On September 15, 2026, during the IAA Transportation event held in Hannover, Germany, Contemporary Amperex Technology Co., Limited (CATL) showcased its latest innovation, the TECTRANS II battery solution, designed specifically for commercial vehicles. This new platform aims to accelerate the global electrification of commercial transport, marking a significant step in the transition towards sustainable energy sources.

The Vision Behind TECTRANS II

Akin Li, the Executive President of CATL Overseas Business, emphasized that the electrification of commercial vehicles represents the third major phase of global energy transition. With the TECTRANS II, CATL is poised to collaborate with partners around the world, leveraging advancements in products, energy solutions, services, and ecosystem development to harness opportunities presented by this emerging wave of electrification.

Key Features of TECTRANS II

The TECTRANS II is a modular battery platform tailored for various commercial applications, designed with adaptability to meet diverse operational requirements. Here are some of the standout features:

• - Modular Design:The platform allows configurations of different standardized battery block counts, catering to varying energy capacity and payload needs while supporting a range of up to 1,000 kilometers on a single charge.
• - Flexible Technology Paths:It is engineered to integrate with both electric axle architectures and central transmission systems, facilitating seamless battery charging and replacement transitions.
• - Future-Proof Compatibility: By standardizing external dimensions, electrical interfaces, and communication protocols, TECTRANS II ensures ongoing compatibility with evolving battery technologies and block designs, enabling both new and existing vehicle models to benefit from future upgrades without major structural modifications.
• - Research and Development Efficiency: The platform significantly reduces development cycles for manufacturers by approximately 50%, and R&D costs by up to 60-70%, expediting the launch of new models while decreasing adaptation expenses.

Economic Advantages

In addition to operational efficiency, TECTRANS II enhances the economic viability across the vehicle's lifecycle:

• - Quick Return on Investment: The modular formation minimizes the need for bespoke battery systems for each vehicle model, thus lowering development costs and shortening launch timelines, effectively mitigating early investment risks.
• - Improved Operational Returns: This battery solution boosts fleet economics through several aspects:

- Higher Energy Density: With a gravimetric energy density of 170 Wh/kg, which exceeds the industry average by roughly 13%, TECTRANS II allows vehicles to carry an additional payload of about 0.6 tons, optimized for energy usage.
- Extended Range and Rapid Charging: The maximum configuration provides an impressive range of up to 1,000 km, and utilizes fast charging technology to achieve 80% charge in just 25 minutes, minimizing downtime during long hauls.
- Increased Energy Efficiency: The innovative "full-tab" low impedance design achieves a system round-trip efficiency of 96%, thereby reducing charge losses and enhancing energy availability for daily operations.

• - Higher Residual Value: The TECTRANS II battery is built to last for 12 years and up to 1.5 million kilometers while retaining 70% of its capacity, significantly bolstering the asset value of commercial fleets.

Safety and Durability

Safety is paramount in the design of TECTRANS II, tailored to meet the demanding conditions of commercial usage:

• - Robust Physical Protection: The hot-formed steel upper cover withstands deforming impact from repeated usage, while the ultra-durable lower plate can endure shocks of up to 1,000J, protecting the battery packs from road impacts.
• - Corrosion Resistance: Designed for a 15-year lifespan, the battery remains operational even in coastal regions and harsh cold environments.
• - Maintenance Simplicity: Ensures safety with IPXXB protection during connector handling, enhancing high-voltage safety during maintenance tasks.

Redundancy Built-In

TECTRANS II incorporates advanced redundancies, allowing continued operation even when components fail:

• - Branch Isolation: The independent multi-branch BMS enables isolation by distinguishing malfunctioning branches, ensuring continued electricity supply from other branches, thus maintaining operational integrity.
• - Anomaly Detection: The proprietary fault isolation technology accurately discerns whether issues originate from the battery or other vehicle components, speeding up diagnostics and repairs.
• - Comprehensive Cybersecurity: Security measures encompass multilayer protection across hardware, software, and vehicle systems, adhering to international information security standards throughout the development lifecycle.

In summary, TECTRANS II exemplifies CATL's steadfast commitment to continuous innovation and product quality. Coupled with rigorous real-world operational testing, including comprehensive vehicle torsion tests and external fire resistance evaluations, the platform is designed to ensure safety, reliability, and longevity in the challenging environments faced by commercial vehicles.

A Collaborative Future

Additionally, during the event, CATL secured a memorandum of understanding with DHL Group aimed at developing eco-friendly freight corridors across Europe. Building on a previous agreement from September 2024, this partnership combines DHL's logistics expertise and actual transportation needs with CATL’s advanced battery technology and electrification ecosystem. They seek to produce specific-purpose electric vehicles and commence pilot projects together.

"The electrification of commercial vehicles will evolve over the next decade," stated Zhu Lingbo, CTO of CATL’s Global Business Unit. “With our deep technological expertise and long-term commitment, CATL is positioned to be the most reliable partner for our clients in the global freight transport electrification journey.”
