Inductive charging method for vehicle

Abstract

The invention relates to an inductive charging method for a vehicle. A power supply device and a power receiving device are comprised. The power supply device senses whether the power receiving device enters an inductive range or not through a first frequency conversion power supply module corresponding to a first power receiving module of the power receiving device. A power supply microprocessor compares whether an identity identification code from the power receiving device allows power supply or not, examines whether the power receiving state data code is in a normal power supply state or not, and marks a system state of the power receiving device as an error state by the power supply microprocessor. A signal control circuit transfers the state to other first frequency conversion power supply modules to close power output, and the power received is examined and the output power is adjusted through the power receiving state data code. As the power receiving module in series improves the total voltage for charging the vehicle, operations such as identity identification, value storage or value reduction can be carried out through data transmission manner, so that the purposes of cost reduction, convenience in use, and leakage and electricity stealing prevention are further realized.

Description

technical field [0001] The present invention provides a vehicle inductive charging method, in particular, the frequency conversion power supply module in the power supply device is connected to the signal control circuit and the power supply source, and the power receiving device connects the voltage dividing circuit and the power receiving output terminal with the power receiving module in series inside. Let the vehicle carry out charging, identification, voltage comparison, power adjustment and data transmission in an inductive way, so as to achieve the effects of convenient use, anti-leakage and anti-theft. Background technique [0002] Generally, most electric vehicles are equipped with batteries inside the vehicle. When the battery power is exhausted or not enough for use, the vehicle needs to be charged. However, since the charging method is to use a power cord and a plug to electrically connect the vehicle, when setting up a charging station When charging, not only is...

Problems solved by technology

[0004] (1) Because the voltage output by the power receiving end is obtained by the voltage on the power receiving coil through the procedures of rectification, filtering, and voltage stabilization, these procedures will reduce the processed voltage, so the voltage on the power receiving end If the demand for output voltage increases, the voltage obtained by the power receiving coil at the front end needs to be increased to a very large level, and the rectification element at the rear end must also be a high withstand voltage voltage element, because the high voltage withstand element is very expensive and difficult to produce, resulting in the actual Difficult and expensive to do

[0005] (2) The coil at the power receiving end needs to obtain high voltage, which means that the power supply end also needs to drive high voltage to the power supply coil to transmit power, and in this case, the driving element at the power supply end also needs to be a high voltage driving element, because the drive High-voltage components are very expensive and difficult to produce, making implementation quite difficult and costly

[0006] Therefore, how to solve the high cost and high difficulty problems and deficiencies caused by the increase of the output voltage of the receiving end of the existing inductive charging technology is the direction that relevant manufacturers engaged in this industry are eager to study and improve.
