How will remotely located IoT devices be powered in the future? In this excerpt from “Internet of Things for Architects,” Perry Lea takes a look at the significant problems IoT designers will face when resolving issues about energy sources and power management for IoT devices.
Important points about powering wireless devices:
- Self-discharge must be accounted for;
- Most rechargeable batteries have limited cycle lives and see significant capacity fade over time;
- Supercapacitors suffer from capacity leakage;
- Energy density is very important.
