6 things to consider when buying a charging station

1. Where would you like to charge your electric car?

Would you like to mainly charge your electric car at home at a charging station? Or are you out and about a lot and want to use a mobile charging station?

  • At home – you’re best using a permanently installed charging station
  • Out and about – a mobile charging station is suitable for this situation

A wallbox is a powerful socket for your electric car. Once it has been installed, you can use it to charge your electric car both quickly and conveniently.

With a mobile charging station, you don’t have to spend a long time on installations: a mobile charging station can be used immediately at any industrial or high-voltage socket. Unlike when buying a wallbox, you don’t need to spare a thought for how many kilowatt hours you’re allowed to charge for – the charging power is detected automatically.

Why is it better to charge a car at a charging station instead of at a domestic socket?

  1. our car charges safely at a wallbox. The power cables and fuses are protected.
  2. Your electric car is ready for use again much faster. For example, you can recharge a Fiat 500 Electric car in 1.5 hours as opposed to 8.
  3. Charging is cheaper. In addition to the actual electricity that flows directly into your electric car’s battery, you also need electricity to operate the charging elements (on-board chargers). The longer the charging elements are in operation, the more energy you consume. 

According to a study conducted by the General German Automobile Club (ADAC) (in September ), the vehicle electronics’ self-consumption is lower with a wallbox compared to a Schuko® socket since the battery is charged much faster using a wallbox. The operating time is shorter, meaning there are far fewer charging losses. 

Apart from that, the wallbox also resumes charging independently after unexpected errors or even a total power failure. That way, you won’t be surprised by a low battery level when you start your next trip.

2. How quickly should your electric car be fully charged again?

How quickly your electric car is charged depends not only on the battery capacity, but also on the charging power. This is determined by three factors:

  • the house connection’s power that is still available
  • the charging station’s maximum possible charging power
  • the car’s maximum possible AC charging power

The weakest link specifies the charging power that can ultimately be used. If you have decided that you’d like to use a wallbox, we recommend that you also consult an installation engineer. That way, you can rest assured that your house connection can provide this service.

You can flexibly manage how long you charge your electric car for. Anything between half an hour and 12 hours is possible, depending on several influencing factors. For instance, the charging time is influenced by the outside temperature and the battery’s aging process. A state of charge of between 20 and 80% is generally best for the battery. 

However, you can also set the charging power based on your charging behavior:

  • If you mainly charge your car at night, an 11 kW wallbox should be sufficient.
  • If you charge your car during the daytime, it should probably be charged quickly. We recommend using 22 kW if your car’s charging power allows you to do so. 

You can find out about the advantages of each charging power in the article published in our Knowledge Center: Checking the facts – 11 or 22 kW charging power?

3. How far is your electric car from the charging station?

A key question we often ask our customers, and that is often underestimated too, is the necessary charging cable length.

  • 4 meters might sound like a lot, but it’s actually a very short charging cable in that situation. 4 meters is only adequate if your electric car is parked with the charging port right next to the charging station.
  • We recommend using a longer charging cable for all eventualities.
  • We have found that most of you prefer a length of 6 meters. That way, you’ll be playing it safe, and can easily pull the charging cable to the next parking space.

4. What functions do you need in a charging station?

Charging stations now offer a range of additional functions that make charging your electric car even more convenient. Decide for yourself what else you’d like to do with your wallbox at home – apart from charging the battery.

Additional functions

  • Charging station app

    If you’d like to continuously keep track of how much electricity you’ve used for charging purposes and control your charging processes, the best way of doing so is with a charging station that comes with an app, such as by the manufacturers NRGkick or wallbox.

  • Locking the charging station

    If you charge your electric car in an apartment building, you might want to be able to lock your charging station. This works very well with an RFID function or using an app.

  • Billing

    Do you have a company car, and would you like to bill the charged electricity through your employer? In that case, we recommend using a charging station with a calibrated electricity meter, an app and an RFID function, from the likes of ABL. 

  • PV-Management

    If you’d like to charge your electric car with 100% solar power straight from your own roof, we recommend solar packages like the ‘Sun Tank Set’ with NRGkick or the SMARTFOX PRO Solar Energy Management System wallbox.

5. Would you like your wallbox to be connected to the network?

Once you know what you want your charging station to do, you can choose how it communicates best. Choose from WLAN, LAN, Bluetooth and mobile data.

  • Generally speaking, LAN offers the more robust connection. But a more stable WLAN connection  is an option too.
  • WLAN is often prone to interference and outages, so it is not always possible to ensure that all the charging stations are included in the network. 
  • Often, a modern wallbox offers a variety of interfaces. The charging stations are therefore always accessible. 
  • For data transfer over a mobile data connection, you need a SIM card. Please note that charging station operators don’t usually provide a SIM card. You usually get the SIM card from your backend operator.
  • What communication protocol the charging station uses to communicate is also important. This is relevant in company parking lots or at large properties. We recommend OCPP. It allows the charging station to connect to any backend to give you real-time insights into charging operations.

6. A charging station with a socket or with a fixed charging cable?

  • A fixed charging cable on the wallbox is the most convenient solution. All you have to do is unplug it from the wallbox, plug it into your car and start charging
  • The socket variant requires space at the front of the car. This is something you should take into account if space in your garage is tight. You will also find charging stations with an integrated socket in our store.
  • One advantage of the wallbox with socket is protection against damage. That’s why the cable-free wallbox is mainly used in public areas. People who use their own cable for charging purposes will usually pack it neatly in the trunk. 
  • If a cable is permanently installed, it can be left lying around, then end up getting dirty or run over by the next vehicle.

Good to know: What are the costs and waiting times like?

