Abstract
Abstract Monitoring apparatus for a series-connected battery of cells includes a lid equipped with biased contacts arranged so each contact contacts a different one of the cell connectors when in place. Wires from each contact run through a multiprong coupler to a contact of a double wafer switch, a plurality of switches being adapted each to connect pairs of wires for shorting out any selected cell. Each switch wafer has its contacts arranged to successively or selectively connect the connectors on either side of each cell across a voltmeter, the first wafer for about half the cells and the second wafer for the other cells for reading voltages for a pair of cells for each wafer switch position.

Claim 1
Independent Claim
337 words
Battery cell monitoring apparatus for batteries having a plurality of more than three electrochemical cells with exposed metal connectors between the series connected cells and between the terminal cells and battery terminals, comprising: a panel adapted to be secured to the top of the battery and having a plurality of downwardly biased contacts thereon, the biased contacts being reciprocally secured to the panel and arranged and spaced in a predetermined design for each contact engaging with a different connector when the panel is secured, all connectors being so engaged, a selector switch having at least one fixed wafer, a plurality of angularly spaced contacts on the wafer, means electrically connecting each biased contact to a pair of wafer contacts, the wafer contacts connected to the connectors on either side of each cell being diametrically oppositely located on the wafer, switch wiper arm means rotatably mounted adjacent each wafer, the arm means having a first and a second contact at diametrically opposite ends of the arm adapted to simultaneously contact diametrically opposite wafer contacts, a voltmeter associated with each wiper arm means, the first and second contacts being substantially continuously electrically connected across the voltmeter, means for manually rotating the wiper arm means for successively and selectively connecting the voltmeter for reading across each cell, indexing means associated with the rotating means for indicating the wafer contacts being contacted by the first and second contacts, and a normally open shorting switch connected between each pair of electrically connecting means connected to adjacent connectors in the cell series for selectively shorting out any selected cell, the shorting switches being secured on the panel top, the electrically connecting means between the shorting switches and the wafer contaCts being secured in a single cable having a single separable coupling device therein, the coupling device having separate coupling means for each wire in the cable, whereby the coupling means may all be quickly uncoupled and the selector switch and voltmeter removed leaving the panel on the battery with the shorting switches closed.
