As more and more cities and countries promote the idea of clean carbon footprint and sustain initiatives to improve the effects of climate change, electric mobility will also become more prominent. Or at least that’s what they say. Electric Vehicles (EVs) have generated a lot of interest in recent years, but this success still does not change the fact that only about 2,5 % of new cars sold globally in 2019 was electric.
Even though advanced technologies are being integrated in the improvement and development of EVs, battery and charging solutions causing deep uncertainty for potential consumers and making the used Electric Vehicle market almost non-existent. The possibility of battery damage in case of overcharging or deep discharging profoundly influence the concerns. To prevent the possibility of damage, EV batteries need a proper Battery Monitoring System (BMS) which provides precise State of Charge (SoC) data to owners and reduces the impact of uncontrolled charging. This could increase the battery lifespan, assure their reliability and protect the equipment they power.
What is AutoPi?
AutoPi is an advanced IoT telematics device built on an extendable cloud platform that securely connects vehicles to the internet. Due to its powerful networking abilities AutoPi can be configured to allow remote data monitoring, analysis, control and communication within electric vehicles to help improve charging efficiency and maximize the reliability of the energy supply.
AutoPi Battery Monitoring Feature
Optimal scheduling of EV charging is the essential key to extend the life cycle of the Battery Pack. If it is not done in advance, it will ultimately lead to battery failure. That is why the prime goal of AutoPi is to send detailed information of battery performance locally or remotely like driving power, estimated state of charge or flow of current (to determine if the battery is being charged) and help owners convert this gained information into practical routines that keeps the battery operating at the optimum level.
AutoPi Telematics Unit connects to the EV via OBD-II port and with minor configuration can read out vital parameter measurements like cell voltage or battery current and estimates the present capacity of the battery so the EV can be safely charged/discharged at appropriate levels. While monitoring usage profile and events, EV owners can predict the time when battery needs to be charged or can be discharged.
Further enhancement can be achieved, with a proper set up AutoPi can compute the battery capacity while charging/discharging and send warnings in case of possible malfunctioning occurs. AutoPi BMS log history of all measured parameters can be also analysed for future references on battery health in relation with the improvement of reliability of used Electric Vehicles.
Innovation in battery functionality has been the key motivation for AutoPi and to provide real-time accurate battery capacity determination for users that encourage smart charging. An easy implementation that might benefit not only private owners but also business or corporate investors in the sustainability of electric mobility.
