Charging Electric Cars At Home
Charging Electric Cars At Home & All Things EV
In December 2020, the government announced a ban on the sales of petrol and diesel vehicles from 2030, in favour of electric vehicles which don’t emit carbon into the atmosphere. This is a welcome move for planet earth and mankind as a whole.
Understandably there will be questions and plenty of them. Therefore, we have decided to research and provide better answers to as many of your top 50 questions as we could, in our ultimate guide to charging electric cars at home and everywhere in between.
Our research consisted of firstly creating a number of averages, based on forty of the best selling EV’s on the market in 2020/2021. Lots of the information available online, tends to focus on one particular vehicle battery size, notably 60kWh, which although is a common battery size, it doesn’t necessarily match the average battery size across a wide array of vehicles. We’ve concluded the current average to be closer to 54kWh. This is especially true when you factor in vehicles such as the popular Tesla Model 3 which sits at the higher end of the battery scale, boasting a 75kWh battery option or alternatively, the Smart EQ Fortwo city car which has a smaller 17.5kWh battery.
The size of your vehicles battery is key to answering questions based on vehicle range and how long your vehicle takes to charge. Vehicle weight also plays a part. As a general rule, the larger the battery size in kWh, the further the vehicle will travel on a single charge. However, larger batteries will usually take longer to become fully charged and are often heavier. Think of this like filling a 5 litre bucket of water, against filling a water 1 litre bottle of water. It will obviously take longer to fill the 5l bucket but you have 5 time the amount of water available. However, it will also be heavier.
Starting with the basics of EV…
What is an EV?
An EV is an abbreviation for Electric Vehicle. EV was a term adopted by the automotive industries to describe a car that runs on lithium ion batteries.
Electric cars are fuelled by electricity which is stored in the cars internal rechargeable battery. The battery powers an electric motor which then turns the wheels when the pedal is engaged. Batteries have a storage capacity measured in kWh. Batteries use on average 0.25kWh per mile and need recharging regularly.
The benefits of electric cars are endless. As well as a cleaner and safer environment, better air quality and an overall move towards a greener future, they are also cheaper to run, less hassle to maintain, quieter and are driving companies to begin inventing, innovating and designing, thus, creating a whole new economic sector.
What about charging electric vehicles? …
Where can I charge my EV?
The easiest and most efficient place to charge your vehicle is at home using your own charging station, such as the zappi eco charger. However, if you are running low whilst out on the road, there are over 12,000 public charge points available throughout the UK & Ireland, with more being listed daily. Charging infrastructure is growing rapidly, especially since the announcement to ban the sale of fossil fuel cars from 2030.
Charging your electric vehicle at home is the easiest and most cost effective way to charge. Most EV owners will top up their charge their vehicles over night ready for the morning. Charging a vehicle every night will cost around €1.20 to maintain full charge and €9.10 to fully charge from empty.
It is not a necessity to charge your electric vehicle every night, though one of the many beauties of owning a domestic charge point, is your ability to do just that, which in turn saves you time, money and with less reliance on public chargers.
Not all electric vehicle chargers are the same, though most modern EV’s come with Type 2 sockets, which are compatible across all the variations of charger. For example, home chargers tend to be AC and charge at the rate of 7kWh. Public chargers are usually DC and charge at faster rates. There are also 22kWh chargers available, though not all vehicles can charge at these higher rates.
How long does it take to charge an electric car battery?
The time it takes to charge an electric car battery is dependent on the speed of the charger. Typically a public charger would take around 60 minutes to achieve a full charge, whereas a typical 7kWh home charger would take around 7hrs 42 minutes.
Many companies across Ireland are offering free electric charging points as an incentive for customers to use their services, in the same way companies offer free parking. Like parking, there will likely to be time limits involved and a requirement to purchase or use the services.
Rapid chargers draw Direct Current (DC) at rates which are considerably faster than an average domestic charger which draws Accelerating Current (AC). AC is converted to DC before it hits the vehicle which slows down the overall process, whereas DC bypasses the conversion process, hence faster charging speeds.
A granny charger (Type 1) is ultimately your cars spare charger, which allows you to charge your EV with any standard 3 Pin Socket, though as the name suggests, It charges at a far slower speed of 1.2kWh (10amps) compared to the usual 7kWh via an average home charging point.
How much does it cost to charge an electric vehicle at home?
