Definitions

  • the present invention relates to the field of motor vehicle equipment, particularly that of thermal/electric hybrid vehicles (including an engine, usually with internal combustion, and at least one electric machine) or electric vehicles, and is intended for transmission, such as double clutch transmission (DCT/PDK) , continuous variable transmission (CVT) or automatic planetary transmission.
  • DCT/PDK double clutch transmission
  • CVT continuous variable transmission
  • automatic planetary transmission such as double clutch transmission (DCT/PDK) , continuous variable transmission (CVT) or automatic planetary transmission.
  • the present invention specifically relates to an integrated wireless charging system for an electric and/or hybrid vehicle, more specifically to an (automatic) transmission system comprising such an integrated inductive wireless charging system.
  • the charger plate With inductive charging, the charger plate is planted in the ground, for example beneath the surface or on the surface of the road leading to the house or in the garage.
  • Plate filler consists of coils that generate magnetic fields when energized by electrical current.

  • DC direct current
  • a disadvantage of known systems is the use of stand-alone components that need to be mounted somewhere in the vehicle. This also involves extra factory assembly time to mount and connect the receiver in the vehicle. This may lead to extra costs and service mistakes. Another disadvantage arises when the system is malfunctioning and needs to be replaced. Several units must be dismounted and replaced. This is very time-consuming and costly and needs a good knowledge of the specific system. Existing inductive systems have a high cost and are heavy since there is a need for extra components to protect, connect and to cool down.
  • Some existing stand-alone receivers are cooled with forced air from e.g. the ventilator of the powertrain, which needs extra power and reduces the charging efficiency.
  • the purpose of the present invention is to provide a solution to at least one of the aforementioned and other disadvantages, by providing a wireless charging system for an electric or hybrid vehicle comprising a vehicle transmission unit, an electromotor, one or more batteries to power the electromotor, and an induction receiving device mounted in the vehicle for charging said one or more batteries, the induction receiving device being able to cooperate with a charging device mounted in an area in the ground/surface to allow for proximity placement to the bottom of the vehicle, preferably located between the wheels of the vehicle while driving or stopping, whereby the induction receiving device is integrated in or on an existing system of the vehicle such as the drive train, invertor or battery.
  • the induction receiving device is integrated in or on the vehicle transmission unit.
  • integrated means attached to or built in or being part of or having similar dimensions or providing space to house.
  • the existing system of the vehicle e.g. the transmission unit, comprises an induction receiving device.
  • vehicle means a car, a bus, a truck, or any other transport vehicle.
  • Such a system has the advantage that the inductive plate ⁇ receiving device) is integrated in the transmission or the existing system as one unit. Maintenance and repair becomes much easier, because only the existing system needs to be handled and not the receiving device as such.
  • the existing systems are already as such that maintenance and repair is known.
  • the charging system is provided in a unit that is already equipped with the necessary power supply, cooling and housing.
  • the integration of the receiver in the transmission unit allows to use its existing components like a high amount of heat conducting metal, oil pump and transmission oil to improve the heat dissipation. Its integration also replaces the expensive plugs by more cost effective internal connections. A weight reduction will be achieved by using the existing housing of the transmission e.g.. The usage of transmission oil to improve the conduction speed of the power losses from the hot spot of the electronics to cooler surroundings is very effective. By integrating the receiving device in an existing system with better cooling performance and possibilities like a transmission or invertor or battery, less extra cooling losses are obtained.
  • an integration of the induction receiving device in the transmission e.g. would support the world wide standardization of the inductive charging, boost the production and lower its cost.
  • the receiving device is integrated at the lowest point of the transmission unit.
  • the "lowest point” meaning the closest to the area on which the vehicle drives, or closest to the bottom of the vehicle .
  • the receiving device is fitted to the transmission unit underneath said transmission unit.
  • "Underneath" meaning that the receiving device is fixed to the transmission unit at a point that is closest to the area on which the vehicle drives, or closest to the bottom of the vehicle.
  • the induction receiving device is fitted in the oilpan of a hydraulic transmission unit .
  • the transmission unit may be any design of a transmission unit) , such as a double clutch transmission (DCT/PDK) , a continuous variable transmission (CVT) or an automatic planetary transmission.