You can get a reliable charging station as a basic model from about €600. The price may increase depending on the equipment and additional functions. Additionally, do take into account the costs of professional installation by an electrical installation company.

The conditions at the planned charging site in particular play a role in this regard:

  • How far is the parking space from the fuse box?
  • Are wall penetrations required, or does excavation work need to be carried out? etc.

The waiting times for a wallbox vary at present depending on the model. Due to high demand, you may have to wait a little longer to receive your desired charging station. The waiting times in question can be found on each product page.

6 Decisions to Make Before Buying Commercial EV Charging Stations

Reading Time: 5 minutes

Electric vehicle (EV) charging is only continuing to grow in demand, with the number of public EV charging stations in the U.S. reaching over 61,000 in February (Pew Research). BloombergNEF predicts that EVs will reach 45% of global passenger-vehicle sales by , and with an existing discrepancy between EVs and public chargers, increased demand for electric vehicle charging ports is already here. So, with technology and industry developing at such a quick rate, how do you future-proof your investment into commercial EV charging stations? Let’s dive into six things to consider before you buy.

1. Level 1, Level 2, or DC chargers

There are three types of EV charging stations: Level 1, Level 2, and DC fast charging.

Level 1 chargers are typical for homes because they can be plugged into a common 120-volt AC outlet and have the longest charge times; charging a battery from empty to 80% can take 40-50+ hours for a battery electric vehicle (BEV), and 5-6 hours for a plug-in hybrid electric vehicle (PHEV)*.

Level 2 chargers deliver electric power to the EV, which then uses an onboard converter to convert the electricity from AC to DC. These are convenient for homes, as well as public locations such as shopping, dining, and office buildings. Charging a battery from empty to 80% can take 4-10 hours for a BEV and 1-2 hours for a PHEV*.

DC fast chargers complete the power conversion before it ever gets to the car. This enables much faster charge speeds, making DC chargers great options for vehicles that need to repower quickly — say, when on a road trip or operating a fleet vehicle. Charging a battery from empty to 80% can take as little as 20 minutes*, but not all vehicles are compatible, which brings us to our next factor to consider.

2. Compatibility

Compatibility varies between car models and charging stations, so it’s important to consider what type of EVs you expect to see most at your business.

Level 1 and 2 chargers work with all EVs in North America, though Tesla vehicles require an adapter. The SAE J and the North American Charging Standard (NACS), a combined AC/DC-compatible plug designed by Tesla, are the two connectors used at these AC stations.

DC charging has three plug options: SAE combo (CCS), CHAdeMO, and NACS. While capable of charging at rapid speeds, one downside of DC fast charging stations is that they are not compatible with PHEVs. For a thorough look at charger types and compatibility, visit ChargeHub’s guide.

3. Costs

Essentially, the cost will increase with the level of charger — but that doesn’t mean that the most expensive option is always the best for your business. Remember that not all vehicle models are compatible with all chargers.

There are multiple factors to consider in the cost: the hardware itself, infrastructure, maintenance, and electricity costs.

Hardware

Broadsign gives the following breakdown for hardware costs:

  • Level 1 chargers are the slowest and the cheapest option, ranging from $300 to $1,500
  • Level 2 chargers are more powerful and, with variations on model and brand, can range anywhere from $400 to $6,500
  • DC charging stations have the fastest charging speeds, costing from $10,000 to $40,000 for the hardware

Infrastructure

Chargers need the right infrastructure to carry the proper voltage and power output, which your property may not be equipped with. Potential infrastructure costs include a feeder and cable pole, power protection system, wiring, installation labor, and more. According to Broadsign, this can range from up to $1,500 for Level 2 chargers and up to $40,000 for DC chargers.

Maintenance

As with most things in life, EV chargers need occasional maintenance to keep them running in top condition. Depending on who you choose as a provider (more on that later), this cost could be baked in with the convenience of a partner service.

Electricity

This writes itself, but electric vehicle chargers need electricity to run, which has its own costs. According to OBE Power, this typically ranges from $0.09/kWh to $0.21/kWh.

4. EV incentives

Good news for businesses interested in EV charging: the U.S. government has begun incentivizing properties to help build EV infrastructure! According to the IRS, the Alternative Fuel Vehicle Refueling Property Credit is available to businesses and individuals that place qualified refueling property, such as EV charging stations, into service during the tax year. If all qualifications are met, businesses could be eligible for a credit of up to $100,000 for each qualified item of property.

5. Number of chargers

When planning for EV charging stations, give some thought to how many you should install at your business. A few factors to consider are how many of your employees/clientele are driving EVs, specific days or times your business sees increased activity, and which type(s) of charger you want to offer (charge times will factor into port availability).

Beyond the current number of EVs at your business now, it’s wise to future-proof your investment. According to CBRE, there was “an average of 12 drivers per active port in compared with an average of eight pre-pandemic (-).” If you’re installing infrastructure to support commercial EV charging stations, you may want to add more chargers as demand grows; ensure that any work you do now will accommodate future increased electrical capacity and enough space for additional chargers. This forward-thinking approach can be illustrated by three types of building codes for EV readiness: EV-Capable, EV-Ready, and EV-Installed. Putting this infrastructure in place at the beginning can reduce costs later when you’re ready to place additional business EV chargers.

6. EV service provider

There are many options for service providers to power your EV charging system, and this is an important decision that could provide a beneficial partnership over time. Choose a provider with a good reputation and experience, high uptime, and offerings that match the services you need. The base requirement for any provider is that it meets federal and state regulations. Beyond that, potential benefits could include full-service maintenance/repair, user apps, usage reporting, in-house software platforms, and more. Providers like ChargePoint have extensive capabilities and services to make your business EV charger experience seamless from setup to scaling.
