The world of electric-powered vehicles has arrived upon us and is definitely here to stay. Just one quick glance at TV adverts shows virtually all the OEMs advertising their hybrid or fully electric-powered vehicles at the expense of internal combustion engine (ICE) options. The International Energy Agency has produced statistics looking at the passenger cars stock over the last decade and it shows that globally, hybrid and battery electric vehicles (BEVs) have grown in the marketplace exponentially. In 2020, there were over 10 million hybrid or electric vehicles present across the globe, and in all regions, BEVs have outstripped the traditional plug-in hybrid.
With all the work and emphasis placed on electrically powered vehicles, we have to stop and think about the lubrication regimes for these vehicles.
Traditional combustion engine vehicles require the use of an engine oil, a transmission oil, maybe an axle oil and some greases. A new modern battery-powered vehicle does not require engine oil and most of the focus now sits with the transmission oil, however, this is now no ordinary transmission oil. Even though all of the traditional requirements of the transmission oil are still needed, such as anti-wear, extreme pressure protection, frictional balance and high levels of antioxidancy, there are now added demands placed on the fluid. These demands come in the shape of electrical compatibility as the transmissions are now driven by an electric motor and this motor is directly in contact with the transmission fluid.
The formulator now must consider several factors:
So the formulator has an exceptionally difficult job balancing all the requirements of a new modern E-axle with the needs of a traditional transmission system, and of course, they have to do this in a low viscosity fluid in order to maintain the high expectations of fuel economy required by the market and the end user.
All this work does not take into account one major new component in an electric vehicle and that is the battery. The battery is the most expensive component of the electric vehicle and requires protection and maintenance to keep up longevity and efficiency for as long as possible. Rechargeable batteries operate within a temperature window, and fast charging and high power draws will raise the temperature significantly in contrast to very low ambient temperatures which cool the battery to temperatures outside of its optimum operating range.
Today, traditional methods of temperature control are utilised such as air cooling and indirect water-glycol mixtures. The issue with these techniques is that the heating or cooling is inefficient and significant temperature gradients can be experienced across the battery. This limits the life of the battery and reduces its operating capability. More modern methods involve full immersion of the battery in a liquid coolant, to maximise the cooling and minimise the temperature gradient, but this also brings its own problems.
Ultimately a battery coolant fluid needs to be a specialist fluid, designed for the job, and specialist esters are generally taking centre stage for this application.
The new world of electric-powered vehicles is very exciting but it brings with it a new set of problems for the lubricant engineers but is a challenge that they will continue to rise to through innovative solutions.
