EV Fluid

    Today's environmental challenges have clearly put energy transition under way, and the resulting regulations are forcing the automotive industry to innovate constantly while responding to user expectations for quality and performance.
    With the rising concern over tailpipe emissions prompting stricter standards for carbon dioxide and pollutants, demand of hybrid and electric vehicles are rapidly growing. In 2020, there were more than three million electric vehicles (EVs) sold which grew by 43% year on year. According to various scenarios, EV sales are expected to account for 90% of the light duty vehicles market by 2040 with some car manufacturers announcing that they would stop manufacturing internal combustion engine (ICE) models in the coming decades.
    As a trusted partner to car manufacturers, TotalEnergies Lubrifiants aims to become the responsible energy major to deliver technical, people-oriented solutions and sustainable performance. Our goal is to promote cleaner mobility that is better for both people and the environment.

    New product ranges in respond to the changing industry & new technical requirements

    In light of the profound changes shaping the automotive industry, TotalEnergies Lubrifiants started developing new types of fluids to meet the new technical requirements of hybrid and electric vehicles – thanks to the extensive Research & Development efforts and commitment.

    Three product lines are developed in this context:

    Fluids for electric vehicles

    In the automotive world, the future is all about electric cars. 
    In the next decade, electric cars are expected to become the world’s top selling automobiles. 
    Even though electric vehicles don't need engine oil, they do need specific fluids. As EVs become increasingly powerful and their battery range and charging speeds improve, standard fluids are unable to keep up in terms of robustness, heat resistance and cooling capacity.
    That’s why TotalEnergies developed Quartz EV Fluids, a range of fluids that was specifically designed for electric vehicles. 

    Quartz EV Fluids are backed by major R&D efforts and tailored technical solutions to address the new electrical, thermal and material compatibility of electric vehicles.

    New technical requirements of EV Fluids

    Fluids with Specific Technical Properties for Unparalleled Lifespan New technical constraints for the electrification of vehicles require the development of new fluids that must meet the following properties:

    icon1-png

    Insulation augmented

    Fluids used in electric vehicules require electrical insulation properties.
    The fluid must be insulating to prevent any arcing sinceit is going to be in close contact with the electrical and/or electronic components of the vehicule.
    Dielectric properties must remain stable throuhhout the time despite harsh operating conditions like rising temperatures, oxidation, humidity and particle abrasion.

    Thermo-Control Augmented

    Lithium·Ion battery has its maximum efficiency within a very short temperature range.
    Having a temperature above or below this range will drastically impact the performances and the lifetime of the battery.
    It is therefore mandatory to ensure that the thermal management of the battery allows it to work in this temperature range even under extreme conditions such as fast charging or hot and cold climate.

    Compatibility Augmented

    Material compatibility is critical to the fluids used in electric vehicles due to large amount of copper present in the components, especially e-transmissions.
    It is mandatory for fluids to provide protection against corrosion and to ensure its consistent performance throughout the drain interval.
