Answer:

ESO (Energy Storage Optimizer) is Ferroamp's battery control unit in the EnergyHub system.

• The ESO manages and integrates batteries into the DC network. It serves as the bridge between the EnergyHub and the battery's BMS (Battery Management System).

• The ESO communicates with the EnergyHub via the DC network and with the BMS through the BMS's communication protocol using a communication cable.

• The ESO is also a bidirectional DC/DC converter that converts the voltage from the battery's voltage level to 760 V, which is the voltage in the DC network of the EnergyHub system. It also partially controls the charging and discharging power, where an ESO can convert a maximum of 6 kW or 9.5 A. The charging and discharging power is therefore also controlled by the battery modules' current and voltage levels, as well as by the BMS.

We constantly want to improve the content in the Knowledge Database and would appreciate it if you give feedback on our articles. Does all the information exist, is there anything that needs to be clarified or is there any information that is missing that would help installing or using the EnergyHub system in general? You can give us feedback by choosing if the article was helpful or not in the options below.
