BMW Hybrid repeated battery failure

Again, the “worst of both worlds” applies to the 2018 BMW G30 eDrive Hybrid, whose complete battery pack is so worn out that repair isn’t feasible without replacing all modules. This vehicle has only covered 150,000 km and first error popped up at 104,000 km that battery is in defect immediately after warranty end, yet it requires a new 9 kWh battery pack costing €11,000 with tax and labor. Despite active thermal control, the cells have degraded and inflated under high current rates, where a small battery supports a large power-train. Each kilometer driven in EV mode damages the battery pack four times faster than the larger battery packs found in full EVs. Hybrids are truly unsustainable and cannot be a part of any eMobility narratives. So, in addition to the pollution from the fossil engine, oil changes, and other maintenance, you also have waste production from poorly designed weak battery systems.

Problem is not withinn quality of cells but the design of the system. Even if you integrate highest quality cells from future year 2155, this system will fail due semifinished design. Small cells with small current rate and capacity cant support heavy powertrain system too long. Charge and discharge cycles of 2000 will wear out in 50,000 and 100,000km. So you understand why it has only 100k warranty on battery pack. BMW is one of the worst Hybrid systems we have ever seen and they are mostly filling our inbox with repair requests.
