'Boozer' EV sets 1,000 miles-plus record on single charge
August 17, 2011 by Nancy Owano 
(PhysOrg.com) -- An experimental electric vehicle called "Schluckspecht" ("boozer," or "tippler" in German) has set the record for achieving the longest drive in a battery-powered vehicle on a single battery charge. Its record-breaking distance was 1,013.8 miles (1,631.5 km). The trip lasted 36 hours and 12 minutes. The Schluckspecht E, as the winning machine is called, was developed at Germany’s University of Applied Sciences, Offenburg, in collaboration with other academic groups. The test drive took place in Boxberg at the Bosch corporate test track, where a team of four drivers made the trip, as they took turns navigating over the long stretch of hours.
While nothing beats a world record, this is not the first time Team Schluckspecht has made the EV design scene sit up and take notice. They also won attention at the South African Solar Challenge last year, driving 389 miles on a single charge.
The team was founded in 1998. Their name Schluckspecht was taken because of their first car, a prototype gasoline vehicle that devoured too much fuel to be effective in competitions. After successive models with successive improvements, the team switched its technology focus.
The aerodynamic design and weight efficiencies of the vehicle are singled out as reasons for the team’s success.
Those features are considered important because electric cars have tried to resolve the hurdle of range. Attempts have included charging station networks, and special range-extending engines, but the Schluckspecht team came up with a more optimal design to address range.
They traded off comfort, being a single-seat experimental car, for reduced weight. The designers made use of two wheel-mounted hub-motors. There was no need to accommodate an internal engine or transmission. Their design represents a lighter vehicle with an efficient battery management system which evenly divides the load among 14 individual lithium-cobalt battery packs.
The Schluckspecht victory beats a previous record of 1,003 km (623.23 miles) held by the Japan Electric Vehicle Club in May 2010. The Schluckspecht E achieved an average speed of 45 km/h (28 mph), while the Japan Electric Vehicle Club’s Daihatsu Mira averaged 40 km/h (25 mph) on a single charge. The Japan club's car achieved 1,003 km, approximately 623 miles, on a single charge, in a 27.5-hour timeframe.

Better battery management, good aerodynamics and dumping engineering concepts that make sense in combustion driven cars but not in electric ones seem strategies that still hold a lot of potential.
If they pare it down so this car could go 500km on one charge with an average speed of 120km/h then I'm sold.

I'm not.
It's one thing to go 28 mph in a car made out of bicycle tubing and glass fiber. It would be completely mad to take that thing up to highway speeds and expect that it stays on the road come wind or rain.

I wonder how you would feel after doing 1000 miles on your bike at 28 miles per hour. I don't think even Armstrong could have done that even on flat ground. And I don't think there is anywhere on earth with a 1000 mile long downhill route...
The whole point of this exercise is to show what CAN be done if you are willing to do it, and have the bucks. The design and build may have cost a mil and a half but that is because it is a one off machine. These kind of developments have a habit of finding their way to real autos in due time. I want to see solar cells in paint jobs to supplement electric power. That way, you park outdoors and charge up your car while at work. 8 hours later, you maybe have enough charge to get home with just the energy stored in the daytime.
Who knows what developments will happen in the future, for instance, room temperature superconductors. That would change the game!

The optimized one factor. That's how you do these kinds of things: optimize one factor at a time (per group working on it). Then you start bringing together what all the other groups do.
Im not sure that's sensible. Even if you had 100% efficient solar cells then the entire surface area of a car at midday under optimal sunshine conditions (no houses or other obstructions around you) would get you 1-2kW extra.
In most other conditions the added energy would be negligible.

Actually, that's just the thing about velomobiles. A human on a bicycle is aerodynamically like a barn door. Velomobiles are highly efficient. A single 12 volt car battery has the energy to take you up to 100 miles at 25 mph in one. (but don't try: deep discharge kills the battery!)

If you are in a good physical condition, you can quite happily produce about 200 Watts (.27HP) continuously for a day.
The problem of velomobiles is, that there's no luxury in them. They're small, fragile, hot/cold depending on the weather, and have little carrying capacity beyond the driver.

A car travelling at 100Kmh for 100Km - vs. - a car travelling at 50Kmh for 100Kmh.
OK factoring in drag and the cube root as speed doubles - NO ONE and I mean NO ONE - except for me has ever factored in the fact that the car doing 50KMH has it's engine running for twice as long - as the car doing 100KMH.
So in simple terms a car doing 100Kmh may get 10Km to the liter of fuel, and the car doing 50KMH, may get 20KHM to the liter of fuel - but - I think I may have gotten myself stuck here..
But that is OK.
Because I know what I mean.
The engine is running 2 X as long, over a given distance (in a frictionless engine) at 1/4 the power.

You mean except for the government people putting up signs for 'reduced speed areas' in order to conserve fuel? And they thought of that about 25 years ago?
Yes..You are right. No one (with the exception everyone but you) has thought of that.
How does that saying go?

Then you add proper brakes, proper wheels, proper headlights and signals, a proper frame with crumple zones, proper seats and airbags; you triple the weight and even more the rolling resistance, and have to increase the number of batteries to compensate which further increases the weight and size of the vehicle.
Then you end up with a car that does "100 miles" under ideal conditions.
Nothing solved, nothing gained.
