BMW 740e / 745e hybrid battery
The BMW 740e and later 745e belong to the G11/G12 7 Series plug-in hybrid family. Model years and versions can use different battery layouts, so the VIN is essential for correct identification.
BMW 740e / 745e
On 7 Series hybrid models, an HV battery problem can affect not only electric range but also drive-mode availability and overall hybrid-system operation. Diagnostics should cover fault codes, section voltages and control-unit communication.
Battery solution for this model
For supported configurations we can prepare a new module solution and workshop information. Compatibility is not assumed from the 740e or 745e badge alone — it is confirmed from VIN and battery data.
For this model we confirm the configuration first. Not every pack uses the same 16S1P module, so a module offer is prepared only after VIN verification.
When to check the HV battery
The symptoms below are reasons to run diagnostics. Not every symptom proves the battery itself is faulty, so fault codes and BMS data should be checked before purchasing parts.
Logistics and installation in Poland
Warsaw stock and delivery time are confirmed with each enquiry because inventory changes. When a product is shipped from China, we prepare a logistics option suitable for high-voltage batteries. We can work with the customer’s independent workshop and provide installation information.
