CATL Unveils Revolutionary TECTRANS II Battery at IAA Transportation 2026

Contemporary Amperex Technology Co., Limited (CATL) has recently debuted its groundbreaking TECTRANS II battery solution during the IAA Transportation 2026 event held in Hannover, Germany. This innovative platform marks a significant step forward in the push for global electrification of commercial vehicles.

The Driving Force Behind TECTRANS II

Akin Li, the Executive President of CATL's Overseas Business, emphasized the importance of this development, stating, "The electrification of commercial vehicles represents the third wave of the global energy transition." The new TECTRANS II aims to partner with various global partners across different sectors—products, energy, services, and ecosystems—to capitalize on this momentum.

Key Features of TECTRANS II

This next-generation battery solution offers a versatile modular platform designed specifically for commercial vehicle electrification. Here are some of its standout features:

• - Adaptability for Diverse Vehicle Needs: The TECTRANS II is suitable for a wide range of applications, accommodating various operational requirements for commercial vehicles.
• - Multi-scenario Platform: By configuring different quantities of standard battery packs, this solution can meet diverse energy capacity and payload requirements, delivering a maximum range of up to 1,000 kilometers on a single charge.
• - Flexible Technology Approaches: The platform supports both electric axle architectures and centralized drive systems, enabling a flexible choice between conventional charging and battery swapping.
• - Unique Configuration for Future Compatibility: The standardization of external dimensions, electrical interfaces, and communication protocols allows for the evolution of battery technologies and pack designs, ensuring that both new and existing vehicle models can benefit from future updates without significant overhauls.

Economic Lifespan and ROI

Beyond its technical specifications, the TECTRANS II is engineered to maximize economic benefits throughout a vehicle's lifecycle. These include:

• - Quicker ROI: By eliminating the need for model-specific battery systems, OEMs can minimize development costs, shorten time-to-market, and reduce investment risks during early phases.
• - Higher Operational Profitability: The TECTRANS II enhances fleet profitability through several means:

- Increased Energy Density: With a gravimetric energy density of 170 Wh/kg, approximately 13% above the industry average, the battery allows vehicles to carry about 0.6 tons more payload without additional battery capacity.
- Extended Range and Faster Charging: Capable of reaching 80% charge in just 25 minutes with megawatt-level fast charging, the TECTRANS II minimizes downtime on long-haul routes.
- Enhanced Energy Efficiency: It features a pioneering low-impedance design with full-tab technology, providing an impressive round-trip efficiency (RTE) of 96%, thus reducing losses during charging and offering more usable energy for daily operations.
- Robust Residual Value: Designed for a lifespan of 12 years and 1.5 million kilometers, TECTRANS II maintains 70% capacity retention, ensuring higher residual asset value for fleets.

Reliability and Safety Assured

The TECTRANS II platform is specially engineered for durability within real-world commercial operations.

• - Sturdy Physical Protection: It incorporates features such as a hot-formed steel top cover that withstands 10,000 footsteps from an adult weighing 180 kg without deformation and an ultra-resistant lower plate that absorbs impacts of up to 1,000 Joules, safeguarding the battery package from road accidents.
• - High-Strength Housing: Built from extruded aluminum with crush-resistant ridges, it offers lateral crush resistance up to 250 kN.
• - Corrosion Resistance & Easy Maintenance: With a corrosion resistance guarantee of 15 years, the design ensures functionality in coastal and frigid regions, along with features that maintain safety during maintenance procedures.
• - System Redundancy: The system architecture features independent multi-branch BMS controls, allowing the isolation of faulty branches while maintaining power supply through others.
• - Cybersecurity Measures: CATL ensures robust multi-layer protections encompassing chip hardware, software, and vehicle systems, complying with international information security standards throughout development processes.

A Commitment to Sustainability and Collaboration

During the IAA Transportation 2026, CATL also announced a memorandum of understanding (MoU) with DHL Group to develop sustainable freight transport corridors in Europe. This mutual commitment builds on their previous agreement from September 2024 and aims to harness DHL's logistics network and operational expertise alongside CATL's battery technology and electrification ecosystem.

Zhu Lingbo, CTO of CATL's Global Business Unit, remarked, "The electrification of commercial vehicles will unfold over the next decade. With our deep technological expertise and long-term commitment, CATL is poised to become the most reliable partner for clients worldwide in the quest for global freight transport electrification."

With the launch of TECTRANS II, CATL cements its position as a leader in the transition to electric commercial vehicles, setting a new standard for safety, power, and efficiency in the industry.
