Carrar builds two-phase immersion system architecture that unlocks the full potential of the battery pack — more usable energy in less space, charged faster, for longer, at a lower LCOS.
Every battery pack today is designed around compromise: cells are derated, oversized and spaced apart to stay safe, so customers pay for capacity they can never use. Carrar removes that compromise. Our two-phase immersion system architecture lets the same cells deliver more usable energy in less space, charge faster, last longer and resist propagation by design, materially cutting levelized cost of storage. Unlike incremental pack optimization, Carrar changes the architecture itself, and it integrates with standard cells and existing production lines. Validated with leading automotive and energy partners, Carrar turns stranded battery capacity into revenue.
