EVEVEV

Demonstration adaptation project : Demonstrating shared community use of a sustainably fuelled vehicle in a rural area.

Location:  Based in Aviemore, but available and widely demonstrated around the Badenoch & Strathspey (B&S) area, Scotland

Official launch 16th November 2009, Kingussie High School, Scotland

The project will demonstrate the practical aspects of the rural use of a community shared, used and administered Electric Vehicle (EV) in Cairngorms National Park (CNP). Based in Aviemore, but available and widely demonstrated around the Badenoch & Strathspey (B&S) area, it will be available to residents in the locality through the Badenoch & Strathspey Community Transport Company (B&SCTC). The project will run from January 2009 until February 2011.

B&S is 1,600sqkm in area and has approximately 12,000 residents spread over several small towns, the biggest being Aviemore. There are 1.4million visitors a year to the Park, around 1 million to B&S.

The area is remote and rural, but benefits from a mainline train link to Inverness (40 Minutes by train) and Edinburgh & Glasgow (both around 3 hours away). There are also inter-city buses and a local bus network to some villages. Most people arrive by, and rely on, a car.

The area, like many rural areas, will be affected by changes to the environment and economy caused by climate change and adaptation will be required sooner rather than later to minimise the impacts. With the distances involved in living, working and visiting the Park, transport is a vital part of life. It is one that is becoming more expensive, and being increasingly recognised as damaging to the local and wider environment. Currently fossil fuels are used to power trains, buses and road vehicles. It is expected that both a demand for better environmental protection and economics will slowly drive a shift from fossil fuel for transport use, but adaptation to new forms of energy is urgently required.

Fossil fuels are supplied globally on a large scale and thus their supply is vulnerable to disruption – climate change impacts are very likely to disrupt global supplies either directly through extreme weather events or indirectly through civil unrest as conflicts arise over limited resources.

One solution is own an to move to an electric vehicle (EV). This can be powered in a number of ways all of them more efficiently than an Internal Combustion Engine (ICE). Power can come from green sources via the National Grid, or locally produced renewable energy. It can be refuelled at home or work reducing the need for vulnerable fuel infrastructure, fuel supply & transportation. Cost is far lower at around 1/10th of the cost of running an ICE allowing residents and visitors to adapt to Climate Change through reducing the percentage of their budgets on transportation.

EVThe impacts of climate change, particularly extreme weather events are likely to increasingly affect travelling conditions. The current dependence on, and high ownership of vehicles has already resulted in a number of recent grid lock or traffic jam situations on main routes within the Highlands as a result of recent extreme weather events e.g. damage to bridges at  river crossings.

One solution to this is to move away from this high car ownership mentality and to look at sharing the use of a car within a community. In this project the Electric Vehicle will be used by a number of volunteer drivers on a system administered by the Aviemore by the Badenoch & Strathspey Community Transport Company (B&SCTC). They already administer 70 volunteer drivers who use their own cars to give lifts to mainly elderly residents. B&SCTC will lend the EV out to its volunteers for their use replacing the use of ICE cars. The EV will be shown to visitors and residents at local Games and Shows.

The EV will be bought and converted by a specialist engineer based in Wales, John Lilley of Dragon Electric Vehicles. Perth College – UHI will purchase the EV and be the owner for the duration of the project, and in February 2011 it will be sold

There is currently no EV use or re-charge network in the area, and there is a knowledge gap in what EVs can achieve. Lack of knowledge is affecting people’s capacity to make informed adaptation decisions in response to Climate Change. In the UK, EV current activity is urban-based. With the improvement in range of EVs it is now possible to demonstrate their use in remote, rural areas. The project will aim to raise awareness of electric vehicles, as well as other sustainable fuels and promote car sharing by moving the EV around B&S to showcase it in different villages. It will also be widely marketed at local Highland Games and Shows, and taken to schools and relevant organisations. The car will be branded with the Clim-ATIC and project partner logos. A media strategy will be developed to maximise publicity.

The project will begin to build a network of EV recharge points, putting in the infrastructure to encourage new EV owners and visiting EVs. These Elektrobay points will re-fuel EVs via a 13amp connection. The project’s EV will also have access to outdoor recharge points including a fast-charge facility. This is important, as the range is 140km, or around 3-4 hours driving. To get the best use from the vehicle it will be rechargeable over a lunchtime for extended use. In addition the project will purchase a trailer and a small wind turbine that will be able to contribute to the charging of the EV when parked. It is recognised that this element of the project will be unable to fully meet the charging demands ,but depending of wind conditions and charging time the demonstration of such a piece of equipment with give added value to this project. It will also certainly help raid eth profile of the EV at events.

The project will demonstrate the positive aspects of rural EV ownership and operation. This is easily transferable across other rural areas and does not rely on a National Park situation. An important part of the project is promoting transnational cooperation in getting more rural EVs and visits will be sought and encouraged from other countries. Although the other two Clim-ATIC transport themed demonstration projects are not EV based, visits and links to other EV projects in partner countries will be contacted.

