ČEZ & ČEPS test chargers with battery, photovoltaics

In collaboration with ČEPS, ČEZ is testing a battery in Vestec near Prague, which should help stabilise the Czech distribution system in the future.

Three ČEZ charging points for electric vehicles are accompanied by a roof-mounted photovoltaic system with a battery. Thanks to its capacity of 274 kWh, this system can charge the batteries of seven midsize e-cars if there is an electricity blackout. The system is being used to test a partial island operation of the charging points for use at places with a low or restricted network output. In addition, ČEPS is performing tests to determine whether the batteries will prove themselves in the provision of auxiliary services. The first results hint that there is nothing to prevent them from assuming the role of virtual batteries.
