A battery management system of a battery apparatus includes a circuit to which a voltage from a power supply is supplied and configured to be used to manage the battery pack. A processor of the battery management system controls the circuit, measure a voltage supplied from the power supply, and corrects the measured voltage based on a voltage drop occurred in the circuit.

A device for controlling a converter has a first output variable and a second output variable adjusted by a duty of a switching element. The device includes a first controller that generates a first duty based on a first error between a predetermined limitation reference value corresponding to a reference value limiting a size of the first output variable and a measurement value of the first output variable measured at a load of a converter. A second controller generates a second duty based on a second error between a predetermined reference value of the second output variable and a measurement value of the second output variable measured at the load of the converter. A duty determination unit derives a final duty of the switching element based on the first duty and the second duty.

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.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass, a generator, a charger, a hardware controller, and a communication circuit. The driven mass rotates 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 driven mass exists in one of (1) an extended position and (2) a retracted position. The generator generates 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 charger is electrically coupled to the generator and: receives the electrical output, generates a charge output based on the electrical output, and conveys the charge output to the vehicle. The controller controls whether the driven mass is in the extended position or the retracted position in response to a signal received from the communication circuit.

A vehicle device includes at least one calculating logic, at least one electric and/or electronic functional unit, and at least one stored buffer energy source, which is operatively connected to the calculating logic and the functional unit and which is configured to at least partially buffer and/or stabilize a vehicle electrical system voltage of a vehicle electrical system in a normal operating state for supplying power to the functional unit. The vehicle device further includes at least one monitoring unit which is configured, in at least one malfunctioning state, in which the vehicle electrical system voltage drops below a voltage limit value and/or a gradient of the vehicle electrical system voltage exceeds a gradient limit value, to at least partially limit the energy intake of the functional unit and to enable an at least temporary power supply of the calculating logic by the stored buffer energy source.

An innovative power electronic control system suitable for various applications, such as for electric vehicles is provided. The system, in some embodiments, is configured for the purposes of on-board AC fast charging (e.g., single phase or multi-phase) when an object is not in use (e.g., a vehicle is stationary) and use as a drive (e.g., for a vehicle, an EV drivetrain) when in motion. The innovative power electronic control system enables, among others, the ability to obtain fast-charging from existing grid infrastructure.

A system and method are for managing the energy supplied to a transport vehicle. A first and a second source of energy provide electrical energy to power at least one piece of consumer equipment of the vehicle. An intermediate energy transmission system receives electrical energy provided by at least one of the two sources of energy and transfers it to the at least one piece of consumer equipment. An energy conversion-control system applies, at the input of the intermediate energy transmission system, the electrical energy to be provided, adjusted depending on the operational state of the first source of energy and on an input signal indicative of an operational state of the second source. The first source of energy includes an internal combustion engine connected to a permanent-magnet alternator that is placed between the internal combustion engine and the energy conversion-control system.

A power path switching apparatus includes a first terminal unit and a second terminal unit provided in a battery pack that includes a plurality of battery modules, and a switching unit that is provided in the battery pack, and switches a path for supplying power from the battery modules, the first terminal unit and the second terminal unit being disposed away from each other at different positions in the battery pack, and the switching unit switches between a first state in which one of the first terminal unit and the second terminal unit serves as an output path of power, and a second state in which one of the first terminal unit and the second terminal unit different from the first state serves as an output path of power.

An apparatus for providing power to a vehicle's electric power system comprises a converter (602) for converting electric input electricity having an input voltage into output electricity having an output voltage. A sense line (612) is provided for electrically connecting a control unit (611) to the vehicle's electric power system. A power line (613) is for connecting an output of the converter (602) in parallel to the vehicle's electric power system. The control unit (611) is configured to detect a running state of an alternator (201) of the vehicle based on a measurement of a signal on the sense line (612) and control the converter (602) to set the output voltage in dependence on the detected running state.

A power distribution device has a resin part covering a portion of a power line and a portion of a signal line and having a switch adjacent to one surface of the resin part, and a cooling part disposed adjacent to a back surface of the resin part opposite to the one surface. The power line and the signal line each have, inside the resin part, a laid-out portion extending in a planar direction orthogonal to an arrangement direction in which the one surface and the back surface are arranged, and a led-out portion extending from the laid-out portion toward the one surface. The laid-out portion of the power line and the laid-out portion of the signal line are located in a projection area of the cooling unit projected in the arrangement direction, and are separated from each other and arranged in the arrangement direction.
