Over twelve months ago, ultra-fast charging (UFC) pioneer, StoreDot, achieved a world first with its partner, BP, by successfully fully charging a two-wheeled electric vehicle in just 5 minutes. The company more recently launched its UFC technology for the drone industry, having achieved its mission of fully-charging a commercial drone in five minutes – another world first. This milestone overcomes two major barriers associated with slow charging times that has prevented the drone industry from realizing its full potential and could finally make continuous, fully autonomous drone operation a reality.
Today, it typically takes between 60 to 90 minutes to charge a commercial drone, with full charge giving a flight time of just over 30 minutes. As a result, drones spend far longer in the charging station than in operation – an unacceptable level of downtime for any application. To overcome this problem, additional batteries must be purchased and swapped out between flights. This process is not only costly, but also requires a ‘man-in-the-loop’ to replace the batteries, which ultimately negates one of the main benefits of drone use – autonomous operation.
The need for a person to be involved in the charging process also limits drone users’ range of operation, as they are restricted to locating charging stations at sites that are easily accessible to humans. This means that drones currently have to spend much of their limited flight time traveling to and from the nearest charging point, greatly reducing their operational efficiency. It also restricts the use of drones in harsh or dangerous terrains – often where they could bring the greatest benefits.
According to Dr. Doron Myersdorf, CEO of StoreDot, “The launch of a UFC solution for drones changes the game. By reducing battery charging time to just 5 minutes – which is up to 18 times faster than existing drone batteries – and eliminating the need for human intervention, drone operators have far greater freedom about where they can site charging stations. As a result, continuous, fully autonomous drone operation is finally being made a reality.”
“Drones will now be able to spend much more of their valuable flight time engaged in actual missions, greatly extending their range, rather than having to return to base to have their battery swapped out. At the same time, UFC will also enable drone users to expand their operations into regions they could not previously access. Both of these factors will significantly increase operational efficiencies and profitability, making the business case for drone use much more attractive than ever before.”
When used with the required ultrafast charging station, StoreDot FlashBattery technology reduces drone charging times with very little tradeoff in terms of energy density, meaning that flight time is only slightly reduced. Crucially, this is achieved at a price point that is competitive with existing drone battery technology when the total cost of operation is considered. Sample cells are now available to drone manufacturers for testing, with full commercialization expected end of this year.
