Principle
In this experiment, wind energy and solar energy are stored in a rechargeable battery. When energy production becomes too low, the battery uses its stored energy to power a lamp, demonstrating how stored energy can be used to cover energy demand during periods of insufficient generation.
Tasks
- Charge a rechargeable battery using solar and wind energy.
- Power an incandescent lamp using the stored energy when insufficient energy is being produced.
- Program the switching processes with Cobra SMARTsense Code so that they operate automatically.
Learning objective
Learners discover that surplus energy from renewable sources can be stored and used again at a later time. They are also introduced to simple programming of a device for voltage and current monitoring as well as relay switching.
Benefits
- Programming of the Code Actuator using the Blockly programming language or a trigger function.
- Contact-safe design through puzzle-like interlocking modules.
- Use of standard Cobra SMARTsense sensors for teaching in schools and universities.
- Safe experimentation: the lamp is protected against accidental contact, the housing is well ventilated through ventilation openings, and it heats up only slightly.
- The power supply used is versatile and particularly suitable for student experiments at all educational levels ("RiSU 2016 compliant").
