 Daimler Makes Breakthrough in Lithium-Ion Battery Technology
Mercedes S400 Hybrid

Debuting on S 400 Hybrid

Mercedes is preparing to go green in a big way, and now the company has announced they have made a major breakthrough with lithium-ion battery technology. The breakthrough allows the company to become the first manufacturer to succeed in adapting lithium-ion technology for use in automotive applications.

The main advantage lithium-ion batteries offer over conventional nickel-metal batteries are compact dimensions and superior performance. By integrating the batteries into the climate control system, the battery pack operates at optimal temperatures providing a long service life and maximum performance.

Available on the S 400 BlueHYBRID, which will arrive in 2009, the system only consumes 7.9 liters of gasoline per 100 km. CO2 emissions are rated at 190 grams per kilometer, making the S 400 Hybrid the world’s most economical luxury sedan. Power is rated at 220 kW (299 hp) and 375Nm of torque, allowing the hybrid to accelerate from zero to 62mph in 7.3 seconds and reach a top speed of 250km/h (155mph).

The system will also be used in the S 300 BlueTec Hybrid which will maximize fuel efficiency by combining a diesel engine with hybrid technology.

Daimler Makes Breakthrough in Lithium-Ion Battery Technology 

First patented integration of a lithium-ion battery into a series-produced passenger car 
Available in Mercedes-Benz S 400 BlueHYBRID starting in 2009
25 patents for top technology “made in Germany”

Daimler AG has achieved a crucial breakthrough in battery technology. The Stuttgart-based automaker is the world’s first manufacturer to have succeeded in adapting lithium-ion technology to the demanding requirements of automotive applications. Until now, the technology has been used primarily in consumer electronics. The new battery will be used in the series-production S 400 BlueHYBRID beginning next year. This important technology was possible thanks to 25 patents held by Daimler.

Dr. Thomas Weber, member of the Daimler AG Board of Management and responsible for Group Research and Mercedes-Benz Cars Development, says: “What we have here is a groundbreaking key technology that is going to be a decisive factor for the future success of the automotive industry. That is a tribute to our intensive research efforts, which we have been conducting in this area since 1992.”
The engineers’ success is above all a result of the Daimler-developed integration of the lithium-ion battery into the vehicle’s climate control system. This ensures that the battery always works at optimal system temperatures of between 15 and 35°C, which in turn makes it possible for the battery to provide long service life and maximum performance.

The main advantages offered by the newly developed lithium-ion battery are its very compact dimensions and its far superior performance compared to conventional nickel-metal hydride batteries. The weight/power ratio of the entire battery is 1,900 watts per liter (W/L). What’s more, the battery stands out by virtue of its high ampere-hour efficiency, long service life, and great reliability, even at very low temperatures. Its high level of safety is the equal of that provided by today’s auto batteries.

Lithium-ion batteries are ideally suited for use in hybrid vehicles to help reducing fuel consumption and thus also CO2 emissions. At the same time, the Daimler engineers are investigating to what degree this technology can be applied to other vehicle concepts, such as electric and fuel cell-powered cars.

S 400 BlueHYBRID - the world’s most economical luxury sedan

The S 400 BlueHYBRID consumes only 7.9 liters of gasoline per 100 km in the NEDC. This results in very low CO2 emissions of only 190 grams per kilometer, a very low value for this vehicle class and power class, making the S 400 BlueHYBRID the world’s most economical luxury sedan - unrivaled by any gasoline, diesel, or hybrid drive system offered by any competitor.

And S 400 BlueHYBRID drivers will still enjoy impressive performance: combined with the hybrid module, the maximum output is 220 kW/299 hp, and the corresponding maximum torque is 375 Nm. The S 400 BlueHYBRID accelerates from zero to 100 km/h in 7.3 seconds on its way to an electronically limited top speed of 250 km/h.

Even more potential is offered by the combination of clean BlueTec diesel technology with a hybrid module, a duo that is featured in the S 300 BlueTec HYBRID, for example.

they do, Lotus's triflex car runs on methane. And one of the best ways to produce methane is to gather cow fecal matter and let it rot and collect the gases. http://www.truehealth.org/methane.html

i wish they made a car that ran on bullsh*t. There would be an endless supply to go around. I think Mercedes is and always has been the pioneer in engineering with vehicles. Great job with this. Cars are starting to head in the right direction in general. They are made to go from A to B. Some people want to get there faster than others and some want to get there cheaper than others. I think this is a step in the right direction to get you there fast and and cheap and still look good doing it.

they should at least make this technology in the smaller cars first. people that can afford a s-class wouldn't really worry about the mpg. maybe a tree hugger that has lots of money.

great news indeed from an environmental & technological perspective but what is the price premium to own one of these vehicles? looking at it from a financial (and admittedly selfish) perspective, hybrid vehicles are bad investments unless you drive a lot or plan to own your vehicle for a long time. the average cost savings per year would be about $1,200 USD for your typical driver (i.e. 15,000 miles/year with fuel at $3.50/gallon and a gain in efficiency from 18mpg to 30mpg). so over a 5 year period the savings is about $6,000. is it worth it?

Fantastic news. A big step in the right direction. An engine of this size is still more than ultimately I'd like to see in production (hardly necessary). Smaller engine and even lower carbon emissions!

while li-ion batteries in a vehicle are a big step forward, I can't help but wonder. 30mpg? What would have been cooler is a plug in hybrid that gave up to 40 or 50 mpg with the same engine configuration.
