  • Patent number: 10923935
    Abstract: A charging apparatus is disclosed that charges a smartphone in a high-speed charging mode or in a general charging mode in consideration of a voltage state of a vehicle battery, or does not charge the smartphone, such that the charging apparatus effectively copes with unexpected situations capable of occurring in the vehicle. Therefore, when a voltage of a battery embedded in the vehicle reaches a constant voltage, the charging apparatus charges the smartphone in a manner that the in-vehicle battery voltage is protected, and no problem occurs in the vehicle when the vehicle starts engine ignition in the future. As a result, the charging apparatus efficiently charges the battery of the smartphone by adjusting the current and the voltage according to a voltage drop situation during a high-speed charging mode or a general charging mode, thereby efficiently charging the smartphone battery without causing overload to the battery.
