The aim of the projekct is to examine the usability of battery systems “free capacity” for the provision of ancillary services. The subject of research is battery systems that are primarily installed for a purpose other than providing ancillary services (eg for peak-shaving in fast charging of electric vehicles, or load-shifting PV). This project is co-financed with the state support of the Technology Agency of the Czech Republic within the Theta Program. The contents in brief:

 Business analysis of ČEPS (TSO) requirements and an assessment of ability to meet these requirements by individual battery systems

Technical analysis of SW development requirements

SW development and testing

 Tests of possibilities of using free capacity and their evaluation

Specification of rules for the use of free battery capacity for ancillary services

LEEF Technologies is honored to have won the trust of the key local players to initiate and coordinate the Eflex project. The goal of the project fits into its current activities, focusing on the introduction of innovative technologies in the field of electromobility, energy storage and comprehensive energy savings.
