Tesla's Smart Charging - Client Case

Green Energy In Mobility


Matching supply with demand of green energy in mobility. For some time now, energy supplier Eneco has been providing an application for owners of electric cars that matches supply with demand in the domain of green (wind and solar) energy. Xpirit created the underlying cloud architecture, which, in conjunction with Microsoft Azure technology, played a decisive role in the project’s success.


Using their mobile phone, owners of electric cars – initially only Tesla, but shortly also other brands – should be able to determine when their car needs to be charged, while a “SlimLaden” (SmartLoading) web application finds out the cheapest times. To this end, the application needed to bring together a number of details: the user’s settings, such as the time by which the car’s battery needs to be fully charged; the rates, which, in principle, are adjusted every fifteen minutes; the details of the vehicle, such as how full the battery is at any given time. Based on this information, “SlimLaden” should determine how many time units are required to ensure that the battery is fully charged when the user is ready to embark on their journey.


  • Building a superb cloud architecture that served as the vital foundation for the development of SlimLaden.
  • Solid architecture playing a pivotal role in rapidly ensuring a high-quality result in an innovative environment.
  • Being an authority on Microsoft Azure technology, Xpirit managed to develop and implement the application in less than three months.
