摘要： Provided are a charging and discharging device, a charge/discharge control method, and a computer program capable of causing a higher-level device to implement appropriate charge/discharge control. This charging and discharging device has a connector for a vehicle-mounted power cable connected to a vehicle-mounted storage battery provided in a vehicle, and controls charging and discharging of the vehicle-mounted storage battery. The charging and discharging device is provided with: a storage unit in which are stored, in advance, at least one of the minimum value and the maximum value of each of a charging power value, a charging current value, a discharging power value, and a discharging current value; a determining unit for determining, on the basis of data exchanged with a vehicle-mounted control device for controlling charging and discharging of the vehicle-mounted storage battery on the vehicle side, the values of at least one of the minimum value and the maximum value of each of the charging power value, the charging current value, the discharging power value, and the discharging current value during charging or discharging of the vehicle-mounted storage battery; and a notifying unit for notifying a higher-level control device of any of the values determined by the determining unit and values read from the storage unit.

摘要： Provided are a charge/discharge device, a charge/discharge control method, and a computer program that exhibit high responsiveness while following a prescribed sequence that corresponds to a charge/discharge procedure. This charge/discharge device has a connector to an onboard power line connected to a storage battery provided in a vehicle, the charge/discharge device controlling charging and discharging in the storage battery, wherein the charge/discharge device comprises: a communication unit that establishes a communication connection with an onboard control device that switches on and off a vehicle-side relay interposed in the onboard power line; a communication control unit that exchanges messages with the onboard control device through the communication unit on the basis of a prescribed sequence; and a connection-standby-state-maintaining unit that maintains a connection standby state in which the vehicle-side relay remains on while the storage battery is not being charged or discharged after the vehicle-side relay has been switched on on the basis of the prescribed sequence.
