The new BMW 5 Series - high-voltage battery with compact design and high energy content

Just like the drive units, the high-voltage battery used in the two all-electric model variants of the new BMW 5 Series Sedan is based on the latest development stage of fifth-generation BMW eDrive technology. It consists of four modules with 72 battery cells each and three modules with twelve cells each. Thanks to a clever and model-specific arrangement of the modules, the high-voltage battery has a particularly flat design. It can therefore be arranged in the underbody of the BMW i5 to save space. The space available for the occupants thus corresponds exactly to the capacities of the petrol and diesel engine variants of the new BMW 5 Series Sedan. The high-voltage battery of the BMW i5 combines its compact dimensions with a high energy density. It provides a usable energy content of 81.2 kWh. In conjunction with the high efficiency of its electric motors, this results in long-distance ranges for both model variants of the BMW i5. The BMW i5 M60 xDrive achieves a range of 455 to 516 kilometers in the WLTP test cycle. The corresponding figures for the BMW i5 eDrive40 are 498 to 582 kilometers according to the WLTP.
