formed between the direct current power source (10) and the power source line (PL), and a power conversion path formed between the direct current power source (20) and the power source line (PL). A phase difference ( Æ ) between a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (10), and a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (20) is controlled according to the operation condition of the power converter (50).
