Problems solved by technology

This patent application solves the output of various voltage levels and has a self-charging function, but it does not have a large current output capability and cannot be used as a car starting power supply. In addition, the current output in this application document is all DC after output, but in reality , there are also many external devices that need to input AC power, so this patent application cannot solve the temporary power supply problem of such devices

Abstract

The invention relates to an emergency power supply which comprises a shell body. A battery pack used for storing electric energy is arranged in the shell body, and an input end of the battery pack is connected with output ends of a charging circuit used for charging the battery pack and a solar panel input circuit. An output of the battery pack is connected with a large current output circuit used for outputting large currents when an automobile is started, and an externally connected battery intelligent detecting system is connected between the battery pack and the large current output circuit. The emergency power supply is convenient to charge, capable of outputting large currents for starting an automobile, and capable of accurately controlling current output.

Description

technical field [0001] The invention belongs to the field of DC power supplies, and in particular relates to an emergency power supply that can provide power for various devices. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, cars, mobile phones, computers, digital cameras, etc. have become necessary items for people's life, travel and travel. Function, bring a lot of inconvenience to people's life. Therefore, corresponding to each product, the manufacturer provides a corresponding charger, which can convert the 220v mains power into a DC power supply of the corresponding voltage to charge it, but this charger cannot meet the needs of outdoor charging. Especially for automobiles, the problem of not being able to start the ignition is often encountered, especially for automobiles on the road, it is difficult to start the ignition because the battery power is insufficient or the temperature ...
