A nested epicyclic reducer and orthogonal differential fit high-speed electric drive into limited underfloor space while preserving torque and vehicle height.

Weighted comparison of cooling-circuit temperatures detects sensor or cooling faults early, helping protect EV motors and power electronics.

A flush charging flap uses sensor activation and a self-locking drive to prevent manipulation while keeping EV charging access easy.

A housing-fixed conductive contact beside the resolver cuts shaft-to-housing resistance, reducing potential difference and electric corrosion.

A free-floating engine mounted directly to the transaxle cuts chassis vibration, removes extra mounts, and keeps CVT center distance stable.

A reinforced bracket links the battery tray, rocker rail, and subframe to spread crash loads, limit tray deformation, and prevent wheel embedding.

An angled motor, intermediate, and drive shaft layout cuts powertrain width while supporting modular dual-motor packaging and larger motors.

A downstream side wall and elevated oil supply use pinion rotation to direct more lubricating oil to key gear surfaces.

By integrating a detachable battery assembly into the center frame module, this case cuts EV platform weight, parts, and cost while improving stiffness.

Integrated coolant lines in frame beams and traverses cool aligned battery cells while cutting pack height, weight, and underfloor space needs.

A heat conductive element links the stator to the transmission housing to even motor temperatures, improve cooling, and avoid spray systems.

Two symmetric drive units with separate automatic transmissions deliver switchable speed ratios for stronger climbing, acceleration, and high-speed cruising.

Coil and ambient temperature are used to estimate oil temperature, allowing reliable electric oil pump start timing without an oil sensor.

A reinforced inner cross member and force-redirecting bracket let outer sections deform in side impacts, protecting the battery from buckling damage.

A clutch and brake selectively bypass the planetary stage in EV transmissions, preserving low-speed torque while cutting high-speed losses.

A nested two-stage planetary layout raises reduction ratio while limiting axial size by routing the drive shaft through the rotor and sun gears.