The cost of charging an electric vehicle in the United Kingdom is dependent on numerous factors including the specification of the vehicle, size of the battery and how the car is driven. The cost also differs between domestic charging and public charging.
The price per kWh of electricity differs throughout the Ireland, however the average price per kWh sits at around 16.80p. The average sized battery across forty of the best selling EV’s is 54kWh: the average cost of a full charge at home is €9.10 which equates to an average of around 211 miles of range.
The effectivity of charging your vehicle every night or once a week is fairly relative in terms of end result. On average we use 7kWh of battery per day. Therefore, it’s the difference between charging at home for 30 minutes to 1 hour per day or 7-10 hours in one charge, dependent on battery size.
How do people with no driveway charge their electric cars?
There is lots of dialogue currently between government and the EV industry, surrounding electric vehicle owners without driveways. If you have a carpark or allotted parking bay, it is possible to have a charger located. If you rent the building or land, your tenant may have to think about EV infrastructure and regulations going forward. We recommend both renters and tenants keep an eye on the .gov website for updates to EV regulations. Other current options are to use public chargers, work place chargers or sharing schemes. It may also be worth contacting your local authority regarding infrastructure plans within your area. Schemes such as the ORSC are available in some areas.
The best way to have an electric charging point installed, is to call a certified OLEV approved installer who will ensure your charger is installed to the highest recognised safety standards. In doing so, you can then claim the OLEV grant towards both the charger and the installation.
More about vehicle range & the frequency of charging …
How far can an electric car go?
The average distance an EV can travel is 211 miles. However, this is dependent on numerous factors including the size of the battery in kWh, the vehicles weight & design and ever fluctuating factors such as the weather.
What happens when an electric car runs out of battery?
If you have never run out of petrol when driving, it is unlikely you will run out of battery. The concept of recharging is the same as refilling your vehicle. We’d recommend heading to the nearest charging station when your vehicle reaches between 15-20% capacity. A recharge on a public DC charger will take between 10-30 minutes dependent on your vehicles charging rates.
How many kWh does an EV use?
In the perfect conditions, an electric vehicle (EV) will use on average around 0.25 kWh per mile, though this figure will fluctuate slightly based on changes in rolling resistance, temperature, wind direction and daily weather conditions.
How low can my electric vehicle battery go before it needs charging?
To maintain the longevity of a vehicle battery it is recommended that you maintain a minimum charge of at least 15-20%. The average distance between charge points in the UK is 6.1 miles meaning the bare minimum charge required would be 4%, though this is not recommended.
What is the longest range on an electric car?
620 Miles is the official range of the Tesla Roadster and currently in the top spot for the longest range on an electric car. The average between the top 10 longest range vehicles is 342 miles.
What is the range of an EV?
211 miles is the average range of an EV, when comparing 40 of the best selling electric vehicles in 2020. Range is determined by many factors including vehicle weight and the kWh size of the battery.
How much does it cost to charge an EV at home?
It would cost £7.77 on average to fully charge an electric vehicle at home and most users would fully charge once per week. This is an average of £31.08 per month.
Why are electric vehicles better for the environment? …
Are EV’s better for the environment?
EV’s are much better for the environment. The movement towards electric vehicles will play a giant part in the worlds quest towards carbon neutral. Electric vehicles produce zero carbon emissions, whereas the average combustion engine releases between 8,000 – 10,000 grams of CO2 per gallon.
How green is an electric car?
Electric cars use Lithium-Ion batteries with zero carbon emissions. Therefore, electric cars are certainly greener than cars which burn fossil fuels and release carbon into the atmosphere. Arguments made against the transition to electric vehicles, often have vested business interests in fossil fuels or heavy pollutant industries.
Do electric cars give off emissions?
Electric cars don’t give off emissions directly. The positive changes in air quality during COVID 19 lockdown periods is living proof of just how much carbon is released into the atmosphere on a daily basis through fossil fuel vehicles. Indirect emissions may be produced during the manufacturing processes and through the generation of electricity, though switching to electric vehicles will drastically lower overall carbon emissions and improve air quality.
Will power stations and the grid be able to cope in our EV future?
The introduction of time of use tariffs in particular, will encourage EV drivers to charge their vehicles during off peak periods when demand on the grid is lower. EV drivers can expect prices often as low as 0.03 – 0.05p per kWh during less demanding periods. Equally, expect higher rates during busier periods.
