摘要： A driver controls a switch inserted in a current path between a secondary battery and an inverter that drives a motor. A first abnormality detector instructs the driver to turn off the switch when an abnormality of the secondary battery is detected. A second abnormality detector is disposed in parallel with the first abnormality detector, and instructs the driver to turn off the switch when the abnormality of the secondary battery is detected. The first abnormality detector suspends an instruction to turn off the switch to the driver, even when the abnormality of the secondary battery is detected, in cases where an ECU instructs discharge-stop prohibition of the secondary battery. The second abnormality detector instructs the driver to turn off the switch after a lapse of a certain time from when the abnormality of the secondary battery is detected, regardless of an instruction from the ECU.

摘要： The server acquires first data concerning a load applied to a body of an electric mobile apparatus, acquires second data concerning the performance of a storage battery mounted on the mobile apparatus, calculates a remaining lifetime of the body on the basis of the first data, calculates a remaining lifetime of the battery on the basis of the second data, compares the remaining lifetime of the body with the remaining lifetime of the storage battery, and instructs at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus when the remaining lifetime of the body is shorter than the remaining lifetime of the storage battery.

摘要： A motor driving circuit has a supply line connected to a DC power source, an inverter whose input side is connected to the supply line and whose output side is connected to a motor, a power switch inserted in the supply line for switching the supply line between conducting and cut-off states, a voltage detector for detecting a voltage between the direct-current power source and the power switch, and an insulation resistance detector for first detecting, based on a result of detection by the voltage detector with the power switch in the cut-off state, an insulation resistance on the preceding-stage side of the power switch and subsequently detecting, based on a result of detection by the voltage detector with the power switch in the conducting state, an insulation resistance on the succeeding-stage side of the power switch.
