Technology
The Carrar battery and cooling units feature an advanced Thermal Management System (TMS) based on two-phase immersion cooling. The TMS leverages the physical phenomenon of latent heat when a liquid turns to gas, using a specially designed nucleation pad to achieve efficient nucleate boiling while minimizing the energy required for vaporization. The result is exceptional heat dissipation with minimal energy consumption within a low-pressure system.
The TMS dynamically adapts heat dissipation to external factors (weather and charging conditions) and internal events (like cell malfunctions) by adjusting internal pressure using a patented software algorithm. This ensures precise temperature control between 25°C and 27°C, preventing damaging heat spikes, extending battery life by up to three times, and boosting overall performance.
Carrar’s TMS enhances vehicle safety by mitigating temperature surges from exothermic events, effectively eliminating thermal runaways and fires. Designed to be compatible with any battery architecture, chemistry, density, and current, Carrar’s TMS is future-ready and supported by multiple patents for this groundbreaking technology.
