Frequently Asked Questions
What coolant is recommended for EV battery liquid cooling systems?
The industry standard is 50/50 ethylene glycol-water (WEG) mixture, providing freeze protection to -37C and boil protection to 106C. Some OEMs use dielectric fluids for direct immersion cooling. Coolant selection must account for material compatibility with aluminum cold plates, seals, and hose materials over 15-year vehicle service life.
How do you achieve uniform cell temperature in a large EV battery pack?
Uniform temperature distribution requires optimized coolant flow path design (parallel channels with balanced manifolds), adequate flow rate (typically 8-15 LPM for passenger EVs), proper thermal interface material (TIM) between cells and cooling plate, and system-level controls that modulate pump speed and chiller capacity based on real-time cell temperature data.
Does ToneCooling provide complete battery thermal management solutions?
ToneCooling provides battery cooling plates, thermal interface materials integration, and thermal simulation services. Our engineering team supports OEMs from concept design through CFD-validated thermal analysis, prototype delivery, DV/PV testing, and mass production for prismatic, pouch, and cylindrical cell formats.
