Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Daimler, Toyota, BMW to lead $10-billion hydrogen investment

Daimler, BMW, and Toyota are leading a group of 13 companies pledging to invest more than $10 billion during the next five years to spur enough infrastructure-building and technology advancements to get more of the general public to buy hydrogen fuel-cell vehicles. The automakers, which also include Honda and Hyundai, as well as companies such as Shell, AirLiquide, Linde Group, and Total SA, are part of what they're calling the Hydrogen Council. The group made its announcement in Davos, Switzerland, on Tuesday. The Hydrogen Council will pledge to accelerate its rate of hydrogen-related investments, which currently stand at about $1.5 billion annually. The coalition says its work represents a continuation of the 2015 Paris Agreement, in which many of the companies agreed to address the issue of climate change. The group says that hydrogen, which emits water vapor when used in fuel-cell vehicles, "can play an important role in the transition to a clean, low-carbon, energy system." The Hydrogen Council also vowed to push global governments to accelerate public investment in hydrogen-related infrastructure. Relative to other drivetrain technologies, hydrogen fuel-cell vehicles are in their relative infancy in terms of adoption because of the high cost of both building fuel cell vehicles and setting up a hydrogen-refueling infrastructure. Toyota is the only automaker that sells a production fuel-cell vehicle in the US. The Japanese company, which introduced its Mirai domestically in late 2015, sold 1,034 of them in the US last year. Daimler subsidiary, Mercedes-Benz, used Tuesday's announcement to remind people that it would start selling its GLC plug-in hydrogen fuel-cell crossover this year. There are only 33 publicly accessible hydrogen refueling stations in the US, including 30 in California, and one each in Connecticut, Massachusetts, and South Carolina, according to the US Department of Energy. By comparison, there are more than 15,000 electric-vehicle charging stations with almost 40,000 outlets in the US.

Audi, BMW, Daimler buy Nokia's Here digital mapping business

The fight for control of Nokia's Here digital mapping service appears to have drawn to a close as a consortium of German automakers has announced a deal to jointly acquire the business from the Finnish telecom giant. As anticipated, ownership in Here will now be taken over jointly by Audi, BMW, and Daimler, beating out reported rivals bids from the likes of Apple and Uber. Here is one of the largest and most advanced digital mapping and location systems. It started out in Chicago in 1986 as Navteq before Nokia acquired it in 2007, and is now slated to change ownership again. The cloud-based service maintains high-definition digital maps for nearly 200 countries and supports over 50 languages, gathering data from users to update the data continuously. Rather than transition the service into their own proprietary technology, however, the automakers insist that it will remain open "to all customers from the automotive industry and other sectors." Ownership will be shared equally between the three companies, with "none of them seek[ing] to acquire a majority interest" in Here. For another, Here's management is promised to remain independent, and "the consortium will not interfere into operational business." Though the purchase price has not been disclosed, it is rumored to be worth in the neighborhood of $2.7 billion. Assuming it passes regulatory approval, the acquisition is slated to be completed in the first quarter of next year. The German automakers anticipate implementing the service to provide connected vehicles with accurate, up-to-date information on road and other conditions. Examples it outlines include warning other drivers of icy conditions based on outside temperature and ABS activation. It could also warn drivers of impending traffic jams, or even guide traffic through green lights in an urban environment. In the future, the highly detailed maps are envisioned to enable fully automated driving as well.
