Smart electric vehicle charger

Electric motor or plug-in hybrid charger devices are used only to charge electric motors. In the case of indoor use, if the connecting cord is not connected directly to the socket (a simple form of vehicle charger), these are usually mounted on the wall of the house, at a distance from the vehicle park.

Although the installation of the equipment is not very complicated, it is always recommended to be done by a licensed licensee. Once installed, simply connect the vehicle cable to the socket. Depending on the type of battery, the vehicle itself selects the charging power to make it safer.

There are many different types of electric vehicle chargers.

BESEN reviews their status and finally, we describe the request we make to our clients who are interested in taking the device along with their photovoltaic system.

Types of electric motors depending on the connection

According to the type of connector, there are mainly 5 types of electric vehicle chargers:

•       Shuko connector
•       Type 1 connector
•       Type 2 connector
•       Combined single connector
•       Chademo connector

Schuko connector

So-called schuko connectors are traditional household plugs, the same ones we use for appliances. The main advantage of these plugs is that they are compatible with all types of electric vehicles. However, this is not the best way to charge the vehicle as charging is very slow.

Type 1 connector

The type 1 connector is the first connector made specifically for charging electric vehicles. It is also known as Japanese or yazaki. This model is a single-phase and can support two load levels in ac.

Type 2 connector

Type 2 connectors, also known as MENNEKES, are the most widely used connectors in Europe. It was called MENNEKES after the german brand that first made it. These devices are suitable for single-phase and three-phase installations.

Combined single charger

Unlike other chargers shown so far that use ac charging, the unique combined EV charger uses both ac and dc charging.

Chademo charger

This smart ev charger, while less common, is the most versatile. It is a three-phase charger that uses a high-speed direct current. Plus, it’s bi-directional, meaning the vehicle can be the electricity provider if needed. It is more common in Japan. In fact, the name of the charger is that of a Japanese association that integrates some of the most important vehicle brands in the country.

Other types of connectors

In addition to these already “classic” chargers, we may see more developed technologies in the future, such as wireless charging of electric vehicles. This is done by induction or magnetic resonance.

Vehicle charger by charging mode

•       In addition to the type of connector, chargers are also classified by charging method.
•       In this case, we find the following chargers:
•       Mode one
•       Mode two
•       Mode 3

The mode 1 charger is an outdated system and is no longer in use because it has a high risk of overheating. Electricity flows directly from the socket to the vehicle, with no control unit in between.

Mode 2 differs from mode 1 in that it has a charge control unit that cuts off the power when an abnormality is detected. It could also be used in hybrids, not just electric vehicles.

Mode 3 has the most advanced technology. In this case, the cable is not plugged directly into a home outlet, but a wall box must be installed on the wall. This ensures intelligent load control. It’s also compatible with plug-in hybrids. The brand of EV charger we use in our PV installations is mode 3.

And finally, there’s mode 4, which doesn’t work for hybrids, only for electric vehicles, which is the way charging stations in public places are usually charged.

Power-based vehicle chargers

Finally, regarding the type of charger, it is also divided according to the power it has, which determines the charging speed. However, the maximum charging capacity will be limited by the power of the charger and the power of the home contract. In other words, the contract power or the power of the solar inverter and the size of the PV installation, if any.

In this sense, there are the following chargers:

•       Up to 3.7kw
•       7.4kw
•       11kw
•       22kw

Electric vehicle chargers we’re betting on

Now that you know the types of EV chargers, before talking about the profitability of evs in the context of self-consumption, we’ll review our advice to our customers. Electric vehicles and self-consumption: the perfect combination

We are committed to EV chargers for several reasons:

They are a form of transport that produces zero emissions.

European legislation is steering society towards electric options for vehicles.

Our own facilities make domestic charging of electric vehicles particularly profitable.

If charging is done during the day, the cost may be zero. Self-consumption systems continue to provide greater profitability with overnight charging,

Also, if the house has solar cells, the savings will be even greater, as the electric vehicle can be charged with the energy stored in it at any time of the day.

Cost to charge an electric vehicle

So, how much will it cost us to “fill up” an electric vehicle?

According to our research, if you have a system for your own use, the cost of riding an electric vehicle is 0.01 euros per kilometer. Comparing our data with data from a study, we infer that riding in an electric vehicle is 12 times cheaper than a gasoline-powered vehicle.

In conclusion

Electric vehicles are the future of mobility. Over time, technology advances, these start to have more and more autonomy, and charging solutions start to become more comfortable and commonplace. It’s only a matter of time before gas vehicles are given up.
