Regulatory Trends and Industry Standards (Based on Official Bodies)

Bipolar battery pack thermal management systems are gaining increasing attention from regulatory bodies and industry standard organizations as the adoption of advanced lithium-ion and emerging solid-state battery technologies accelerates. In 2025, regulatory trends are being shaped by the dual imperatives of safety and performance, especially for automotive, stationary storage, and industrial applications.

The SAE International continues to play a pivotal role in developing and updating standards for battery pack design, including those specific to thermal management. The SAE J2929 and J2464 standards, focused on electric vehicle safety and abuse testing, are being revised to address the unique heat dissipation and propagation risks associated with bipolar cell configurations. These updates are expected to influence both OEMs and Tier 1 suppliers, as compliance with SAE standards is often a precondition for widespread market acceptance in North America and other regions.

In parallel, the International Organization for Standardization (ISO) is advancing the ISO 6469 series of standards, which address the safety of rechargeable energy storage systems in road vehicles. Recent draft amendments reflect growing recognition of the specific thermal runaway challenges posed by tightly packed bipolar architectures. ISO’s working groups are collaborating with industry to define more stringent testing protocols for thermal propagation, cooling efficiency, and early fault detection in large-format bipolar packs.

The Institute of Electrical and Electronics Engineers (IEEE) is also active in this space, particularly through the IEEE 1625 and IEEE 1725 standards, which cover battery system reliability and safety for portable and stationary applications. In 2025, amendments are being proposed to explicitly call out best practices for thermal management components, including phase-change materials, liquid cooling plates, and embedded sensors, as they apply to bipolar configurations.

Governmental agencies, such as the National Highway Traffic Safety Administration (NHTSA) in the U.S. and the United Nations Economic Commission for Europe (UNECE), are expected to tighten regulations on thermal event reporting and post-crash thermal management for electric vehicles. UNECE’s Regulation No. 100, which governs the safety of electric powertrains, is undergoing a review to potentially introduce new requirements for thermal propagation mitigation in battery packs, including those using bipolar designs.

Looking ahead, industry-wide harmonization of testing procedures and performance thresholds for thermal management is anticipated, with stakeholders from the automotive and battery sectors contributing to standardization efforts. This is especially relevant given the rapid deployment of bipolar battery packs in commercial vehicles, grid storage, and high-power applications. As regulatory frameworks evolve, compliance with updated standards is expected to become a significant determinant of market access and product liability risk for manufacturers and integrators.

Critical Challenges: Safety, Efficiency, and Scalability

Bipolar battery pack architectures, particularly in lithium-ion and emerging solid-state chemistries, offer significant improvements in energy density and compactness for automotive and stationary storage applications. However, thermal management remains a critical challenge, directly impacting safety, efficiency, and scalability as these packs move towards commercialization in 2025 and beyond.

A primary safety concern is thermal runaway, where uncontrolled cell heating can propagate rapidly due to the high level of integration in bipolar designs. Unlike conventional pack layouts, the stacked configuration in bipolar packs restricts the space available for traditional cooling channels and thermal barriers. Manufacturers such as Panasonic Corporation and Toshiba Corporation, both actively developing advanced battery modules, are investing in new materials and cooling architectures. Innovations include integrated phase change materials, thin liquid cooling plates, and highly thermally conductive substrates to dissipate localized heat spikes. These approaches are under evaluation to ensure that the compact form factor of bipolar packs does not compromise cell-level safety.

Efficiency is also closely tied to thermal regulation. Uneven temperature distribution within a bipolar stack can accelerate cell degradation and reduce cycle life, undermining the cost benefits of higher energy density. Companies such as Nissan Motor Corporation, which has piloted bipolar lithium-ion batteries for commercial vehicles, are publicly emphasizing the need for precise thermal management to ensure uniform temperature across all layers. Solutions being trialed in 2025 include distributed temperature sensors embedded within the stack and active feedback control systems to dynamically adjust coolant flow or fan speed.

Scalability presents perhaps the most significant barrier for widespread adoption. As manufacturers like Nemaska Lithium and Sony Group Corporation explore industrial-scale bipolar battery production, integrating robust yet cost-effective thermal management systems becomes essential. The challenge is compounded for larger packs intended for grid-scale or heavy-duty transport, where thermal gradients can be more pronounced. Industry collaboration is underway, with battery consortia and manufacturers aiming to standardize thermal interface materials and modular cooling solutions suitable for high-throughput manufacturing.

Looking forward, regulatory bodies such as the SAE International are expected to refine guidelines on thermal management for next-generation battery packs within the next few years, potentially making advanced thermal solutions a prerequisite for certification in automotive and stationary markets. As the technology matures, resolving these thermal management challenges will be crucial to unlocking the full commercial potential of bipolar battery systems.

Emerging Applications: Automotive, Energy Storage, and Beyond

Bipolar battery pack architectures are drawing increasing interest for high-power applications, particularly in automotive and stationary energy storage, due to their potential for superior energy density, compact design, and simplified assembly. However, these configurations pose unique challenges for thermal management. As of 2025, advancements in thermal management systems tailored for bipolar battery packs are critical for unlocking their performance advantages and ensuring safety in real-world deployments.

In the automotive sector, next-generation electric vehicles (EVs) are evaluating bipolar lithium-ion and bipolar nickel-metal hydride (NiMH) packs for their ability to reduce electrical resistance and improve volumetric efficiency. Yet, the tightly stacked cell design of bipolar packs increases the risk of non-uniform temperature distribution, hotspot formation, and thermal runaway propagation. Leading automotive battery suppliers such as Panasonic and Toshiba are actively developing advanced cooling strategies, including integrated liquid-cooling channels, phase change materials (PCMs), and thermal interface materials (TIMs) to address these risks. For example, liquid-cooled plates integrated between cells or modules can extract heat more efficiently than conventional air cooling, which is less effective in the dense environment of bipolar stacks.

In the stationary energy storage market, where modularity and scalability are essential, companies like Honda (with its experience in large-format NiMH bipolar packs for hybrid energy systems) are exploring embedded micro-channel cooling and active temperature monitoring to ensure pack longevity and mitigate thermal gradients. These systems are particularly relevant as grid-scale installations require both high reliability and predictable thermal performance under fluctuating load cycles.

Thermal management for bipolar battery packs is also being influenced by emerging materials and digital technologies. Manufacturers are experimenting with thermally conductive adhesives, ceramics, and novel polymers to enhance heat dissipation without sacrificing cell-to-cell electrical connectivity. Simultaneously, predictive diagnostics powered by embedded sensors and cloud-based analytics are gaining traction, allowing real-time detection of thermal anomalies and pre-emptive intervention, especially in mission-critical applications.

Looking ahead, the rapid evolution of bipolar battery architectures is pushing suppliers and OEMs to co-develop bespoke thermal management solutions. The next few years will likely see greater adoption of hybrid cooling approaches—combining liquid, air, and PCM—alongside tighter integration of pack-level intelligence for dynamic thermal regulation.
