BMW eDrive innovative technology in the new BMW 225xe and BMW 330e underlines once again BMW’s leading role in the premium segment concerning the powertrain electrification. BMW eDrive technology includes a series of cutting edge plug-in hybrid components and makes a significant contribution to reducing fuel consumption and emissions. Within the BMW EfficientDynamics suite of technology, BMW eDrive is one of the most cutting-edge elements.

Locally emission-free driving

BMW eDrive is the new drive system technology used in all the electrically powered vehicles from BMW i to the plug-in hybrid models from BMW. In addition to its outstanding efficiency and everyday practicality, BMW eDrive also delivers the highest standards in driving dynamics and quality, maintaining the brand’s tradition.

Alongside BMW TwinPower technology for internal combustion engines, intelligent lightweight design and optimized aerodynamics, BMW eDrive technology represents one of the most important elements of the EfficientDynamics strategy, designed to increase power and further reduce fuel consumption and CO2 emissions. In addition, BMW eDrive offers the option of driving on electric power alone and therefore with zero local emissions – ensuring, at the same time, the ability to cover long distances when  the two propulsion systems are combined.

Moreover, BMW eDrive technology provides dynamic acceleration off line due to the instantaneous responses of the electric motor, which immediately generates and incredible torque. In addition, eBoost function, that combines the torque of both drive systems under acceleration, contributes to the specific BMW driving pleasure, whatever the conditions.

Flexible development for different car concepts

The most important components of BMW eDrive technology are the synchronous electric motor (fully developed by BMW, including the electronic management of the engine), the lithium-ion high-voltage battery and intelligent energy management. The latter ensures that the electric motor and internal combustion engine in plug-in hybrid models work together as effectively as possible, depending on the situation of the moment.

Initially developed for the all-electric BMW i3 and BMW i8 plug-in hybrid sports car, the modular structure of BMW eDrive technology is perfect to be used in different concepts and automotive segments. BMW uses its vast technical experience and customer feedback in the development of the latest BMW eDrive models. The fine-tuning of vehicle-specific elements, such as the battery cells, cooling management, power electronics and operating strategy, has involved the transfer of knowledge from the BMW i3 and BMW i8 to the development of new BMW eDrive models.

Here, all of the components are adapted precisely to each vehicle concept and optimised in terms of performance, efficiency, safety and durability. Moreover, BMW eDrive technology enables  the electrified xDrive concept, first featured in the BMW i8, to be executed with high efficiency.

BMW eDrive: familiar BMW character, flexible usage options

Essentially, BMW eDrive technology includes the electric motor, the lithium-ion high-voltage battery and the power electronics. Based on a common eBoost strategy, all BMW plug-in hybrid models provides superior power delivery by bringing together their two propulsion systems and elevate the responsiveness and performance of BMW TwinPower Turbo technology to another new level.

Thanks to BMW eDrive, the electric drive in urban areas and on national roads is a commercially viable solution.  An important element of the operating strategy is the intelligent use of externally sourced and recuperated electric energy, in order to maximize the vehicle’s efficiency. BMW eDrive architecture’s components are adapted to each car concept and can be combined with three-and four-cylinder petrol engines as well as with classical rear-wheel drive, BMW xDrive or electrified all-wheel drive.

eDrive components developed as part of the BMW i projects will soon be integrated into other model ranges from the main brand. This scalable architecture provides the necessary basis to offer plug-in hybrid cars at attractive prices, at the same level as those of conventionally powered variants of similar output. Which means customers who opt for this advanced propulsion concept will enjoy not only the environmental benefits of electromobility, but also economic benefits.

Plug-in hybrid: energy management at its most intelligent

In plug-in hybrid vehicles, intelligent energy management ensures optimal combination between the use of internal combustion engine and electric motor in any situation. Their operating strategy is based on the vehicle starting up on electric power only. BMW’s plug-in hybrid automobiles gives priority to electric mode at low and medium speeds, allowing them to exploit the benefits of electric propulsion system, with zero local emissions.

Under greater acceleration and at higher speeds, the internal combustion engine joins the action. The boost function brings together the torque of both drive systems to maximize the car’s dynamic performance. BMW eDrive ensures an effective functioning (electrically assisted) of the heat engine and at higher speeds. This allows a reduction in fuel consumption on the national roads and motorways. And when the car’s navigation system is used, the proactive function initiates anticipatory operating strategy, which optimizes and maximizes the efficiency of electric driving experience.

Like the BMW i8, the BMW X5 xDrive40e, BMW 330e and BMW 740e also can – at the touch of a button in MAX eDRIVE mode – run on purely electric power up to 120 km/h (75 mph), and the BMW 225xe up to 125 km/h (78 mph). The internal combustion engine comes into action only when the accelerator’s kickdown threshold is passed.

In SAVE BATTERY mode, the battery’s charge can be maintained to enable electric driving at a later time in the journey. In the charge level drops below 50%, the battery is recharged. If the selector lever is moved into the S position, the combustion engine starts regardless of the mode engaged, which ensures a sustained availability of the combined maximum output of the two drive systems. In addition, The battery can be charged up to a level of around 80%.

By adding the BMW eDrive functions, ECO PRO, COMFORT and SPORT, are even better defined  than on conventional vehicles.

Fast and convenient battery charging

The high-voltage batteries of the new BMW plug-in hybrid models can be charged extremely easily, conveniently and quickly –  both at home and while on the move – using BMW 360 ° ELECTRIC solutions. The battery can be recharged from a domestic source using the supplied standard cable or from a BMW i panel (Wallbox; charging power: 3.7 kW). When it comes to recharging the battery during a journey, the BMW i mobility service, ChargeNow, gives customers easy access to the world’s largest public charging network, with over 30,000 charging points, managed by partners in 22 countries.

Higher performances, lower consumption

The new BMW plug-in hybrid models with eDrive technology, such as the new BMW X5 xDrive40e, the BMW 225xe and BMW 330e, that are currently making their debuts or the BMW 740e which will be released in the near future – are setting once again the standards in the various corners of the premium segment when it comes to reducing fuel consumption and will meet future requirements of international law regarding CO2 emissions.

Moreover, pure electric driving mode – with zero local emissions – will allow them to drive into city centre zones where entry is regulated. The BMW plug-in hybrid models will also deliver the BMW brand-specific attributes: dynamic excellence, sporting ability and driving pleasure, while providing the best performance in their respective segments.
