Problems solved by technology
Before use, the battery clip directly outputs the voltage, or the high current switch needs to be turned on. If it is an emergency power supply that requires two voltage outputs of 12V and 24V, it must be designed with a high current conversion switch, and it needs to be screwed to the corresponding position before use. When the positive and negative poles of the battery clamp are reversed and the high current switch is turned on, the emergency power battery and the external battery will A short circuit is formed, and the output current is extremely large at this time, which will damage the emergency power supply or connected equipment

Description
technical field [0001] The invention relates to a manual-automatic integrated voltage identification device, which can be used for automobile emergency power supply and belongs to the technical field of automobile emergency power supply. Background technique [0002] In the general car emergency power supply, the voltage is directly output by the battery clip, or a high-current switch is designed to avoid hidden dangers such as ignition caused by the short circuit of the battery clip. Before use, the battery clip directly outputs the voltage, or the high current switch needs to be turned on. If it is an emergency power supply that requires two voltage outputs of 12V and 24V, it must be designed with a high current conversion switch, and it needs to be screwed to the corresponding position before use. When the positive and negative poles of the battery clamp are reversed and the high current switch is turned on, the emergency power battery and the external battery will A sho...
