摘要： A management apparatus for an energy storage device, wherein after the start of counting an elapsed time since a current of the energy storage device became equal to or smaller than a first threshold, when a predetermined condition in which the voltage of the energy storage device is possibly not stable is satisfied at a time point where the count reaches a stabilization time (predetermined value), the count of the elapsed time is changed.

摘要： A management apparatus for an energy storage device, which performs current measurement processing for measuring a current of the energy storage device by using a measuring resistor having one side connected to the energy storage device and the other side connected to an external terminal, temperature measurement processing for measuring at least one of a temperature of the energy storage device and a temperature of the external terminal, and correction processing for correcting, when there is a temperature difference between the temperature of the energy storage device and the temperature of the external terminal, a measurement error caused by the temperature difference for a measured current value measured by the current measurement processing, or guarantee processing for guaranteeing a function to be performed in accordance with a measured current value measured by the current measurement processing.
