Battery harvesting versus energy harvesting

摘要

Should you use primary batteries or energy harvesting for your low power isolated from the grid application? Are primary batteries better or worse than energy harvesting? Can you use one or the other or do you need both? Neither? It is an interesting question depending on the application, the power required and the costs involved. So let us explore the field and see if we can determine a set of rules that will help us come up with a final answer. Stored energy (batteries)? Harvested energy? Neither? Both?
