Titanium Media reported on July 14 that the BMW Group released an innovative pure electric BMW iX3 for the global market. As the first model to be equipped with the latest fifth-generation BMW eDrive electric drive technology, the new car will bring zero emissions, long battery life, high energy efficiency, and pure electric driving pleasure to BMW users worldwide.
BMW has a very early layout in the field of new energy. As early as 1972, BMW developed its first electric vehicle. It has accumulated rich experience in this field. The BMW brand in China has accumulated more than 60,000 new energy vehicle customers. .
There are already i3, i8 and other new energy products including the i series, and many existing products are also deployed in corresponding hybrid models, such as BMW 7 series, BMW 5 series, BMW X1 and other models. Today's BMW iX3 is also a newly designed pure electric vehicle.
As early as the development stage, BMW decided to develop a variety of models including pure electric, plug-in hybrid, gasoline and diesel drives based on the same platform to give customers more "power of choice."
In China, the innovative pure electric BMW iX3 has been included in the "New Energy Vehicle Promotion and Application Recommended Model Catalogue" of the Ministry of Industry and Information Technology, which means that this product has begun mass production and will soon The official debut is different from the PPT car made by many new car companies. Traditional car companies like BMW usually make public announcements after everything is ready.
It is reported that in the third quarter of the second half of this year, this new car will be the first to be marketed in China and exported overseas with Shenyang, China as the only production base, showing that China's production base is playing an increasingly important role.
BMW i brand exclusive design language
The exterior design of the innovative pure electric BMW iX3 adopts the BMW i brand exclusive design language.
BMW’s classic kidney shape is outlined with blue shadows, and the middle area adopts a simple and technological black panel as a whole, and a hidden semi-closed structure is designed to reduce wind resistance and retain air intake and cooling Features. On the side, the blue plaques running through the front and rear are used under the doors. Two blue spoilers are designed on both sides of the lower part of the rear of the car, which not only has aerodynamic functions, but also allows people to identify its new energy vehicle at a glance.
The new model adopts the latest generation of aerodynamic wheels, which can reduce aerodynamic drag by 5% compared to fuel-fueled models. The new generation of aerodynamic wheels is based on lightweight aluminum alloy wheels, and inserts with aluminum alloy texture are embedded between the V-shaped spokes, which can not only carry various mechanical impacts in dynamic driving, but also reduce aerodynamic turbulence. The effect of reducing air resistance. Compared with the previous BMW aerodynamic wheels, the new wheels reduce the weight by 15%, reduce the unsprung mass, optimize vehicle handling performance and improve vehicle energy efficiency.
In the Chinese market, the innovative pure electric BMW iX3 will be equipped with the same smart technology and the same luxury quality as the X3 gasoline model, and will be produced by BMW Brilliance in flexible co-line production. These measures have led to the development of the innovative pure electric BMW iX3 And production efficiency can be improved, so that the marketization of new energy vehicles can truly achieve sustainable development.
is equipped with the fifth-generation BMW eDrive
BMW’s exploration of electric technology is very early, thanks to BMW’s strong presence in the field of electrification With technology accumulation, the fifth-generation BMW eDrive electric drive system on the BMW iX3 has fully evolved in the three core areas of battery, motor and electronic control, including power density, cruising range, lightweight, miniaturization and modularity.
The high-voltage battery system of the innovative pure electric BMW iX3 will be produced by the second phase of the BMW Brilliance Power Battery Center, using a higher-tech 811-type nickel-cobalt-manganese ternary lithium-ion battery.
Compared with the existing BMW electric models, the energy density of batteriesThe battery pack has a total capacity of about 80 kWh and a net capacity of 74 kWh. The energy density of the battery pack system is as high as 154 watt-hours/kg, which can provide vehicles with up to 500 kilometers of zero-emission pure electric driving range. At the same time, the battery has achieved a perfect balance in terms of performance, energy density, cruising range, safety, and quality and reliability throughout the life cycle.
In addition, the drive unit also uses breakthrough technology, integrating the electric motor, electronic control, gearbox and inverter for the first time, and the power density is improved compared to the existing BMW pure electric models Up to 30%. The drive unit adopts an excitation synchronous motor and does not use rare earth elements, reducing the dependence on scarce resources. With a maximum output of 210 kilowatts and a maximum torque of 400 N·m, a single drive unit can enable the innovative pure electric BMW iX3 to accelerate from 100 kilometers to 6.8 seconds.
In the NEDC standard test, the energy consumption per 100 kilometers is only 16.7 kWh, setting a new benchmark for the same level of luxury electric vehicles. The drive unit is also creatively integrated with the rear axle of the vehicle. While the structure is more streamlined, it also makes the power output more efficient and direct, bringing a pure rear-drive driving experience.
The integrated charging unit used in the innovative pure electric BMW iX3 integrates the vehicle's DC and AC charging control and management functions. Within the scope allowed by the Chinese power grid, high-speed DC charging is used, and the maximum charging power of the vehicle can reach 100 kilowatts. It only takes 45 minutes to charge the battery from 0 to 80%. AC charging is also very efficient, with a maximum charging power of 11 kilowatts, and it only takes 7.5 hours to charge the battery from 0 to 100%.
The fifth-generation BMW eDrive electric drive technology is the key to the sustainable development of the BMW Group’s development of electrified models in the future. In the future, this technology will also be applied to the BMW i4 production version and BMW iNEXT production version. (This article first published Titanium Media APP, editor/Li Yupeng)
