Summary: | The main categories of electric mobility are elevators and electric vehicles. The elevators are a reliable and convenient way of transport. The electric vehicles have been gaining global interest in the last years due to their capacity to reduce GHG and to their high efficiency. The electric bicycles are a convenient way of transport because they are small, reduce traffic jams and improve the rider’s health. The goal of the dissertation is to develop an embedded system capable of measure voltage, current and power from the electric battery of an electric bicycle, send data to a smartphone by Bluetooth, and from the smartphone to a computer using MQTT network. The system had to be developed under the IEEE1451 Standard. The methodology used was literature review of energymetters developed around the world; study of IEEE1451 standards; design of the system based on sensors, actuators and the communication between them and the processor; hardware development using mbed microcontroller, INA260 sensor, HC05 Bluetooth module and a SD breakout board; firmware development based on pooling, interruption, state machines and TEDS; Smartphone app development based on Bluetooth and MQTT networks; Management application development based on node connections using software NodeRed; Finally tests performance and results analysis. The system developed here may contribute to perform tests to verify the electric consumption, current, voltage and power of eBike in different conditions such as varying the cyclist mass, eBike mass, acceleration conditions, speed conditions, air conditions, slope degree and routes. This may allow to discover the most economical routes or trace the user profile. In this way, together with air pollution gas tracking and Photovoltaic eBike charging, this project may contribute to urban mobility sustainability and better quality of life. In comparison to the energy meters revised in the literature, the system developed here is integrated with the eBike and has lightweight. This makes the experiments easy to be conducted.
