Abstract
The present disclosure relates to a power storage control device, a power storage control device control method, a program and a power storage system which can enhance reliability more. The power storage control device has: an AC/DC converter which converts power supplied from a power system; a DC/DC converter which converts power outputted from a storage battery which stores power; and a control unit which is driven by the power outputted from the AC/DC converter and the power outputted from the DC/DC converter, and controls charging and discharging of the storage battery. Further, in the power storage control device, a voltage value of the power outputted from the AC/DC converter is set higher than a voltage value of the power outputted from the DC/DC converter. The present technology is applicable to, for example, a power storage system.