The EV fuel costs will be covered by payments made through B&SCTC to their drivers. A small amount of re-charging will be required for marketing which will be absorbed into the budget (it costs under 10% of an ICE vehicle to fuel).

The total cost of the project for the full 2 years will be around £77,000. The Clim-ATIC project will be providing up to £35,000 in staff time and project management costs, some travel costs, and vehicle purchase and conversion costs. Other funding has been secured from the Scottish Government's Climate Challenge Fund and other energy related organisations to meet the remaining costs.

Driving the Clim-ATIC EV

Electric cars are four or five times more energy efficient than petrol cars, and when powered by renewable electricity use less than a tenth of the energy that normal cars do. (This is mainly due to the energy of manufacture.) They are very cheap to run, but have limitations in their range, largely due to the amount of power that can be stored in the car’s battery. The amount of energy stored in a typical car’s petrol tank is 500kWh. In the Dragon electric Astra, using some of the most advanced battery technology available, the battery holds 30kWh. This is sufficient for a range of over 100 miles when driven gently, but it will have much less range if driven hard, on hilly terrain, or when towing a trailer.
 
Electric cars are very different to normal cars. An internal combustion engined car (ICE car) is most efficient when driven at 45 – 55mph, and is less efficient at slower and faster speeds. An electric car is most efficient at low speeds and can achieve a maximum range at a steady speed of about 35mph. At speeds above 45 mph, power consumption increases rapidly and the range per charge will reduce. It takes a very different driving style to maximize the range of an electric vehicle, and the section on driving style will give you some hints on how to drive it for maximum efficiency.
 
Safety
 
The Dragon Electric Astra has a petrol tank for use by the car’s petrol space heater. Like normal cars, proper caution should be taken in filling the tank. Any petrol spills or smells should be investigated and cured immediately.
 
The electric battery in the car is exceptionally powerful. The electrical wiring connections should not be approached except by trained personnel. Do not remove the boot floor or open the bonnet for inspection without first removing any watches or jewellery or any other metal objects and wearing face and eye protection. Do not use any uninsulated metal tools anywhere near the batteries. The battery can produce instantaneous power of half a megawatt. Touching the battery terminals with anything metal could cause INSTANT EXPLOSIVE VAPOURISATION. Leave any inspection or maintenance to trained personnel.
 
Instruments
 
All the switches and instruments work exactly the same as a normal Astra except the air conditioning. This has been removed from the car because air conditioning uses a lot of power, and would significantly reduce the range of the car.
 
The alternator and engine stall warning lights will remain on as these are not needed in the electric car.
 
An additional LED meter has been provided to give an indication of the state of charge of the battery. When the battery is full, all the lights will be on. When running along, the green lights indicate the battery is being used efficiently, and you will achieve a good range. When the car is being driven hard, the green lights will extinguish and the amber lights indicate an intermediate battery condition when driving. When only the red lights are on whilst driving, the charge in the battery is getting low, and it is best to be very gentle with the throttle and find somewhere to recharge. If only the red lights are on, the battery will age a little more rapidly, so they will have a shorter life. Try not to let all the lights extinguish, this will age the battery much more quickly.
 
When the charge is very low, the controller will not operate at high throttle settings, and will only allow a small current from the battery. In this way the very expensive battery is protected from serious damage. It will mean, however than the car will be very slow. This is the time to creep to your nearest charging point in first gear!
 
Driving Style
 
The Astra conversion by Dragon Electric Vehicles can be driven exactly like any normal manual gearbox car, but the higher gears (4th and 5th) should not be used. The main difference is the lack of noise and vibration, which can be quite confusing to begin with. You will also be able to hear noises that you would normally not notice – gearbox and tyre noise will be much more audible without an engine to mask them!
 
If you are unfamiliar with driving electric vehicles, you may find it easier to use only second gear, and not use the clutch at all. Starting the vehicle in second gear is very easy except for hill starts, and it is very tractable at any speed from 0 to 50mph in second.
 
Starting Up

The tachometer has an artificial zero of 500rpm, created electronically to ensure all the car’s systems work correctly.  After the ignition is turned on, the rev counter will rise to 1000rpm, then fall to 500rpm, after which the car will accelerate when the throttle is gently depressed. If you use the clutch to pull away from standstill, you will need to rev the car above 500rpm to make sure you have enough torque to pull away in the same way as a normal car. However, being electric, if you prefer, you do not need to use the clutch to pull away from standstill, only to change gears. The car will accelerate quite happily if you put it in gear, release the clutch, and just press the accelerator when you want to move away.

 
Electric cars are most efficient at low speeds, and the maximum range is normally stated at 30 or 35mph. You will need great self control to get the maximum range from the car. This can be most easily achieved by not using anything more than second gear, especially for towing. The use of third gear will give a good performance to keep up with most legal “A” road traffic, but will burn a lot of energy.
 
The electric motor in the Astra has a very different power characteristic to an internal combustion engine. It will pull best at low motor revolutions, but is most efficient at high revolutions - exactly the opposite to a normal car. Thus when driving the car, it is best to keep the motor revving at about 3000rpm. It is best to rev the motor to 4000rpm before changing gear, and if you are cruising, to also keep the revs above 3000rpm. In practice, this means you will almost always be in a lower gear than you would in a petrol or diesel car. Drive the car in first gear to 20mph, second gear to 40mph and third gear if you need to travel at 65mph.
 
