Thermal Management for EV Batteries
Carrar provides a thermal management solution (TMS) for EV batteries, based on a patented two-phase immersion technology that normalizes battery temperature regardless of heat fluctuations caused by very hot or cold climates, ultrafast charging, and car acceleration.
By maintaining optimal battery temperature, Carrar increases driving range, extends battery lifetime (up to twice as long), enhances the safety of electric vehicles, and lowers their total cost of ownership. Carrar contributes to sustainability by supporting worldwide adoption of EVs and by reducing the environmental impact of EV batteries.
Addressing the Main Challenges of EV Batteries
Lifespan
MODULES FOR EV BATTERIES
Carrar develops and produces high-density modules for EV batteries with an internal thermal management system (TMS) based on our two-phase immersion cooling technology. Our modules are built to provide top-of-the-line battery performance, actively maintaining an optimal temperature range in very cold or hot weather and during ultrafast charging and discharging, achieving many charging and discharging cycles and increasing battery longevity.
We produce cylindrical, prismatic, and pouch-type modules that fit various electric vehicles. Ultra-high cycle life Ultra high energy system and high energy density.
For the Powertrain and In-Vehicle Computing

Carrar provides a two-phase direct-contact enhanced evaporation technology for highly efficient cooling of the powertrain and In-Vehicle computing components.
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 (converter, inverter, control circuits and onboard charger, such as MOSFET and IGBT).

Technology
Carrar developed a patented two-phase thermal management solution suitable for all EV components including EV batteries, the powertrain, and In-Vehicle computing components.
Carrar leverages the physical phenomenon of latent heat when a liquid turns into a gas, using our unique technology to reduce the boiling incipience superheat. As a result, our solution achieves high heat dissipation and fast cooling with low-energy consumption and within a low-pressure system.
Our solution adjusts the heat dissipation dynamically to external heat conditions, assuring a constant battery temperature regardless of charging, 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.
