Figure 1: Drone in medical service

A drone carrying critical blood samples took off from city of Meerut and landed in Delhi, India after a successful one hour flight. Drone had to stop midway for a scheduled battery swap. But by road, same journey would have taken more than two hours. It’s a game changer for India’s medical industry and it can possibly make healthcare accessible to remote regions. This was just one of 1000 test flights that company, Skye Air Mobility have tested since November last year and company claims they have delivered more than 3,500 kg of mixed payload - ranging from e-commerce deliveries to blood samples. This is just one example of how drones are being used in critical lifesaving operations. Identifying accurate state of health (SoH) of a battery is more crucial than ever. 

Figure 2: Energy allocation of a battery

RUBY system will be very useful for drone battery fleet management as Remaining Useful Battery Yield; RUBY assures a fixed amount of reserve charge by training based on usage. If, for example, the energy demand increases over time, the Intelligent Target Selector moves the diagnostic charger to a higher pass/fail threshold to maintain the required reserve charge. This will prompt more marginal batteries to fail. If, however, energy demand decreases, the Target Selector relaxes the setting and marginal batteries
