A server (management apparatus) includes: a communication unit (first acquisition unit) that acquires a request regarding adjustment of electric power supply-and-demand in a power grid; and a processor (controller) that performs, based on the request, control to notify, a user of an electrically powered vehicle, of a replacement cost required for battery replacement at a battery station (battery replacement apparatus). When charging with electric power of the power grid is requested and a battery (first battery) of the electrically powered vehicle has an SOC lower than the SOC of a battery (second battery) having a maximum SOC to be used for charging, among a plurality of batteries (second batteries), the processor performs control to notify the user of the replacement cost lower than a normal replacement cost.
