A vehicle onboard power supply system, supplying a consumer with electrical energy, includes a first voltage detection device (55) detecting a voltage level in a line area (51) between an input terminal (34) of a first circuit breaker (26) and a first battery (16), a second voltage detection device (57) detecting the voltage level in a line area (53) between an input terminal (42) of a third circuit breaker (30) and a second battery (18), a third voltage detection device (58) detecting the voltage level in the area of a consumer connection line (12). An overvoltage detection device (62) detects an overvoltage in the area of the consumer connection line based on the voltage level detected by the third voltage detection device and switches the first circuit breaker and the third circuit breaker into open states when overvoltage is detected in the area of the consumer connection line.

Each circuit breaker (32, 34) allows in a conductor state, the flow of current between its input terminal (E1, E2) and its output terminal (A1, A2) in both directions, and it allows a flow of current only from the input terminal (E1, E2) to the output terminal (A1, A2) in a diode state. The output terminal (A1) of the first circuit breaker (32) is connected to the first network (12), the input terminal (E1) of the first circuit breaker (32) is connected to the input terminal (E2) of the second circuit breaker (34), and the output terminal (A2) of the second circuit breaker (34) is connected to the second network (16). There is a third network (16) with a third voltage source (26) and with a third group (G3) of electrical consumers (28). The input terminal (E1) of the first circuit breaker (32) and the input terminal (E2) of the second circuit breaker (34) are connected to the third network (16).

An ECU performs processing including obtaining a current in a battery assembly, calculating a current in each battery, calculating an SOC of each battery, calculating an OCV of each battery, calculating ΔOCV, calculating an average value Ave of ΔOCVs, carrying out current restriction control when the average value Ave exceeds a first range and exceeds a second range, providing a warning signal when the average value Ave does not exceed the second range, and carrying out normal current control when the average value Ave does not exceed the first range.

A system includes a first, particularly mobile, unit which has a number m of function terminals, a first potential equalization terminal, which is intended to be galvanically connected to a reference potential, an energy source, a power converter, which is fed from the energy source and produces a number m of signals, a switching unit, the signals produced by the power converter being fed to the input side of the switching unit, and the output side of the switching unit being connected to the function terminals, or the input side of the switching unit being connected to the energy source and the output side of the switching unit being connected to the power converter, an insulation monitoring unit, which detects an undesired galvanic connection of a component of the system to the reference potential, and a connection monitoring unit, which monitors whether the first potential equalization terminal is properly electrically connected to a corresponding potential equalization terminal of a second unit to be connected to the first unit.

A control device includes an electric motor, a battery, a capacitor, a power source selection portion, a determination unit configured to determine whether the battery is normal, and a control unit configured to select, as a control mode of the electric motor, one of a first mode and a second mode in which a power consumption amount of the electric motor is reduced as compared to when the electric motor is driven in the first mode, and drive the electric motor in the selected control mode. When the battery is transitioned from a state of being determined to be normal to a state of being determined to be not normal, the control unit switches the control mode from the first mode to the second mode and then makes the power source selection portion select the capacitor.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus can comprise a driven mass, a generator, a capacitor storage device, and a battery storage device. The driven mass can rotate in response to a kinetic energy of the vehicle and is coupled to a shaft such that rotation of the driven mass causes the shaft to rotate. The generator can generate an electrical output based on a mechanical input coupled to the shaft such that rotation of the shaft causes the mechanical input to rotate. The capacitor storage device can receive at least a portion of the electrical output from the generator. The capacitor storage device can store at least the portion of the electrical output. The capacitor storage device can convey at least the portion of the electrical output received from the generator to the battery storage device.

A hybrid power backup system having at least one battery for powering at least one external load; at least one capacitor for powering a controller configured to control power provided from the battery to the at least one external load and to control discharge/charge cycles of the battery.

At least one power line is connected to a battery mounted at a vehicle. Plural ECUs are each connected to the at least one power line. A processor switches one ECU at a time of the plural ECUs from a second state to a first state by sending state switching signals to the plural ECUs. A power line to which plural ECUs are connected is a target power line. On the basis of current values of the target power line measured by a current measurement section when these plural ECUs are switched to the first state one at a time, the processor determines whether or not each ECU is in an abnormal condition.

A battery abnormality warning method involves detecting an abnormality in a vehicle-mounted battery and warning an occupant in the vehicle. The battery abnormality warning method determines whether a pressure abnormality has occurred in the battery based on an air pressure inside a battery pack of the battery. The battery abnormality warning method further determines whether a voltage abnormality has occurred in the battery based on a cell voltage of the battery. An abnormality is determined to have occurred in the battery when both a pressure abnormality in the battery and a voltage abnormality in the battery are determined to have occurred within a prescribed time period. A warning is outputted to the occupant in the vehicle upon determining that an abnormality has occurred in the battery.
