Abstract

The invention discloses a power management device and method with multi-energy input and multi-channel adjustable output. The device includes an input module, which converts multi-energy types into electrical energy through a transducer; an energy storage module, which includes a super capacitor energy storage unit and a The lithium battery unit is used to receive the electric energy converted by the input module, and also includes a battery management unit, which protects the lithium battery and the capacitor energy storage from overcurrent, overcharge, overload and short circuit; the processing module is connected to the energy storage module , reasonably select the input energy type and optimally distribute the load power according to the external working environment, and display the working parameters of the current system in real time. The voltage regulation is used by the external load, and the output voltage is monitored in real time by the feedback circuit.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to a power management device and method with multi-energy input and multi-channel adjustable output. Background technique [0002] In a distributed test system, the locations of test nodes are scattered, and for a system that requires long-term monitoring, the selection and management of power supply is crucial. The power supply mode of the traditional distributed test system is relatively simple. Generally, wired power supply or battery power supply is used. Wired power supply is often unavailable in distributed test systems. In practical applications, long-term monitoring devices are mainly powered by batteries. The capacity of the battery itself is limited, so in order to prolong the battery life of the monitoring device and reduce the number of battery replacements, the application function of the test system can only be selectively reduced. Therefore, the batte...
