Contemporary Amperex Technology (CATL) chose IAA Transportation 2024 in Hannover to launch the Tectrans battery system.
CATL aspires to reach net zero in battery manufacturing operations by 2025 and across the battery supply chain by 2035. These milestones will help reduce more than 40% of emissions during the lifespan of an electric vehicle. So far CATL says it has achieved carbon neutrality in nine factories.
The CATL Tectrans – Bus Edition is headed to long-distance passenger transport, featuring an energy density of 175Wh/kg. Its “compact design offers long-range capabilities and low energy consumption, enhancing vehicle layout flexibility. The advanced thermal management system maintains optimal performance across various climates, reducing internal temperature disparity by 50% and ensuring longevity even in extreme conditions”, CATL says.
The battery model “employes high-energy, high-press density cathode design at the micro level significantly improving energy density, while a U-shaped seal and a zero-draft angle structural innovation result in a 22% increase in volumetric energy density compared with the previous generation”. In addition, the electrolyte features an additive molecular design and precise film-forming capability.
Two products are available for heavy-duty trucks: one for superfast charging technologies and a second “long life” version.
The Superfast Charging Edition features a 4C peak charging rate, allowing for a 70% charge in just 15 minutes, CATL states. Also, “to tackle the complex temperature difference within the battery pack, an exquisitely crafted flow channel system achieves precise control over various thermal zones, successfully halving the internal temperature disparity”.
The Long Life edition, on the other hand, “sets a new industry benchmark with an exceptional lifespan of up to 15 years or 2.8 million kilometers“.
