Electric Vehicles (EVs) are increasingly becoming an alternative for road transportation due to their potential environmental benefits and the depletion of carbon-based fuels resources. However, a wider application of such EVs still needs to overcome several technological barriers, many of them given by limitations in charging infrastructure. Such charging infrastructure, is mostly given by chargers. A charger is a device that provides electrical energy from the grid (i.e., AC) to the vehicle (i.e., AC or DC). Large scale deployment of chargers is limited not only by economic constraints but also by limitations in the grid capacity. One strategy to deal with the grid-capacity limitation consists of dynamically allocating the time slots when chargers are connected to vehicles. This is commonly known as charger scheduling. Charger scheduling requires (among other things) knowledge of the charging time of each vehicle. The total charging time of a vehicle will then determine how long a vehicle will be connected to a particular charger. A precise estimation of the charging time is therefore crucial for an efficient assignment of chargers to vehicles. The charging time of a vehicle is influenced by many factors such as different energy requirements, battery capacity, input power, temperature, etc. Further, batteries degrade over the years (i.e., age) yielding to undesired side factors such as reduced capacity or increased resistance. Therefore, battery ageing also has an impact on charging time.

What will be your role?

The purpose of this assignment is to use machine learning approaches to create a model that can predict the charging time of a vehicle. The approach must take into consideration all the relevant factors that influence the charging time (e.g., required energy, battery capacity, etc). Further, the approach must also be able to continuously learn with the latest charging data, such that the charging time is corrected as the battery ages.
The assignment covers the following tasks:
  • Dataset generation with different battery models/ages/charging strategies.
  • Continuous-learning algorithm implementation with and without battery ageing correction.
  • Algorithm testing, quality of prediction comparison with and without ageing correction.
  • Reporting writing.
  • Final presentation to colleagues.
