About the Cell
The EVE Energy 50PL cell features a cylindrical 21700 form factor, providing a nominal capacity of 18.0 Wh (5.0 Ah). With a volumetric energy density of 724 Wh/l, it ranks in the top-quartile compared to the database median of 542 Wh/l, making it suitable for applications requiring high energy storage in limited space. The cell also boasts a maximum continuous discharge of 80 A, which is significantly above the median of 30 A, ensuring it can handle demanding power requirements. Additionally, its gravimetric energy density of 250 Wh/kg positions it well within the competitive landscape, offering a balance of weight and energy efficiency. This combination of features makes the 50PL an excellent choice for drone applications, where performance and efficiency are paramount.
Application Challenges
In the realm of drones, maximising flight time is crucial for operational efficiency. The EVE Energy 50PL cell addresses this challenge by providing high energy density and robust discharge capabilities. In practical terms, the ability to optimise cell selection and duty cycle directly impacts the duration a drone can remain airborne. For instance, a higher nominal capacity allows for longer missions without the need for frequent recharging, which is essential for applications such as industrial inspections or emergency response. Furthermore, the lightweight design of the 50PL cell contributes to overall drone efficiency, enabling it to carry additional payloads or operate at higher speeds without compromising flight time.
Why this Cell
The EVE Energy 50PL cell is specifically designed to meet the demands of drone applications, particularly in maximising flight time. With a maximum continuous discharge of 80 A, it is positioned in the top-quartile compared to the median of 30 A, allowing for high power output during critical phases of flight. Its volumetric energy density of 724 Wh/l, which is +33% vs the database median, ensures that drones can carry more energy in a compact form factor, thereby extending operational range. Additionally, the cell's gravimetric power density of 4000 W/kg supports rapid energy delivery, making it ideal for dynamic flight scenarios where quick acceleration is necessary. These metrics highlight the 50PL's suitability for applications that require both endurance and performance.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the EVE Energy 50PL cell for drone applications. By modelling load profiles, engineers can predict how the cell will behave under various operational conditions, including thermal rise and voltage sag. This predictive capability allows for the selection of the most suitable cell for specific missions, ensuring that drones can operate efficiently without risking battery failure. For example, simulations can help determine the optimal duty cycle and flight speed, maximising usable energy while preventing overheating. This approach not only enhances the reliability of drone operations but also reduces the need for costly trial-and-error testing, ultimately leading to more effective mission planning and execution.
