This is the world’s first reference design for integrated solar and lithium-ion (Li-ion) battery power systems for small unmanned aerial vehicles (UAVs). By combining Alta Devices’ lightweight solar panel technology with PowerOasis’ expertise in hybrid power systems, small UAV developers can focus on leveraging their core expertise in aircraft design and performance.

“Up until now, it’s been nearly impossible to develop a hybrid solar/Li-ion UAV architecture for small aircraft because the solar technology compromised the design too severely. That is no longer true with Alta Devices’ solar technology,” said Pete Bishop, CTO of PowerOasis.

The reference architecture will target 2-4 meter (6.5-13 feet) span UAVs, using 5s-7s Li-ion batteries. Features include high efficiency, light weight, modular power systems, management of battery packs using a cell vendor agnostic, flexible battery management system (BMS), communication to ground control and on-board auto pilot with continuous real time power and energy data and conditioned power outputs for critical power and payload systems.

“In the past, a UAV manufacturer had to work with multiple companies to obtain the solar technology, downstream electronics, and power management software to create a solar/Li-ion hybrid powered system. Then, they had to design the system themselves,” said Alta Devices Chief Marketing Officer, Rich Kapusta. “By working together and providing a complete architecture for a well-crafted power system, PowerOasis and Alta Devices are streamlining the UAV development process. We are providing a complete system for electric aircraft and UAVs, eliminating the distraction and time required to focus on the intricacies of power design.”

Aircraft designers will be able to use the reference design to manage the complete energy generation, storage and power management system for a UAV. This is without having to bring this capability in-house, saving time and resources than can be better allocated to payload design and aircraft aerodynamics.

Many aircraft companies are turning to solar to provide added endurance to UAVs. A typical battery-powered UAV can normally stay aloft for only a few hours. With solar added to the wings, the same aircraft could fly all day.

The targeted release-date for the design is late 2017 and it will be available initially through Alta Devices and PowerOasis.

PowerOasis is the industry leader in 50W to 20kW hybrid power systems & energy efficiency solutions for a wide range of applications, from telecoms to transport and military deployments, combining in-house power electronics and software expertise enabling bespoke or high volume, high quality, leading edge power solutions.
