About the Cell

The Amprius SA02 cell is designed in a pouch form factor, featuring a nominal capacity of 38.5 Wh and 11.0 Ah. This cell boasts a volumetric energy density of 740 Wh/l, which is in the top-quartile compared to the database median of 542 Wh/l, making it an excellent choice for applications requiring high energy density. Additionally, the gravimetric energy density stands at 340 Wh/kg, which is around the median of 210 Wh/kg. The cell's maximum continuous discharge rate of 33.0 A places it in the top-quartile against the median of 30 A, ensuring robust performance under demanding conditions. Furthermore, the volumetric power density of 2,219 W/l is around the median of 2,029 W/l, indicating strong power delivery capabilities. These specifications make the SA02 cell particularly suitable for UAV applications where weight and efficiency are critical.

Application Challenges

In the EVTOL application, maximising flight time is paramount. The ability to optimise cell selection, duty cycle, and flight speed directly impacts the operational efficiency of UAVs. High energy density is essential for extending flight duration, while effective thermal management is crucial to prevent overheating during prolonged use. The Amprius SA02 cell's specifications, including its high volumetric energy density and robust discharge capabilities, address these challenges effectively. By selecting the right battery cells, UAV manufacturers can enhance mission endurance and ensure reliable performance in various environmental conditions, including extreme temperatures.

Why this Cell

The Amprius SA02 cell is an ideal choice for EVTOL applications aiming to maximise flight time. With a maximum continuous discharge of 33.0 A, it is in the top-quartile compared to the median of 30 A, ensuring that it can handle high power demands during critical flight phases. Additionally, its volumetric energy density of 740 Wh/l is significantly higher than the median of 542 Wh/l, providing more energy in a compact form factor. This allows for longer missions without the need for additional weight, directly addressing the challenge of battery weight versus flight time in UAV design. The combination of these metrics makes the SA02 cell a leading option for UAV battery optimisation.

How Model-Based Design Helps

Simulation and model-based design play a crucial role in selecting the right battery cells for UAV applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the Amprius SA02 cell will perform under various conditions. This approach allows for the identification of optimal duty cycles and flight speeds, ensuring that the cell operates within safe thermal limits while delivering the required power. For instance, by simulating different flight scenarios, designers can assess the impact of temperature and state of charge (SoC) on performance, enabling informed decisions that enhance mission reliability. This predictive capability is essential for UAV operators who need to ensure that their drones can complete missions without mid-air failures, especially in challenging environments.
