Abstract

The invention discloses an automobile emergency start power source which comprises a 12 V/24 V voltage output module. The 12 V/24 V voltage output module comprises a first set of cells, a second set of cells, a voltage switching unit and two output ports. The nominal voltage of the first set of cells and the nominal voltage of the second set of cells are both 12 V, and after the first set of cells and the second set of cells are connected in series, the two ends are connected with the two output ports respectively; the voltage switching unit is connected with the first set of cells and the second set of cells and used for controlling the first set of cells and the second set of cells to output 12 V voltage or 24 V voltage through the output ports. Compared with the prior art, due to the fact that the automobile emergency start power source is provided with the two sets of cells, the voltage switching unit and the two output ports, one set of output ports selectively output 12 V voltage or 24 V voltage, and the number of output ports needed by the automobile emergency start power source is reduced.

Description

technical field [0001] The present invention relates to the field of mobile power supply technology, and more specifically relates to an emergency starting power supply for automobiles. Background technique [0002] The car emergency start power supply is a multi-functional portable mobile power supply developed for car lovers and business people who travel by car. Its main function is to start the car when the car loses power or cannot start the car due to other reasons. It is a One of the must-have products for outdoor travel. [0003] Since the start-up voltage required by cars is 12V, and the start-up voltage required by large trucks is 24V, the current common car emergency start power supply generally has two sets of (four) output ports, one of which outputs 12V voltage, and the other A group of output ports output 24V voltage. Setting two sets of output ports will increase the volume of the emergency starting power supply of the car. Contents of the invention [0...
