Buying an electric point for charging at home offers many benefits however a major concern for many electric vehicle drivers is whether such an installation could incur additional costs or require a change of electricity contract. Fortunately, there are smart charging stations that allow you to maximize charging efficiency without having to change your electricity contract.
The home charging station with dynamic energy management
Domestic terminals equipped with dynamic energy management systems represent an innovative solution for electric car owners wishing to optimize charging time without increasing their energy costs.
Dynamic energy management allows you to check your home's electricity consumption in real time to redistribute it to your vehicle.
One of the key features of these charging stations is their ability to adapt to the constraints of your existing electricity contract without the risk of exceeding your subscription limit. This not only ensures that you don't have extra charges on your electricity bill, but also that your vehicle is charged efficiently and ready to go when you need it.
💡 What is the minimum electricity subscription to recharge with a home charging station in France ?
To make the installation of the electrical terminal profitable and benefit from faster charging than with a domestic socket, it is recommended to have a minimum electricity subscription of 9 kVa in a home with a single-phase installation and a minimum of 12 kVa for a three-phase installation.
The kilovoltampere (kVa) is the unit which represents the maximum load that an electric meter can support. This information is indicated on your electricity contract.
How does the electrical terminal with dynamic load shedding work?
Dynamic energy management is based on a simple principle which is to record in real time the energy remaining on the home's electrical network and to redistribute the remaining energy to the charging station. We are talking about automatic energy shedding, it is the act of measuring the current to reduce or increase the charging power of the terminal according to the available energy. This solution allows you to recharge a vehicle without worrying about your electricity bill with a maximum power determined by the subscription and which varies according to the energy available in the house. The more devices you have on and in use on your electrical installation, the less power you will have available for recharging your electric car, and vice versa when the devices are turned off.
For example, if you run a washing machine and turn on your oven, the charging station will reduce the charging power and then increase it once the appliances are turned off. This technology is very useful for nighttime charging when energy is often less required.
In addition, these terminals generally have programming features that allow you to define charging schedules based on your habits or off-peak hours defined in your energy contract. This allows you to schedule charging for times when electricity is cheapest or when energy is at its peak.
Programming from the electric vehicle also gives you added convenience and optimal flexibility.
Which terminals have dynamic energy management?
Here are the main terminals which allow automatic energy shedding:
- Velocy Box 7.4 kW with energy management system
- Velocy Box 22 kW with energy management system
- Wallbox Pulsar Plus Socket + MID Power Boost energy meter
- Wallbox Copper SB + MID Power Boost energy meter
- Zaptec with Zaptec Sense
- Schneider EVlink Home Smart
- Witty Start + ICT simulator
So that the terminal dynamically manages the remaining energy of the house, we generally find the load shedding module as an option or in the form of a kit.
Installation of a terminal with dynamic load shedding
The installation of a home charging station with a power greater than 3.7 kW requires the use of a qualified professional.
To recharge at a home charging station, the electrician will need to create a dedicated line, on which a load shedding module connected to the terminal will be installed. The module is positioned at the electricity meter, upstream of the charging station, to transmit information on energy consumption in real time and thus adjust the charging power delivered by the terminal to the vehicle.
An element to take into account when installing an electrical terminal with load shedding is the distance and thickness of the walls which separate the load shedding module and the charging station. The cost of the work varies mainly depending on the distance between them and certain modules cannot cover too great distances or walls that are too thick.
This installation is, in general, easy and quick to carry out by a professional. To start your project, don’t hesitate to tell us about it. You can also call on a qualified professional who will provide a personalized quote to install a controllable charging system at home.
Conclusion
The smart terminal with load shedding ensures that your vehicle is recharged using only available energy without exceeding the limits of your electricity contract. You control your home charging costs and thus reduce the costs associated with charging your electric vehicle. It offers everyday comfort by reducing charging time at home or by allowing charging to be scheduled at the best time. In addition, a charging station with charging control is a sustainable charging solution: by optimizing the use of energy, you help support the transition to cleaner mobility.
If you are considering installing an economical terminal at home , the terminal with dynamic energy management is ideal to benefit from these advantages!
