Challenges: Data Accuracy, Standardization, and Lifecycle Management

Lithium-ion battery health diagnostics are increasingly critical as electric vehicles (EVs), grid storage, and portable electronics proliferate. However, the sector faces persistent challenges in data accuracy, standardization, and lifecycle management, which are expected to shape industry priorities through 2025 and beyond.

A primary challenge is the accuracy of battery health data. Battery management systems (BMS) rely on a combination of voltage, current, temperature, and sometimes impedance measurements to estimate state-of-health (SoH) and state-of-charge (SoC). However, these estimations are often affected by sensor drift, environmental conditions, and cell-to-cell variability. Leading manufacturers such as Panasonic and LG Energy Solution are investing in advanced algorithms and sensor technologies to improve diagnostic precision, but real-world accuracy remains a concern, especially as batteries age and degrade in unpredictable ways.

Standardization is another major hurdle. The lack of universally accepted protocols for battery health diagnostics complicates interoperability and data sharing across the value chain. Organizations like SAE International and IEEE are working on standards for battery testing and data formats, but adoption is uneven and often lags behind technological advances. This fragmentation makes it difficult for automakers, battery suppliers, and recyclers to exchange reliable health data, impeding efforts to establish robust second-life and recycling markets.

Lifecycle management is also under scrutiny. As batteries move from first use in vehicles to potential second-life applications (such as stationary storage), accurate health diagnostics are essential for determining residual value and safety. Companies like Tesla and Contemporary Amperex Technology Co., Limited (CATL) are developing proprietary diagnostic tools to track battery health throughout the lifecycle, but the lack of standardized data formats and diagnostic criteria complicates cross-industry collaboration. Furthermore, regulatory bodies in Europe and Asia are beginning to require more transparent battery health reporting, adding urgency to the need for harmonized approaches.

Looking ahead to 2025 and the following years, the industry is expected to intensify efforts to address these challenges. Initiatives to improve sensor accuracy, develop open data standards, and implement digital battery passports are gaining momentum. However, progress will depend on collaboration among manufacturers, standards organizations, and regulators. Without significant advances in data accuracy, standardization, and lifecycle management, the full potential of lithium-ion battery health diagnostics—and by extension, the circular battery economy—will remain constrained.
