Awaited with suspense.

The energy management of the
BMW Concept 7 Series ActiveHybrid.

At the core of every hybrid vehicle is the battery. It has to deal with full load peaks, irregular loading cycles and mechanical wear and tear without losing any of its capacity as well as offering high energy density. New, lithium-ion batteries are integrated in the BMW Concept 7 Series ActiveHybrid, which far exceed the performance of conventional battery units. The batteries are connected to the electric motor and other components via the 120V, on-board network. This enables the ongoing use of the air conditioning system even when the Auto Start Stop function has switched off the petrol engine.
