Thermal Management System for EV Batteries
Carrar provides cutting-edge thermal management systems (TMS) for electric vehicles based on innovative two-phase immersion technology that maintains optimal battery temperature in all weather conditions and through ultrafast charging.
By preventing heat spikes caused by charging, acceleration, and extreme weather, Carrar triples battery lifetime, lowering the total cost of ownership of electric vehicles. Carrar enhances the safety of electric vehicles by reducing thermal propagation and battery fires.
By extending the battery lifetime, Carrar reduces the environmental impact of EV batteries and contributes to every stage of the battery circular battery economy (read more here).
Addressing the Main Challenges of EV Batteries
Lifespan
Battery Modules for Electric Vehicles
Carrar develops and produces battery modules for electric vehicles with an internal thermal management system (TMS) based on two-phase immersion cooling.
Our modules provide top-of-the-line battery performance, actively maintaining an optimal temperature range in cold or hot weather and during ultrafast charging and discharging, increasing battery longevity and performance.
Our modules are lighter and provide a superior power-to-weight ratio to current modules. The modules are also safer to use, as the thermal management system maintains uniform temperature throughout the battery cell, significantly reducing incidents of thermal runaway and fire.
We produce cylindrical, prismatic, and pouch-type modules that fit all types of electric vehicles, from three-wheelers to heavy-duty trucks.
Powertrain and computer cooling units
Vapor out
Liquid in
Carrar provides a two-phase direct-contact enhanced evaporation technology (DCEC) for highly efficient cooling of the powertrain and in-vehicle computing units.
A direct on-chip cooling solution maximizes the power and performance of high-density, small form-factor processors.
A custom-designed evaporation unit cools both high and low heat-flux components with different heat dissipation requirements, including the power-electronic system (converters, inverters, control circuits, and onboard chargers, such as MOSFET and IGBT).

Technology
Carrar developed a patented two-phase thermal management solution suitable for all EV components, including batteries, the powertrain, and In-Vehicle computers.
Carrar leverages the physical phenomenon of latent heat when a liquid turns into a gas, combined with a unique technology that reduces the boiling incipience superheat. As a result, our solution achieves high heat dissipation and fast cooling, using very little energy and within a low-pressure system.
Our solution dynamically adjusts heat dissipation to external heat conditions, assuring a constant battery temperature regardless of battery charging, car acceleration, or climate conditions.
The Carrar heat dissipation mechanism extends battery life and lowers the risk of thermal runaway and propagation – the major safety concern of electric vehicles.
Carrar works with materials that support environmental and sustainability regulations and with every form of battery and electric vehicle. Carrar holds several patents for this technology.
