| description | The invention provides a battery internal resistance component measuring method. The battery internal resistance component measuring method comprises the steps of updating battery capacity data; charging or discharging the battery for a short time, and standing for a certain time; recording instantaneous voltage jump delta U1 at the initial standing moment and slowly changing voltage delta U2 so as to obtain direct-current internal resistance of the battery: R1 = [delta] U1/[delta] I, R2 = [delta] U2/[delta] I, wherein R1 comprises ohmic internal resistance and interface charge transfer internal resistance, R2 represents concentration polarization internal resistance of the battery under the condition, and [delta] I is charging or discharging current; and carrying out an alternating current internal resistance test on the battery after standing to obtain a resistance value R0 representing the ohmic internal resistance of the battery so as to obtain the electrochemical polarization internal resistance Rct = R1 |
