Public transport operator MZK in the Polish city of Zielona Góra is planning to electrify 47 buses – 60% of the city’s fleet – and has chosen local firm Ekoenergetyka-Polska to supply the charging infrastructure The 4-million-euro project is the biggest of its kind in Poland.
MZK will deploy multi-output e-bus charging stations at 11 bus termini. The stations, each of will provide a power level of 400 to 800 kW, will power a total of 29 automated pantograph charging points. The chargers will be equipped with intelligent dynamic power management – each station can charge multiple buses at the same time, or provide the full charging power to one bus to shorten charging time
The city will also deploy 28 lower-power charging stations for night charging. Each of these will charge via a Combo 2 plug and will deliver between 40 kW and 80 kW. These stations will also be equipped with dynamic power management.
The new stations will follow international charging standards, allowing them to be used by buses from different brands. Ekoenergetyka-Polska will also deliver a fleet and infrastructure monitoring system.
“This was the biggest single public tender for e-bus charging stations in Europe, and the first project where a complete city-wide charging system will be deployed,” said Ekoenergetyka CEO Bartosz Kubik.
