摘要： A battery management system includes one or more fiber optic sensors configured to be disposed within an electrochemical battery. Each fiber optic sensor is capable of receiving input light and providing output light that varies based on the input light and an amount of free or dissolved gas present within the battery. A detector detects the output light and generates an electrical detector signal in response to the output light. Battery management circuitry determines the state of the battery based at least in part on the detector signal.

摘要： In a circuit (20) for use in controlling a battery-charging process and producing an output (S) which has one of two distinct levels (S1, S2), these levels are independently adjustable by adjusting variable resistors (R1, R2). Switching between the two levels is effected by transistors (T1, T2) in response to a varying input signal (X).The input signal (X) is derived from a hydrogen/oxygen recombinator (40, FIG. 4, not shown) with a thermoelectric transducer which produces an abrupt change in output when the battery is fully-charged. To ensure a gradual switch-over to a lower battery-charging rate, the output of the transducer is passed via an integrator (41) to the circuit (20). The switch means for one of the resistors (R2) may be omitted (FIG. 1 not shown).

摘要： The improved method of the present invention comprises charging a vented alkaline electrolyte-containing electrochemical cell employing an electrode pair selected from the group consisting of nickel-zinc, nickel-cadmium, silver-zinc and silver-cadmium and at least periodic measuring the charging efficiency of the cell by determining the rate of gas evolution from the cell. The charging of the cell is terminated when the charging efficiency substantially decreases, signifying the cell having reached an about full charge. The charging efficiency at that point normally substantially decreases to a value of about 0.5.+-.0.2. In the alkaline electrolyte-containing cells, the charging efficiency is determined according to the formula E=1-(15.8/I) v wherein E is the charging efficiency, I is the current in amperes and v is the gas generation rate in the cell in cc per second. The improved method prevents overcharging of the cell and accurately determines when an about full charge is reached. Accordingly, charging can be carried out without risk of damage to the cell and with the greatest efficiency.

摘要： A battery pressure transducer for producing a change in resistance with changes in pressure which includes a diaphragm having one side subject to pressure and the other side carrying a conductive layer. An annular resistive element is placed in slightly spaced relationship to the conductive layer and has a center contact and an outer peripheral contact. As pressure deflects the diaphragm, the conductive layer shunts part of the resistance and, thus, decreases the resistance between the contacts by an amount proportional to the pressure.
