摘要

A battery voltage drop alarm circuit comprises a battery voltage drop detecting circuit, an alarm circuit, and an alarm cut off circuit. The battery voltage drop detecting circuit outputs an alarm instruction signal to the alarm circuit when the battery voltage drops to less than a predetermined value, then the alarm circuit generates an alarm sound. The alarm cut off circuit generates an alarm operation cut off signal to the alarm circuit to cut off the alarm operation thereof when the battery forklift performs the auxiliary work.
