Mind the Grid: How to fight grid overloads with smart EV solutions

Smart chargers are the key in rescuing EV energy grids

As electric vehicles continue to gain momentum among European drivers, an emphasis on energy supply control has also risen. Let’s take a look at the main cause of EV energy grid overloads, and what needs to be done to avoid them.

Supply and demand

While it can hardly be argued that electric vehicles are the future of sustainable driving, the increasing number of EV drivers are now facing a peculiar conundrum: the more EVs require simultaneous charging, the more potential damage their charging can lead to energy grids. In fact, according to a recent study by the UK think tank Green Alliance, these energy overloads could result in full blackouts to the UK’s national grids.

What’s this, you ask? How can such a sustainable way of driving be an energy hoarder? Well, there’s a simple reason for this. It’s called the abundance of “dumb” chargers.

"Investing in smart charging is paramount to solving the problem of grid overloads." James O'Neill, Ensto EV Solutions UK director 

Smart EV solutions shape the future

For the uninitiated, dumb chargers function with only a single purpose: they charge, and do little else. Applying many of these in a row means that every single charger will hog the maximum power available at peak hours. It’s little wonder, then, that grids might end up overloading.

A crucial remedy for this is investing in Smart chargers. To quote Dustin Benton, the author of the Green Alliance report: “Governments should say all chargers from now on must be smart.” Smart chargers will store energy acquired from off-peak times and automatically use it when required. This will significantly alleviate the strain on grid points, eliminating blackouts and providing efficient energy loads to any connected EVs.

Balance of the Load

At Ensto EV solutions, we’ve specialized in creating EV charging products that are not only high quality, but also smart. In fact, our Dynamic Load Management feature is designed specifically to remove the problem of grid overloads: it monitors and allocates the current feed across multiple charging points with a possibility to limit required capacity during peak pricing periods.
