Planning: Project Design
The first step in implementing the project is designing the system architecture, which serves as the foundation for how the entire solution will function.
At its core, the system is composed of three main components:
Central Computer: A Raspberry Pi acts as the system’s brain. It gathers all data from the EV chargers, processes energy usage information, and makes real-time decisions to manage and distribute power efficiently. It ensures that the total consumption never exceeds the building’s electrical capacity.
EV Charger PCB: Each electric vehicle charger is equipped with a microcontroller. This board receives commands from the central computer and controls how much current is delivered to the vehicle, adjusting it as needed to balance load and prioritise vehicles with lower battery levels.
Wireless Communication Module: The system uses a wireless network to enable communication between the central computer and all EV chargers We are using a mesh system to ensure long distances or think walls that can disrupt the communication. This setup avoids complex wiring and allows for scalable integration in multi-residential buildings.
The system architecture is designed to be modular, autonomous, and adaptable, meaning it can operate without human intervention and can be deployed in different building configurations. This architecture ensures efficient power management, scalability, and a better user experience for EV owners.
