In-vehicle battery charging system

摘要

An in-vehicle battery charging system adaptable to a wide variety of objects to be charged. A charging system 1 includes a battery charger 3 with a built-in primary coil 2 used to charge an object 7 with a secondary coil 5 and a rechargeable battery 6. By allowing the battery charger 3 and the object 7 to come close to each other, the rechargeable battery 6 is charged through an electromagnetic inductive action between the coils. The battery charger 3, provided in a vehicle instrumental panel 4, includes a slider assembly 23 for adjusting a position of the secondary coil 5 of the object 7 with respect to the primary coil 2 of the battery charger 3. This slider assembly 23 enables a positional relationship between the coils to be properly adjusted, enabling a proper charge condition to be maintained for a variety of objects to be charged.

主权项

1. An in-vehicle battery charging system for charging an object including an energy receiving unit and a rechargeable battery, comprising:
a battery charger with an energy transmitting unit, the battery charger being provided in an instrumental panel of a vehicle and including a mounting surface on which the object to be charged is mounted with a surface of the object contacting the mounting surface, thus charging the rechargeable battery, using an energy received by the energy receiving unit from the energy transmitting unit; and a holding unit for adjusting a position of the energy receiving unit of the object to be charged with respect to the energy transmitting unit of the battery charger, wherein the mounting surface is tilted forward in a travelling direction of the vehicle, and the holding unit is provided, on the mounting surface, slidably movable along the mounting surface in such a fashion that a vertical position of the holding unit is adjustable, wherein a recess is formed in an upper portion of the mounting surface, the recess being formed into a size large enough for an upper portion of the object to be charged to get thereinto when the upper portion of the object is pushed toward the recess such that a lower portion of the object is disengaged from the mounting surface, and wherein a housing portion for housing and mounting the object to be charged is provided in a central portion of the instrumental panel of the vehicle, the housing portion being provided with the mounting surface.
