As electric vehicles (EVs) performance and efficiency improve, challenges arise in effectively lubricating and cooling vital components such as gear meshes, bearings, and stator stacks. Traditional lubrication solutions struggle in EV systems due to their lower pressures, resulting in inefficient cooling and lubrication.
The Lee Company’s Targeting Orifice Demo demonstrates how our innovative orifice technology can produce a steady, high-velocity fluid stream even at low pressures—precisely targeting hot spots to ensure optimal performance. By using Lee orifices, designers can minimize fluid use, downsize electric oil pumps, reduce total system weight, and enhance overall energy efficiency. This contributes to an extended vehicle range and a more sustainable driving experience.
Discover how our solutions are driving the future of electric mobility—targeted performance, maximized efficiency.
Unlike traditional internal combustion engines, EVs rely on a complex cooling system to regulate the temperature of various components, such as the battery, motor, and power electronics. These systems play a crucial role in ensuring optimal performance and extending the lifespan of the vehicle’s components. Effective cooling is essential for EVs due to the high heat generated by the electric powertrain. The battery, in particular, requires proper cooling to maintain its performance and longevity. Without adequate cooling, the battery can overheat, reducing its efficiency and potentially causing irreversible damage. Additionally, the motor and power electronics also generate heat during operation, which needs to be dissipated to prevent overheating and ensure optimal performance.
This video goes inside an electric vehicle gearbox. These are simple devices which simply reduce the speed of the electric motor and house the differential. This particular reduction gearbox is from a Hyundai Ioniq Electric 28kWh that’s done 100,000 miles. All the Kia & Hyundai EVs use a very similar reduction gear.
