Abstract
Disclosed is a bus short-circuit detection method and circuit, a storage medium and a processor. The method includes that: a weak electricity charge circuit is started in a case that a strong voltage detection circuit detects that a bus voltage of a unit is abnormal before the bus voltage is charged, wherein the weak electricity charge circuit is configured to charge the bus; charge current variation of the weak electricity charge circuit is detected; and a pre-charge circuit is started in a case that the charge current variation indicates that the bus is not in a short-circuited.
