摘要： A master controller of a battery charge and discharge control apparatus is a device performing charge and discharge control on a group of a predetermined number of battery arrays, the battery arrays being connected together in parallel. The master controller acquires an entire charge or discharge instruction intended for the entire battery array group, starts charging or discharging each of the battery arrays at a uniform charge or discharge power value, acquires a charge or discharge status of each of the battery arrays after the beginning of the charge or discharge and compares the charge or discharge status with a predetermined charge or discharge set value for the entire battery array group, and changes the charge or discharge power value of each of the battery arrays based on a result of the comparison.

摘要： Provided is a power management system capable of controlling charge and discharge of storage batteries according to power requirement of load even when handling electric power of large scale. A system controller receives load-related information data including the power requirement of load and storage battery-related information data including a state of a storage battery assembly including multiple storage batteries and creates an overall charge-discharge control instruction for the entire power management system based on the load-related information data and the storage battery-related information data. A hierarchical charge-discharge control apparatus receives the overall charge-discharge control instruction from the system controller and performs charge-discharge control of the multiple storage batteries, classified into hierarchical levels, on a hierarchical level basis.

摘要： An electric power management system is provided which executes charge and discharge control by detecting a state of charge of a storage battery pack with a high precision and controls charging and discharging of a storage battery system comprising a plurality of storage battery units. A total storage battery unit manager calculates an SOC of all storage battery packs in the storage battery system, and controls charging and discharging based on the calculated SOC. When a wait state, where the storage battery system is not charging or discharging, continues for a predetermined period, the SOC is calculated using a correlation relationship between an electromotive force and the SOC, to remove the influence of hysteresis.
