Smart charging points: the best option for your residential complex

Electric vehicles are becoming more and more widespread, leading to the need for smart charging points to ensure operation. These charging points can be installed in a wide range of places, including the residential complex in which you live.

Where to charge an electric car

The electric vehicle has arrived, and is destined to play a major role in vehicle fleets in the not too distant future. Adaptation to this new type of vehicle must therefore start now. Just as with fuel-powered cars, electric cars need to be topped up. Charging points –which are becoming increasingly commonplace in cities– are therefore essential.

These points from which to charge your electric car can be located indoors or outdoors and can be either private top-up points or part of a public network. In this regard, an excellent option for your residential complex would be to install a smart charging point where sustainable vehicles can top up their batteries. You will be able to charge your vehicle every day without any problems.

What are smart charging systems?

What exactly are these systems? These charging points allow vehicles to be topped up efficiently. The system combines an electric charging unit with a series of parameters to ensure the vehicle’s battery is topped up at certain times of the day. It is a smart system, which charges batteries based on the cost of electricity throughout the day or at times of lower electric consumption in the building.

Furthermore, this smart charging system keeps track of which users top up their vehicles at the charging point and how quickly each electric vehicle must be charged. These points are ideal for charging your electric car.

Benefits of installing a charging point in your residential complex

You may ask what use a charging point is in your residential complex if there is already a public network. Public networks are not yet very widespread, meaning a top-up point such as this ensures your vehicle can be charged every night. In fact, by morning it will be fully charged and ready to use.

Moreover, the smart system is equipped with user identification to prevent unauthorised use. It should also be remembered that having a charging point in your residential complex will avoid the need to queue up and wait at public top-up points.

As you can see, electric vehicles are the future and require a place to recharge. Smart charging points are therefore an excellent idea in all residential complexes. Do not hesitate to contact us if you would like more information or advice.

CEM-C. Electrical energy meters with built-in communication
Complete solution for energy consumption management

The meters in the CEM-C series are units for assembly on DIN rail, designed to take electrical energy readings. They can be used to manage energy consumption information for any type of industrial, commercial or production line facility. The units can report all information to our PowerStudio SCADA system via RS-485 communications (Modbus RTU) in order to prepare and automatically send simulated electricity bills, thus allowing energy costs to be distributed among different users. Moreover, the units report the electrical variables required for complete management of the facility.
Anti-Fraud System
All CEM-C energy meters are fitted with an anti-fraud system which uses sealable covers to prevent any tampering with the wiring. Moreover, all the units accumulate the power in a single log, preventing erroneous readings due to incorrect wiring or attempted fraud.
More than just energy metering
CEM-C units can also be used as power analyzers and installed in facilities with direct or indirect connection, depending on the model. Not only do they manage active or reactive energy, they also measure voltage, current, power, cosφ and other electrical variables in order to check that the facility works correctly.
CEM-C energy meters are designed for energy sub-metering applications. All CEM-C meters are designed according to current regulations for billing meters (IEC 62052- 11, IEC 62053-21 and IEC 62053-23). The main applications of the CEM-C range are: Airports, Large-scale infrastructure, Shopping centres and major retail outlets, Hotels and industry.
  • Multi-user supplies requiring brokendown cost allocation.
  • Control of manufacturing costs by calculating the energy cost for the final product.
  • Allocation of energy, manufacturing hours and CO2 emissions per facility or production process (for CEM-C21 and CEM-C31 only).

Do you know how to compensate instantaneously without worrying about harmonics?

For all those installations where it is necessary to compensate instantaneously reactive energy, both inductive and capacitive without the need to install power capacitors, the solution is SVG series (Static Var Generator).

There are very particular cases where conventional capacitor banks cannot compensate the totality of the installation's reactive power or are not able to work properly due to network characteristics. The new SVG devices are capable of compensating instantaneously reactive energy in order to make an accurate adjustment of the cosϕ, avoiding penalties in the electric bill for both excess reactive inductive and capacitive energy (depending on the tariff system of each country).

