Irizar e-mobility, EMT Madrid and Iberdrola have announced a new collaborative project that aims to reuse electric batteries at the EMT operations centre in Fuencarral.
A new stationary type static storage system for electrical energy has been installed in those facilities in order to refurbish batteries that have reached the end of their first life.
Irizar e-mobility has designed, manufactured and used its own batteries for over seven years, and has stated that the reuse and second life of the batteries has always been a top research priority.
With batteries undergoing daily recharging cycles, their storage capacity is gradually diminished, leading to the need to replace the batteries depending on the degree of wear. This new project will see older batteries used to back up the charging of EMT buses, with the goal being that they will be used as an element integrated into the buses’ smartcharging system in order to to reduce both power spikes and demand during usual battery charging times, as well as optimise the charging process.
The container for the batteries is charged during off-peak times to optimise energy prices and increase the use of green energy. It has a maximum storage power and energy of 1 MWh and 500 kW for charging and discharging respectively.
With fifteen racks of batteries in place from three separate Irizar e-mobility vehicles, the container can also be managed through the EMT smartcharging system, which is used to charge the municipal company’s fleet of electric buses every day at the Fuencarral operations centre.
The project has been developed in the framework of the PERTE VEC (CAPITAL) programme.
