BMW ActiveE concept was unveiled at the Detroit Auto Show on January 11th. BMW took the time to inform us about Concept ActiveE. In fact, it is the follow up for the Mini E. In total more than 600 units of the electric Mini hit the roads this year for tests in New York, Los Angeles, Berlin, London and Munich.

BMW ActiveE is an electric concept based on 1 Series Coupe. Officially called BMW ActiveE, the prototype is the second model, after the Mini E electric version, which is part of the new range of Megacity electric models that BMW Group will develop in coming years.

BMW ActiveE concept is different from anything at the outside compared with the production version of the BMW 1-Series Coupe, the only unusual visuals elements are the stickers that states that under the body is an electric engine. It takes place the heat engine and comes with interesting values power and torque: 170 hp and 250 Nm. The performances of the electric concept developed by BMW are interesting, with 9 seconds for 0-100 km/h and 145 km/h top speed, while the total autonomy of the engine power rises to 160 km. An item that is worth reported is the time that battery can be recharged at 220V battery, 180 minutes, time with 50% better than average electrical concepts announced to be series models that appeared so far.

Batteries used by BMW ActiveE Concept were made by Bosch and Samsung, are placed instead of the tank from a series version. This configuration allows a 50/50 distribution of masses, keeping all the rear seats that we find on gasoline production model version, minus only appear at the boot, whose volume has descended to 200 liters.

Technology:

The BMW Concept ActiveE is powered by a new synchronous electric motor specially developed for this vehicle. Its maximum output is 125 kW/170 bhp, the maximum torque of 250 Nm / 184 lb-ft is available from standing as is typical for electric motors and remains available over an unusually broad load range.

For the first time, electrical energy is stored in a lithium-ion battery pack developed jointly by BMW and the co-operation partner SB LiMotive especially for the BMW Concept ActiveE. A new stable temperature regulation function optimizes the battery pack’s performance.

Other characteristics of the drive technology used in the BMW Concept ActiveE are the weight-reduced construction and the package-optimized arrangement of all components. The electric motor is completely integrated in the rear axle, the power electronics is positioned above the motor. Space is used for energy storage which in vehicles powered by a combustion engine would be taken up by the conventional drivetrain and fuel tank. With a weight of some 1,800 kilograms / 3900 lbs (unladen weight according to DIN), a low center of gravity and an axle load distribution which is typical of a BMW, the vehicle has everything it requires to provide the dynamic driving properties and agile handling in the style of the BMW 1 Series.

Predicted driving performance figures: acceleration from zero to 60 km/h (37mph) in less than 4.5 seconds and from zero to 100 km/h (62mph) in less than 9 seconds, maximum speed: approx. 145 km/h (90 mph, electronically limited). As with the MINI E, the real-world range is expected to be about 160 km / 100 miles on a single charge, depending on conditions (FTP72 cycle range is calculated to be 240 km / 150 miles in simulation).

Flexible charging technology enables the lithium-ion battery pack to be recharged by a conventional power outlet at public charging stations or at a special wall box. On the European grid, the battery pack can be fully charged at a high-current power outlet (50 ampere) in as little as 3 hours. In North America, using a high-current (32 ampere continuous) residential wall box, the charge time is about 4.5 hours.

The drive components used in the BMW Concept ActiveE have been developed as part of project i. The objectives on which this is based are derived from the requirements for the serial production development of a Megacity Vehicle.

In the BMW Concept ActiveE, new BMW ConnectedDrive services are presented which have been designed exclusively for use in an electric vehicle. This includes specific remote functions which enable the use of a mobile phone to check the charge status of the battery, search for public charging stations and activate the vehicle’s auxiliary heating and air conditioning functions.
