Zytek, in conjunction with Lithium Technology Corporation (LTC), has launched a demonstration diesel-electric plug-in hybrid version of a smart for four in London.
The lithium-ion battery pack from LTC subsidiary GAIA Akkumulatorenwerke can be charged by either the internal combustion engine (ICE) and by regenerative braking or by household mains (plug-in hybrid). The vehicle has a fuel economy of more than 84 mpg Imp. (3.36 l/100km or about 70 mpg US) and an all-electric range of 20 miles.
The battery pack has an output of 288 V, a capacity of 7.5 Ah (or about 2.2 kWh of energy) and a capability to deliver 25 kW of power.
Zytek was awarded £1.8 million (US$3.6 million) by the Energy Saving Trust to develop the new HEV. (Earlier post.) The vehicle utilizes a hybrid power train based on a 1.5-liter, 3-cylinder turbocharged diesel engine coupled with two high-efficiency permanent-magnet electric motors. This car is part of the “Ultra Low Carbon Car Challenge” project that is supported by the Energy Saving Trust.
The vehicle has combined technology developed by LTC, Zytek and I+ME for an advanced Battery Management System (BMS). The system is equipped with additional safety features to control the charging of the battery from the mains. The BMS has been designed to communicate with the vehicles’ energy management system to ensure enhanced efficiency and control.
The combination of LTC’s advanced battery system and Zytek’s innovative hybrid drive train, demonstrates a positive step forward in plug in hybrid technology that is simply applied to any OEM platform, as the system is scaleable and transportable. —Steve Tremble, Zytek sales and marketing director
Rest In Peace, old friend, your work is finished.......
If you want on or off the DIESEL "KNOCK" LIST just FReepmail me........
This is a fairly HIGH VOLUME ping list on some days......
"The vehicle has a fuel economy of more than 84 mpg Imp. (3.36 l/100km or about 70 mpg US) and an all-electric range of 20 miles."
The mileage is badly understated, if "all-electric range" is treated separately. That's the whole point of moving to a plug-in hybrid, starting off with a full charge to boost the fuel efficiency. They should use a calculation based upon total miles driven on a tank of fuel, just like any other vehicle, to derive a mileage figure.
An ice scraper might be a necessary assessory to clean off a big enough spot on the windshield so the driver can see if he is still on the road.
7.5AH? that is nothing.
An electric scooter for 7 year old kids have a 12 AH battery in them.
12V*12A=144W/Hr
7.5 AH at 288V. I doubt the scooter stores 2.2 kWh.
I would guess you 12 AH battery is 6, maybe 12 Volts: 0.07 or 0.14 kWh
The article doesn't say but the discussion below says about 33 HP.
With electric drive and a very light vehicle, 33 HP would be plenty. Internal combustion engines are limitted by their torque output at low RMP, electric give you about the same torque at all speeds.
For average driving this would give you about the same experience as a 150 HP internal combustion engine, where you would miss the HP is on the highway, depending on the air resistence, 33 hp would probably limit you to about 80 MPH.
0-60 in 3 days.
For city driving, it would be pretty useful.
The article says the battery holds 2.2 KWH (kilowatt hours)
I don't believe it a addresses motor size.
If you discharge the battery in one minute, you have about 200 HP
Sounds like a major breakthough - batteries that will go up to 20 miles.
Let's just make the thing steam powered, and be done liquid fuels altogether. The 20 mile electric range ought to be enough to get a boiler running.
Can I have a $3.6 million research grant now? Where's the application.
Hehehe, I climbed a hill once in my old car with just the starter, who knows how far I would have got on flat land.....
3 HP over 1 hour is roughly the same energy as 200 HP over 1 minute.
100 watts x 10 minutes equals 1000 watts for 1 minute.
The value they give is an energy value (kWH) not a power value kW.
2.2 kWH will give you about 3 HP for an hour, 200 HP for about a minute or about 12,000 HP for about a second.
Energy (kWH) = power (kW or HP) x time.
