What is Load Balancing? Do I need it?

Never Enough Power to Balance the Load

The electric revolution is in full swing, and site owners across the world want to install chargers. They want to provide better services to their customers, to make their parking lots generate revenue, or to attract EV-owning tenants and clients. This all sounds great, but business owners are running into a real problem when it comes to balancing the load of all that demand for charging!

The world we live in right now wasn’t constructed in the electrified age. Electrical grids or wiring can’t always keep up with the appetites of dozens of electric vehicles. They want their power, and they want it now!

Is the problem due to my power panel? Maybe. Perhaps it’s not able to support charging very many cars at once. Maybe the limitation is due to the power provided by the utility. Not every grid was built to distribute power in the EV era. Either way, what do you do when there’s a power constraint that says you can only install 4 charging stations but you have space for 16? That’s 4x more! Is there anything you can do to take full advantage of the space you have without the expense of completely redoing your electrical setup?

Option 1: Install 4 Charging Stations

Okay, it’s less than ideal, but you could just go with what you have. Some charging station operating systems, like Noodoe EV OS, can send a text message to a user when their vehicle is fully charged. This encourages the driver to move their vehicle so they aren’t charged an occupancy fee. Most people don’t want to pay extra money for using the charger space when their vehicle is already full. This potentially works for some places, like restaurants or shopping malls, but it’s a real problem for hotels, apartments, or business parks where the car’s owner might be sleeping or in the middle of a workday. It’s not a perfect solution, but it uses what you’ve got without worrying about power management.

Option 2: Noodoe EV’s Smart Energy Management

We could also call this fancy energy math. Let’s say you go ahead and install the 16 chargers you wanted to install, even though your available power is only enough for 4. Load balancing is the magic that makes it possible to install up to 4x as many chargers as you originally thought you could support.

How Does it Balance the Load?

As each car pulls up to a charger, everything works as expected. Cars 1-4 plug in, and the drivers go on their merry way while their vehicles charge up. When that fifth car pulls in, Noodoe EV OS takes over. 

The program watches the chargers to see how much energy they’re drawing and how much they need to keep the total energy use under the max usable load. This means that when the 5th or 10th or 16th car pulls up to charge, the other chargers automatically change to make space for the next vehicle. They automatically balance the load!

The Magic of Load Balancing

It’s like everyone scooting their chairs together to make space for one more person at the dinner table. The more the merrier! We may be squeezed in a little tightly, but we can definitely make room for one more.

When that new car shows up, the other chargers redivide the energy available across the chargers. When one vehicle finishes charging, the station recognizes that it’s done and rebalances or reallocates the power that the car was using. There’s no need to move one car so another can takes its place to charge. Instead of moving the cars, we move the electricity. Everyone else gets a little more power while that vehicle hangs out, taking up space but not limiting the power the other cars can use. The best part is that the whole thing happens automatically. 

Your Grid Can Do So Much More Than You Ever Imagined

The Bottom Line

There are different ways to approach the problem. However, it’s important to remember that there’s no reason to feel limited by your grid. Noodoe EV OS’s load balancing can support up to 4x more chargers than the standard setup. It’s worth a look if you have restrictions on power but not on space.
