Edinburgh turns to ABB for future-proof electric vehicle car charging

Industry leader ABB’s Terra 53 CJG rapid multi standard chargers have been selected for strategic sites on Scottish capital’s road network

ABB electric vehicle charging technology has been installed for the City of Edinburgh Council at two strategic points on Scotland’s road network. Two ABB Terra 53 CJG multi standard rapid chargers rated at 50 kW and a 22 kW AC (alternating current) charge point supplied by ICU have been installed at South Queensferry and Ingliston as an extension of the nationwide ChargePlace Scotland network of electric vehicle charge points.

The City of Edinburgh Council selected ABB and ICU technologies for their proven reliability and value. The Terra 53 CJG rapid chargers will also play a role in future-proofing the council’s infrastructure. Not only does the Terra family meet the latest technology and safety standards but it has been developed in partnership with leading automotive brands to take future requirements of electric vehicles and batteries into account.

Michael Kellett, of The City of Edinburgh Council’s Sustainable Development team said: "We are really pleased with the ABB multi-standard rapid chargers and the ICU alternating current charge point that are all now fully installed and operational. Initial feedback from EV owners is extremely positive about the quality of the chargers. The council was very impressed with the service provided by ABB and electrical installers BMM Energy Solutions. It was a pleasure to work with them, an extremely professional outfit and easily one of the best installers we have encountered."

The council was keen to ensure that its EV charging infrastructure will deliver maximum benefit for road users. In practice this means the ability to charge more cars safely and quickly over a long life with high reliability. ABB’s Terra fast chargers achieve this through continuous charging, certification with the CHAdeMO v1.0 and European electromagnetic compatibility standards, and connectivity to a cloud platform to support payment systems and online service support, as part of the ABB Ability™ portfolio of digital offerings.

The chargers add to ABB’s installed base of fast chargers. Having sold a total of 5,000 Terra units since 2010, ABB’s chargers have demonstrated high reliability with an average uptime of more than 99.5 percent.

Broadly speaking there are two ways to charge a car: either using the car’s onboard charger, or offboard using a larger, faster roadside charger. Both convert AC, the type of electricity that is distributed in the electricity grid, to DC (direct current), which is used in batteries and electronic equipment such as smartphones and computers. Car manufacturers are keen to minimize the size, weight and cost of car components and in the case of the converter, this results in limiting the power capacity of the onboard charger, leading to longer charging times.

ABB chargers deliver DC power and incorporate a converter. This removes the need for a converter in the vehicle, making the vehicle lighter and increasing its range. It also enables the converter to be much larger and more powerful, reducing charging times.

To compare, a typical AC charger delivers 7 kW power for a charging time of 4-5 hours, whereas DC charging infrastructure with 50 kW capacity can charge a vehicle’s battery in only 20 minutes.

The chargers installed for The City of Edinburgh feature charging sockets that comply with DC CHAdeMO, DC CCS and AC Mode3 type 2 to ensure compatibility with current and future EV models.

Martin Hale, in charge of ABB’s for electric vehicle charging infrastructure for UK and Ireland said: “With potential for faster charging and greater range, it’s no wonder that the automotive industry is turning to DC power to charge electric vehicles. Having worked in partnership with the major EV manufacturers, we have developed our roadside chargers to charge more cars safely with high reliability.”
