Abstract
A charging device having a coil for inductive electric charging of a device, in particular of a battery, including a control unit having a temperature sensor for detecting a temperature, the temperature sensor being situated in the area of application for applying the device, and is connected to the control unit, the temperature sensor being situated laterally next to the coil and adjacent to the coil.
Claims12
A charging device, comprising:
- a coil inductive electric charging of a device;
- a control unit;
- and
- at least one temperature sensor to detect a temperature, the temperature sensor being situated in a charging area for applying the device, the temperature sensor being connected to the control unit, and being situated laterally next to the coil and adjacent to the coil.
1 more element
A battery, comprising:
- a coil and an electric circuit for inductively charging the battery;
- and
- a temperature sensor for detecting a temperature, the temperature sensor being situated in a charging area for applying a charging device, and being connected to a control unit;
- wherein the temperature sensor is situated laterally next to the coil and adjacent to the coil.
1 more element
A method for foreign object recognition during an inductive charging procedure of a battery, comprising:
- detecting two temperature values in a charging area with the aid of at least two temperature sensors;
- and
- recognizing a foreign object as a function of one of a difference between the two temperature values, or a difference between temperature changes over time of the two temperature values by comparison with a reference value.
