Abstract

Managing a battery including measuring, in response to a first charging current and over a first time period, a first amperage and a first voltage of the cell at predetermined intervals; measuring, in response to a second charging current and over a second time period, a second amperage and a second voltage of the cell at the predetermined intervals; determining that the first amperage of the cell was maintained greater than a first threshold amount of time within the first time period, and in response, qualifying the first amperage and the first voltage as stable; determining that the second amperage of the cell was maintained greater than a second threshold amount of time within the second time period, and in response, qualifying the second amperage and the second voltage as stable; and in response to the qualifying, calculating a DCIR of the cell based on the voltages and the amperage.
