An emergency starting power supply

Abstract

The invention provides an emergency starting power supply, which includes a battery assembly, a main control board, a casing, a positive clip, a negative clip and a telescopic cable, the battery assembly is connected to the main control board; the positive clip is connected by a telescopic cable connected with the main control board, the main control board is connected with the positive pole of the battery assembly; the negative clip is connected with the negative pole of the battery assembly through another telescopic cable; the main control board includes an output voltage A control module and a voltage identification module, the output voltage control module and the voltage identification module are used to perform adaptive power supply. Compared with the prior art, the present invention has the beneficial effects that the emergency starting power supply can be adaptively output, has good convenience and safety in use, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an emergency starting power supply. Background technique [0002] The existing 12V / 24V dual-voltage output type emergency start-up power supply uses two isolated battery packs as the voltage output source. In addition, in order to match the two sets of power supplies, two sets of different split clips are also set up. When the emergency starting power supply is applied successively to vehicles with different battery rated voltages, special attention should be paid to whether the selection of split clips is correct. In other words, a vehicle with a battery rated at 12V and a vehicle with a battery rated at 24V are to be started with different split clips. In addition, the split clip is inconvenient to carry. [0003] All in all, this kind of emergency starting power supply is inconvenient to use, and it is very easy to reverse it. This kind of emergency starting power s...
