Intelligent emergency power supply

Abstract

The invention discloses an intelligent emergency power supply. The intelligent emergency power supply comprises a shell and various kinds of batteries placed in the shell for supplying power for electronic components in the shell; the batteries comprise lead acid, a lithium battery, graphene and the like, a relay, and a controller electrically connected with the battery and the relay; the intelligent emergency power supply comprises an expansion detection protection module, an inversion connection detection protection module, a charging protection module, a low-voltage protection module, a high-temperature protection module, a low-temperature protection module, a sparkproof protection module and a short circuit protection module, so that use safety of the emergency power supply can be ensured effectively; in addition, by matching with an illumination apparatus, a cigar lighter apparatus, an air pump apparatus and the like, the use functions of the emergency power supply can be diversified, more flexible and convenient use is realized, and the battery emergency power supply is safer and more stable in use; and furthermore, the service life is prolonged, and the intelligent emergencypower supply is suitable for intelligent power supply products of various voltages.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an intelligent emergency power supply. Background technique [0002] The Chinese patent No. 201520704897.6 discloses a lithium battery emergency power supply, which includes a lithium battery, a high-current relay, a controller, a temperature sensor and a charging adapter. The temperature sensor constantly detects the internal temperature of the lithium battery and converts the detected data The main circuit board on the controller is electrically connected to the lithium battery. The maximum voltage of the emergency power supply of the lithium battery does not exceed 12.6V±0.1V. The MCU in the main circuit board monitors the voltage of each battery to discharge Open circuit or short circuit. [0003] The emergency power supply provided by the above technical solution enables the lithium battery to have the functions of charging temperature protection, open circuit and sh...

AI Technical Summary

Problems solved by technology

[0003] The emergency power supply provided by the above technical solution enables the lithium battery to have the functions of charging temperature protection, open circuit and short circuit protection, but in the specific use process, there will still be problems with fewer use functions and protection functions: for example, during the use of the product, due to various The occurrence of various uncertain factors will cause damage to the battery. Before the battery explodes and burns, the battery will swell, and the battery will explode if it continues to swell; When the positive and negative poles are connected, if the connection is reversed due to negligence, it is easy to cause the power supply and consumption equipment to burn out, the components will be seriously heated, breakdown, and even deflagration in severe cases
