Building Safer Battery Packs

Battery safety at the pack level is crucial as it serves as the final line of defense against potential failures that could compromise the entire system. While individual cells are the building blocks of a battery, the pack level involves the integration of these cells into a unified, functioning unit that powers the vehicle. This is where critical safety measures, such as thermal management systems, protective casing, and fail-safes, are implemented to ensure that any issues within a single cell do not escalate into a more significant hazard. Effective safety management at the pack level not only prevents catastrophic events like fires or explosions but also enhances the overall reliability and longevity of the battery. Ensuring robust safety protocols at this stage is essential for maintaining consumer trust and advancing the widespread adoption of electric vehicles.

The safety benefits of Electra’s Battery Digital Twin stem from its ability to deliver detailed analysis of battery pack laboratory tests and develop highly representative machine learning (ML) models.

The ML models generated by the Battery Digital Twin also enable predictive maintenance and enhanced monitoring, ensuring that batteries operate within safe parameters throughout their lifecycle, ultimately reducing the likelihood of safety incidents and improving overall reliability.

The Complexity of Battery Failures

The causes of battery failure are multifaceted, often involving a combination of factors that can be difficult to detect and manage. One of the most common and dangerous issues is lithium plating. This phenomenon occurs when metallic lithium deposits form around the anode, particularly during fast charging at low temperatures. Over time, these deposits can lead to the growth of dendrites—needle-like structures capable of piercing the separator between the anode and cathode. This can result in a short circuit, leading to rapid self-discharge and, in severe cases, thermal runaway—a chain reaction that can be extremely difficult to stop once initiated and extremely dangerous as well.

Our software empowers fleet managers and EV drivers alike with complete visibility into the real-time status of their electric vehicles by estimating the State of Charge (SoC), State of Health (SoH), and power for batteries.
