More energy. Less space.
Cell to Pack (CTP)
Cell-to-Pack (CTP) design has emerged as a game-changer, offering a wealth of advantages over traditional battery pack designs.
Traditional battery packs comprise cells, modules, and a pack structure.
The cells are first assembled into modules, which are then integrated into the pack structure, along with various mechanical and thermal components. This modular approach has been the industry standard for decades.
The cell-to-pack design, however, eliminates the need for modules by directly integrating cells into the pack structure. In doing so, CTP design simplifies the overall architecture, reduces weight and volume, and improves energy density and thermal management.
At Excess Energy, research and development efforts will focus on refining and optimizing the technology to unlock even greater potential. These efforts include the development of new cell chemistries, improved thermal management systems, and advanced battery management systems (BMS) to further enhance performance, safety, and lifespan.
Key Benefits of Cell-to-Pack Design
- Improved Energy Density
- Reduced Weight and Volume
- Enhanced Thermal Management
- Simplified Manufacturing Process
- Lower Cost
Hybrid Battery Pack -Hybrid Cell to Pack (HyCTP)
Hybrid cell to pack (HyCTP), is a highly innovative project aiming at developing and demonstrating the next-generation, fast charge/discharge and high capacity battery pack for EVs and Urban Air transport applications.
HyCTP's customers are all-electric vehicles, EV Giga-factories, plug-in hybrid electric vehicles (PHEVs), hybrid electric vehicles (HEVs), and EV OEMs that require reliable, higher-performance energy storage to improve their current battery pack at a competitive price.
Excess Energy's HyCTP will bring to the market innovative battery pack technology for the propulsion of EVs, significantly boosting EV adoption with a great benefit for the UK economy and/or national productivity (the UK and EU are still highly dependent on Asian battery production).
HyCTP's overall value propositions include
- Higher power density and discharge rate (Hybrid cell-to-pack)
- ~25% lower cost (or ~25% more capacity)
- Up to 20% less weight & material consumption
- ~3 times more capacity in cold temperatures, at high discharge rates
- 20% increased VCTPR (volumetric cell-to-pack ratio), GCTPR (gravimetric cell-to-pack ratio)
- Safety & reliability
- Security of supply
