As you join the electric revolution, choosing the right EV charger becomes as critical as the vehicle itself. The appropriate charger enhances your driving experience and ensures the longevity and efficiency of your vehicle. We at Elecology offer our expertise to help you navigate through the myriad of charging options and make your switch to electric mobility seamless and well-informed. Let's take a look at five of the most crucial factors you'll want to consider when choosing an EV charger:

Charging Level

When it comes to selecting an EV charger, you'll first need to understand the different charging levels available. Domestic plug sockets are the most basic outlets you'll find in most homes. They're slower but offer plug-and-play convenience, which makes them a straightforward choice for many EV owners who require an EV home charging point installation. In contrast, there are 7 kWh and 22 kWh chargers that significantly cut down charging time, making them popular for both home and public use. Then there are the DC Fast Chargers, which provide the quickest charging but are more suited to commercial settings due to their higher installation costs and power requirements. For the most part, it's companies that are in need of a high-grade workplace EV charger installation that will be investing in the most powerful charging solutions.

Choosing the right charging level depends on your specific requirements and usage patterns. Evaluate factors like your daily commute, available charging time, and budget to determine what sort of charger will meet your needs best. If you have a longer daily drive or need to recharge your EV quickly during the day, for instance, a 22 kWh charger might be the ideal choice. On the other hand, domestic plug sockets are excellent for overnight charging at home. By understanding the distinctions between these charging levels, you can make an informed decision that aligns with your EV's charging requirements.

Charging Speed

The charging speed of your EV charger is a vital factor that has a direct impact on how convenient it will be to use your electric vehicle. This speed is determined by the charger's power output, measured in kilowatts (kW). A higher kW charger will fill up your EV's battery faster, but you'll need to match the charger's output with your vehicle's maximum charging capacity to avoid unnecessary costs.

Connector Type

The connector type of an EV charger is a pivotal factor in ensuring compatibility with your electric vehicle. Specifically, different EV models come with various types of DC charging ports, such as CHAdeMO, CCS (Combined Charging System). Choosing the right connector ensures that the charger can effectively communicate with and power up your vehicle, which makes this an essential consideration for any EV owner.

Installation Requirements

Proper installation is key to the effective and safe operation of an EV charger, as installation requirements can vary significantly based on the type of charger and the existing electrical infrastructure of the home or commercial property. This process often involves assessing your home's electrical capacity, potentially upgrading to a 7 kWh or 22 kWh charger, and ensuring compliance with safety standards.

The best way to ensure that your EV charger is safely and correctly installed is to work with a reputable electrical contracting company with specialties in EV charger installation. These organisations will walk you through the entire installation process, from the initial site survey to the installation itself, and many will even provide post-installation support to make sure that your chosen charger works as intended. By investing in comprehensive service, you secure not only a safe and efficient setup but also the peace of mind that comes from knowing your installation is in expert hands.

Cost and Incentives

The cost of purchasing and installing an EV charger can be a considerable investment. This cost includes not only the price of the charger itself but also any necessary electrical upgrades and installation fees. Fortunately, understanding and navigating the available financial incentives and rebates can significantly offset these expenses. These incentives are often provided by governments or local authorities to encourage the adoption of electric vehicles.

You can start discovering available incentives by visiting official government websites, which typically provide comprehensive information about national incentives and grants for electric vehicles. Contacting your local council, EV associations, and related advocacy groups in your area may also give you valuable information on more regional programs and incentives to promote EV adoption. Lastly, if it's personalised guidance you seek, you might consider working with a financial advisor or consultant who specialises in electric vehicle incentives and finance. These professionals can offer tailored advice based on your individual financial situation and requirements.

In embracing the future of electric mobility, the right choices today pave the way for a more sustainable tomorrow. At Elecology, we are committed to guiding you through these choices and making your journey to electric vehicle ownership as smooth and efficient as possible.

Top 5 questions to ask before buying an EV charging station

You may still sometimes hear that charging station is not really needed to charge your EV at home since you can use the simple plug. Well, even though it is technically possible, it is really not recommended and not efficient. Firstly, it is not safe, secondly EV charging station speeds up the charging up to 9 times and also offers various smart features. But before you buy a charging station these are the important questions to answer.

1. How fast will my EV charge to 100%?

To estimate the charging time you need to know:

  • Size of the battery
  • Power of the onboard charger
  • Power of the charging station

Charging time = battery capacity (kWh) / charging power (kW)

First of all it is important to know the power of the onboard charger of the EV because it determines how much power EV will be able to take. So, for example a car with 11kW onboard charger connected to 11kW charging station will take around 5 hours to charge. Interesting that if we have 22kW charging station charging time will remain 5 hours in this case as charging speed is limited to 11kW (power of the onboard charger).

Important to mention that charging to 80% is often enough (unless you are prepared for a longer trip) as after EV is charged up to 80% charging will be much slower for the remaining 20%.

2. How powerful of a charging station do I need?

We could twist the question and ask how fast do you want it to charge?

For example if you own 40kW Nissan Leaf with 7,4kW onboard charger, there is no need to buy 22kW station as charging time will not decrease starting from charging at 7,4 kW power. However, owning Tesla Model S and having 22kW station can decrease the time needed to charge to 4 hours (compared to 8 hours charging with 11kW or 11,5 hours with 7,4kW charging station).

Rule of thumb would be choosing 3-phase 11kW station for home as it is the most universal, however should look individually what makes the most sense.

3. What should I do if I have limited power supply? Do I need to increase it?

Not necessarily. While different devices in the building consume energy, adding EV charging infrastructure poses the question of whether we need to increase the power supply? In many cases it is not necessary because smart charging

feature called Dynamic Load Management (DLM) is meant to analyze a household's electricity consumption and allocate the power surplus to the EV charging infrastructure.

During the day, when multiple devices are connected ' charging will be slower, but as days are made for driving and nights for charging, at night your EV will have access to more power. This way you will be able to charge your EV day and night without increasing the power supply.

4. Which EV charging station should I choose?

There is a wide range of range of EV charging stations on the market, however these are important things to think about before making a decision:

  • Socket vs cable. If you are planning to charge your EV then it is very very convenient to buy a charging station already with integrated cable, will save you time and effort.
  • Smart features of the charging station. Does charging station come with communication and supports the smart features such as integrating with solar panels, power balancing, dynamic load management (smart charging), remote tech support and others.
  • Local technical support. Check whether there is a local representative of the respective brand, it will make it easier and faster to solve the problem if it even occurs.
