The cell's gravimetric energy density is 200 Wh/kg, which is around the median of 210 Wh/kg. It also boasts a volumetric power density of 4208 W/l, which is among the highest in the database, and a gravimetric power density of 1600 W/kg, which is +113% vs the median of 750 W/kg. These specifications make the 25R an excellent choice for drone applications, particularly where space and weight are critical factors.
Application Challenges
In the context of drones, mission feasibility assessment involves determining the viability of various missions based on energy requirements and environmental conditions. The Samsung 25R cell's high energy density is crucial for extending flight times, allowing drones to cover greater distances without the need for frequent recharges. Additionally, the ability to handle high discharge rates is essential for missions requiring rapid bursts of power, such as takeoff or sudden manoeuvres. Accurate predictions of battery state of charge (SoC) are vital to prevent mid-air failures, especially in extreme environments where temperature fluctuations can impact performance. The 25R's specifications support these needs, making it a reliable choice for UAV operators.
Why this Cell
The Samsung 25R cell is particularly suited for drone applications due to its impressive specifications. With a maximum continuous discharge of 20.0 A, it is ideal for high-demand scenarios, ensuring that drones can perform optimally during critical phases of flight. The cell's volumetric energy density of 526 Wh/l places it in the top-quartile compared to the database median, allowing for more compact battery designs without sacrificing performance. This is particularly important for UAVs that require lightweight battery packs to maximise flight endurance. Furthermore, the gravimetric power density of 1600 W/kg supports rapid energy delivery, essential for maintaining drone powertrain efficiency during dynamic operations.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the Samsung 25R cell for drone applications. By modelling load profiles, engineers can predict how the cell will behave under various conditions, including thermal rise and voltage sag. This allows for accurate assessments of usable energy across different mission profiles. For instance, simulations can help determine the optimal cruise speed for drones, balancing energy consumption and flight range. Additionally, thermal management simulations ensure that the cell operates within safe temperature limits, preventing overheating and extending battery life. Overall, these modelling techniques enable informed decision-making, ensuring that the right cell is selected for specific mission requirements.
