Abstract

This invention is related to an emergency supply, including electric connected control circuit and an accumulator; the control circuit includes the orderly electric jointed external battery monitoring circuit, the driving logic circuit, the auto-backing circuit, the charge control and coulometric detecting circuit, all of which respectively connect the monolithic machine. This invention provides the emergency supply, can automatically judge the positive and negative polarity connection of the equipment battery, provide correct output signal, make the emergency supply detect the present electric quantity of the equipment battery and charge the equipment battery when its electric quantity is inefficient; the usage is convenient, and it has good maneuverability and can detect the control circuit state in spots, and has strong self-protection capacity.

Description

technical field [0001] The invention relates to an emergency power supply. Background technique [0002] The general emergency power supply is mainly composed of a relatively simple control circuit and a battery. The control circuit is an internal battery detection circuit, which detects the power of the device battery, and at the same time, when the power of the applied device battery is insufficient, the device battery can be charged. [0003] When the emergency power supply is connected to the battery of the device, if the positive and negative polarities are reversed, an alarm signal will be generated, and then the current output will be cut off, so that the circuit of the device will not work. Only when the positive and negative polarities are connected correctly, the emergency power supply can work normally, which reduces the operability of the emergency power supply. Contents of the invention [0004] The purpose of the present invention is to provide an emergency...
