Best possible efficiency and performance that’s always available – intelligent energy management’s core task is to guarantee both of these. It also controls further functions from BMW EfficientDynamics that are specially coordinated for drivetrains with a synchronous electric motor.
Intelligent energy management optimizes the effectiveness of the electric drivetrain and the high-performance battery with a predictive operating strategy. Navigation data is used to calculate the optimum time to start driving electrically or charging the battery, in advance, depending on the most suitable route and driving situation. This saves up to ten per cent of energy – which allows the driver to cover a greater distance completely electrically. Brake Energy Regeneration ensures that kinetic energy released when braking or slowing down is saved in the lithium-ion high-performance battery, where it’s available at any time to increase the overall performance. With the ECO PRO mode, a press of a button is all it takes to gear all vehicle systems towards efficiency – and make intelligent use of energy reserves. In order to do this, intelligent energy management reduces the comfort functions according to the driver’s needs. In addition, the driver receives tips for particularly efficient driving via the Control Display, to help increase the maximum range.
