At a Glance: Carrar
Growing EV Adoption & Profits with Better Thermal Management
Four significant obstacles hinder the worldwide deployment of electric vehicles: a long charging time; short battery lifetime; the high total cost of owning an EV; and safety – situations of thermal runaways and fires that are hard to contain and extinguish.
All those problems stem from the current limitations of electric vehicle batteries or the inability to control their temperature effectively.
Current thermal management systems (TMS) cannot keep the temperature of EV batteries consistently at the required range (normally 10⁰C above or below 25⁰).
As a result, the battery degrades over time, resulting in sub-optimal function and a shorter lifetime.
Carrar is a novel thermal management solution based on a patented immersion two-phase technology, which provides a complete thermal management solution for electric vehicle components, including batteries, the powertrain, and in-vehicle computing components.
Innovative Thermal Management Technology
Carrar leverages the physical phenomenon of Latent heat when a liquid turns into a gas (similar to air conditioners). As a result, Carrar uniquely achieves boiling incipience superheat using very little energy and within a low-pressure system (of <2 bar) and holds several patents for this technology.
Carrar offers a superb temperature control system that dissipates heat more than twice as fast as current best in class solutions; the system is simpler (with fewer components) and weighs less.
Carrar adjusts heat dissipation (i.e., the boiling level) dynamically, assuring a constant battery temperature regardless of ultrafast charging and ambient temperature (climate).
In addition, Carrar keeps temperatures stable at the cell level – and within the cell (the temperature at the core equals the circumference). By keeping cell temperature stable, Carrar significantly lowers the chance of thermal runaway and propagation – the most significant safety concerns of electric vehicles.
Carrar works with variety of engineered liquids that support environmental and sustainability regulations and supports every form of battery and electric vehicle.
