Approved OZEV Installers for Domestic and Commercial Electrical Vehicle Charge Point Solutions
What the Office for Zero Emission Vehicles does
The Office for Zero Emission Vehicles (OZEV) is a team working across government to support the transition to zero emission vehicles (ZEVs). We are providing support for the take-up of plug in vehicles, as well as funding to support charge point infrastructure across the UK. This will contribute to economic growth and will help reduce greenhouse gas emissions and air pollution on our roads.
OZEV is part of the Department for Transport and the Department for Business, Energy & Industrial Strategy.
Why do you need an authorised OLEV installer?
- Through using an approved installer you can obtain a grant from the ‘The Office for Zero Emission Vehicles (OZEV)’ for charge points installations via either the ‘Electric Vehicle Home Charge Scheme (EVHS) or the ‘Workplace Charging Scheme (WCS)
- The grant is can only be obtained only through a registered and approved OZEV installer such as AllStar Electrical.
- For more details on OZEV and why you require an approved OZEV installer visit the OZEV website
How to work out how long it takes to charge an EV?
Firstly you need to know the size of the vehicle battery measured in kW’s (KiloWatts). There are many different sizes from vehicle to vehicle e.g. the newer Tesla Model 3 has a 75kW battery installed, the Mini Electric has a 32.6kWh battery. To keep things simple, we’ll demonstrate using a 70kWh battery.
Secondly, you need to know the rate at which your EV Charger charges, measured in kWh. Domestic chargers generally range from between 3kWh up to 22kWh, although most UK houses have a single phase supply which means the maximum charge rate will be 7kWh. We now know our vehicle needs 70kW to achieve a full charge and our charger is charging at the rate of 7kWh.
Now it’s just some simple maths. 7 (kWh) x 10 (hours) = 70kWh, it really is that simple!
Now you know it takes around 10 hours to charge a 70kWh battery, you know it will take over 10 hours to charge any battery higher than 70kWh and less than 10hours to charge any battery lower than 70kWh.
However, 54kWh is the figure we’ve concluded as a rough average across 40 of the best selling EV’s.
Take the battery power and divide by the amount of power we can charge it with every hour
= 54kWh / 7kWh =7.71hrs
As this a decimal point and an hour is 60 minutes we need to convert 0.71hrs into minutes 0.71*60= 42.6 minutes
So the average time to charge an EV is around 7 hours 42 minutes!
By comparison it would only take around 64 minutes to achieve 100% charge using a 50kWh public charger. However, you need to bear in mind the amount of charge you require for the journey ahead. For example, if you know you only require 10% battery to get home, you may opt to only charge up to 25% capacity using a public charger and this would take roughly a quarter of the time, 16 minutes.
Home chargers require an AC single phase supply which most UK homes have and charge at a rate of 7kWh. Public chargers (known as rapid chargers) are usually DC and charge at much faster rates between 50kWh – 150kWh, though usually for a higher cost. Public rapid chargers found at charging stations, are also tens of thousands of pounds in comparison to commercial fast chargers or home chargers which are. fraction of the price.
