Electric vehicle fluids: Lubricating the future of mobility

Title: SHELL E-Fluids Transcript File

Duration: 2 minutes, 38 seconds

Description

The film explains why electrified drivetrains still require bespoke lubricants, what Shell can offer to OEMs developing the latest generation of battery electric vehicles and how all this fits into the agenda of making mobility more sustainable. The visuals are digitally generated.

[Visual]

We open with an urban scenery, a road with cars, buildings and people walking. At the side of the road is a traffic sign with an icon depicting a reduction of CO₂. The camera zooms into the yellow backdrop on the sign.

Contributing to low carbon mobility is part of the Shell Global Sustainability agenda.

[Visual]

Bubbles appear on the yellow backdrop, each one an illustration showinf an energy source or a fuel.

[Male Voice Over]

It includes a shift to lower carbon natural gas and renewable energy sources like wind and solar. For mobility specifically, it means a boost for biofuels, hydrogen, Liquefied Natural Gas and of course electric power.

Cut to a road with a car heading towards the viewer and stopping near a charging post. The cable is plugged into the car. The driver is sitting near the car reading a book.

[Male Voice Over]

E-mobility is coming and we at Shell are championing it. And there is one interesting thing: An electric drivetrain still relies on lubricants and thermal fluids! Actually, rather special ones are required! So, let‘s take a closer look...

[Visual]

The bodyshell of the car detaches from the chassis and moves up out of frame. The camera spins and goes up and now looks down at the drivetrain, with the battery pack and electric engine on show. A female Shell scientist appears with a smiling face. According to a small plate on the lapel of her lab coat her name is Lily . She points at specific parts of the drivetrain while explaining the details.

[Female Voice Over]

To start with, there is the battery pack. Batteries don't like heat or cold, they prefer it stable. You want to manage temperatures and mostly this means cooling the cells to keep them happy.

[Visual]

The casing of the battery pack moves up and out of frame. The cooling circuit is visualized with blue and red lines running to the radiator at the front of the car. We zoom into a battery stack and see the thermal fluid sloshing around the battery cells. Two cells are pulled out of the stack, fluid is dripping of the cells.

[Female Voice Over]

Our E-Fluid goes beyond, it is ready for immersive direct cooling, the future of battery thermal management. Here, the liquid is in direct contact with the cells, allowing for more effective cooling, which is essential for High Performance Charging - the faster you charge, the more waste heat you generate.

[Visual]

The camera zooms back and the lid is placed on the battery stack again. Lily appears in a close-up and point to the electric motor. The camera moves to the front of the car and spins around. The reductions gear housing magically disassembles and we see the gears spinning in an oil sump with the electric motor attached to it. The camera then moves to the motor and shows the spinning rotors with oil being sprayed on the copper end windings.

[Female Voice Over]

Then there are the electric motor and the reduction gears, which require greases for the bearings and lubrication for the gears. But it's not that easy: In a wet e-motor, reduction gears and the motor are integrated: the transmission fluid also has cooling duties in the motor, where it is sprayed on the copper end windings. Superior oxidation stability and copper corrosion resistance are key requirements, which conventional products fail to meet.

[Visual]

Cut to a technical yellow backdrop with Lily standing in the middle. She clicks on transparent screens in front of her and pictures of a senior scientist in a lab and a race car appears. Race cars speed from the left to the right behind Lily and finally pass herr left and right at great speed emitting a typical electrical sound.

[Female Voice Over]

So, after listening to our partners we went to the lab to develop a new range of lubricants. Next, we headed to the racetrack with Formula E to make sure they perform under the most challenging conditions.

[Visual]

Lily moves to the right, making room for a screen which shows the passenger car seen earlier morphing into a Formula E race car.

[Female Voice Over]

Everything we learned in Formula E has gone into the new products, from track to road, adding to our extensive lubricant expertise

[Female Voice Over]

The result is a complete range for electrified drivetrains, based on Shell Gas-to-Liquids technology and enhanced with unique additives:

[Visual]

Lily moves the right. She moves her right hand clicking on transparent screens, which magically appear showing packshots of Shell products. She moves the screens to the left where they end up in a staggered line.

[Female Voice Over]

Thermal Fluids for batteries, E-motors and inverters .... E-Fluids for wet and dry e-motors.... Electrical Motor Grease for bearings... and specific engine oil for plug-in-hybrids.

[Visual]

Panning shot with the chassis without the bodyshell driving on the same street we started with in the opening scene. The camera focuses on the battery pack, zooms out and spins round to the other side. The bodyshell drops down from above making the Battery Electric Vehicle complete, which accelerates and speeds off into the distance.

[Female Voice Over]

With our E-Fluids and E-Greases product family we can now provide our partners with an integrated portfolio that exceeds even future demands, contributing to making future mobility more sustainable today.
