The automotive market is very competitive, for this reason it has to increasing the performance of each of the basic elements of the car. The mirrors has gone from being inert elements that do not consume energy to has dispose of actuators and sensors that need to be fed. The features that have these elements are different: · Electrochrome glass. · Power folding. · Glass regulation (Glass actuator). · Heating to prevent ice or condensation (Heater). · Blinker. · Daylight (DRL). · Blind Spot Detector (BSD). · Puddle Lamp. The mirrors are exposed to atmospheric factors and must pass a extreme quality tests for go out to the market. Overcoming these tests depends of a lot of attributes, one is be watertight, this attribute is reduced by connecting electrical cables. This project proposes to replace these electrical connections for wireless power systems and wireless communications. Power is transmitted by magnetic induction following the international standard Qi (Wireless Power Consortium). Moreover, the drive control unit (Electronic Control Unit, ECU) Zigbee transceivers used to send control commands to the actuators. Currently, there are a large number of manufacturers of integrated circuits at the Qi standard. We used one of these circuits, specifically bq500215 to the power transmitter and the bq51025 to the power receiver. The system implemented can transmit a maximum power of up to 10 W with an efficiency which can be 80%, through an isolation barrier of 5 mm. This project was implemented in the company Idneo Techonologies SL, within the Department of Hardware Auto.
