Generally, the fast you charge, the more it will cost to purchase and install a charger. And since costs can increase quickly with higher power requirements, it’s important to your budget to choose a charging speed that matches the range-replenishment requirements you expect.
Here’s a table that will help you decide:
Household outlet or “Level 1” charger: 1.3k W (3 to 4 miles per hour)
Clothes dryer outlet or “Level 2” charger: 7.7 kW (20 to 25 miles per hour)
The answer to this question will driven mostly by your budget. Generally, it costs somewhere between $5,000 and $10,000 to install one EV charger on a typical commercial property. Of course, these costs can vary widely (less or more) depending on whether electric panel capacity is available, the power requirements of the chargers you choose (faster means higher cost), how far the chargers are located from the electric service panel or transformer, and how much pavement and other structures are between the electric service and chargers.
To get the most for your hard-earned money, leave as many parking spaces between your EV chargers as possible. This way, you can simply move the charging cord from one car to another without having to move cars. If you put chargers in every adjacent parking space, when one car is done charging… the charger cannot be used until the fully-charged car leaves…
The best place to put chargers is in “head to head” parking areas, where one charging cord can easily reach four or more cars! When one car finishes, another driver can simply swing the cord over to their spot and start charging.
In the market today, there is a dizzying array of EV-charging equipment available. Often, the difference in cost between two charging units with identical re-charging speed can be several thousand dollars.
Fancy network chargers are expensive because they’re equipped with things like color video screens, card readers, network electronics, cellular radios and whole host of other expensive components that are present in every single charger. Would you stand outside and watch a video screen while you waiting for your car to charge? Why pay for unnecessary expensive components and features you’ll never use?
Why not make a $500 charger do all the things you wantfrom the $5,000 chargers?
That’s exactly what the HYDRA-R provides; the HYDRA-R makes $500 chargers do all the things $5,000 chargers do…at far less cost. The hardware costs less, and so do the metering, reporting and billing services you choose.
Pricing is the most effective tool for managing usage.
Free means you’ll never be able to provide enough for everybody. In your ECON 101 class in college they told you that the demand for commodity at the price of zero is infinite…which is definitely true for vehicle fuel.
Facilities managers that start with free EV charging often wish they could go back in time and start with a small fee, somewhere close to what EV drivers pay at home, to ensure that charging is available for those who need it the most.
If it was the same price at work as it is at home, how often would you charge at work?
You get the picture….
Please read on…it’s a bit complex, but it’s really important for helping you make good decisions regarding EV-charging pricing.
If the driver of a 40-MPG gasoline car pays $3.50 for one gallon of gasoline, they can drive 40 miles. if the driver of 3-mile-per-kilowatt-hour EV buys electricity for $0.26/kWh, they can drive the same 40 miles for the same $3.50 — remember this number, $0.26 per kWh….
Now let’s say a typical driver travels 20 miles to get to your location. And let’s say you get two people every single workday to replenish their trip at your $0.26-per-kWh charger.
If you pay $8,000 (all in) at 5%, to install an EV charger, and $100 per year for maintenance, simple financial math shows that it would take about 16 years to recover your costs…if you’re able to convince EV drivers to pay the equivalent cost of $3.50 per gallon!
Sure you can do your own billing, IF your network and data services provide lets you have access to all of your data. Some network providers purposely make it difficult for you to do your own billing, because they’d rather sell you an add-on service.
Before you decide on network services, make sure you know how much of YOUR data you’ll be able to access.
