ESSEnergy Storage System Experiment Apparatus of Renewable Energy ESSEnergy Storage System Thermoelement and IHInduction Heating

摘要

The present invention provides an educational renewable energy experiment device. For the educational renewable energy experiment device, the device comprises: a solar cell (21) which generates electricity of DC 15-35[Vdc] from sunlight or artificial light; a DC-DC converter unit (30) which boosts the electricity generated in the solar cell (21) to DC 35[Vdc]; an energy storage battery (23) which charges the electricity generated in the solar cell (21) in a range of DC 20 to 35[Vdc]; a bidirectional battery charging/discharging converter unit (50) which reduces voltage to DC 20-35[Vdc] to store the electricity of DC 35[Vdc] output from the DC-DC converter unit (30) in the energy storage battery (23), or boosts DC 20-35[Vdc] in the energy storage battery (23) to DC 35[Vdc]; a grid-connected inverter unit (60) which converts into AC 22[Vac] based on DC 35[Vdc] boosted from the DC-DC converter unit (30) or from the bidirectional battery charging/discharging converter unit (50); and a grid-connected transforming unit (80) which boosts AC electricity output from the grid-connected inverter unit (60) to AC 220[Vac]. According to the present invention, students learn the concepts of renewable energy, especially solar cell generation and thermoelectric element generation at the same time.
