Double-battery management circuit and lamp

Abstract

The embodiment of the invention discloses a double-battery management circuit and a lamp. The circuit comprises: a first power supply unit and a second power supply unit which are connected in parallel, wherein the first power supply unit is used for providing a first power supply current and a second power supply current so as to achieve the power supply operation; a detection unit connected withthe second power supply unit and used for detecting and outputting a real-time voltage value corresponding to the second power supply unit; an judgment unit connected with the first power supply unit, the second power supply unit and the detection unit and used for receiving the real-time voltage value, generating a corresponding control signal based on the real-time voltage value and outputtingthe control signal; and a charging unit connected with the first power supply unit, the second power supply unit and the judgment unit and used for receiving the control signal and controlling the current direction of the first power supply current and / or the second power supply current based on the control signal. The embodiment of the invention further discloses a lamp applying the double-battery management circuit. According to the invention, the continuous power supply control of the lamp can be realized, and the continuity of power utilization is ensured.

Description

Technical field [0001] The invention relates to the technical field of batteries, in particular to a dual battery management circuit and a lamp. Background technique [0002] In all walks of life in modern times, the use of electricity has become more and more important. A momentary power failure can easily cause huge losses. It can be seen that electricity has become an indispensable component in people's lives. However, there are still some devices that need to be powered by batteries. Due to the limitation of battery power, equipment operations may stop. For example, during the video data collection operation of the intelligent lighting operating system, if continuous continuity cannot be maintained The process will lead to interruption of shooting and cause some unnecessary or major losses. [0003] From this, it can be seen that how to ensure the continuity of the electrical equipment to ensure the continuity of the equipment process is a problem to be solved in the prior art...
