Abstract

PROBLEM TO BE SOLVED: To provide a power supply system in which a single inverter can charge a plurality of mobiles by providing a switching circuit in the output stage of the inverter.SOLUTION: In the ground facility of a non-contact power supply device consisting of a power supply 1, an inverter 3 connected with the power supply 1 and a primary coil 5 connected with the inverter 3, more than one primary coil 5 for supplying power to the mobile is installed, and a changeover switch 4 is provided between the inverter 3 and the primary coil 5 so that a plurality of mobiles can be charged by a single inverter 3. In this system, priority can be set for an emergency vehicle, or the like, by a method of prolonging the charging time for a vehicle having a high priority, for example.

Description

本発明は、電気自動車及びハイブリッド電気自動車などの非接触給電システムに関わるものである。   The present invention relates to a non-contact power feeding system such as an electric vehicle and a hybrid electric vehicle.

近年拡充されつつある、電気自動車などの給電システムの一つに、非接触給電方法がある。この方式の特徴は、プラグイン方式とことなり、誰にでも簡単に給電することができ且つ雨天時などでも非常に安全に給電することが可能な点にある。   One of power feeding systems such as electric vehicles that are being expanded in recent years is a non-contact power feeding method. A feature of this system is that it is a plug-in system, and can be easily supplied to anyone and can be supplied very safely even in rainy weather.

しかし、非接触給電用インバータは高価であり、充電スタンドに駐車する全台数分インバータを用意するのは経済的でない。   However, inverters for contactless power feeding are expensive, and it is not economical to prepare inverters for all the vehicles parked at the charging station.

そこで本発明は、インバータの出力段にスイッチング回路を設け、非接触給電地上コイルに順次通電することで、同時に複数台の車両に充電可能なシステムを提供する。   Therefore, the present invention provides a system capable of charging a plurality of vehicles at the same time by providing a switching circuit at the output stage of the inverter and sequentially energizing the non-contact power supply ground coil.

当然、緊急車両や、優先度合の高い車両に対して、通電時間を長くするような優先順位をつけることも可能である。   Naturally, it is possible to give priority to the emergency vehicle or the vehicle with high priority so as to lengthen the energization time.

解決しようとする問題点は、複数台の車両に同時給電しようとすると、インバータが高価なためシステム全体が高価なものになる。   The problem to be solved is that if an electric power is supplied to a plurality of vehicles at the same time, the entire system becomes expensive because the inverter is expensive.

本発明は、インバータの出力にスイッチング回路を設け、非接触給電地上コイルに順次通電することで、複数台の電気自動車などの移動体に充電可能なシステムを提供する。すなわち、電源と該電源に接続されたインバータと該インバータに接続された一次コイルからなる移動体用非接触給電装置の地上設備において、前記移動体に給電するための前記一次コイルを２基以上設置し、前記インバータと前記一次コイルの間に切り替えスイッチを設けることによって１台のインバータで複数台の前記移動体に充電可能としたことを特徴とする非接触給電装置とすることである。   The present invention provides a system capable of charging a mobile body such as a plurality of electric vehicles by providing a switching circuit at the output of an inverter and sequentially energizing a non-contact power supply ground coil. That is, two or more primary coils for supplying power to the moving body are installed in the ground equipment of the non-contact power feeding device for the moving body that includes a power source, an inverter connected to the power source, and a primary coil connected to the inverter. Then, by providing a changeover switch between the inverter and the primary coil, it is possible to charge a plurality of the moving bodies with a single inverter.

本発明で一台のインバータで同時に複数台の車両に充電可能で且つ、緊急車両や、優先度合の高い車両に対して、通電時間を長くするような優先順位をつけることも可能である。   In the present invention, it is possible to charge a plurality of vehicles at the same time with one inverter, and to give priority to an emergency vehicle or a vehicle with high priority so as to lengthen the energization time.

本発明の制御方法。（実施例１）The control method of the present invention. Example 1 従来の制御方法。（実施例２）Conventional control method. (Example 2)

インバータの出力段にスイッチング回路を設けることで実現できる。   This can be realized by providing a switching circuit at the output stage of the inverter.

図１は、本発明で、一台のインバータで複数台の移動体に充電可能であり、且つ充電をする順番および充電時間などを設定することにより、優先順位を設けることが可能である。   FIG. 1 shows that the present invention can charge a plurality of mobile units with a single inverter, and can set priorities by setting the charging order, charging time, and the like.

図２は、従来の制御方法で、一車両に一台のインバータが必要であった。   FIG. 2 shows a conventional control method that requires one inverter per vehicle.

電気自動車及びハイブリッド電気自動車などの移動体の電気スタンドとして効率よく稼働させることができる。   It can be efficiently operated as a desk lamp for a moving body such as an electric vehicle and a hybrid electric vehicle.
