The path to sustainable electric mobility depends on multiple factors such as reducing emissions, energy efficiency and conscious usage. This project presents itself as a contribution to the improvement of Electric Vehicle (EV) charging, with a positive impact from the moment of connection to the Energy Distributor (ED) until the EV charging finishes. The electric charging solutions for the residential market imply, in many situations, an increase in the contracted power to respond to an inefficient charging cycle that starts when the charger is connected and ends when the VE battery maximum charge fulfils. The increase in contracted power is not always the best solution for faster and more efficient charging. When single points of connection to the power grid are available, common to a group of tenants, it becomes harder to adopt electric mobility solutions. Managing the contracted power, optimising charging time, controlling costs according to the connected user, or even balancing the charging of EVs according to the source of energy at a given time, are challenges that the presented proposal contributes to solve. With focus on the residential market, this solution is suitable for both single-use connection points and shared connections, which are very frequent in apartment buildings without a closed garage or which, for other reasons, share the available electrical connections to the grid. The proposed architecture allows the use of one or several common charging points, applying a mesh network of intelligent chargers orchestrated by a residential gateway.
