Definitions

  • This invention relates to battery propelled vehicles and control systems for them. According to the present invention, an electric battery-propelled vehicle control system
  • 5. includes an electric traction motor for propelling the vehicle, a main storage battery for supplying the motor, a variable D.C. - high frequency - D.C. converter and switch means having a charging position in which it connects
  • control system includes an input rectifier having input terminals for connection to a A.C. supply at a charging point, and output terminals affording a D.C. supply, and the variable converter includes
  • a high-frequency inverter for producing a variable output high-frequency, for example at 20 or 25kHz supply from a D.C. supply, and an output rectifier connected through an isolating transformer to the output of the inverter.
  • apparatus included a transformer having a low voltage winding connected to the battery through a first inverter for driving, and through a first rectifier for charging, and a high voltage winding connected to the motor through a second rectifier for driving, and to
  • the same inverter and the same rectifier are used in association with a high frequency transformer in the converter for both driving and charging.
  • the equipment comprises a D.C. to D.C. converter 10 of high frequency switched mode type incorporating
  • the converter inverts a D.C. input at its input terminals 21 to a supersonic frequency alternating voltage (for example at 25 KHz) whose wave form may be square., quasi-square, or sinusoidal, and is applied
  • the secondary winding of the transformer is connected to the output rectifier providing a D.C. output at output terminals 22.
  • the converter 10 co-operates with an uncontrolled
  • input rectifier bridge 11 for connection to a single- phase or three-phase A.C. mains supply 12 at a vehicle charging point, a traction battery 14, a traction motor 15, a voltage and current monitor unit 16, a charge control unit 17, and a motor control unit
  • a multipole change-over switch has a charging position 'A' and a driving position 'B' .
  • the battery charging current and voltage are monitored and fed back to the light current circuitry 17 which controls the charge characteristic.
  • the charger is suitable for programming with any type of charge characteristic and charge termination.
  • the semi-conductor devices contained in the converter must, of course, be sufficiently highly rated to withstand both charger and controller operation. Normally, maximum voltage is experienced in the charger mode whilst maximum current occurs in the
  • the drawing shows a scheme for a conventional series-wound traction motor; more sophisticated vehicles are propelled by separately-excited machines of which the field and armature windings are supplied
