All performance fluids and lubricants in a battery's life
The battery is a central component of electric vehicles and is crucial for the driving range, performance and service life of the vehicle.
Lubricants and other FUCHS products are used throughout the entire service life of the battery – from production and assembly through to actual operation in the vehicle.
As a leading lubricant partner to the automotive industry, we know what is important in each phase, support them with our extensive portfolio and expert knowledge and help to further develop this technology.
We not only focus on high-quality lubricants, but also drive innovation in the field of e-mobility. This is demonstrated by the partnership between FUCHS and E-Lyte, a start-up that specializes in the development and production of advanced electrolyte solutions.
Whether metalworking fluids for the production of battery housings, thermal fluids to ensure the optimum operating temperature or lubricating greases for the conductivity of plug connections – FUCHS is the reliable expert for solutions in e-mobility.

Liquid cooling options for batteries
The battery is the heart of every electric vehicle. They require an operating temperature of 18°C to 25°C in order to function optimally. This puts them under considerable thermal stress - both during operation and during the increasingly rapid charging processes. Cooling fluids protect the battery from overheating and ensure that the service life of the cells is maintained. There are two different types of liquid cooling.
Immersion cooling with thermal fluids
The oil-containing thermal fluids (TF) are dielectric fluids and are in direct contact with the components to be tempered, which are immersed in this liquid. The fluid acts as an electrical insulator, absorbing the heat directly from the battery and transporting it away. As the battery is in direct contact with the thermal fluid, a very even temperature distribution is achieved, which has a positive effect on the service life and efficiency of the battery.
Requirements for thermal fluids for battery cooling:
- Thermal conductivity
- Viscosity & Density
- Specific heat capacity
- Material compatibility
- Bearing protection (e-motor)
- Compatibility with sealing materials
- Electrical conductivity
Highlight of the FUCHS BluEV portfolio:
Indirect cooling with EV Coolants
As a counterpart to dielectric fluids, EV coolants stand for indirect cooling (jacket cooling). This fluid circulates through a pipe system that surrounds the battery. It absorbs the heat and is dissipated through a heat exchanger or radiator. In contrast to thermal fluids, EV coolants contain water, making them excellent heat conductors and thus contributing to optimum thermal management. The energized components are not in direct contact with the components.
Requirements for EV coolants for the cooling of batteries:
- Corrosion protection
- Material compatibility, especially with aluminum alloys
- Compatibility with sealing materials
- Thermal conductivity
- Viscosity & density
- Specific heat capacity
- Electrical properties
