Abstract
Described are systems and methods for monitoring and detecting thermal conditions associated with individual cells of a battery. Embodiments of the present disclosure may monitor, detect, and protect against thermal anomalies that may be experienced at individual cells of a battery, without employing the use of thermal sensors (e.g., a thermocouple, thermistor, etc.). The exemplary systems and methods may be implemented in connection with a battery and/or battery pack having cells arranged in a serial configuration that may be employed in an aerial vehicle, such as an unmanned aerial vehicle (UAV). The described systems and methods detect thermal conditions associated with the individual cells of a battery by modeling each cell as an RC circuit and determining the resistance of each cell based on voltage and current measurements. The determined resistance can approximate and/or be representative of the temperature of the respective cell.
