摘要： In a battery abnormality prediction system, an acquisition unit acquires a current flowing through a battery and a temperature of the battery. A prediction unit predicts the occurrence of an abnormality in the battery, based on a relationship between the amount of the current flowing through the battery for a certain period of time and a rise in the temperature of the battery for the certain period of time. The prediction unit may compare the ratio of an integrated amount of current to the temperature rise for the certain period of time with a threshold determined based on data on the battery having caught fire and thereby predict a sign of fire to be caught by the battery.

摘要： In a power supply system (10) and a method for controlling the same, at least one battery from among a plurality of batteries (12a-12d) is designated as a charging-side battery, and the remaining batteries are designated as discharging-side batteries. Next, the difference in current between the current flowing from the discharging-side batteries and the current flowing into the charging-side battery is determined on the basis of currents (I1-I4) measured by a plurality of current measuring instruments (26a-26d). Next, the transformation rate (Tr) of a voltage transformer connected to the discharging-side batteries is determined on the basis of the determined difference in current.

摘要： There are provided a voltage detection circuit that measures a voltage of an assembled battery 20 in which energy storage devices 100 are connected in series, a current detection resistor that detects a current of the assembled battery 20, and a CPU 33 that calculates an electrical quantity of energization by continuous charge or continuous discharge of the assembled battery 20. The CPU 33 controls input or output of the assembled battery 20 during charge and discharge such that a ΔSOC, which is a value obtained by dividing the electrical quantity of energization by an available capacity of the assembled battery 20, does not exceed an upper limit ΔSOC.

摘要： Provided are a charge/discharge device, a charge/discharge control method, and a computer program that exhibit high responsiveness while following a prescribed sequence that corresponds to a charge/discharge procedure. This charge/discharge device has a connector to an onboard power line connected to a storage battery provided in a vehicle, the charge/discharge device controlling charging and discharging in the storage battery, wherein the charge/discharge device comprises: a communication unit that establishes a communication connection with an onboard control device that switches on and off a vehicle-side relay interposed in the onboard power line; a communication control unit that exchanges messages with the onboard control device through the communication unit on the basis of a prescribed sequence; and a connection-standby-state-maintaining unit that maintains a connection standby state in which the vehicle-side relay remains on while the storage battery is not being charged or discharged after the vehicle-side relay has been switched on on the basis of the prescribed sequence.
