How Castrol on products work

Want to learn more about need for EV Fluids in electric vehicles and how Castrol ON’s EV Fluids help major car manufacturers? Discover more here:

Dry transmission EV fluids

Dry transmission EV fluids

Available to car manufacturers
 Available to workshops and distributors

The challenge

EV Transmissions can experience extremely high torque at low speeds and at the same time have to deal with more than double input speeds from the electric motor putting the fluid under immense stress. In addition, the limited range and resulting range anxiety need to be overcome.

 

Our technology

Castrol ON’s Dry EV Transmission Fluid resists the effects of working hard, providing enhanced protection, reduced viscosity loss and fast release of entrained air whilst enabling maximum efficiency.

 

The result

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.

Wet transmission EV fluids

Wet transmission EV fluids

Available to car manufacturers

The challenge

EV motors can experience 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

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.

Wet plus transmission EV fluids

Wet plus transmission EV fluids

Available to car manufacturers

The challenge

Future EV motor-transmissions can be enhanced by adding a shifting device to reach higher speeds, operate with synchroniser systems at high speeds and loads and to enable the e-Motor 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 synchroniser systems and clutches, allows efficient shifting under high loads and speeds and to operate the e-Motor in the most efficient range.

 

The result

Helps extend the life of the drivetrain system and help EVs go further1* on a single charge.

Thermal management EV fluids

Thermal management EV fluids

Available to car manufacturers

The challenge

Next generation battery electric vehicles are moving to direct cooling for battery thermal management in order to enable better vehicle performance and fast charging. Efficient direct cooling requires advanced dielectric coolant technology to maintain battery performance over the lifetime of the vehicle.

 

Our technology

Castrol has developed Castrol ON Thermal Management EV Fluid with advanced properties, to enable improved battery thermal management in your EV. Here is what makes it so effective:

  • Has lower viscosity levels than conventional dielectric fluids, such as transformer fluids.
  • Has strong electrical insulation, and a high flash point to protect your battery against breakdown and ignition.
  • Has oxidation resistance, which allows the fluid to maintain performance over fluid lifetime.

The result

An advanced Thermal Management EV Fluid, which can keep the battery in your EV cool in extreme conditions.

Grease EV fluids

Grease EV fluids

Available to car manufacturers

The challenge

Components of an electric vehicle face challenges such as electrical compatibility, durability, efficiency, endurance and corrosion that can significantly impact individual components and overall vehicle performance.

 

Our technology

Castrol has a range of high performance greases designed specifically for electric vehicle components to work at their best by:

  • Maximising bearing efficiency to extend vehicle range
  • Being compatible with an electrified environment to offer enhanced durability

 

The result

On-car lubricating greases for electric vehicles are specifically designed to address
efficiency and durability requirements of component manufacturers and assemblers.
