Supercapacitor-based power supply system

Abstract

The invention discloses a supercapacitor-based power supply system. An energy detection module detects current electric quantity information of a supercapacitor in real time; a charging management module transmits a charging request signal to a micro control unit (MCU) when electric energy transferred in a wireless energy transfer way is detected; the MCU acquires the current electric quantity information of the supercapacitor from the energy detection module; when the electric quantity is smaller than a threshold value, the MCU controls the charging management module to charge the supercapacitor; the supercapacitor is connected with a power management module; the MCU is integrated with a wireless communication function; the power management module outputs a stable voltage and a variable voltage; the stable voltage serves as the working voltage of the MCU; and the variable voltage supplies power to external electric equipment. The supercapacitor serves as an energy storage element of a power supply system which is required to work for a long time, and is divided into two paths for supplying the power to a load with a fixed voltage and a load with a variable voltage; the power efficiency is greatly improved; and the problem of supplying the power to implantable medical equipment or the equipment which cannot be contacted directly and is required to work for a long time is solved by charging in a wireless energy transfer mode.

Description

technical field [0001] The invention relates to a power supply system, in particular to an implanted medical device or a power supply system that cannot be directly contacted with long-term working equipment. Background technique [0002] Implantable medical equipment or equipment that cannot be directly contacted and needs to work for a long time, its power supply becomes a key factor that limits its life. In this type of equipment, since the equipment cannot be directly contacted, it is difficult to replace it after it is put into use. When the power supply system fails to work, the equipment cannot continue to be used. [0003] For implantable medical devices, when the power supply system cannot be used, the patient can only undergo surgery again, which brings secondary pain and surgical risk to the patient, and increases the economic burden of the patient. Therefore, providing long-term stable power supply for implantable medical devices is an urgent problem to be solve...
