EV Charging is Like Hot Water

Energy is intangible and 'ampere' isn’t a word of daily usage. It’s hard to understand how much power is consumed on average during the day. Even if you know that your fridge is using 30-kilowatt hours per month is it not trivial how much power you have left for other devices.

Think about 10 amperes or amps. Let me guess what you pictured. Nothing. Because who really can understand power like this.

Now think about one gallon of HOT water. Easy, right?

There is usually a water tank either in your single family home or a multifamily building, which heats up the water. Once the hot water is used you might need to wait before taking a warm shower or suffer the cold. Sounds awful? It is, but I'll explain why this rarely happens.

How It All Works

The similarity between hot water and energy is that you cannot consume more than is available. The bigger the tank the more water available; the “larger” the panel the more energy is available. The major difference is the allocation of the supply.

So, what does that mean?

Very likely you almost never run out of hot water because the architect allocated a certain amount of water per apartment and tenant’s water consumption behavior rarely changes drastically over time. The allocation system works perfectly and we take it for granted that we have a reliable water supply. For energy, we might run into issues in the future because consumption habits will change and allocation of energy doesn’t work the same way water does.

"Why will energy consumption habits change? Electric Cars."

The more electric cars hit the road, the higher the demand for electricity, especially at home. Lets think about water again in order to explain how car charging works. The panel is the tank and the car chargers are the fountains. Each tank carries 10 gallons, every fountain needs 5 gallons, which means we reach maximum capacity at 2 fountains.

But wait, what if those fountains are not in use at the same time?

That's exactly the point, its extremely rare that all the fountains turned on at the exact same time, and the same is true when we are talking about EV chargers.

Intelligence Matters

For traditional car chargers it doesn’t matter whether they are in use or not, they block off all the power as if they were. However, SmartPower changes all that.

SmartPower works on the same principal as water allocation. It allocates the energy wherever it is needed. In the fountain example, the installation of more than 10 fountains is possible because the system recognizes how many fountains are used and how much has been consumed, which means that far more fountains can be fed from the same tank. Cool, huh?

Let’s translate that example into electrical language. We have 100 amps available on a panel. Traditional chargers need 40 amps, which means the building is maxed out with 2 chargers. SmartPower makes it possible to install up to 15 chargers with 100 amps of available power because it used the available energy where and when its needed and doesn’t dedicate it in advance.

Don’t waste your money on big tanks or bigger panels. Go with intelligence. You and your wallet will be glad you did.
