摘要

Coupling to stifle the open drum pressure of cxrcuxt, coupling to pump the state of battery load and process to control it an equipment to estimate an OCV of a battery includes a voltage measurement unit to measure an output voltage; a Age of temperature measurement to measure a battery temperature; a data storage unit to periodically receive battery output voltage and temperature data from the measurement units and store data in a memory;An OCV variation estimation unit to calculate an OCV variation of a variant pattern of battery output voltages measured in the past and present, stored in memory, by applying a mathematical model that defines a correlation between the pattern of variation And the variation of OCV, and estimate an OCV at a current stage by reflecting a correction factor that corresponds to the battery temperature in the calculated OCV variation; and an OCV estimation unit to estimate an OCV at the current stage by reflecting the calculated OCV variation in the estimated OCv in U My last phase.
