DEVICE FOR TEMPERATURE ESTIMATION AND METHOD OF TEMPERATURE ESTIMATION FOR A NO-TOUCH DEVICE FOR POWER RECEIVING Russian patent published in 2018 - IPC B60L11/18 B60L3/00 H01F38/14 H02J50/12 H02J50/90 H02J7/02 

FIELD: electronic equipment.

SUBSTANCE: group of inventions refers to systems for wireless charging of battery. Estimator of temperature for the no-touch power pig receiver comprises receive unit of power losses on transmitting side, unit for receiving position shift interval and temperature estimator. Unit for receiving position shift interval receives interval and interval of plane position shift between transmitting and receiving coils and determines compensation factor based on the interval and the interval of plane position shift. Temperature estimator estimates environmental temperature for receiving power coil based on predetermined amount of generated heat of power receiving device and power losses of the transmission coil. In this case, when positional relationship between coils is shifted from normal positional relationship, temperature estimator changes contribution to temperature increase, multiplying the loss of power of transmitting coil by compensation factor. Method for estimating temperature for a no-touch power receiving device is also claimed.

EFFECT: technical result is to improve the accuracy of estimating environmental temperature for receiving coil.
