An Introduction To Electric Vehicles
If you are thinking of driving an electric car or van for the first time you are likely to have a lot of questions.
In this introduction we are going to look at the basics, explain the different types of vehicles currently available, and answer some of the most common questions.
Perhaps you are unsure how far you can drive on a single charge? Or how many charging points there are, if electric vehicles will cost more?
This overview will help you get started on a more sustainable form of motoring – it will not only save you money but help the planet at the same time ☺.
Why should I consider an electric or hybrid vehicle?
Plug in vehicles can potentially help us to improve urban air quality and reduce our contribution to global warming. They not only emit much lower C02, NOx and particulates – in the case of pure electric mode, produce zero tail pipe emissions. This offers huge benefits over petrol and diesel powered vehicles – great news for our urban surroundings and the health of everyone living and working in these areas.
Plug in electric vehicles are key to help the UK meet EU targets for urban air quality and the ultra low Emission Zones and Clear Air Zones which are being introduced in 2019
Currently 5 cities in the UK will have clean air zones implemented in 2020 – they are Birmingham, Leeds, Nottingham, Derby and Southampton – due to current levels of pollution that exceed EU legal requirements on air quality. The detailed plan for these Cities is not complete but may involve a cost for vehicles that do not meet certain emission criteria when they enter a particular zone in the city.
There is also potential for sustainable electricity generation such as solar, wind & hydro which will help to cut the UK’s dependence on fossil fuels, and when electricity is generated from a green source it helps to decarbonise the UK.
Legislation is driving the change
There are two key elements of legislation that are driving low emission vehicles ( Excuse the pun! )
The first is the European C02 emissions limits – currently all car manufacturers selling products in the EU must have sales weighted Co2 average of 130g per kilometre or less – falling to 95g per km by 2020. This will be difficult to achieve without plug-in technology.
The situation is similar for commercial vehicles, currently 175g/km from 2017 reducing to 147 g/km from 2020.
The second piece of legislation is the Euro Emissions Standards. Euro Emissions Standard 1 was introduced in 1993 for cars – and we are now on Euro standard 6 ( this explains why you see EU6 in new vehicle descriptions.)
So what are your choices?
There are 4 categories of vehicles to look at.
Plug in Hybrid Electric Vehicle (P-HEV)
Extended- Range Electric Vehicle (E-REV)
Best suited for drivers with a mixed cycle of driving, and some stop start driving to maximise brake regeneration. Driving range is not limited as the hybrid car offers both petrol and diesel engines as well as the EV mode. The pure EV mode is very limiting, usually only a mile or so and at low speeds. Hybrids are often seen as a ‘half way house’ between petrol/diesel and PHEV/E-REV. They have a small battery/motor which recovers wasted energy when braking. It provides additional power on acceleration which allows a smaller more efficient engine to be used & provides 1-2 miles pure electric mode at low speeds. You cannot plug this vehicle in, so its electric range is very limited, but the driver does not have to do anything different to a normal petrol or diesel car so no compromise is needed to change to a hybrid.
Full hybrids are aimed at mainstream conscious drivers and perform similar to a standard petrol or diesel car – but with better fuel economy, using petrol/diesel mode for motorways and petrol/electric for town driving.
Plug In Hybrid P-HEV
A Highly efficient petrol or diesel engine with an electric motor and batteries. This enables a range of hundreds of miles using the internal combustion engine, with the ability to run on electric only at lower speeds or local journeys – or a combination of both. Plug- In Hybrids efficiently combine an electric motor with a petrol or diesel engine, and because electricity is cheap compared to petrol or diesel they can cost considerably less to run.
Extended range Electric Vehicle ( E-REV)
Extended range electric vehicles are electric vehicles with a plug in battery pack and an electric motor, as well as a small internal combustion engine. Like pure electric vehicles they only ever run on electricity. The small petrol engine acts as a generator to top up the battery charge and hence extending the car’s overall range.
Typically these vehicles have a pure electric battery range of around 40-100 miles before the vehicle switches on the range extender to charge the battery and increase the range. This typically results in tailpipe emissions of around 20-30 g/km C02
Pure electric vehicles have high performance batteries which provide power to an electric motor, which in turn drives the wheels. These vehicles need to be charged.
Electric vehicles must always have charge otherwise when the battery is exhausted the vehicle will not run. Because of this there is the potential for “range anxiety”. Range is currently typically 65-150 miles per charge, but there are other factors which must also be taken into account like outside temperature, and features being used in the car which are drawing from the battery power. ( Air conditioning for example.) Battery technology is steadily improving and some EV’s can cover 200 miles on a single charge, and with new vehicles coming to market and improving the range all the time it makes them suitable for urban, and extra urban mixed driving. Their zero tailpipe emissions will have great effect on reducing poor urban air quality.
As with any new technology prices are coming down, and plug in cars and vans benefit from Government grants. Running costs are significantly lower too, which could save you thousands during the life of the vehicle.
And if you are worried about charging – the majority of drivers simply charge their electric cars at home overnight, just like plugging in their mobile phone. This usually takes place on their drive or in their garage, or using a nearby on-street residential charge point. There are also over 13,000 public charging point connectors across the UK , including rapid chargers at 96% of motorway services, which can charge the average electric car to 80% in as little as 30 minutes.
As at April 2018 already more than 130,000 drivers are enjoying the benefits of electric and hybrid motoring. We have seen the majority of this growth within the last 2 years making it the fastest growing vehicle sector in the UK, and with over 30 electric vehicles to choose from many of the top manufacturers are now offering a plug-in vehicle as part of their range.
