On May 28th, BYD released the fifth-generation DM technology.
Wang Chuanfu, chairman and president of BYD Co., Ltd., said that the fifth-generation DM technology will achieve 2.
9L/100km, comprehensive battery life 2100km, and engine thermal efficiency of 46.06%. Seal 06 (parameter | inquiry) equipped with the fifth generation DM technology, the fuel consumption in NEDC mode is 2.
9L / 100km, the power consumption in NEDC mode is 10.
7kWhhand / 100km / 100km/h and accelerates to 7.5s. , 
, , , from 2008 to 2021, BYD experienced four generations of DM, the first generation adopted double motor series-parallel architecture, the second generation applied multi-speed DCT parallel architecture, entered the 542era, and the third generation brought multi-speed DCT hybrid architecture to improve performance.
The fourth generation of dual-motor series-parallel architecture has become a subverter of fuel vehicles, launching DM-i (main fuel economy), DM-p (main performance) and DMO (main off-road).
, , , the fifth generation DM technology is based on the fourth generation DM technology, and the fifth generation DM technology realizes 1.
5L plug-in special engine with a maximum power of 74kW and a maximum torque of 126Nm.
equipped with 10.
08kWh and 15.
87kWh special power blade battery.
EHS electric mixing system EHS120 maximum power 120kW, maximum torque 210Nm, EHS160 maximum power 160W, maximum torque 260Nm The life of 12V lithium iron phosphate small battery is the same as that of the whole vehicle, and lead-free is realized.
, the engine adopts up to 16 ultra-high compression ratio, with high tumble port, intelligent combustion system, intelligent EFI system, EGR before catalyst, intelligent split cooling, intelligent variable lubrication system.
, 
, EHS electric mixing system comprehensive operating efficiency of 92%, efficiency increased by 5%, power density 75.
47kW/L, increased by 15.5%. Insert and mix special blade battery energy density 115wh/kg, increase 15.9%. discharge rate 16C, increase 33%.
feedback rate 5C, increase 20.3%. extremely safe, extreme average temperature.
, 
, , in terms of charging, AC slow charge is upgraded from 3.
3kW to 6.
6kW, the charging time is reduced by 60%.
DC fast charge SOC 30% is only 21 minutes, although the charging time is 36% short.
external discharge is upgraded from 3.
3kW to 6kW.
, 
, , , 12V lithium iron phosphate small battery, the world’s first mass production carrying, weight reduction, and lifetime farewell battery replacement.
The fifth generation thermal management architecture has been upgraded to the height of the overall architecture, with front cabin thermal management, cockpit thermal management and battery thermal management.
Energy consumption can be saved by 10% at high temperature and 8% at low temperature.
The pulse self-heating of the brand-new second-generation battery can realize self-heating in charging, driving and parking, and the heating rate can be increased by 60%.
In the aspect of cabin thermal management, the efficiency of the compressor is improved, and the cabin temperature control speed is faster.
