From Mini press: The all-electric MINI E will be powered by a 150 kW (204 hp) electric motor fed by a high-performance rechargeable lithium-ion battery, transferring its power to the front wheels via a single-stage helical gearbox nearly without a sound and entirely free of emissions. Specially engineered for automobile use, the battery technology will have a range of more than 240 kilometers, or 150 miles.
The MINI E's electric drive train produces a peak torque of 220 Newton meters, delivering seamless acceleration to 100 km/h (62 mph) in 8.5 seconds. Top speed is electronically limited to 152 km/h (95 mph). Featuring a suspension system tuned to match its weight distribution, the MINI E sports the brand's hallmark agility and outstanding handling.
By introducing the MINI E, the BMW Group is underscoring the resolve with which it works towards reducing energy consumption and emissions in road traffic. The BMW Group is drawing on its unique technological expertise in the field of drive systems to develop a vehicle concept enabling zero emissions without renouncing the joy of driving. Putting some 500 cars on the road under real daily traffic conditions will make it possible to gain widely applicable hands-on experience. Evaluating these findings will generate valuable know-how, which will be factored into the engineering of mass-produced vehicles.
The BMW Group aims to start series production of all-electric vehicles over the medium term as part of its Number ONE strategy. The development of innovative concepts for mobility in big-city conurbations within the scope of "project i" has a similar thrust, as its objective also includes making use of an all-electric power train.
Based on the current MINI, the car will initially be available as a two-seater. The space taken up by back-seat passengers in the series model has been reserved for the lithium-ion battery. When in use in the zero-emissions MINI, the battery unit combines high output with ample storage capacity and a small footprint with power ratios that are unrivalled in this field of application so far. The lithium-ion storage unit will have a maximum capacity of 35 kilowatt hours (kWh) and transmit energy to the electric motor as direct current at a nominal 380 volts. The rechargeable battery is made up of 5,088 cells grouped into 48 modules. These modules are packaged into three battery elements that are compactly arranged inside the MINI E.
The energy storage unit's basic components are based on the technological principle that has proven itself in practice in power supplies for mobile phones and portable computers. The MINI E's lithium-ion battery can be plugged into all standard power outlets. Its charge time is strongly dependent on the voltage and amperage of the electricity flowing through the grid. In the USA, users can recharge a battery that has been completely drained within a very short period of time using a wallbox that will ship with every MINI E. The wallbox will be installed in the customer's garage, enable higher amperage, and thus provide for extremely short charging times. Wallboxes fully recharge batteries after a mere two-and-a-half hours.
A full recharge draws a maximum of 28 kilowatt hours of electricity from the grid. Based on the car's range, a kilowatt hour translates into 5.4 miles. Besides the benefit of zero-emissions driving, the MINI E thus offers significant economic advantages over a vehicle powered by a conventional internal combustion engine as well.
