Remote Battery Monitoring System enforcing safety features in Electric Vehicles

As a consequence of the current developments in the automotive industry and especially in electric vehicle manufacturing, new legitimate aspects regarding the safety of people, systems and infrastructures must be addressed. The need for higher powertrain power density is driving battery voltages up to 1200 Vdc, which poses significant safety challenges. Fatigue and instantaneous loads on battery and high voltage components in the form of historical data can support OEMs' efforts to improve safety and production effectiveness. Therefore, it is essential to monitor vehicle batteries individually and acknowledge them when necessary. This paper describes a wireless monitoring system that collects battery data and transmits it wirelessly (LoRa/Wi-Fi/4G) to end users to inform them about battery status while also generating historical data about battery profile. The purpose of this application is to ensure safer battery practices (charging/storage/maintenance) by informing the end-user of any abnormal condition, as well as to store historical data that can be used for battery behavior analysis under different operating conditions. Finally, we present a practical example of this system applied by Energica Motor Company in the FIM Enel MotoE World Cup.
