The high-voltage battery for the fifth-generation BMW eDrive was developed from the ground up with pioneering new battery cell technology. The high-voltage batteries’ output and energy content can be flexibly scaled for use in different vehicle concepts and segments.
The BMW Group has more than ten years of deep in-house expertise developing battery cells. All know-how flows into precise specifications for battery cells to then be manufactured externally. Systematic research and development efforts not only steadily enhance performance and energy density, but can also continuously improve all relevant battery cell characteristics. Considering all relevant aspects as a whole – especially durability and safety, BMW high-voltage batteries represent the best that can be achieved today. At the same time, the newest battery generation has also been able to reduce the amount of the cobalt used as a raw material by another two thirds. Compared to the battery cells widely used by the BMW Group in its fully-electric vehicles in the past, the battery’s gravimetric energy density has been improved by about 20 percent at cell level in the BMW iX3. The BMW Group is sourcing its own cobalt and lithium for the first time and supplying these raw materials to its battery cell producers.
As a leader in sustainability, the BMW Group has also reached a contractual agreement with its cell manufacturers that they will only use green power to produce fifth-generation battery cells.
The expanded High-Voltage Battery Centre is the first location in the BMW Group production network to manufacture fifth-generation high-voltage batteries. At the same time, the Competence Centre for E-Drive Production in Dingolfing is also gearing up to produce the new fifth-generation high-voltage batteries. These will be installed in additional products, such as the BMW iNEXT and the BMW i4, starting next year. By producing high-voltage batteries where they are needed, the company is able to minimise transportation and thus contributes to sustainability.
The BBA Brilliance Automotive joint venture was founded in 2003 and has become one of the most successful premium automobile manufacturers in China in recent years, encompassing production and sales of BMW automobiles in China, as well as local development tasks. In 2019, the BBA automotive plants in Tiexi and Dadong produced over 530,000 vehicles for the Chinese market – an increase of more than 9% year-on-year. Maximum capacity at the two plants will reach 650,000 units per year over the coming years.
