Smart Energy Meter for Electric Vehicle Based on Bluetooth and GSM Technology

摘要

Smart Energy Meter (SEM) has been successfully built for power consumption billing system of battery charger on electric vehicle based on bluetooth and GSM technology. The SEM has been tested using battery charger on electric bicycle as a load. Interaction between the customer (electric bike user) to the SEM is conducted by applying bluetooth and GSM. Duration time from customer requests to the SEM and SEM response is less than 1 minute. Communication between customer to the SEM is monitored by operator via SMS service from the SEM. Android-based application is built for bluetooth communication between the customer or operator to the SEM. The voltage and current measurement errors is reduced by the operator through unique code via bluetooth. Measuring errors are obtained at the values of 0.04% and 1.39% for voltage and current, respectively. THD on the current from the battery charger on an electric bicycle is too high at the value of 68.68%. Moreover, customer data and billing information are stored on SD Card storage media.
