20110208360 | ON DEMAND ELEVATOR LOAD SHEDDING - Upon request from a power utility to reduce the electrical demand of a building, an elevator system is automatically disconnected from power being delivered by the power utility (or remains connected but receives limited power from the power utility), and a secondary power storage device is connected to the power bus of the elevator system. The secondary power storage device provides power to the elevator system during a period in which the request to reduce electrical load of the building is in effect. When the request end, the elevator system is automatically reconnected to the power delivered by the power utility and can potentially work in a hybrid mode. | 08-25-2011 |
20110226559 | BATTERY STATE-OF-CHARGE CALIBRATION - Calibration of the state-of-charge (SOC) of a battery-based energy storage system used with a regenerative drive uses an SOC-open circuit voltage (V?oc#191) correlation. The battery is partially charged or discharged to assure operation defined by V?oc#191 following a known V?oc#191-SOC profile, such as a charge or discharge boundary curve. The partial charging/discharging may be synchronized with a traffic profile of an elevator system driven by the regenerative drive. A V?oc#191 measurement is made, and by enhancing the relaxation dynamics of V?oc#191 through regulating battery usage with a reference to traffic profile, a V?oc#191 is estimated more reliably. Using the estimate V?oc#191 and the known V?oc#191-SOC profile, state-of-charge of the battery is determined. | 09-22-2011 |
