Application Challenges
In the EVTOL sector, fast charging of batteries is critical to ensure operational efficiency and safety. The challenge lies in charging the battery quickly without overheating the cells or causing lithium plating, which can degrade the battery or lead to catastrophic failures. Effective thermal management is essential to prevent overheating, especially during rapid charge cycles. The Tenpower 40XG cell's high maximum continuous charge rate of 16 A (4 C) facilitates quick charging while maintaining thermal stability. This capability is vital for applications requiring quick turnaround times, such as drone deliveries or emergency response missions. The ability to manage heat generation during charging is paramount, as excessive heat can lead to reduced battery life and performance. Therefore, selecting the right cell, like the 40XG, is crucial for achieving optimal performance in fast-charging scenarios.

How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the Tenpower 40XG cell for fast charging applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various charging conditions. This includes assessing heat generation during rapid charge cycles and understanding voltage sag under load. Such simulations allow for the identification of optimal charging strategies that maximise efficiency while minimising the risk of overheating. Furthermore, by using cell-specific data, engineers can simulate different scenarios, such as low state of charge (SoC) and varying temperatures, to ensure that the UAV can reliably complete missions without mid-air failures. This predictive capability is essential for mission-critical applications, where reliability and performance are paramount.
