Problems solved by technology

If the user buys a replacement battery by himself, he may buy a battery whose positive and negative poles do not match the positive and negative polarity of the battery slot interface of the mobile phone. When such a battery is buckled on the mobile phone, it will cause a short circuit and a large current, which will burn the main board of the mobile phone , resulting in irreparable damage

Embodiment Construction

[0062] In order to make the purpose, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be described clearly and completely in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments These are a part of the embodiments of this application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0063] The embodiment of the present application provides a battery connection circuit, which is applied to a device with a battery installed. The battery connection circuit may not distinguish between the positive and negative electrodes of the battery, and both can output a positive voltage to the positive input terminal of the device and input to the negative electrod...

Abstract

The invention relates to a battery connection circuit and application equipment thereof. The circuit comprises a first polarity end, a second polarity end, a positive end, a negative end, a first conversion circuit and a second conversion circuit. When a first unidirectional conduction device and a third unidirectional conduction device are in the conduction state, a second unidirectional conduction device and a fourth unidirectional conduction device are in the off state. When the second unidirectional conduction device and the fourth unidirectional conduction device are in the conduction state, the first unidirectional conduction device and the third unidirectional conduction device are in the off state. After adjustment of the battery connection circuit, the positive end output of the battery connection circuit is ensured to be always positive and the negative end output is ensured to be always negative, thereby alleviating the problem in the prior art that the positive and negativepolarity of the battery does not match the equipment.

Description

Technical field [0001] This application relates to the field of device application, and in particular to a battery connection circuit and its application equipment. Background technique [0002] In recent years, the emergence of smart phones has greatly facilitated the lives of the people, and with the development and innovation of science and technology, smart phones have more and more functions and more and more application fields. [0003] In the circuit design of mobile phones, the bottleneck of mobile phone batteries is still lagging behind the development of smart phones in other directions. At present, after about a year of use, the battery of a smart phone will suffer more and more serious usage loss and shorter life span. Many users will choose to replace the battery to get a better mobile phone experience. [0004] Normally, different manufacturers have different specifications for the positive and negative electrodes of the batteries. For example, some manufacturers’ batt...
