Als jouw auto aan het laden is en je moet dringend weg, dan zal ik gaan tanken en ik vertrek terwijl jij lekker verder laadt
Er zijn nu al Lithium-titaan accu´s in E-auto´s die onder 10 minuten 95 % opgeladen kunnen zijn door een fast charge unit, die worden wslk enkel in "E-stations" voorzien, want die hebben meerdere Kilovolts nodig; dus daar zijn al mogelijkheden voor het klassieke tanken.

Off-Board High-Power 250KW Charger: Under 10 min. to 95% SOC
* Ref zie onderaan: ref gevonden van "fast charger units", ttz een idee van oplaadtijd naargelang x-kW per fast charge unit
Voor meerdere uren-oplading: thuis mogelijk (400 V), of een 3-fazige power supply kan men ook meenemen en die ergens op het evtl voorziene net in te pluggen (tijdens lunch /diner buitenshuis ?).
Langere oplading: gewoon E-auto thuis inpluggen in het stopcontact.
Enkele kilovolts voorzien is simpel en héél veilig vergeleken met de gevaarlijke waterstofdistributie.
(treinen rijden er ook op...)Opmerking vooraf : het gaat niet om de auto, maar om de evolutie van de Lithium-accu´s.

Q. How long does it take to charge the Lightning?
A. There are likely to be three options:
1. - Overnight using a domestic power supply
2. - a couple of hours using a 3 phase power supply
3. - and just 10 minutes using a fast charge unit.
Q. How will the Lightning be charged away from home?
A. Standard single phase home type power source can be used to charge overnight and is available just about anywhere by using the onboard charger.
For a fast charge a 3 phase power supply is required and with the interest in electric powered vehicles increasing significantly, more high power charging stations will be installed.
Most garage forecourt and industrial areas already have this level of high power source available and therefore can be fitted with a universal charging station.
Q. How does the Lightning charge its battery system?
A. The Lightning has a built in battery charging and control system. Simply plug the car's charging lead into your home's electric power point and you'll soon be charged and ready for the next journey. The lead is 12 feet long (optional 20 foot extension cable available). The electronics take care of various power sources that it can receive power from. It's as simple as that! There are a number of different sources that can be utilised with this cable and charging times can vary depending on the state of the batteries and also the power source chosen.
Q. Do the batteries require any cooling or heating and will the car operate in low winter temperatures?
A. The NanoSafe™ batteries are designed to be used in vehicles and hostile environments and will work in temperatures between 75°C and minus 30°C. Unlike standard Lithium-Ion batteries in electric vehicles these don't need to be kept cool when charged/used or heated to get them to perform in sub zero temperatures.
Q. Are the batteries like the "laptop variety" of small cells, thousands of which are used for the battery pack?
A. No, each NanoSafe™ battery unit is about the size of a large car battery and only thirty such units make up a complete battery pack. These are situated in the car to give the desired ultra low “centre of gravity” and optimum weight distribution both front and rear
Q. Do the batteries take up the entire boot and bonnet space?
A. As there's no fuel tank, the Lightning GT offers plenty of boot space with golf clubs no problem! The batteries are only 9” high ensuring additional bonnet space is also available. Locating the batteries in the optimum position allows the Lightning to have ‘designed-in’ weight distribution and low roll centres. This, combined with the high technology chassis, will achieve excellent road holding performance dynamics.

The Lightning has no large fuel tank. Instead it incorporates a state of the art NanoSafe™ battery system. NanoSafe™ batteries use nano titanate materials instead of graphite which makes them far more thermally stable – there are no toxics or heavy metals used in NanoSafe™ batteries.
Nog 5 of meer jaar geduld, en het wordt 5 minuten, gewoon aan het klassieke E-station
(roken en gsm-en niet verboden), wat gescheiden naast een gewoon tankstation
Nog een beetje reklame, jullie willen toch info ?

NanoSafe™Until now, battery technology has hindered electric vehicle innovation. In 2000, US company Altairnano Inc. established a research programme to create an ultra safe, high power battery using cutting-edge Nanotechnology. The result of their hard work is the NanoSafe™ battery.
SAFER - NanoSafe™ batteries use nano titanate materials instead of graphite which makes them far more thermally stable - there are no toxics or heavy metals used in NanoSafe™ batteries.
LONGER-LASTING - NanoSafe™ batteries have a life expectancy of 12+ years, versus the 3-5 year usable life of other batteries. NanoSafe™ can retain up to 85% charge capacity after 15,000 charges.
FASTER CHARGE - NanoSafe™ batteries can be recharged in approximately 10 minutes, rather than the hours required by many other rechargeable batteries.
MORE POWERFUL - With instantaneous power even at extreme temperatures, NanoSafe™ batteries deliver power per unit weight and unit volume several times that of conventional Lithium-Ion batteries.
NanoSafe™ is the power supply choice of Phoenix Motorcars for their Sport Utility Truck. www.phoenixmotorcars.com
NanoSafe™ has also powered the world record beating EV dragster driven by Dennis Berube in Tucson Arizona on December 30th 2007, during which he achieved a top speed of over 160mph in under 8 seconds.

Men kan deze goedkope zware SUV (2200 kg) natuurlijk niet met die lichte sportwagen Lightning GT (1220 kg) vergelijken ondanks identieke batterijen, het verbruik van de aerodynamischere en lichtere sportwagen is veel lager, zie het rijbereik van 188 miles tegen 100 miles, daarbij heeft de GT veel betere techniek o.a. het regeneratief opladen vd accu´s tijdens het remmen:
Q. How does the regenerative braking work?
A. When you brake, the car's kinetic energy is converted to heat through friction - throwing away the energy that was previously used to accelerate the car. In city driving, about 30 percent of a typical car's engine output is lost to braking. This proportion drops to almost zero in highway driving, where braking is much less frequent.
An electric vehicle uses an electric motor to create torque to drive its wheels. When an electric vehicle is approaching a stop light, it doesn't create friction and useless heat in order to slow down. Instead it reverses its electric motor turning it into an electric generator, creating electricity which is fed back into the battery and stored for future use. In fact any time an electric vehicle decelerates it causes the system to use the vehicle’s momentum to generate electricity.
