とを備えてなる蓄電池最低電圧記録装置。[Claims for Utility Model Registration] A/D conversion means that converts an analog DC voltage output from a storage battery into a digital value and outputs it as a real-time digital storage battery voltage; and the real-time digital storage battery voltage when receiving a latch command. latch means for taking in and holding it as a latch voltage; comparison means for comparing the real-time digital storage battery voltage and the latch voltage and issuing the latch command when the real-time digital storage battery voltage is smaller than the latch voltage; charging/discharging state detection means for generating a charging start signal when the charging state switches from a discharging state to a charging state; and means for storing the latch voltage at the time of receiving the charging start signal as the lowest voltage of the discharging period. Storage battery minimum voltage recording device.
