Battery replacement synchronous locking method and battery replacement synchronous unlocking method

The invention discloses a battery replacement synchronous locking method and a battery replacement synchronous unlocking method, during battery replacement locking, a locking and unlocking mechanism of a battery replacement robot drives a locking rotation assembly of a battery to rotate along a locking rotation direction, whether all the locking rotation assemblies of the battery reach preset positions or not is judged, if yes, locking is continued, and if not, locking is stopped; if yes, all the locking rotating assemblies of the battery are unlocked firstly, then locking and battery replacing unlocking are conducted, when locking and battery replacing unlocking are conducted, a locking and unlocking mechanism of the battery replacing robot drives the locking rotating assemblies of the battery to rotate in the unlocking rotating direction, whether all the locking rotating assemblies of the battery reach the preset positions or not is judged, if yes, unlocking continues, and if not, unlocking is conducted.
