Electric Vehicle Lubricant and Fluid Testing

EV Drivetrain Lubricant Testing - The evolution of fully electric and hybrid transportation continues to evolve and the same is true with the test methods and equipment for those critical areas of interest.

Performance Characteristics of Lubricants in Electric and Hybrid Vehicles: A Review of Current and Future Needs

Electric and hybrid vehicles are gaining increasing attention in recent years. The distinguished difference between electric/hybrid vehicles from conventional ones is the intermittent on-and-off control of the internal combustion engine, whereas the electric vehicles operate on electrical...

Ill be interested to see how this goes.

Its a systems engineering issue, and an interfaces issue. What’s the need when creepage, clearance, dielectric standoff, common mode, etc. wasn’t sufficiently bad due to lower voltages, lower power levels, power electronics running at narrower ranges of design…

Now we want higher voltages to get more power and various other advantages, and more physics come into play…

What do you think of/know about Dexron 212B ATF?

It's a special EV-specific ATF that GM says not to use in regular automatics

What do you think of/know about Dexron 212B ATF?

It's a special EV-specific ATF that GM says not to use in regular automatics

It has a viscosity of 5.95 cSt @ 100°C, and is mainly composed of base oils and a VII.

No indication of S-P contents (as of yet) which might affect copper components.

I figure this has to happen eventually. Everyone goes on about maintenance free but Tesla used to recommend changing the differential fluid every 50k miles, but they seem to have done away with that interval. That's something I would care about keeping serviced.