The principle of operation of a Static Var Generator is to inject current in the opposite direction to that consumed by the installation, adjusting the cosϕ instantaneously, with a response time of 20 ms. In this way the device avoids the installation of power capacitors and all possible resonance effects in the network (increase of THD% level) that can damage the components of the installation.

This makes SVG ideal for its installation in situations where conventional equipment cannot compensate or work properly:

  • Installations with fluctuating loads
  • Installations with capacitive loads
  • Installations with unbalanced consumption (difference in consumption on each phase)
  • Installations with high harmonic distortion levels (THD%)
  • Lines with constant voltage fluctuations

New needs in the sector

The new CVM-E3-MINI analyser is specially designed to carry out the best electrical and energy variable management in any type of installation, adapting to new international standards for measuring and managing energy efficiency.

In line with the latest international standards, such as European Directive 27/2012/EU or National Electric Code 56/2016 (in Spain), the unit provides the user with the level of CO2 emissions of the installation, line or machine, as well as the monetary cost of the energy consumed or generated in each situation.

Check each parameter of your electrical installation
Everything that you need to know about your installation
  • Measures and calculates any parameter in your electrical network
    The CVM-E3-MINI provides real-time measurements of more than 250 electrical parameters, including energies, cost and emissions, both in terms of consumption and generation. The unit measures the maximum and minimum RMS values of any instantaneous variable, as well as the harmonic breakdown up to the 31st harmonic.
  • Separates the consumption of two sources of energy
    The unit features a digital input for changing the tariff. In this way, the unit is able to save the incremental values of two sources of energy, either from the electrical network or the auxiliary energy generation system (fuel generator or UPS).
Manages your installation

It measures the operating times in order to carry out the necessary preventive maintenance of the elements of the line or machine in which it is installed. In this way, the person in charge of maintenance is able to replace all elements that could cause faults before they occur, preventing production line downtimes and the indirect costs associated with this.

The device features a transistor output for interacting with the system once an alarm associated with an instantaneous parameter appears, fully programmable by the person in charge of maintenance.

Prevents configuration errors
The unit can be configured via the free software PowerStudio. This software also allows any wiring issues on the device to be resolved remotely, without having to wait to stop production, thus avoiding erroneous data in the readings.
  • It resolves current transformer installation errors
    If a current transformer has been installed incorrectly, the unit will provide incorrect measurements. Using the software, it is possible to rotate a transformer without having to physically modify the wiring, thus avoiding reading errors and any electrical risk, as it is not necessary to interact with the power system.
  • It resolves voltage and current correspondence errors
    If the voltage connections are not on the same line as the current transformers, the unit will show erroneous values in the cosφ and power factor measurement, resulting in an erroneous power and energy reading. Via the software, it is possible to change the position of the voltage phases so that they correspond to the current phases without having to physically modify the wiring, thus avoiding reading errors and any electrical risk, as it is not necessary to interact with the power system.
Increased safety
The new CVM-E3-MINI features a new Plug&ON system with plug-in terminals to facilitate the installation of the device. These terminals are totally protected by sealable terminal strip covers to avoid any tampering or accidental disconnection due to the voltage of the wiring itself.

Increased safety

More versatility
The unit features an integrated Modbus RTU and BACnet protocol, providing versatility in terms of its installation in different types of installations, both in buildings and in industry settings. For those installations in which it is necessary to install the unit in panel format, the CVM-E3-MINI features a 72x72 mm adaptor for any assembly requirements.

More versatility

The best visibility
It ensures the correct display of data for distances of up to 3 m, avoiding having to open the panel to check any electrical parameter.


The best visibility

"Without a doubt, the new image of the CVM-E3-MINI power analyser from CIRCUTOR
is in keeping with current times and its features also respond to the needs of the sector."

Do you know how to detect electrical fraud in an agile, cheap and simple way?

the device allows you to compare the incoming current of any home with the outgoing current from the billing meter, detecting immediately any type of anomaly or fraud that may exist.


