Technical Architecture
How the System Operates
The embedded system follows a sophisticated operational workflow designed for reliability and precision in electric vehicle charging management.
-
Signal Reception
When a start signal is received, the ESP32 microcontroller processes the command and activates the contractor/relay, initiating the charging process for the connected electric vehicle.
-
Power Measurement
The PZEM-004 current sensor continuously measures the electrical parameters (voltage, current, power, energy) flowing through the system, providing accurate real-time consumption data.
-
Intelligent Control
The system automatically manages the charging session, stopping operation when a stop signal is received, manual unplugging is detected, or subscription expiration occurs, ensuring safe and controlled operation.
-
Data Transmission
Upon session completion, usage data collected from the PZEM-004 sensor is securely transmitted to the remote server for billing, analytics, and subscription management purposes.
