Which charger for a specific home installation?

We advise how to choose an electric car charger depending on the type of home installation and pre-meter protection. Check examples of electric charger installation in a garage, in a detached house, and a house with a shared garage.

Types of chargers depending on the power

• Single-phase 230 V chargers
  • 7 kW power, 1×16 A circuit fuse
  • 4 kW power, 1×32 A circuit protection
• 400 V 3-phase chargers
  • Power 11 kW, circuit protection 3×16 A
  • Power 22 kW, circuit protection 3×32 A

So, to choose a charger with the right power, you need to analyze two factors:

1. Type of home electrical installation
2. Type of pre-meter protection,

Pre-meter protection

It has been assumed that the pre-meter protection is also overload protection and it is selected depending on the power allocation. They are implemented on S-type circuit breakers (short-circuit-overload).

Standard pre-meter protections for supplying individual consumers are as follows:

• For 1-phase power, it is 1×25 A,
• For a 3-phase supply, it is 3x25A.    

If the recipient has the technical conditions of power supply (WTZ) for higher power, then a 3×32 A or higher pre-meter protection can be good to use.

So, when buying a home vehicle charging station, the customer must remember the current load, i.e. the current intensity in general, i.e. the current that will flow when the car’s battery is charging, and what circuit we have for the charger socket.

Electric car charging station design – what to consider?

Are you planning to build a home vehicle charging station? Find out what to consider when designing it so that drivers can use it comfortably and, most importantly, safely.

The possibility of charging the car with a public charger while working, shopping, or on the road is a great comfort for drivers. For this reason, more and more charging points are appearing in the urban space, e.g. in parking lots of shopping centers, under office buildings, hotels, as well as at gas stations on highways.

Designing electric car charging stations

If you are involved in the process of building a charging station, e.g. in an office car park or a local car park, you need to be aware that several key factors should be carefully considered at the stage of its design. The most important issues are:

• appearance and marking of the station,
• easy access to the charger,
• comfort and safety of using the charging station,
• The place where the charger is to be installed.

Let us now analyze the points mentioned in more detail. Below you will find the most important tips for designing electric car charging stations – check what to pay attention to at this stage of the investment.

Appearance and marking of the home vehicle charging station

Home vehicle charging stations should be designed in such a way that drivers can easily recognize them. You can mark them with expressive colors and provide them with appropriate lighting. A well-lit charging point will not only attract the attention of drivers but also make it easier for them to charge their car in the evening or at night.

Easy access to the charger

The availability of a charger is one of the most important issues that should be considered at the stage of designing a station and its security. Easy access to the station is crucial – ideally, the charging point should be accessible from any direction of travel.

 It is also worth adding that in the case of charging points in shopping malls and office buildings, the charging station should be located near the entrance to the building or elevator if it is planned to be installed in the underground parking lot.

The charging station should be easily accessible to every driver

Easy accessibility of chargers doesn’t just mean trouble-free access. When writing about availability, we also mean the possibility of using a home vehicle charging station by drivers of electric vehicles of various types – with different plugs and the different power of the built-in charger. In addition, when choosing a place for mounting the charger, you must remember that also disabled people must have trouble-free access to it.

Comfort and safety of use

For drivers to be able to fully comfortably charge their car, it is worth equipping the station with cables (thanks to this, the person using the charger will not need their cable) and cable holders. It is also necessary to ensure the safe use of the charger. When designing, it is necessary to take into account the location of protective barriers, speed bumps, or bollards to reduce the risk of accidental damage.

The design of the charging station should also take into account the fact that electromobility is still at an early stage of development, which is why many drivers still do not have much experience in using public chargers. Therefore, the whole process should be facilitated for them as much as possible.

Make sure that the instructions, information on charging payments, and the telephone number of the customer service person in case of difficulties with the operation of the charger are displayed in a visible place.

Location of the charging station

Choosing a charging point location is important for several reasons. The first is the issue of safety – following the applicable regulations, before choosing a place; you should make sure that there is no risk of explosion in the area. In addition, it must be checked whether the location of the home vehicle charging station in such a location does not pose any risk to other vehicles, pedestrians, or cyclists.

