Public Charging Operator, Bulgaria

A local charging operator runs a high-traffic public charging station along a major transport route in Sofia, Bulgaria's capital. The site serves a high volume of private EVs, taxis, and light commercial vehicles daily. As the number of electric vehicles continues to grow in Bulgaria, the existing charging infrastructure was no longer meeting user expectations for charging efficiency. The operator's goal was to expand fast-charging capacity at the site—improving user experience and increasing daily charging sessions without undertaking major grid upgrades.

The Challenge of Expanding Charging Capacity at a Public Site

For this public charging station, adding fast chargers was not simply a matter of installing more units. The site serves a diverse mix of vehicles—private cars, taxis, and light commercial vehicles—each with different charging interface and protocol requirements. At the same time, reliability is critical in public settings; any charging disruption can affect users' travel plans and damage the station's reputation. Additionally, the local grid has limited capacity, requiring careful load management to avoid impacting surrounding power supply when integrating new high-power equipment.

PowerBoost 100kW DC Fast Charger

SETEC POWER supplied six PowerBoost 100kW DC fast chargers for the public charging station, each equipped with dual CCS2 connectors to meet the site's demands for both charging efficiency and equipment reliability.

100kW Fast Charging: Significantly improves charging efficiency, effectively reducing user waiting times

Dual CCS2 Connector Design: Enables simultaneous charging for two vehicles per unit, compatible with European mainstream charging standards, covering private EVs, taxis, and light commercial vehicles

Dynamic Power Distribution: Automatically adjusts power output based on the number of vehicles charging simultaneously, preventing grid overload

Modular Design: Individual module failure does not interrupt overall operation, ensuring charging service continuity

Improved Service Capacity at the Site

Since the six fast chargers were put into operation, the site has seen a noticeable increase in daily charging sessions, with reduced queuing during peak hours. The operator successfully expanded fast-charging capacity without the need for major grid upgrades.
