초록 ▼

There is disclosed an instrument for the continuous monitoring of emergency stand-by batteries during operation of the batteries. The invention monitors the emergency batteries during all discharge operations and records the usage and conditions of the batteries as well as alerts the operators when the discharge voltage of the batteries falls below the minimum required for the particular application. The instrument includes voltage, current and temperature sensors which generate signals that are applied through gain amplifiers to an analog to digital converter and then to a central processing unit. The central processing unit receives a reference voltage and has an independent emergency power supply. The central processing unit outputs signals to a liquid crystal display as well as to a printer and receives commands from a key pad. The central processor unit is supplied with a software operating program which is recorded on a ROM and has system RAM for non-volatile storage and a clock. The instrument is programed to record battery usage in total accumulated numbers of battery discharges of greater than one or more preset durations, total accumulated time (duration) of battery discharges, total accumulated battery discharge power (KW Hours) as well as recording charging information such as the battery float voltage, the ambient temperature of the batteries, and the recharge current and voltage during the initial recharge periods. This information is printed every 24 hours and after every battery discharge.

대표청구항 ▼

A battery monitoring system to detect and record conditions of a rechargeable battery utilized in a stand-by mode, in an emergency power discharging mode and in a charging mode, which comprises: a) detection means including battery voltage detection means; battery current detection means; clock means; and ambient battery temperature detection means; b) computer means receiving detection signals from each of said detection means during said stand-by, charging and discharging modes, and operative to provide output signals of: (1) instantaneous battery voltage and current; (2) date and time of said instantaneous signals of battery voltage and current; and (3) battery temperature; c) summation means operatively associated with said computer means to prepare and provide output total use signals for each of the following: (4) total accumulated number of discharge uses; (5) total accumulated number of discharge uses lasting over a first predetermined time period; (6) total of lapsed minutes of discharge uses; and (7) total accumulated battery discharge power; d) incipient battery failure detection means including: (8) storage means to receive a preset end voltage selected by the user and representing the minimal permissible voltage for useful operation; (9) comparator means receiving the detected instantaneous battery voltage during discharge; and (10) alarm means to indicate a deteriorated battery condition when said instantaneous battery voltage decreases below said preset end voltage; and e) recording means to record said detection signals and said total use signals.
