A method and device for preventing reverse connection of 4 dry batteries connected in series

Abstract

The invention provides a method and device for preventing the reverse connection of 4 dry batteries connected in series. The method for preventing the reverse connection of 4 dry batteries connected in series is as follows: detecting the voltage value at both ends of the dry battery, and acquiring the voltage value every certain time, continuously Obtain a certain number of times and compare the obtained voltage value with the preset voltage. At the same time, count the number of times the obtained voltage value is lower than the preset voltage. If the number of times of low voltage is greater than a certain number of times, the device will not be turned on, otherwise the device will be turned on. The device for preventing reverse connection of four dry batteries in series mainly includes: a voltage acquisition module, an acquisition times counting module, a voltage comparison module, a low voltage times counting module, an acquisition times comparison module, and a low voltage times comparison module. The invention solves the problems of abnormal phenomena, current loss, waste of power consumption and shortening the service time of the equipment caused by the accidental reverse connection of the dry battery when the equipment is not turned on, and simultaneously acquires the voltage value multiple times to ensure the accuracy of the detection results. precision.

Description

technical field [0001] The invention relates to an application field in which dry batteries are connected in series to supply power to loads, in particular to a method and device for preventing reverse connection of four series connected dry batteries. Background technique [0002] In the new era of the 21st century, electricity has become an indispensable part of people's daily life. Daily necessities such as remote controls, electric razors, and mobile phones all need batteries to provide power. At present, in the equipment powered by 4 dry batteries connected in series on the market, after the batteries are accidentally reversed, including 1, 2, 3 or 4 reversed connections, there will be a voltage difference between positive and negative, and some are positive voltage differences. , some are zero pressure difference, some are negative pressure difference. Positive voltage difference will cause the chip with working voltage difference to work, and negative voltage differe...

AI Technical Summary

Problems solved by technology

Positive voltage difference will cause the chip with working voltage difference to work, and negative voltage difference will cause the loss of front-end current, which will lead to abnormal phenomenon or waste of power consumption when the device is not turned on, and even shorten the use of the device. duration, which in turn causes users to doubt the parameters in the product manual