Charging an electric car in a cooperative block

What solution is good to use by drivers who do not have an underground car park? As we read on the forums, a popular method is charging through an extension cord connected from the apartment to the car. However, it is not a convenient or safe solution. Car manufacturers explicitly advise against charging via an extension cord due to the high risk of a short circuit.

In the case of cooperative buildings with an underground car park, the matter is simpler since these are always equipped with 230 V sockets. In theory, if the garage is part of a shared property, we can use them to charge the car if the manager has not decided on the prohibition of using them for purposes other than e.g. cleaning devices.

With infrequent, single charging, it won’t be a problem. If we wanted to charge the car in this way regularly, we would have to settle accounts and pay for shared electricity.

Own charger for an electric car in the block

What if we focus on the assembly of the home vehicle charging station? In the first place, we will have to obtain the consent of the housing community and the building manager, who should present the agreed technical requirements during the interview, as well as to conduct an on-site inspection.

In the case of preliminary approval, we can send an official letter to the administration with consent to cover all assembly costs on our own.

It will also be necessary to find a designer and contractor if such has not been indicted by the administration. At the design stage, it will be required to calculate the connection power of the internal supply line (WLZ), i.e. the cable leading from the connection to the main switchboard of the building.

 If the power consumption in the block is almost equal to the connection power or the reserve is too small to connect the charger, it will be necessary to ask the energy supplier to increase the connection capacity. However, we then have to take into account additional costs.

Electric car charger in a block of flats – benefits for residents and administration

From the perspective of both the cooperative and the residents, the consent to build charging stations for electric cars brings mutual benefits. The main advantage of this solution is its great convenience – drivers are not burdened with the need to commute to remote stations or use the aforementioned charging methods with the use of an extension cord.

 Moreover, thanks to the lower electricity prices in the night-time tariff, refilling energy becomes much cheaper, allowing you to enjoy a fully charged car in the morning without straining your pocket.

In this case, the cooperative can also gain a lot. The possibility of charging electric cars significantly increases the attractiveness of the building as a modern and environmentally friendly place, which translates into an increase in apartment prices and greater interest from potential tenants.

A home vehicle charging station with a meter will certainly help to save conflict situations between the residents of the community. Transparency as to costs and their distribution when billing for electricity will prevent anyone from feeling burdened with the costs of charging a car other than their own.

AC vs DC charging stations – what to choose?

Are you wondering how to supplement energy in your electrician? Is it better to choose a charger, or maybe a quick charging station? We explain the basic differences between AC and DC charging – check the advantages and disadvantages of both solutions and find out where each type of charger works best.

On the electromobility market, as in every industry, manufacturers are struggling to innovate their devices, but one thing remains unchanged here. This is the type of electricity we charge our electrician. Most of the currently produced electric vehicles are equipped with two charging ports, eg Type 2 and CCS.

The first one is designed for AC (alternating current), and the second is for charging with DC (direct current). Do many people ask what is the difference between these two ways to charge electric cars? and which one is better. Well, the answer to this question is neither clear nor simple.

AC charging – what does it mean?

AC charging stations for electric cars, often called chargers are primarily characterized by lower charging power. The word “home vehicle charging station” is good to use more often when such a device is installed in a private place). The charger is more often associated with private use in a single-family house.

From a technical point of view, the process of charging an electric car with this type of charger is less effective than the case of using a DC station. The key point is the fact that we do not charge the batteries directly with alternating current, but on the way, it must be “straightened” by the built-in charger.

This is one of the major disadvantages of AC charging as converters limit their power. An example is the Nissan Leaf. The manufacturer has placed a charger inside the car limited to 3.6 kW, which, despite the use of an 11 kW device, will not let such power through. However, charging with such power shortens the time by almost 50% compared to the 2.6 kW mobile chargers, which most electricians are equipped with.

DC fast charging home vehicle charging station – the principle of operation

When it comes to DC fast home vehicle charging stations, the process of replenishing energy is much simpler. The current goes directly to the batteries, with no restrictions on the way. In this case, the Nissan Leaf charging time from 0 to 100% can be reduced to less than an hour with a charging current of 50 kW.

Home wall box electric car charger

 The charging power of devices adapted to alternating current AC can be a maximum of 22 kW, but the differences are visible in the structure itself. That we can see in the case of a wall box or a free-standing charger. DC stations in the world of electro-mobility are easy to compare to Formula 1. They are very efficient and effective in the charging process, and thus – quite expensive.

