On April 4th, media sources unveiled a patent related to BYD's hybrid powertrain, speculated to be the latest DM 5.0 hybrid system from BYD.
According to the patent diagrams, this cutting-edge hybrid powertrain adopts a similar dual-motor series-parallel configuration as the existing DM-i system, albeit with a more intricate structure.
There have been two significant changes in the hardware architecture. Firstly, all motor outputs now pass through planetary gear reduction mechanisms, and secondly, dual-clutch systems are employed to control power flow.
The new system supports several modes: series hybrid, dual-motor pure electric, single-motor pure electric, and parallel output of dual motors + engine.
Thanks to the adoption of a dual-clutch system, the new system introduces a dual-motor pure electric mode, further enhancing the power performance in electric-only mode compared to the DM-i.
Additionally, at BYD's recent earnings conference, Wang Chuanfu, the chairman of BYD, announced that the fifth-generation DMI hybrid technology will be launched in May this year, boasting a fuel consumption reduction to 2.9 liters per 100 kilometers and a combined fuel and electric range of 2,000 kilometers.
Wang stated that due to the current demand exceeding supply, the transition to the fifth-generation DMI models will gradually take place in May, based on market conditions. The anticipation is that the popularity of the fifth-generation DMI models could extend for another 1 to 2 years.
