Mahle Opens Second European Auto Battery Development Center

Automotive supplier Mahle Powertrain, intending to boost its battery-development capabilities, opens a second evaluation center in Europe.

The company now provides what it calls a cutting-edge facility in Stuttgart, Germany, aimed squarely at European automakers' requirements for battery-electric-vehicle products.

The facility covers more than 4,265 sq.-ft (1,300 sq.-m) and claims to be able to handle all aspects of battery development, from initial prototyping through to small-scale production and spanning the needs of mobility products from small e-bikes to large electric trucks. This center complements Mahle Powertrain’s U.K. battery development facility set up last year at the company’s Northampton site. It features a fully-featured prototype shop that includes a dual-robot laser welding station capable of handling active high-voltage battery modules.

There’s also a comprehensive test department capable of assessing low- and high-voltage packs up to a maximum of 1,200V, 2,000-amp or 550 kW; incorporating two climatic chambers that operate from ‑40°C to +90°C (-40°F to 194°F) for a full scope of aging, electrical and thermal tests. The facility can also replicate simulated driving cycles in harsh environments, while self-extinguishing workbenches and water drop tanks maintain safety standards.

Simon Reader, Mahle Powertrain’s managing director, says: “In response to growing demand for our expertise in the design, development, testing and optimization of batteries for electric vehicles, we’re delighted to be opening another new facility to support our clients within the European automotive industry. The center is up and running, having completed a number of projects for OEM partners. We have designed the facility with future expansion in mind, with additional services and increased capacity already in the planning stages.”
