Series hybrid powertrain architecture: BYDRecent Research Landscape

Range anxiety and energy inefficiency in heavy duty cycles limit electric vehicle adoption. This architecture integrates internal combustion and electric drive units to optimize energy flow and extend operational distance.

What technical problems is BYD addressing in Series hybrid powertrain architecture?

Mechanical power transfer losses

(120)evidences

Mechanical instability during parking or power-down states in electrified drivetrains. Preventing roll-away ensures safety and regulatory compliance without manual intervention.

Inefficient wheel torque distribution

(39)evidences

Loss of control or efficiency due to poor power delivery across multiple axles. Correcting this ensures stability and performance in diverse driving conditions.

Excessive powertrain spatial footprint

(22)evidences

Limited packaging volume within the chassis prevents efficient mounting of heavy powertrain components. Optimizing spatial arrangement reduces vehicle footprint and improves weight distribution.
