Power charge and discharge management circuit, manager and management method

Abstract

The invention discloses a power supply charging and discharging management circuit, a manager and a management method, which are characterized in that it includes a main control board, an input terminal, a DC-DC direct current power supply module, an output terminal, a key input module and a display circuit; an input terminal, a DC-DC power supply module, and a display circuit; The DC power supply module, the output terminal, the button input module, the display circuit and the main control board are electrically connected; the input terminal includes the first input module and the second input module, and the DC-DC power supply module includes the first DC-DC power supply module and the second DC-DC direct current power supply module, the output terminal includes the first output module and the second output module; the main control board connects the input terminal, the DC-DC direct current power supply module and the output terminal through multiple MOS switch tubes. The beneficial effect is that the power supply device connected to the input terminal is identified and automatically adapted by the power supply charge and discharge management circuit, and the output terminal is automatically identified and adapted and appropriate output parameters are selected to supply power to the connected battery or electrical equipment, thereby improving the scope of application.

Description

technical field [0001] The invention belongs to the technical field of power supply management, and in particular relates to a power supply charge and discharge management circuit, a manager and a management method with an input power intelligent self-adaptive function and an output voltage and current automatic selection function. Background technique [0002] With the development of the economy, the number and types of electrical equipment and batteries are increasing, and the number and types of corresponding power adapters and chargers are also increasing. In the prior art, there is usually a single correspondence between one type of adapter corresponding to one type of electrical equipment, one type of charger corresponding to one type of battery, and one type of battery corresponding to one type of electrical equipment. Low. Contents of the invention [0003] 1. Technical problems to be solved [0004] In the prior art, one kind of adapter corresponds to one type o...

Problems solved by technology

[0004] In the prior art, one kind of adapter corresponds to one type of electrical equipment, one type of charger corresponds to one type of battery, and one type of battery corresponds to one type of electrical equipment. The actual application is relatively complicated and the utilization rate of equipment is low. Problem, the purpose of the present invention is to provide a power supply charge and discharge management circuit, a manager and a management method, through which the power supply charge and discharge management circuit identifies the power supply device connected to the input end and automatically adapts, and automatically recognizes and adapts at the output end and selects the appropriate output The parameters automatically charge the connected battery or supply power to the electrical equipment, which greatly improves the scope of application and saves people from the trouble of matching the appropriate input power
