Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.

VW and partner SAIC start building $2.5B Audi plant in China

BEIJING — Volkswagen AG's China joint venture with SAIC Motor Corp has started building a $2.5 billion new energy vehicle (NEV) plant in Shanghai, which will make VW's luxury Audi brand cars, a possible first for the venture. The new plant is a key step for Audi to diversify production of its cars in the world's largest car market from its long-standing local partner, China FAW Group Corp. This shift has been delayed amid resistance from local dealers. SAIC Volkswagen said the new plant would have an annual capacity to make 300,000 cars and begin production from 2020. Audi sold 481,387 vehicles in China from January to September this year. The announcement comes the same week Tesla secured a Shanghai location for a Gigafactory battery plant to serve the Chinese market. Audi unveiled the plan to bolster ties with SAIC in late 2016. Earlier this year, the Germany luxury carmaker bought a 1 percent stake in the SAIC Volkswagen venture, paving the way for the joint venture to produce and sell Audi cars. Volkswagen currently gets a larger proportion of the proceeds from the 50-50 tie-up with SAIC than from its 40 percent stake in the venture with FAW. SAIC Volkswagen said in a statement on Friday the plant would cost 17 billion yuan ($2.5 billion) and would make VW and Skoda models as well as Audi cars. It will help VW tap China's fast-growing market for NEVs, a category comprising electric battery cars and plug-in electric hybrid vehicles.
