Electric vehicle charging
Posted on 30th April 2019
The government says it plans to introduce low and zero-emission transport.
Today you could go a long way and without seeing an electric vehicle, but numbers are slowly increasing. Only 1.8% of new cars registered were electric or low-emission in 2017, but that figure rose to 2.5 percent in 2018.
These new breeds of vehicle are better for the environment and will also help to improve air quality and the health of people living is busy towns and cities. As more Ultra Low Emission Zones (ULEZs) are introduced, the demand for both private and commercial electric vehicles will increase – so where will the chargers be?
For example, Birmingham Airport plans to introduce a fleet of fully electric buses later this year that will charge at the terminal’s bus stops.
Installing electric vehicle (EV) charging points
While daily school runs and the weekly shopping trips might allow plenty of time for recharging, local taxi and delivery businesses will want a faster turn-around.
At home a domestic supply could provide a steady charge at 3 to 22 kW of AC power over 4 to16 hours, with no need to upgrade.
On the other hand, offices, commercial properties, multi-family housing, hotels and car parks will probably need DC chargers delivering 20 to 25 kW for 1 to 3 hours.
For people who are looking for 20- to 90-minute charge times 50 kW will be the minimum requirement. This could include installations for supermarkets, out-of-town retailers, restaurants and motorway service areas.
For super-fast charges of just 10 to 20 minutes in city and suburban areas, DC high power points delivering 150 to 350 kW or more will be needed. These might also be used for electric buses and commercial vehicles.
It will be a major undertaking to install a viable network of charging points. It will be important to make sure that it will be fit for purpose for several generations of electric vehicle technology.
Chargers will need to be compatible with the latest generation of the EV charging standards and have scope to upgrade as standards evolve.
The technology should be safe, secure, reliable and straightforward to install and maintain.
