Description
本考案は、自動車の電池や発電機の電力を利用して、リチゥム・イオン電池を充電する、充電器に関するものです。 The present invention relates to a charger for charging a lithium ion battery using the power of a battery of a car or a generator.
従来の電池充電器は、家庭電源の１００ボルトを降圧回路で電圧を下げて充電するように造られていて、屋外での充電ができず、充電電池を使用した電気機器の屋外使用が制限され、特に災害場所では、不便を感じていました。 Conventional battery chargers are designed to charge a household power supply of 100 volts by lowering the voltage with a step-down circuit, which cannot be charged outdoors, and the use of electric equipment using rechargeable batteries is restricted. I felt inconvenience, especially in disaster areas.
災害場所で、自動車の電池や発電機の電力を利用して、リチゥム・イオン電池を充電する充電器の開発 Development of a charger that charges lithium-ion batteries using the power of automobile batteries and generators in disaster areas
自動車の電池や発電機の電力を利用し、電池を充電する方法。
普通小型自動車の電源電圧は、電池は１２ボルトで発電機は１３，８ボルト、トラックや工事現場の大型自動車の電源電圧は、電池は２４ボルトで発電機は２７，６ボルトになっています。
最適充電電圧２０ボルトから２４ボルトを確保するのに、小型車用は昇圧回路で電圧を高く、大型車用は降圧回路で電圧を下げて、定電流・定電圧充電回路でリチゥム・イオン電池を充電するようにした。A method of charging a battery using the power of an automobile battery or generator.
The power supply voltage for ordinary small vehicles is 12 volts for batteries and 13.8 volts for generators. The power supply voltage for large vehicles on trucks and construction sites is 24 volts for batteries and 27.6 volts for generators.
In order to secure the optimal charging voltage of 20 to 24 volts, the voltage is increased by the booster circuit for small vehicles, and the voltage is decreased by the step-down circuit for large vehicles, and the lithium ion battery is charged by the constant current / constant voltage charging circuit. I tried to do it.
自動車の電池や発電機の電力を利用し、特に災害場所で電気機器の電池充電が繰り返しでき、屋外での充電電池使用電気機器での作業が楽になった。 Using electric power from automobile batteries and generators, battery charging of electrical equipment can be repeated, especially in disaster areas, making it easier to work with electrical equipment using rechargeable batteries outdoors.
