| Zusammenfassung: | The invention discloses power battery electric leakage resistance and electric leakage position detection methods and corresponding electronic equipment. The power battery electric leakage resistancedetection method includes acquiring voltages of two ends of a second resistor and a third resistor when a first switch is turned on and a second switch is turned on to obtain a first voltage value Vpand a second voltage value Vn respectively, acquiring voltages of two ends of the second resistor when the first switch is turned on and the second switch is turned off to obtain a third voltage valueVp1, acquiring voltages of two ends of the third resistor when the first switch is turned off and the second switch is turned on to obtain a fourth voltage value Vn1, calculating a unilateral power battery negative electrode insulation resistance value Rn1, a bilateral power battery negative electrode insulation resistance value Rn2, a bilateral power battery positive electrode insulation resistance value Rp1 and a bilater |
