Cell-to-chassis battery technology


Technology Description

Cell-to-Chassis (CTC) technology integrates the battery cell with the chassis and then integrates the motor, electronic control, and vehicle high voltage such as DC/DC, OBC, etc, and an intelligent power domain controller optimises power distribution and reduces energy consumption. It could lead to a significant increase of energy density by removing some components of the standard battery packs, but it bring safety and re-usability (second life) challenges that need to be adressed.
CATL is accelerating the research and development of CTC, and announced that it plans to launch its own CTC solution around 2025.

Relevance for Net Zero

This technology would enable new energy vehicles to directly compete with fuel vehicles in terms of cost, with larger riding space and chassis passability getting better.