Do not use fourth gear for other than very short periods of time. The electric Astra is very powerful for an electric car, and the use of fourth gear will seriously deplete the battery and reduce the range a lot. The use of fifth gear or fourth gear uphill will make both the motor, battery and controller very inefficient, and you will quickly lose power due to overheating.
 
The car will not travel as fast as a normal Astra, and when cruising it is more efficient to select a lower gear at full throttle, than a high gear at part throttle!
 
I would suggest normal gear changes at the following speeds:
 
1st to 2nd …………..20mph
2nd to 3rd …………..40mph
3rd to 4th …………...65mph. Use 4th for short periods only. You will find you will not go much faster anyway!
5th  ………………….No benefit in using 5th gear.
 
Just like a normal car, it is important not to overrev the motor. Taking the motor over the red line can cause damage to the motor, so be sure to select a sufficiently high gear for going down hills – the absence of a screaming motor will not warn you it is revving too fast!
 
You can use the charge indicator to help you drive economically and obtain maximum range from the Astra. When you depress the throttle, lights on the charge indicator will go out. If you try and drive with as few lights out as possible for any given driving situation, you will be using the Astra at its most efficient, and this will increase range and extend the life of the battery.
 
As the battery becomes depleted on your journey, more and more dashboard lights will become extinguished when you depress the throttle. When only red lights are showing on the charge indicator, it is time to start thinking about finding a place to recharge. If you still have some way to go, drive more slowly to prevent the red lights extinguishing altogether.
  
Recharging
 
The battery in the electric Astra is very expensive, but should last a long time if it is looked after properly. If the car is used almost every day, the battery should last eight years if it is charged after it is not much more than half empty. If it is not charged until it is three-quarters empty, the battery is only expected to last for five years. If it is regularly run down further than this, it will significantly shorten the battery life still further.
 
It is therefore important to charge up the battery as often as you can, as full as you can. This will not only extend battery life, it will make sure you have maximum .
range available to you when you need it.
 
The range of the car also depends on the temperature of the battery. In cold weather, heaters keep the battery warm, but only when it is plugged into the mains power. So keep the car plugged into the mains whenever you can, but most importantly in cold weather.
 
Recharging is done through the charger in the boot of the car. The boot is opened and the charging lead passed through the channel in the boot lip, and then plugged into any available domestic 13amp socket or extension lead (as long as it has a full 13amp capacity).
 
Planning your  Journey
 
As electric cars have a limited range, and take a relatively long time to recharge, it is important to plan your journeys in advance, and plug it in for a recharge whenever you can.
 
It is a useful habit to reset the trip meter at the start of each journey when the battery is fully charged. You will soon learn what range you can expect for variations in your driving style and terrain. Weather conditions can also affect the range and performance of an electric car much more than ICE cars. A wet road or a headwind will reduce your range just as going uphill will – always leave a bit of range to spare to make sure you can complete your journey.
 
Charging
 
Whenever you stop, plug it in and leave it to look after itself!
 
It will cost less than 50p per hour to recharge the car even on peak rate electricity.
 
Once fully charged, it will turn itself off and maintain the battery at optimum operating temperature at a cost of about 1p per hour.
 
It is important to fully charge the battery as often as possible. The bulk of the charging gets the power into the battery, but the end of the charging period “balances” the cells in the battery and is very important to maintain good battery life.
 
The charger will normally have a green light lit all the time to indicate that the battery status is good. When the charger is switched on, the yellow charging lamp will also light. When the second yellow charging lamp illuminates, the balancing charge starts, and the red lamps on the top of the charger shows which cells are balanced, and which are still charging. A second green lamp illuminates when the charging is complete.
 
If a red “fault” lamp should light. Turn the charger off and then on again to continue the charging cycle.
 
Heater
 
The Dragon electric Astra has a petrol heater to keep the car warm in cold weather. This heater is very efficient, but, like an ICE car’s heater, it takes a while to warm up. It is a standard Eberspacher unit, common to many trucks for space and water heating, and can be maintained by any of the network of Eberspacher dealers around the U.K.
 
The heater is probably the noisiest part of the car, but operates independently of the motor. Its operation is automatic, and is controlled by the1/0 switch installed on the right hand side of the steering wheel. This means it can be turned on 10-15 minutes before the car is to be driven, so that the occupant can get into a warm, demisted car before the journey is begun!
 
The heater acts independently to the rest of the car, and will turn the car’s heater fan onto position “2” automatically when the water is up to temperature. It will also automatically shut down, and may well continue to operate when the vehicle has ceased being used.
   
Servicing and Maintenance
 
The Astra is a standard production car and the 12v electrics and lights, brakes, tyres, power steering and windscreen washers and wipers are serviceable by any competent garage.
 
Any faults with the battery, and traction power components should be referred to Dragon Electric Vehicles.
