摘要： A device may include a battery module configured to power a load. The device may include a precharge relay switch electrically connected between the positive node of the battery module and the load and in series with a precharge resistor. The device may include a negative relay switch electrically connected between a negative node of the battery module and the load. The precharge relay switch and the negative relay switch are set to a closed state and the positive relay switch is set to an opened state when an electrical connection to the load is detected at a first time, and the precharge relay switch is set to an opened state and the positive relay switch is set to a closed state at a second time when a difference between a voltage across the load and a voltage of the battery module satisfies a threshold difference.

摘要： In a battery pack and an electrical device, one or more sensors are provided at a battery pack side, and sensor information acquired on a battery side is used to control an electrical device main body. Sensors that collect and output physical information arising due to external factors are provided at a battery pack, and a control part of the battery pack processes signals detected by the sensors and creates a control signal compatible with a mounted electrical device main body. The control part of the battery pack transmits, to the electrical device main body, a signal for controlling the electrical device main body via a communication terminal to enable a control part of the electrical device main body to perform optimal control using sensor information.

The acquisition unit acquires parameters including charge/discharge power, a charge/discharge capacity, and SOC of the storage battery system of a storage battery system. The deterioration prediction unit predicts deterioration of the storage battery system on the basis of the acquired parameters. The calculation unit performs calculation relating to deterioration by multiple patterns with respect to one or more of parameters including the charge/discharge power, a C rate indicating a charging/discharging speed, etc., on the basis of a digital model and the predicted deterioration. The calculation unit specifies a pattern whose life extension effect is relatively high. The display control unit causes a display device to display the one or more parameters of the specified pattern.

摘要： A system, method, and computer program product for utilizing an ultrasonic sensor compensating for the physical conditions of an internal battery compartment (e.g., temperature and/or humidity), to detect a hazardous battery condition, is provided. An example system includes a battery case defining an internal battery compartment and one or more battery cells contained in the internal battery compartment. The example system further includes an acoustic transmitter disposed within the internal battery compartment and configured to transmit an acoustic signal. In addition, the example system includes an acoustic receiver also disposed within the internal battery compartment and positioned to receive the transmitted acoustic signal. The example system monitors the time of flight of the acoustic signal and detects the hazardous battery condition of the one or more battery cells based on a change in the time of flight of the acoustic signal.