More about vehicle batteries …
How long should an electric car’s battery last?
15 years. An electric car battery will last anywhere between 8 – 22 years, dependent on numerous factors including weather conditions, charging habits and how the car is driven. Most manufacturers offer a 5 – 8 year warranty on their batteries.
A common question amongst EV newbies and early adopters alike. Conditioning an EV battery by maintaining a charge between 20% – 80% is becoming a popular practice amongst electric vehicle owners. This helps to prolong the batteries health and longevity by keeping the ions in a steady state of charge and elongating load cycles.
How long can an electric car sit without charging?
If you are leaving your electric car for a lengthy period of time without driving it, the car battery will discharge anywhere between 1-4% (0.50 to 3 kWh) a day dependent on the cars mode and particular power sapping features. Some of these features could be turned off to prevent higher rates of discharge though, we’d recommend referring to the owners manual for your particular vehicle. Equally, some vehicles go into sleep mode.
The ions in a battery don’t like to remain in a state of being under charged or equally overcharged. Therefore, keep a steady medium and decrease the charging range to between 20% – 80%, leaving 20% headroom either side, opposed to charging from 0% to 100% (Full Cycle). 20% becomes the new (0%) and 80% becomes the new (100%)
Can you over charge an electric vehicle?
It is not possible to overcharge a vehicle battery. The charge process will cut off when the battery is at full capacity. If there are uncommon cases where batteries have overcharged, it is possibly due to either a fault with the battery and/or failed vehicle components relating to charge regulation.
Regenerative braking, more commonly known as ‘regen’ in the electric vehicle industry, is the transfer of kinetic energy to chemical energy which is stored in the vehicle battery. This energy can then be used to drive the vehicle.
Almost all batteries can be recycled, particularly lithium ion batteries which are found in electric vehicles, mobile phones and many other rechargeable devices.
Maintaining an EV…
Are electric cars more reliable?
Electric cars are considered more reliable. Electric cars tend to score more highly in the reliability categories across numerous customer surveys, which is not surprising, as there is less that can go wrong in a battery powered vehicle. The most common fault in electric vehicles is with the battery itself, which is very easy to replace and usually under warranty with the vehicle manufacturer.
Do electric cars break down less?
Electric cars brake down less often than those with internal combustion engines, due to the fewer mechanic moving parts involved, as well as being less prone to oil leakage and blockages. Battery power is a simpler process and far cleaner.
Do electric cars need oil?
Fully electric cars do not need motor oil. Motor oil is used to lubricate the moving parts of an internal combustion engine for which electric vehicles don’t have. Instead, electric vehicles are powered by a rechargeable lithium ion battery.
Do electric cars need servicing?
Electric cars need servicing annually just like any other passenger vehicle. Brakes, windscreen wipers, seat belts and vehicle safety features still need servicing. However, savings can be made on oil changes, filters and combustion engine faults, which are no longer required.
Do electric cars need an MOT?
Electric cars still need an MOT annually after 3 years from new. There is a slight variation in the testing stage In that EV’s don’t require an emissions test.
Are electric cars manual or automatic?
Electric cars are automatic in terms of the similarities in driver experience when compared with a manual vehicle i.e. no clutch or gearstick. However, when comparing an automatic combustion vehicle and an EV, the technologies are entirely different. Drivers will likely notice the difference in acceleration speeds when driving an EV and the quietness of the motor.
Do electric cars need a gearbox?
Electric cars don’t need a gearbox, clutch or gear stick because they don’t have mechanical gears. Electric vehicles only have one gear. The average RPM range of an electric motor is 20,000 rotations per minute opposed to an average of 7000 in a fuel combustion engine.
Financial Incentives & Grants …
Do you have to pay road tax on an EV?
As a vehicle owner and road user, you must still register this vehicle either on of off the road. However, road tax is charged based on carbon emissions and as electric vehicles emit zero carbon, EV’s cost £0.00 in road tax.
What is the electric car grant?
There are numerous grants available through the government for people and companies opting to switch to electric vehicles. The average driver in Ireland can save €5000 on a new EV and €600 on a home charging point.
Do I have to pay congestion charges?
Currently, both electric and hybrid vehicles are exempt from paying inner city congestion charges. However, from October 2021, only fully electric vehicles with zero emissions will be exempt from these charges.
