Abstract: An information processing device according to the present disclosure includes a memory and a processor coupled to the memory. The processor is configured to: calculate a risk degree based on information regarding a power consumption amount of a battery mounted on a moving object; and determine an insurance premium according to the risk degree. The risk degree indexes a danger that a charge amount of the battery becomes less than a predetermined amount while the moving object is traveling.

Abstract: A vehicle power unit is operable to, when not driving the starter, charge first and second capacitors. A controller is operable to, when driving the starter, cause the battery to supply power to the starter if a total voltage of first and second capacitor voltages is smaller than a predetermined total voltage. The controller is operable to, when driving the starter, form a parallel circuit of the battery and the first capacitor, and connect the second capacitor in series to the parallel circuit if the total voltage is not smaller than the predetermined total voltage at a beginning of use of the vehicle. The controller is operable to, when driving the starter, disconnect the battery from the starter. The vehicle power unit reduces a load applied to the battery when driving the starter, accordingly extending a life time of the battery.

Abstract: A vehicle power supply device is provided which is capable of improving fuel efficiency by lengthening a period of no-idling even if a main power supply thereof is deteriorated. The device is configured for use in a vehicle having an engine and a load, and includes an electric generator, a main power supply, a starter, a first switch, a power storage part, a second switch, and a control part. In the case of the main power supply being deteriorated, the control part causes the main power supply to supply electric power thereof to the load in the period of no-idling of the vehicle, and the control part controls, when the engine is restarted, such that the starter is driven on both the electric power of the main power supply and regenerative electric power of the power storage part, with the first switch being OFF and the second switch being ON.

Abstract: A load and a first storage battery are connected to a generator, and a second storage battery is connected to the generator via a DC/DC converter, wherein a controller connected to the DC/DC converter, receiving a regeneration signal emitted from outside, controls the DC/DC converter so that the voltage of an input/output terminal becomes the first target voltage that is lower by the first fixed value than the voltage of input/output terminal to which the generator is connected in the DC/DC converter at the time in order to charge the second storage battery, and when regeneration signal reception is ended, the DC/DC converter is controlled so that the voltage of the input/output terminal becomes the second target voltage that is higher by the second fixed value than the voltage of input/output terminal at the time, and thereby, it is possible to enhance the regenerative power recovering efficiency irrespective of conditions during braking.
