The battery management system of the HXN6 hybrid diesel locomotive was researched. From the plan design, practical application and the special circumstances of the SOC (remaining battery power) algorithm, a dynamic SOC calibration strategy based on charge stating was proposed. Under the condition of inaccurate acquisition accuracy in wide current range, the problem of too large estimation bias of SOC was solved, which had good engineering application prospect.
