Embodiment Construction

[0024] figure 1 It is the overall structural block diagram of the thermal energy harvesting system. The design of the thermal energy collection system includes: thermal energy collector, boost circuit module, IC control circuit module, battery pack, rechargeable supercapacitor, etc.

[0025] The specific embodiment of the present invention is as figure 2 As shown, its overall working process is as follows: the thermal energy harvester converts the heat in the environment into electrical energy, and the IC control circuit module collects the input voltage. If the input voltage reaches the minimum starting voltage of the boost circuit module, the IC control circuit module The module generates a signal to make the boost circuit module work normally. Part of the voltage generated by the boost circuit module is stored in the battery pack through the filter capacitor, and the other part of the voltage is stored in the rechargeable super capacitor through the filter capacitor.

Abstract

The invention provides a heat energy acquisition system. The system is mainly composed of a heat energy acquisition device and an energy management circuit, wherein the heat energy acquisition device is a heating power generator based on a semiconductor, the heat energy acquisition device is capable of converting the heat energy to electric energy, and the energy management circuit is mainly composed of an integrated circuit (IC) control circuit module, a boosted circuit module and a protective circuit. According to the heat energy acquisition system, redundant heat in the environment can be successfully converted to the electric energy to be stored in battery packs and chargeable super-capacitors, and if the temperature of the battery packs is overhigh, charges of the battery packs are in a saturation state or the battery charge current is overlarge during the energy acquisition process, the IC control circuit module can interrupt the battery pack charge state.

Description

technical field [0001] The invention belongs to the field of micro power supply, and is characterized in that it collects thermal energy in the environment, and converts the collected energy into electric energy and stores it in an energy storage element. The main purpose is to supply power for small wireless sensor networks and other low-power devices to improve energy utilization. technical background [0002] Energy and the environment are closely related to the survival and development of human society. With the increasing global awareness of environmental protection and energy conservation, more and more companies have taken the development of new energy as a major strategy to improve industrial competitiveness and maintain sustainable economic and social development. move. Currently, energy harvesting technologies that extract unused energy from the environment (temperature differences, vibrations, etc.) are increasingly becoming competitive solutions in various appli...
