Recently, there has been a big boom in electromobility, with car companies racing to showcase new pure electric or hybrid passenger car models. There is also a development of other electrically powered means of transport - electric motorbikes, electric bicycles, electric scooters and so on.

As the number of electric vehicles in operation increases, so do the requirements for the densest possible network of charging stations. Charging stations are now becoming a common feature of public car parks, car parks at apartment blocks or shopping centre car parks. Each location has specific charging requirements - at a petrol station we need to charge quickly and drive away, at a shopping centre charging may take longer but needs to be available for a larger number of customers at the same time.

Research and development in the field of charging stations is carried out at the Faculty of Information Technology of Brno University of Technology in cooperation with KPB Intra s.r.o. from Bučovice, a traditional manufacturer of instrument transformers. KPB Intra s.r.o. has decided to expand its product portfolio to include charging stations, the development of which it has been intensively engaged in since 2015, and a team from the Faculty of Information Technology is behind the development of control and user applications.

The developed applications allow convenient use of charging stations for both end customers and easy management of the charging station network of commercial operators. The entire system includes modules for managing individual charging stations, allowing to set individual prices and station locations, to monitor the activity and status of individual stations. The system also includes modules for managing the operator's contractual clients, setting individual prices for users, a complete billing system and templates of documents required for charging station operation according to the current legislation. In addition to contractual recharging, one-off recharging is also possible by purchasing an e-voucher with a credit. The charging stations also allow the display and remote editing of the advertising loop and other useful functions.

The developed software is flexible enough to be part of the entire charging station portfolio, which currently includes two basic types: the AC Business charger Twin 2x 22 kW (AC charging station designed primarily for public car parks, shopping centres and other places where fast charging is not required) and the DC Business charger DC 50 kW AC 22 kW (combined DC and AC charging station suitable for places with faster charging requirements).

Researchers from the Faculty of Information Technology have thus contributed to the creation of a sophisticated system for charging electric cars and thus supported the further development of this environmentally friendly mode of transport. The developed system continues to be developed based on comments from both users and operators of charging station networks.
