Electro Rent-Automative-EV-Power

Electric vehicle sales are increasing rapidly across Europe, driving investment in charging infrastructure. As Alain Mignot, Inventory & Service Manager at electronic T&M equipment rental, leasing & sales provider, Electro Rent tells us here, it’s vital that this transition is supported by rigorous testing of technologies at every stage of development to ensure that charging can be conducted as quickly & reliably as possible.

The electric vehicle revolution is accelerating at a rapid pace. All over mainland Europe, governments are introducing financial and legislative support to stimulate consumer demand as part of concerted national efforts to reduce tail-pipe emissions and improve air quality.

In the UK, for example, a plan to outlaw the sale of new petrol and diesel cars has been brought forward 5 years to 2030. Similar aggressive timelines are being considered in many other European countries, as environmental considerations take priority.

These intentions are having a positive impact on the sale of electric vehicles (EVs), whose numbers continue to rise. 1 in 10 new car purchases in Europe were electric or plug-in hybrid in 2020, according to research by zero-emission lobby group, Transport and Environment – and this figure will increase to 15% by the end of next year, it predicts.

Demand for charging infrastructure
Electric cars are here to stay, then – resulting in a ramping-up of charging infrastructure. There will need to be around 3 million public charging points in operation in Europe before the end of the decade, according to industry projections, with countries like Germany, France and the UK set to have the most expansive plug-in charging networks.

This is all good from an environmental perspective. Yet careful consideration needs to be given to all aspects of charging infrastructure if charging points are to supply electricity to vehicles with maximum efficiency – thereby shortening the charge times required.

To achieve this, assuring the quality of the delivered power will be paramount. As the number of charging points increases, the requirement to deal with non-linear loads will likewise rise – leading to a greater prevalence of factors such as harmonic distortions. This is a significant cause for concern, particularly for utility companies, who will be responsible for continually maintaining the highest levels of power quality supplied through their networks.

So, how do we go about ensuring power quality of EV charging points during a period  of such rapid expansion and change? The answer lies with rigorous testing of components and systems, to ensure full compliance with ISO automotive standards and IEC electrical standards. Effective testing regimes can be deployed to overcome interoperability issues, with, for instance, electromagnetic compatibility-compliant components, norm-compliant procedures and compatible technologies ensuring fault-free communication between the EV and electric vehicle supply equipment (EVSE). These techniques can deliver safe,  fast and ultra-reliable EV charging, providing motorists with the convenience that they require to continue their journeys with a minimum of fuss...
