Audi inaugurates high-voltage battery project house; Panasonic supplying cells

Audi has opened its high-voltage battery project house in Gaimersheim near Ingolstadt. In this competence center, Development, Production and partner companies are working together to construct prototypes. Alongside the production of prototypes, future small-series production is an option.

The project house for the high-voltage battery technology is located two kilometers from the Ingolstadt plant. Around 100 electronics experts newly hired by Audi specifically for this project work at the facility, which covers 3,500 square meters. Panasonic is a key external partner and is responsible for supplying the battery cells. The basic concept behind this competence center is to promote close collaboration between all the disciplines involved in high-voltage technology.

The key areas of focus of the high-voltage battery project house include:

  • The high-voltage (HV) testing area: testing of HV batteries at cell, module and system level;

  • The battery pilot plant facility: prototyping and small-series production of HV battery systems;

  • The design and development of own hardware and software for all components; and

  • The development and manufacture of batteries for the Audi R8 e-tron and all Audi A1 e-tron fleet batteries.

BFFT Gesellschaft für Fahrzeugtechnik mbH was responsible for the detailed planning of the high-voltage battery project house. Particular attention was paid to safety in terms of using the sensitive equipment. Construction began in April 2010 and was completed in May this year.

The new high-voltage battery project house is another major step toward electric mobility for our company. Here we are building up important development and manufacturing expertise for high-voltage batteries with a view to future model series. At the same time, we are ensuring that they meet Audi’s exacting quality requirements.

The name “Audi e-tron” is the Audi brand name for electric mobility. Audi’s aim is to offer an e-tron model in every segment by 2020.



This is an important step that Toyota took 12+ years ago.


What exactly is a high-voltage battery? And overall what advantage this system brings so that Audi is more focused on the HV system than the battery production itself?


Hey ghis:
The systems in electric cars run at 400v, as against the 12v for a lead acid starter motor and ancilliaries.


@ Hey_ghis:
A typical lead acid battery is comprised of six cells at 2 V / cell. The Ah rating is determined by the size of the cells.
Lithium ion cells, depending on the applied chemistry, typically have a nominal voltage of 3.6 V. Different forms and sizes determine the cell Ah rating. E.g cylindrical form or Pouch form (gel or polymere).
100 cells switched in series total to 360 volts. Series switching increases the voltage and parallel switching, the capacity / energy density of the complete battery.


At least Audi/Porsche/VW are getting in the game. As cost of petrol continues to rise - never stopping at a gas station again looks mighty interesting.
