We parked, plugged the car into the ev home chargers and, while the battery charges, we took the opportunity to have a coffee, enjoy the scenery or send it on our cell phone….
This is an increasingly common scene, where the installation of charging stations for electric cars is booming, following the market for electric cars.
In the next five years alone, the national fleet of electric and hybrid vehicles should grow from 300% to 500%.
To give you an idea, Bloomberg New Energy Finance estimates that, by 2040, the world fleet will jump from 2 million to 56 million electric vehicles.
It means that, in two decades, the number of electric cars circulating in the world must surpass that of conventional vehicles.
Naturally, the consequence of this mobility revolution is the multiplication of ev home chargers. It is to power all these electric vehicles.
Charging points are multiplying in residential condominiums, shopping malls, supermarkets, gas stations and companies in the most varied sectors, which install electric vehicle charging stations for their own use or as a benefit to their customers and employees.
That’s what we’ll see in this post, which will show you everything you need to know about:
To have your own charging station, you will need two essential things. The first one is to acquire an ev home chargers that meets the standards
What we call here “charger” is the equipment also called “electric vehicle power system” – save, used to supply energy to the electric car.
The charger/save is the part that contains the software and control functions for charging electric vehicles.
Be careful when shopping! In addition to meeting international standards, the charging equipment must be compatible with the plugs of the most used electric vehicles.
Furthermore, electric cars almost always require more than seven kilowatts of energy to charge. You will need ev home chargers.
Therefore, both the chosen chargers and the electrical infrastructure must meet this need efficiently and safely. The second thing you will need to do is hire an electrical engineering company or a specialist to assess the condition of your electrical installation.
Based on this assessment, the electrical engineer will design the adjustments you will need to install the charging station.
This is because electric vehicle charging stations need their own:
In addition, the electrical installation of the charging station has its own infrastructure of conduits and junction boxes. And this will have to be projected foreseeing future expansions for the acquisition of ev home chargers.
Ideally, you will be accompanied by specialists from the assessment to the purchase of the charging equipment, passing through the necessary clearances with your local electric power company for the installation of the charging station.
In addition to these, each state may have specific rules for installing electric car charging stations.
According to the operator, the installation of the charging station must be designed by a specialist contemplating some specific rules. Between them:
Have an exclusive circuit for each charging station. Overcurrent protection device provides protection against electric shocks. You need to follow the guidelines of the suppliers/manufacturers of charging stations”.
The power distribution boards that supply electric vehicle charging stations must contain ev home chargers.
Charging stations must be designed so that their activity does not cause disturbances to the electrical system of the local distributor.
In addition to meeting national and regional standards, the designer will be instrumental in adapting the electric vehicle charging station to the voltage standard of the building or the local electrical network.
Typically, ev home chargers stations are manufactured to operate with voltages of 380/220 V or 400/230 V.
But these values can be too high or low for the voltage used in the building where they will install or in the electrical network where they will be connected.
For example, if your company operates on 127V and the charging equipment is 380V, a transformer will be needed to raise the voltage at the charging point.
In large stations, with several charging points for electric vehicles, the voltage pattern is easy to change with the local electricity distributor, as we will see later.
Residential or commercial buildings can install electric vehicle charging stations of three types:
Choosing between them depends on the specifications of the ev home chargers and the voltage standard of the local electrical network.
Fast charging stations are the most expensive. They operate in direct current with high power. And they are easy to install in places that receive electricity in medium voltage (13.8kV and 34.5kV).
That’s why they are suitable for short stopovers, such as gas stations on highways, convenience stores or shops. On the other hand, semi-fast or slow charging stations cost less and operate in alternating current.
Normally, charging stations for collective use – such as shopping malls, airports, supermarkets or gas stations – use ev home chargers.
Private stations, residential condominiums and places where the car can be stopped for longer, such as companies, for example, usually opt for slow or semi-fast charging.
In addition to the time vehicles can remain parked and the type of electrical energy voltage, the choice of chargers must also consider the compatibility with plugs of the most used electric cars.
Typically, a car with a 25 kWh battery packs takes:
