Efficient thermal management Actively cooled High-voltage cables from Coroflex – lightweight, flexible, high-performance
Quality from experience Liquid-cooled High-voltage cables for a wide range of applications
Whether in passenger cars, commercial vehicles, buses, construction machinery, or agricultural applications – our cooled High-voltage cables ensure reliable power transmission even in tight spaces and under heavy loads.
With our many years of experience in series production for leading automotive manufacturers, Coroflex stands for proven quality and engineering expertise down to the smallest detail. Our cooled HV cables, for example, are up to 60 % lighter and about one-third smaller in diameter than conventional systems. Thanks to these advantages, our solutions save material, energy, and costs, and can be integrated into complex vehicle architectures in a particularly economical and space-saving way.
At a glance Your benefits with our actively cooled High-voltage cables
- Greater range and efficiency:
Weight reduction lowers energy consumption and increases overall efficiency – delivering more range with the same battery capacity. - Shorter charging times:
Active cooling technology reduces conductor temperatures and prevents thermally induced charging limitations. Regardless of ambient temperatures, active cooling enhances the performance of HV cable systems by shortening charging times. - More design freedom in the vehicle:
Smaller diameters and high flexibility save space and simplify integration into compact vehicle architectures. - Tailored to every requirement:
The modular technology allows for shielded or unshielded designs as well as copper or aluminum conductors – with sizes ranging from 35 to 200 mm² for maximum design freedom. - Economical and cost-efficient:
Saving conductor material reduces system costs and contributes to the overall cost-effectiveness of the vehicle. - Reliable and protected:
Optimized thermal management extends component lifespan; optionally, Coroflex ProTect cables provide additional protection for use in particularly harsh environments..

Requirements in detail Complex challenges, concrete solutions
Thermal management as the key to efficiency
The higher the electrical power, the more complex the interaction between current, temperature, and available space becomes. In modern electric vehicles, our High-voltage cables reliably transmit high continuous currents in tight spaces, under varying ambient temperatures, and close to sensitive electronics. The combination of thermal stability, mechanical robustness, and precise system integration determines the overall system efficiency.
Cooling circuit and temperature resistance
Our cooled High-voltage cables dissipate heat in a controlled manner and maintain constant operating temperatures – even at high current densities or in tight spaces. The cooling medium typically consists of a water-glycol mixture, operated at high pressure in the cooling circuit. It continuously flows through the cable, enabling effective heat removal even at ambient temperatures between - 40 °C and + 85 °C.
Our HV cables are pressure-resistant, vibration-resistant, and resistant to common cooling media – ensuring system performance even under demanding conditions.
Material selection and variety of options
Choosing copper or aluminum as the conductor material allows for an optimal balance between conductivity, weight, and cost. Shielded and unshielded variants meet a wide range of EMC requirements. Thanks to the modular design and a range of cross-sections from 35 to 200 mm², the cables can be precisely adapted to each vehicle architecture – from passenger cars and commercial vehicles to maritime applications and heavy construction machinery.
Practical advantages through active cooling
Active cooling allows for a significant reduction in conductor cross-section: for example, a 35 mm² cooled cable is directly comparable to a 170 mm² uncooled cable. Coroflex’s active cooling technology reduces weight, saves material, and creates room for more compact designs.
For particularly demanding environments, our optional ProTect protection system is available. The cables, additionally equipped with Coroplast wire harness tape and delivered as a ready-to-install complete system directly on the spool, offer thermal advantages compared to other protection systems.
