Abstract: An insulation detection method includes: a first and second equivalent resistances are calculated; the less one of the first and second equivalent resistances is taken as a first insulation resistance, which is an insulation resistance of the high voltage circuit on the side where the battery pack locates relative to the reference potential terminal; when the first insulation resistance is normal, the switch unit is closed, and a second insulation resistance is calculated according to the first and second equivalent resistances, voltages of a first and second sampling point when the switch unit is closed; the second insulation resistance is an insulation resistance of the high voltage circuit on the side where the load locates relative to the reference potential terminal; the insulation state of the high voltage circuit on the side where the load locates is determined according to the second insulation resistance.