The three pillars of energy transition

Energy transition is a necessity rather than an obligation; to meet climate targets we must move towards a sustainable energy model that promotes the use of renewable energy sources.

Industrialised countries generate most of their electricity from conventional power plants, such as coal, gas or nuclear. These plants provide a huge economic benefit for the generating companies, where users pay for their energy needs by buying electricity and fuel from the relevant public utility companies. This form of supply is easy to use but often entails high costs and is quite inefficient in terms of the rational use of energy.

Energy transition is difficult but not impossible; the first step is to change the way energy is generated. For this, the generation points have to be decentralised. This energy model is known as Distributed Generation (DG). This system is based on generating energy at the same point where it is consumed, directly reducing network losses, which contributes to environmental preservation through the use of renewable energy sources.

Distributed Generation has multiple advantages compared to the conventional system, offering technical, economic and environmental benefits.


It improves the quality of the electric service because it reduces the probability of failure due to downed high-voltage power lines, as the percentage of use of those lines is reduced.

DG systems are modular and give the electric power distribution system flexibility. This means simple installation in a short time. It also provides the operating system with a great advantage, maintaining the flexibility of its total capacity, increasing or decreasing the number of modules.

DG reduces energy losses in the distribution and transmission lines. 


It avoids investment costs in transmission and distribution, generating a lower cost in electrical infrastructures and thus achieving operation and maintenance savings.

It reduces fuel costs due to improved efficiency in the case of cogeneration applications. These systems use waste heat for reuse in heating, cooling or to increase their efficiency by generating electricity, saving primary energy.


It reduces the emission of pollutants. DG favours self-consumption using in situ generation systems. This helps to reduce the consumption of primary energy from conventional sources by generating cleaner energy, like that from a photovoltaic system, and avoids emissions generated due to transmission losses from power plants to cities.

These systems can include multiple generation and storage systems, allowing generation by conventional systems to be shifted to solar or wind generation.

However, to achieve energy transition, it is not enough to decentralise the generation points and make use of clean energy sources, the way energy is consumed also needs to be changed. Therefore, success lies in changing consumer awareness and making rational use of energy resources.


Reducing energy consumption is based on the following three key pillars:

Electrical Energy Efficiency

This is the reduction in the power and energy required from the electricity system without it affecting normal activities carried out in buildings, industries or any transformation process. An electrically efficient installation enables its technical and economic optimisation, or rather a reduction in its technical and economic operating costs.

In short, energy efficiency involves:

  • Helping the sustainability of the system and environment by reducing CO2 emissions through optimisation of the energy demand.
  • Improving the technical management of facilities by increasing their efficiency and avoiding production downtimes and possible failures.
  • Reduction in both the economic cost of energy and the operation of facilities.

Electrical Energy Efficiency

Electric mobility

Energy transition is not possible without electric mobility; the electric vehicle is the future. Transition to the electric vehicle means a drastic reduction in greenhouse gas emissions. You only have to think about the difference in efficiency of a combustion engine and an electric motor.

An electric motor has an efficiency of around 95%, whereas a heat engine has an efficiency of around 30%. To travel 100 km, an electric car consumes three times less energy than a conventional vehicle.

This is based on the premise that the energy used by electric vehicles can come from clean sources, whereas the energy used by a conventional vehicle can only come from fossil fuels.

Electric mobility

Nearly zero-energy buildings (nZEB)

Consumption in buildings constitutes 40% of Europe's total energy. Reducing consumption in buildings is one of the main points of action to reduce energy dependence and thus comply with international agreements to slow down climate change.

This was the reason behind European Directive 2010/31/EU, on the energy efficiency of buildings, under which all member states must take steps so that as of 2020, all new buildings have nearly zero-energy consumption (2018 for public buildings).

Nearly zero-energy buildings nZEB have a very high level of energy efficiency and comfort, and very low energy consumption, coming mostly from renewable sources in situ or the environment.

Nearly zero-energy buildings (nZEB)

In short, energy transition involves a series of complex challenges to be addressed but, if managed properly, the benefits of the new energy model will help to halt climate change and improve everyone's quality of life.
