Abstract

The invention provides a vehicle-mounted unit kinetic energy power supply method and device. The method comprises the steps that an impact hammer generates impact hammer displacement when an automobile accelerates and decelerates; a rack generates rack displacement by utilizing impact hammer displacement; a gear rotates by utilizing the rack displacement to drive a rotor of a motor to rotate; themotor generates electric energy by utilizing a stator and the rotating rotor; an electric energy output unit converts alternating current generated by the rotors rotating in different directions intodirect current to be output; a super capacitor acquires the direct current output by the electric energy output unit and stores the acquired electric energy; a battery supplies power to the vehicle-mounted unit when the vehicle-mounted unit is in the first state; and the battery and the super capacitor supply power to the vehicle-mounted unit at the same time when the vehicle-mounted unit is in the second state. Therefore, the electric energy is generated by utilizing the kinetic energy of the automobile in operation and is stored through the super capacitor, so that the electric energy storedby the super capacitor and the battery supply power simultaneously when the battery cannot meet the subsequent load use, and the power demand is met.

Description

Technical field [0001] The present invention relates to the field of intelligent transportation technology, and in particular to a method and device for kinetic energy power supply of an on board unit (OBU). Background technique [0002] In the field of intelligent transportation, the existing non-stop collection and payment system requires the installation of an on-board unit OBU in the car for security authentication during transactions and for reading and writing user IC cards. Currently, photovoltaic panels are usually used to convert solar energy into electrical energy to supply power to the OBU. However, the photocell is greatly affected by weather factors. In the case of poor light, there may be insufficient power supply. [0003] In addition, for the existing on-board unit OBU that uses battery for power supply, when IC card reading is performed, insufficient battery energy will also cause card reading failure. Therefore, there is an urgent need for a better power supply ...
