EV charging automation system
- Enterprise, Logistics
The use case
Hungarian Telekom (subsidiary of Deutsche Telekom) planned to provide EV charging possibility in their office parking lots. But the power available at the electric distribution board was limited, and expanding the electrical input was extremely expensive.
They were seeking for a solution to manage queues due to significantly less charging stations than cars in need of charging.
The solution they imagined contains charging reservations, calculation of the optimal charging schedule, and controlling the output of the charging stations (which cars are charged, in which order, and how much power they get).
The solution
Our company had been working with Lurel Ltd. to develop a software solution which contains a web based platform, a mobile app, and an API. The functionality includes
- an API to the fleet management system to obtain relevant master data, and planned travel scheduling of certain cars.
- a web based back office for managing master data, reservations, and to check charging statuses, as well as potentional failures of the stations. It's also a
- a mobile app for ad hoc reservations, and for the possibility for employees to monitor their car's charging status. It's also a communication interface (for alerts, notifications) between the sceduling module and the user.
- a robust scheduling and energy management module, which uses different charging strategies (FCFS, economic, green) and several parameters (vehicle arrival and planned leave time, planned travel distance, weather conditions, vehicle importance, input limits of the car’s inverter, electricity price fluctuations, etc.) to calculate the optimal charging schedule, and controls the output of the charging stations.
The result
The solution had been implemented at the Telekom’s central office in Budapest.
