Battery-powered unmanned aerial vehicles (UAVs), also known as drones, have emerged as the primary choice in the UAV market. The UAV Battery Management System (
Unmanned Aerial Vehicles were first introduced almost 40 years ago and their applications have increased and diversified substantially since then, in both commercial and private use.
The UAV Battery Management System (BMS) performs critical functions such as charging and discharging control, state detection, fault diagnosis and warning, data recording and analysis, etc., making it an essential component of UAVs.
Like conventional hybrid-electric vehicles, the hybrid power system combining the ICE and the Lithium battery is the most direct and simplest scheme for achieving both high energy and high power density , . However, the heavy weight and extra volume issues still exist for these ICE/battery hybrid-electric UAVs.
UAV delivery is suitable for emergency supply, remote region logistics, and special logistics. The so-called last-mile delivery is very efficient and convenient. The goods delivery based on UAVs will not be affected by ground transportation and labor shortage.
For instance, with the low-price and heavy-load requirements of plant-protection UAVs, the cheap and high-power Lithium batteries can be used to achieve 10 ∼ 15 min of constant power output. Sometimes, long flight endurance is required for UAVs. In this case, FC/battery hybrid system can be designed to ensure 3 ∼ 5 h of continuous power output.
