Abstract: A battery management system includes a control device and a storage. The storage stores at least one trained neural network. The trained neural network includes an input layer that accepts input data that represents a numeric value for each pixel in an image where a prescribed CCV waveform (a CCV charging waveform or a CCV discharging waveform) of a secondary battery is drawn in a region constituted of a predetermined number of pixels, and when input data is input to the input layer, the trained neural network outputs a full charge capacity of the secondary battery. The control device estimates the full charge capacity of a target battery by inputting input data obtained for the target battery into the input layer of the trained neural network.

Abstract: A control system for a hybrid vehicle includes an internal combustion engine, a rotary electric machine, a battery, a cooling fan configured to cool the battery, and a controller. The controller is configured to determine an operation of the cooling fan based on charged-discharged electric power of the battery and presence or absence of a charging request that is based on an intention of a user. The controller is configured to control the operation of the cooling fan such that the battery is cooled more in a case where the charging request is present than in a case where the charging request is absent with the same charged-discharged electric power.

Abstract: A battery string is configured such that a plurality of battery circuit modules can be connected in series. A middle point between a first capacitor and a second capacitor provided on a detection line connecting a positive electrode output line and a negative electrode output line of the battery string to each other is grounded by a ground line through a limiting resistor. During operation of the battery string, an electric leakage detection unit sets a battery circuit module in a pass-through state, and detects electric leakage in the battery string based on a differential voltage that is a difference between a first voltage being the voltage of the first capacitor and a second voltage being the voltage of the second capacitor.

Abstract: An electric power supply system includes an alternating current electric power supply circuit that converts direct current electric power of a first direct current sweep unit including a battery string into alternating current electric power using a first inverter and outputs it, and an alternating current sweep unit that includes a U-phase battery string, a V-phase battery string, and a W-phase battery string that are Y-connected. Output densities of batteries of the battery string are higher than output densities of batteries of the alternating current sweep unit. Alternating current electric power is output from the alternating current sweep unit and the alternating current electric power supply circuit, and after a predetermined period elapses, the output of the alternating current electric power from the alternating current electric power supply circuit is stopped.

Abstract: A power supply system 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.
