Integrated oil cooling circuit: BYDRecent Research Landscape

Thermal imbalances in high-torque hybrid drivetrains lead to premature component wear and efficiency losses. These innovations engineer the oil flow path to stabilize operating temperatures across the powertrain.

What technical problems is BYD addressing in Integrated oil cooling circuit?

High speed drivetrain thermal degradation

(31)evidences

Frictional wear and heat buildup in high-speed reducer assemblies lead to premature mechanical failure. Effective fluid distribution prevents component seizure and extends vehicle powertrain lifespan.

Inadequate powertrain component lubrication

(31)evidences

Excessive heat buildup in engine and transmission fluids leads to chemical breakdown and loss of viscosity. Preventing this degradation ensures consistent hydraulic control and component longevity in high-load hybrid powertrains.

Component thermal stress failure

(21)evidences

Excessive heat accumulation in high-power density electric drivetrains leads to insulation failure and mechanical wear. Effective thermal management prevents permanent damage and maintains operational efficiency.

Inadequate lubricant thermal management

(16)evidences

Fluid pressure fluctuations and mechanical vibrations within the lubrication circuit create acoustic instability. Reducing these disturbances prevents structural fatigue and improves operational quietness.

Inadequate powertrain thermal management

(15)evidences

Excessive heat accumulation within transmission and powertrain assemblies leads to lubricant breakdown and mechanical failure. Effective thermal management prevents premature wear and maintains structural integrity under high load.
