Embodiment Construction

[0034] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0035] Such as figure 1 with 2 As shown, a power monitoring circuit 200 includes a comparison unit 210, an adjustable reference unit 220, and an indication unit 230.

[0036] In this embodiment, the power source 100 is a battery, which may be a single battery or multiple batteries.

[0037] The comparison unit 210 has two voltage comparison terminals. One voltage comparison terminal of the comparison unit 210 is electrically connected to the positive electrode of the power supply 100, and the other voltage comparison terminal of the comparison unit 210 is electrically connected to the voltage outp...

Abstract

A power monitoring circuit comprises a comparison unit, an adjustable reference unit and an indication unit, wherein one voltage comparison end of the comparison unit is electrically connected with a positive electrode of a power supply, the other voltage comparison end of the comparison unit is electrically connected a voltage output end of the adjustable reference unit, and an output end of the comparison unit is electrically connected with the indication unit. When the voltage of the power supply is higher than an adjustable reference voltage, the comparison unit controls the indication unit to indicate that power is full; and when the voltage of the power supply is lower than the adjustable reference voltage, the comparison unit controls the indication unit to indicate that power is low. As the adjustable reference voltage is used, the power monitoring circuit can monitor power supplies of different voltages and is highly compatible, and manpower and material consumption is reduced. In addition, a piece of power monitoring equipment is disclosed. According to the power monitoring equipment, two or more power monitoring circuits are arranged to monitor power of a power supply so as to enable the power state of the power supply to be accurately quantified, and the power monitoring equipment is more practical.

Description

【Technical Field】 [0001] The invention relates to the field of battery applications, in particular to a power monitoring circuit and equipment. 【Background technique】 [0002] Lamp lighting can be seen everywhere in modern society. Lamps used in all walks of life have different purposes. However, it is often necessary to add batteries to the lamp mechanism during lamp design. Due to structural limitations and the uncertainty of capacity requirements, use The batteries are different, so that the power monitoring circuit is also endless, causing a great waste of manpower and material resources. [Content of the invention] [0003] Based on this, it is necessary to provide a power monitoring circuit with strong compatibility in view of the problem that power monitoring circuits are also emerging in an endless stream, causing great waste of manpower and material resources. [0004] In addition, in view of the endless emergence of power monitoring circuits, which causes great waste of ma...
