BMW Gen5 Battery System

The current batch of electric vehicles built on the BMW Gen5 Battery System. This design needs to survive until BMW swap to the Gen 6 design in 2025.

The battery packs in the BEV and PHEV applications across SUV and Sedan platforms uses prismatic cells from Samsung SDI and CATL in a number of sizes. The modular approach is designed for repair and 2nd life.

An example of this BMW Gen5 battery system design is the battery pack in the ix3.

2021 iX3 80kWh

This is an OK performance, the Tesla Model Y 4680 pack is at 161Wh/kg. The 2021 Tesla Model 3 21700 based pack is at 171Wh/kg and 860W10s/kg.

Hence appears that BMW is playing catchup with the Gen5 battery pack design.

BMW Group has partnered with German recycling specialist Duesenfeld to establish a method that can achieve a recycling rate of up to 96% of the materials –including graphite and electrolytes.
