Abstract

The invention discloses a charging device, and the charging device is used for charging an automobile storage battery or vehicle-mounted equipment. The charging device comprises a power supply module,a main control circuit, a lifting circuit, an adjusting circuit and an output port. The charging device charges the automobile storage battery or the vehicle-mounted equipment through the output port; the power module is electrically connected to the main control circuit and the lifting circuit and used for providing electric energy for the main control circuit and the lifting circuit. The main control circuit is also electrically connected with the adjusting circuit and the lifting circuit, and the main control circuit is used for outputting an adjusting signal to the adjusting circuit; theadjusting circuit controls the lifting circuit to output a first output voltage or a second output voltage to the output port according to the adjusting signal, and the second output voltage is greater than the first output voltage. The invention provides various charging voltages, and can meet the charging demands of the automobile storage battery.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging device. Background technique [0002] At present, automobiles have been popularized in every household. Existing automobiles, even gasoline-powered automobiles, still need batteries. When the car is ignited and started, it supplies power to the car's starting system. The power supply of the car starter, the ignition of the spark plug, the operation of the gasoline pump, the electric injection system and other equipment all need to be powered by the battery during the ignition and start of the engine. Existing batteries are generally lead-acid batteries. The lead-acid battery has a large capacity, generally more than 35Ah. However, in order to meet the needs of charging the car battery and charging the on-board equipment, the existing emergency batteries generally only provide an output voltage that meets the on-board equipment. However, the output voltage of the...
