Recently, the media exposed a patent for BYD’s hybrid power system, suspected to be the latest DM 5.0 hybrid system from BYD.
The patent diagrams show that this latest hybrid power system adopts the same dual-motor series-parallel configuration as the existing DM-i system, but with a more complex structure.
With a full tank of gas and a full battery charge, the range can reach up to 2000 kilometers. Suspected BYD DM5.0 hybrid patent exposure.
There are two significant changes in the hardware structure: firstly, the motor outputs are all passed through planetary gear reduction mechanisms, and secondly, dual clutches are used to control power flow.
The new system supports several modes, including serial range extension, dual-motor pure electric, single-motor pure electric, and dual-motor + engine parallel output.
With a full tank of gas and a full battery charge, the range can reach up to 2000 kilometers. Suspected BYD DM5.0 hybrid patent exposure.
Due to the adoption of dual clutches, compared to the DM-i, the new system adds a dual-motor pure electric mode, further improving the performance of pure electric mode.
In addition, during BYD’s recent financial report conference, BYD Chairman Wang Chuanfu stated that the fifth-generation DMI hybrid technology will be launched in May this year, with fuel consumption reduced to 2.9 liters per 100 kilometers and a range of 2000 kilometers on a full tank of gas and battery.
Wang Chuanfu mentioned that due to the current situation of demand outstripping supply, the transition to the fifth generation of DMI models will gradually take place in May according to market conditions, and the popularity of the fifth-generation DMI models is expected to last for 1 to 2 years.
