Recently, the Chinese BYD EV mileage of the drive motor and other key technical parameters of release, new energy network intelligence analysis on the impact of state judged the depth of this model and related technologies like radiation surrounding models .
Note: The Chinese version of the EV drive and two-wheel-drive version of the model parameters specific to BYD official release of information shall prevail.
In 2020, the second installment of “new energy vehicles recommended list,” the Ministry of Industry, the Chinese BYD EV is divided into two drive and four-wheel drive version and adapted the same iron phosphate lithium cell assembly (energy density 140wh / kg); 4 pre-drive version of the driving motor maximum output power of 163 kilowatts, the maximum output power of the rear drive motor 200 kilowatts, with maximum speed of 15,500 revolutions / min; only two quban Configuring a maximum output power of 163 kilowatts pre-drive motor; siquban NEDC mileage 550 km; two drive version NEDC mileage 605 km.
Integrated recent months BYD sustained release information see Han BYD EV cell assembly adapted to power the latest “blade” style no battery module packaging technology + super lithium iron phosphate system, to increase the safety of the premise of low and high temperature environment adaptability.
1, BYD in electric drive technology with the state:
Interestingly, before and after Han EV4 drive version of the adaptation of the drive motor is different from the 2019 – February 2020, in the sale, the use of “e platform” technology solutions Tang EV, Song Pro EV, Qin Pro EV, EV and e yuan series cars.

The picture shows late 2018, BYD official release for “e platform” technology solutions system, 4 different power level “3-in-1” comparison table drive system parameters. Wherein 120 kilowatts level “3 in 1” speed electric drive assembly 14000 rev / min; 180 kilowatts level “3 in 1” level drive assembly speed was 14,000 rpm / min.
120 kilowatts level “3 in 1” electric drive assembly is first applied Qin Pro EV500 models; 180 kilowatts level “3 in 1” is used in the electric drive assembly Tang two EV drive / four-wheel type .

120 kilowatts this stage clearly marked maximum speed of 15000 rev / min on the “3 in 1” level drive assembly plate.

Photo August 2019, the author captured EV Tang front wheel drive 180 kilowatts level “3 in 1” electric drive ASSEMBLY close-up detail. Whether or paste nameplate Shakespeare Di Guanxuan, have confirmed the adaptation of Don EV-wheel-drive version of “3 in 1” electric drive assembly maximum speed of 15,000 rev / min.
2, Han EV electric drive wheel drive state of the art to predict:
Looking back at Han EV electric drive wheel drive state of the art, the maximum output power of the motor pre-driver 163 kilowatts , the maximum output power of the rear drive motor 200 kW rpm with a high speed of 15,500 revolutions / min.
Although BYD official did not release any technical details about the many Chinese EV electric drive technology, but BYD pushing “e platform” technology solution with a modular set easy to sell fast and flexible technical architecture of recombination of different electric vehicles to other OEMs. BYD production using “e internet” technical solution models, the adaptation stage 40 kilowatts 70 kilowatts at 120 kilowatts and 180 kilowatts “3 in 1” electric drive assembly at the same time, for some facelift electric Vehicle adaptation of the “3-in-1” drive assembly “stretched” from one kilowatt retrofit out.
in December 2018, BYD launched a more powerful Qin Pro EV600 electric vehicles. Qin Pro EV600 in EV500, based on the adapted group of 135 kilowatts maximum output power, maximum speed 15,000 rev / min. “3 1” drive assembly. Indeed 120 kilowatts and 135 kilowatts “3 1” drive assembly, share the same technical state of the hardware main body 1, two write control software state of the art.
by writing different control software, hardware shared mature body, can minimize costs and maintain system reliability and stability, in line with BYD has consistently adhered to the “mature technology + technology + appropriate vehicle platforms” iterative development model.
New Energy Intelligence Analysis with anticipation, Chinese EV-wheel-drive version will still use sophisticated “e platform” technology solutions in the high version of the “3 in 1” high power system assembly, the maximum output power 180 kilowatts, the maximum speed 15,000 rev / min “3 in 1” body electric drive assembly hardware.
180 kilowatt EV siquban adapted Tang “3 in 1” level based on the drive assembly, the drive motor for front wheel drive in EV Han reduced power, the rear drive motor or power while the maximum speed up to 15,500 rev / min.
before and after Han EV-wheel-drive version of the drive motor power output policy adopted “after former light heavy”, brings the greatest benefit is to enhance the handling of a straight line. In the uniform paved road driving conditions, with a smaller power of 163 kilowatts output level “3 in 1” drive assembly, can reduce power consumption of 100 km; in the “full throttle” speed driving conditions, the rear 200 kilowatts and the front stage 163 kilowatts level “3 in 1” level drive assembly cooperative operation, after the vehicle running attitude prefer to drive performance win.
It is noted that, Han adapted EV “3 in 1” level of the drive assembly up to maximum speed 15,500 rev / min, mean 100-120 km / h high-speed cruising conditions, can be get relatively lower overall power consumption.
I have something to say:
developed to a certain level when the hardware status, software control to enhance the strategy is driven by the evolution of the efficiency of the vehicle. Group 2 is mounted on the ratio of the maximum output power of 160 kilowatts level, maximum speed 12,000 rev / min “2 in 1” drive motor adapted first generation EV electric four-wheel drive four-wheel drive version of the song (not production); group 2 is mounted before the maximum output power 16 is mounted; the maximum output power 180 kilowatts, the maximum speed 15,000 rev / min “3 1” drive assembly, adapted second generation EV electric four-wheel drive four-wheel drive version of Tang (sale)3 kilowatts, 200 kilowatts rear stage, the maximum speed of 15500 rev / min “3 1” drive assembly, the third generation Chinese EV electric wheel drive four-wheel drive (the upcoming production), the electric four-wheel drive technology BYD enhance the ability to model and integrate more and more with ease.
If the Chinese EV-wheel-drive version of the electric drive technology is indeed from upgrading existing technology, then without changing the hardware, without increasing the weight of the premise, improves vehicle handling performance, handling complex road, in “blade” style-free battery module packaging technology + support under the super lithium iron phosphate, BYD launched in 2020 and thereafter a breakthrough in high-end electric car will pull to China’s new energy industry again.
In 2018, BYD articles on technology and vehicle development written by the author clearly states that no subsidy era, who can simultaneously reduce costs, enhance vehicle safety, will get more market share .
in the upcoming Chinese EV siquban to the premise of safety “blade” style no battery module packaging technology super lithium iron phosphate + cells; reduce costs while improving the driving safety of the vehicle 3 generation electronic four-wheel drive technology, beyond those who still struggle with mileage with other cars and ignore important security.
Of course, the “blade” style no battery module packaging technology in conjunction with the vehicle is not simple, requires a minimum forward model adapted to the development, the battery system is completely “absorb” welded to the underbody, advantage of the use of the vehicle structure itself to provide longitudinal and transverse battery protection system.
On the whole, from the Han EV-wheel-drive version can glimpse at least three years ago, BYD electric drive technology, battery technology and the highest level of vehicle manufacturing capacity.
More detailed technical interpretation, will continue to launch in the car in place after the test.
