Hybrid energy harvesting solutions that combine small photovoltaic (PV) panels with industrial grade rechargeable Lithium-ion (Li-ion) batteries enable long-term power supply solutions for remote wireless devices connected to the IIoT.
Billions of wireless devices will soon be connected to the Industrial Internet of Things (IIoT). While the vast majority of these will be powered by primary (non-rechargeable) lithium batteries, power management challenges can occur when a wireless device has a relatively high daily power consumption. This will prematurely exhaust the primary battery, which can become highly problematic—especially for devices being deployed in hard-to-access locations and extreme environments.
Of all the energy harvesting technologies currently available, the most popular remote power supply solution involves solar PV/Li-ion battery hybrid technology. These two highly synergistic technologies offer a time-proven and increasingly cost-effective solution for powering industrial grade applications, including:
- GPS sensors
- Asset trackers
- Environmental monitoring systems
- Smart agriculture (monitoring moisture, temperature, and rainfall)
- Marine buoys
- Machine-to-machine communication
- Systems control
- Data automation (SCADA) applications
