Transmission EV Fluids
Advanced EV Fluids to protect your EV’s transmission, and extend the life of the drivetrain system.
Advanced transmission ev fluids for dry and wet E-Motors
Electric car transmissions
Unlike cars with combustion engines, which require a multi-speed transmission, the e-motor in an electric vehicle produces a consistent amount of torque, almost regardless of RPM. As a result, the majority of EVs feature a much simpler single-speed transmission, with an option for neutral and reverse gears too. That being said, it’s likely that – as the market’s offering of EV technology evolves – electric cars with multi-speed transmissions will become more widely available.
It’s important to note that the role of EV transmission fluid is even more vital in an EV. That’s because the demands on EV transmissions are more severe than conventional transmissions, with maximum torque delivered at low speeds and the increasing integration of electric motors. And EV transmissions are now evolving from a separate electric motor and EV transmission, to a combined system demanding more from the EV fluids.
Wet plus transmission EV fluid
The challenge
Future EV motor-transmissions can be enhanced by adding a shifting device to reach higher speeds, operate with synchronizer systems at high speeds and loads and to enable the eMotor to drive in the most efficient range.
Our technology
Castrol Wet Plus Transmission EV Fluid’s specially-developed technology, with its optimised friction levels for synchronizer systems and clutches, allows efficient shifting under high loads and speeds and to operate the eMotor in the most efficient range.
The result
Castrol Wet Plus transmission EV fluids help extend the life of the drivetrain system.
Castrol Wet Plus Transmission EV Fluid provides enhanced friction control allowing efficient and stable shifting under all driving conditions in multi speed gearboxes.
Wet transmission EV fluid
The challenge
EV motors can generate extremely high torque at low speeds. The transmission element has to deal with more than double input speeds from the motor and the motor unit operates immersed in the transmission fluid.
Our technology
Castrol Wet Transmission EV Fluid’s low viscosity formulation is specifically developed to deliver low electrical conductivity, enhanced system protection and helps the e-motor run cooler enabling it to operate at high efficiency.
The result
Castrol Wet Transmission EV fluids help extend the life of the drivetrain system.
Castrol Wet Transmission EV Fluid provides enhanced transmission cooling for improved e-motor performance and has reduced electrical conductivity compared to conventional fluids, protecting the motor against arcing.
Dry transmission EV Fluid
The challenge
EV motors can generate extremely high torque at low speeds. The EV transmission must deal with this and can face more than double input speeds from the electric motor, putting the lubricant under immense stress.
Our technology
Castrol Dry Transmission EV Fluid helps overcome the challenges the drivetrain system faces by providing enhanced protection, reduce viscosity loss and fast release of entrained air.
The result
Castrol Dry Transmission EV fluids help extend the life of the drivetrain system.
Castrol Dry Transmission EV Fluid provides enhanced transmission protection, helping extend the life of the drivetrain system and increase the vehicle range per battery charge.
