초록 ▼

Apparatus for indicating the charge condition of a secondary cell, comprising an integrating device which progressively sums the ampere-hours drawn from the cell, and a computer which is programmed to provide a voltage output whose magnitude indicates the total number of ampere-hours available, from the battery at the particular discharge current and temperature. A comparator subtracts from this a voltage derived in accordance with the output of the integrating device. The comparator output thus indicates the remaining ampere-hours available to be drawn from the cell at the prevailing conditions of discharge current and temperature. There may be provided a further computer which is programmed in accordance with the variation in minimum ampere-hour requirement of the cell to ensure that a particular load, e.g. a starting motor, can be successfully operated at various temperatures. This comparator can be arranged so as to provide an indication as to whether or not the charge condition of the cell is sufficient to operate this load.

대표청구항 ▼

An apparatus for measuring the charge condition of a secondary cell, comprising, in combination: electric sensing means coupled to said cell and operable for producing a first signal substantially proportional to current flowing in or out of said cell; first conversion means coupled to said first signal and operable for producing a second signal substantially proportional to the consumed ampere-hours of said cell measured from a predetermined full charge condition and compensating for any subsequent charging; a temperature sensor operable for producing a third signal as a function of the temperature near said cell; second conversion means coupled to said first and third signals and operable for producing a fourth signal substantially proportional to the estimated available ampere-hours of said cell with respect to said full charge condition as a function of said first signal, and said third signal; and a comparator coupled to said second and fourth signals and operable for producing a fifth signal representing the relative amplitudes of said second and fourth signals, whereby said fifth signal represents a measure of the charge condition of said cell.
