Battery Electric Vehicles (BEVs)
Advanced battery cooling solutions for electric vehicles, from conventional Internal Combustion Engine (ICE) coolants with extensive OEM approvals to our low e-conductive coolant range for markets where enhanced electrical safety or compliance with GB 29743 standards is a key requirement.
Why Battery Cooling Matters in BEVs
Battery Electric Vehicles (BEVs) are powered entirely by electric energy stored in high-voltage battery packs. These batteries, along with other critical components such as the electric motor, power electronics and onboard charger, generate heat during operation and charging.
From a thermal management perspective, BEVs present significant complexity compared to conventional vehicles. Many BEVs use two or more separate cooling circuits, for example, one for the battery, one for the power electronics and another for the cabin.
These loops may operate at different temperature ranges and require precise control. Some advanced systems integrate these into a thermal domain controller to optimize energy usage. This is why selecting the right coolant is essential to ensure optimal thermal management across the entire system.
Conventional coolants
Our proven internal combustion engines (ICE) coolants are already widely & successfully used in hybrid and battery electric vehicles (BEVs). Products like FREECOR® FTC, FREECOR® BMC and FREECOR® LPC help manage thermal loads efficiently while offering proven corrosion protection across a wide temperature range and system materials. This ensures strong passivation in both low-temperature battery cooling circuits and higher-temperature systems.
These coolants not only offer excellent thermal stability at high temperatures, but also provide effective corrosion protection across a wide temperature range. This ensures strong passivation in both low-temperature battery cooling circuits and higher-temperature systems.

Low e-conductivity coolants
Low electrical conductivity coolants play a key role in enhancing electrical safety in BEVs. The growing adoption of high-voltage systems and increasingly stringent safety requirements - especially in advanced EV markets like China - have introduced new demands for thermal fluids. In these environments, low electrical conductivity is essential to ensure system safety and long-term reliability.
To meet these evolving expectations, FREECOR® EV Milli coolants were specifically designed for applications where electrical insulation and operational safety are key. The low electrical conductivity of this range helps minimise current flow under voltage, limits fluid decomposition and hydrogen formation and aligns with the specific international safety standards set by leading EV markets.

Safe and Sustainable-by-Design
Electrification is driving innovation in powertrain and thermal management systems. Moving away from internal combustion engines is crucial to reducing greenhouse gases, air pollution, and their impact on the climate.
Other electric vehicle cooling solutions
Different electrified powertrains require different thermal management strategies. Discover how FREECOR® coolants support the specific cooling and performance requirements of Hybrid Electric Vehicles (HEVs) and Fuel Cell Electric Vehicles (FCEVs).
Hybrid Electric Vehicles (HEVs)
For HEVs the standard recommendation is to use the same coolant as for internal combustion engine (ICE) vehicles. Different designs are present with separated or isolated cooling circuits using the same coolant.
Fuel Cell Electric Vehicles (FCEVs)
FREECOR® EV Micro 10 ultra-low electrical conductivity coolant is designed for Fuel Cell Electric Vehicles (FCEVs). Compliant with the Chinese standard GB 29743.3 for FCEVs.
