    摘要: PROBLEM TO BE SOLVED: To provide a safety braking system for an electric vehicle, particularly for a rail vehicle equipped with a traction chain. SOLUTION: The system includes: a first brake that is an electric normal brake incorporated in the traction chain (1); and a second brake (2) that is a safety brake. The system is characterized in that it includes: at least one electromechanical commutator (20) which carries out current commutation from the first brake to the second brake; a monitoring device (3) which can monitor braking performance of the first brake based on a measuring current value; a discrimination device (4) for carrying out current commutation from the first brake to the second brake when the measuring current value exceeds the predetermined threshold value (240); and a commutation command transmitter (5) which transmits a commutation command to at least one electromechanical commutator (20).

    摘要: PROBLEM TO BE SOLVED: To provide a vehicle propulsion system used for a battery-drive electric automobile or a hybrid car.
    SOLUTION: The vehicle propulsion system (100) includes an alternate current (AC) traction drive system (147); a first energy storage system electrically coupled to the traction drive system via a direct current (DC) link (114); a second energy storage system electrically coupled to the traction drive system, so as to allow voltage output from the electrical connection to be decoupled from the DC link by using a bidirectional boost converter (120); and an energy management system composed so as to control the first/second energy storage systems, when a vehicle is operated by at least either one mode of a pre-charging mode and a normal operation mode for allowing the traction drive system (147) to effectively function.

    摘要: PROBLEM TO BE SOLVED: To provide a power supply for vehicle which can be operated for a long time without refueling while improving energy efficiency by mounting an energy storage device. SOLUTION: The power supply for vehicle 100 comprises a first energy storage device, i.e. a battery B1, a second energy storage device, i.e. a battery B2, a motor generator MG2 for driving the wheels, a select switch RY0 for connecting one of the first and second energy storage devices selectively with the motor generator MG2, and a controller 60 for controlling switching of the select switch RY0 depending on the charged state of the first and second energy storage devices. If charging is performed when the select switch RY0 is selecting the battery B1 and the charged state of the battery B1 becomes higher than a first predetermined level, the controller 60 directs the select switch to perform switching to the second energy storage device.
