Electric Car Charging - A Brief Overview
The biggest set of questions asked by Volt-Age customers and from those who have yet to experience driving an electric vehicle involve charging and range anxiety, which is only natural as we are all so familiar with the need to fuel our cars to keep them moving on the road. We have provided a brief overview to try and answer any concerns and should you have any more questions then please get in touch and we will be happy to help.
New to Electric Vehicles?
One of the main differences with electric vehicles and internal combustion engine vehicles is the way in which fuel is replenished. With a car with an engine, you need to fill it up with petrol or diesel. In much the same way, charging the battery in an electric vehicle is the equivalent of filling the tank in petrol or diesel car.
Unlike combustion engines, there’s currently no way to instantly add range to electric vehicles, as you would when topping up with petrol or diesel at dedicated stations but with the number of manufacturers now producing and developing electric cars, the quality and speed of vehicle charging is improving and will only get better as time goes on.
What is range anxiety?
‘Range Anxiety’ is the fear that an electric, or any vehicle is not going to have sufficient range to reach the final destination. The term has certainly become more common with the introduction of more and more electric vehicles on the road in the UK, but with the range cars are capable of covering on the increase, and the wider availability of electric vehicle charging points there is nothing much to worry about. Should you choose to hire an electric vehicle from Volt-Age, we will do our best to help you on your way and overcome any concerns about range.
A common fear for new users, we’ll guide you through the options when it comes to charging the vehicle. Whether you are an ‘overnight charger’ or if you find a ‘little-and-often’ methodology works best, either way, charging points can be found all over the country, even in local supermarkets, with more being added daily.
Charging an ELectric Vehicle At Home
The most convenient time to charge a vehicle is when there are long periods of inactivity. For some E.V users, this naturally occurs when they come home from work in the evening. If you are purchasing one it is certainly worth considering looking at a permanent electric car charger. Costs are around £350 after the OLEV government grant for a 7kW charge point, enabling 3x faster charging, taking the 12 hour charge time down to 4 hours.
All of our electric rental cars come with a domestic 3 pin plug charger, that will charge wherever there is access to a standard plug socket. This is the slowest method of charging, however it may still add enough range to the vehicle depending on your usage, with around 95 miles added for 12 hours of charge. Although using a standard socket is entirely possible, a more suitable way of charging at home, is to have a dedicated charge point installed - something you might just consider after spending some time with our electric fleet…
You may believe that charging at home is only suitable when off road parking is available, but change is on the way, with steps are being taken to help those who do not have off road parking. Portsmouth City Council have installed a number of Ubitricity chargers, that utilise existing street lights and with other innovations such as the kerbside chargers from Connected Kerb, charging at home is becoming more accessible everyday. There is also a petition to change the law, calling for terraced house owners to be able to install chargers, with a concealed cable across the pavement to their car.
Charging an E.V in Public
Using public charging stations can be a minefield and very daunting for new E.V users. There are many companies operating the points, all with different methods of handling the charging transaction. We advise researching the charging stations along your journey or in your local area so you can prepare, and avoid a potentially stressful situation. You will however find that in most major cities there is a wide number of public charging points in council car parks and shopping centres, with the situation only improving all the time with more of us taking up the practice of driving greener vehicles.
Find a Electric car charging station with our map
Use our Map, which comes courtesy of Open Charge Map.
A E.V map tool such as ZapMap becomes extremely useful for researching charging points. ZapMap is a free to use App and website that displays all the charge stations over the U.K, the current status of the station (showing ones that are not in operation/faulty), the operator and their tariff. Another feature is the ability to filter the power output of the station. Most home chargers output at either 3.6kW (slow) or 7kW (fast) but for businesses that have a 3 phase supply there are also AC charge stations that output 22kW (fast).
Some Supermarket’s have started to install charging stations in their car parks, and whilst they are generally free to use, they are also slow (3.6kW). This is where a little and often approach can help ease range anxiety. Imagine if there was a petrol pump next to your parking space that gave out you a couple of litres of fuel for free! Some retailers such as IKEA have implemented DC charging stations that are capable of rapid charging vehicles with 50kW of charge. This vastly reduces the amount of time it takes to fully charge a vehicle, with a typical charge only taking 45 mins.
As battery sizes increase, so does the time to charge them. Advances in charging technology are keeping these charge times steady, with 100kW DC chargers starting to roll out throughout the U.K. Charging at AC stations usually involves using your own type 2 charging lead, which we provide with all of our vehicles. DC charging stations have a lead tethered to it, and are a different shape to the cars AC port. The most common charge ports can be seen below.
CCS and CHAdeMO are found on cars such as the BMW i3 and Nissan Leaf and are for DC Rapid Charging. Type 1 chargers are no longer offered on new vehicles in Europe, but can be found on the Vauxhall Ampera and first generation Nissan Leaf. Type 2 is now the standard in Europe for AC charging, and combines with CCS. Tesla also use the Type 2 connector in Europe for their Superchargers.
Charging Station Operation
Most charging stations are now operated via a card or app, which handle the charging transaction. As with most online based services, you register for an account and add payment information into the operators app. This then allows them to bill you for the charge. An older alternative method is to sign up directly on the operators website, with them sending you a “charge card” in return. This work in exactly the same way as the mobile app but works well in bad signal areas. Instavolt have begun installing stations that work with contactless debit/credit cards, removing the need to register an account or have an app.

Having developed their own supercharging network, Tesla have the enviable position of being able to provide a charging service which is second to none. Each Tesla car is connected the internet, and has a payment account registered to it. This allows the car to talk to the Supercharger, authorising the charge with no input from the user. It is simply plug and pay. The car then displays the costs and all charging information on it’s main screen. Some Tesla models even came with free supercharging for life when first purchased. In Europe, Tesla’s are compatible with all the Superchargers regardless of the country they are situated in.
