Abstract: Provided are a direct current resistance (DCR) detection method for batteries, a system, a device, and a storage medium. Multiple discharging current pulses are applied during the constant current charging process of a battery to form a negative pulse charging mode. The discharging current can be added during the charging process to quickly remove the polarization effect of a battery cell generated during the charging process, thereby improving the charging acceptance capacity of the battery cell, shortening the charging time and increasing the charging efficiency. At the same time, a first battery voltage is obtained during the discharging current pulse time period, and a second battery voltage is obtained during the constant current charging time period after the discharging current pulse, thereby obtaining a DCR value of the battery during actual charging and use. The DCR of the battery cell can be detected simultaneously in the negative pulse charging mode.
