Hydraulic powertrain thermal management architecture: BYDRecent Research Landscape

Thermal instability in hybrid powertrains causes component degradation and efficiency loss. These innovations utilize integrated hydraulic cooling circuits to maintain optimal operating temperatures.

What technical problems is BYD addressing in Hydraulic powertrain thermal management architecture?

Drivetrain component thermal fatigue

(31)evidences

Frictional heat and mechanical wear within the reducer housing lead to premature component failure. Ensuring consistent fluid delivery prevents thermal degradation and mechanical seizure in high-load drive assemblies.

Inadequate component thermal regulation

(27)evidences

Uncontrolled thermal buildup in hydraulic transmission fluids leads to viscosity degradation and component wear. Managing this heat prevents mechanical failure and maintains hydraulic control precision.

Component overheating and friction loss

(18)evidences

Fluid-borne pressure pulsations and mechanical vibrations in pump systems create excessive noise levels. Reducing these disturbances improves operator comfort and vehicle refinement.

Inadequate transmission lubrication distribution

(13)evidences

Frictional heat and mechanical wear in power assemblies lead to component failure. Effective thermal and fluid management prevents transmission degradation and energy loss.

Inadequate lubricant thermal regulation

(12)evidences

Fluctuating oil temperatures lead to viscosity breakdown and accelerated component wear. Maintaining optimal thermal states prevents mechanical friction losses and engine failure.
