SoC Estimation and IoT based Delayed Charging of Electric Vehicles

The fossil fuel crisis and increased pollution by internal combustion engines have forced to bring back decade old Electric Vehicle (EV) technology. The heart of EV is its battery and its life management is having crucial role in the longevity of EV. The aging of EV batteries is unavoidable and care has to be taken to reduce the aging. One of the main reasons for aging is that EVs are left unused with high State of Charge (SoC) i.e., calendar aging. In this paper delayed charging technique is incorporated in-order to reduce calendar ageing. The Internet of Things (IoT) technology is used to implement the delayed charging in this proposed framework. The combination of Open Circuit Voltage (OCV) and LTC2941 based Coulomb Counting method of SoC estimation is used here. The proposed methodology is validated with hardware setup and Blynk app-based results.