How to charge an electric car at home?

Are you thinking about buying an electric car and want to learn how to best charge it at home? We present several ways to charge an electric car at home – learn about the advantages and disadvantages of each of them.

Electric car charging at home

Although the publicly available charging infrastructure for electric cars in Poland is gradually being developed, access to a private charging point at home is very comfortable for every driver. Equipped with the appropriate accessories, you can conveniently charge the car in the garage or a parking space overnight (or less depending on the available charger).

In the morning, the car will be ready for the road, and without the stress of a quick battery discharge; we will be able to go even on a longer route. This way, you can also save time (and money) searching for and charging your car at a public station.

Domestic vs Commercial vehicle charging station

Of course, you have to reckon with the fact that refilling energy at home will take longer compared to charging the vehicle at a public point – regardless of which charging method you choose. Commercial chargers usually have more power, and this significantly affects the charging time of the car.

However, in this case, the extended replenishment time should not be too much of an inconvenience – as a rule, when charging the car at home, we connect it overnight. It is also worth adding that it is a cheaper solution than replenishing energy in publicly available chargers.

There are several ways to charge an electric car at home. These include charging from a socket in the garage or refilling energy using a free-standing charger or wall box. Each of these methods is briefly described below.

Charging an electric car at home

Basically, charging an electric car at home can be quick, easy, and relatively cheap if you choose the right charger

Charging an electric car from a socket

Seemingly, it is the easiest and least demanding way to charge an electric car. In this case, apart from the appropriate cable that we connect to the plugin of the vehicle, we do not need any additional accessories in the form of chargers. We also do not have to invest in the reconstruction of the garage to adapt the wires in the home electrical system.

A standard socket in the garage indeed is enough to replenish the energy in the car, but it is definitely not the most efficient, and certainly not the fastest solution. At first glance, it may seem attractive due to the low cost and simplicity of the entire charging process. However, the main disadvantage of this method is the time it takes to refuel the car.

Installation of domestic home vehicle charging station

You have to be aware that the power of a single-phase 230 V household socket is very small. Using the mobile charger that comes with the car, the power of which often does not exceed 2.4 kW, fully charging the battery can take up to 20 hours, depending on the model of our electrician, which certainly puts off many drivers.

 Of course, the fact is that we do not always fully charge the car. In such situations, we can replenish our energy to a satisfactory level in a shorter time.

Charging an electric car with a special home charger

Chargers dedicated to electric cars allow you to charge the car in a much shorter time, compared to home sockets. Depending on your needs, we can choose a free-standing charger designed for installation on a garage wall or the external wall of the building.

Unfortunately, you cannot ignore the fact that the purchase of an electric car charger is a larger investment. In addition, in the case of 11 kW chargers, it may be necessary to make changes to the home network.

 Some chargers of this type use three-phase power and it may turn out that the current installation is not able to accept such a load. Of course, such modifications will not always be needed. In-home conditions, chargers with a power of up to 7.4 kW also work very well.

 They can freely use a single-phase power supply while allowing faster charging than mobile chargers. Of course, each time before choosing a charger, it is recommended to consult an electrician. A specialist will advise us on the best solution depending on the quality of the home network.

We know from our own experience that despite the higher costs and possible changes in the home electrical network, the investment in an EV car charger is extremely profitable. Depending on the power of the charger (both the one built into the car and the home charger), the time needed to charge the car may be reduced several times! The promise of saving time convinces many drivers to make such a purchase.

Location of the charging station

Choosing a charging point location is important for several reasons. The first is the issue of safety – following the applicable regulations, before choosing a place. You should make sure that there is no risk of explosion in the area. In addition, it must be checked whether the location of the station in such a location does not pose any risk to other vehicles, pedestrians, or cyclists.

It is also worth mentioning the additional functionalities that the chargers are equipped with. Here are a few of them:

• specialized software that allows you to select the power with which the vehicle is to be charged,
• anti-voltage, residual-current, and overcurrent protections,
• monitoring energy consumption and car charging status,
• the ability to control the charger using a mobile application.

To sum up, the purchase of a home vehicle charging station is a very good solution if we charge the vehicle frequently and we want the energy to be refilled efficiently. Let us add that home chargers are very easy to use and allow you to charge the car in a completely safe way.
