摘要： The battery of this invention is equipped with an electrode for detecting the lowering of the level of the electrolyte. A circuit for detecting the ''''on and off'''' of the electric current is attached to the battery and actuated an alarming device in the circuit when the level of the electrolyte is lowered below the predetermined level. Then electric power for this circuit is obtained from the battery itself through said electrode. According to this invention, the lowering of the electrolyte level in the battery can be automatically alarmed.

摘要： There is disclosed a monitor for monitoring the state of charge of a battery having an internal charge transfer medium. A monitor includes detecting means arranged to be disposed beneath the surface of the charge transfer medium and arranged for sensing the specific gravity of a fluid medium, enclosure means for enclosing the detecting means, and a fluid medium within the enclosure means. The fluid medium exhibits specific gravities related to the degree of electric charge therein and the enclosure means is formed at least partly from a non-permeable electric charge transmissible material to enable the fluid medium to assume the electric charge of the charge transfer medium while substantially separating the fluid medium therefrom. The monitor further includes indicating means responsive to the detecting means for indicating the specific gravity of the fluid medium and thus the state of charge of the battery.

摘要： Intermittent operation of a pump feeding fuel to the battery is controlled by circuits which produce pump operation cycles at intervals determined by energy used in the load circuit as well as additional cycles if the voltage falls below a fixed limit. Compensation for the drop in concentration of the fuel as the result of recirculation of partly spent fuel is provided by lengthening the pump operation cycles or making them more frequent with respect to power energy consumption in the load, or both.

摘要： A testing device for determining the cranking ability of a storage battery under simulated low temperature conditions is described. The device imposes an auxiliary load on the battery during an engine cranking operation at normal temperature. The auxiliary load is approximately equivalent to the combined effect on the battery and engine of low temperature. Battery condition is determined by its ability to crank motor with the additional load.

摘要： The invention concerns a circuit for spot measuring the distinctive voltage-current characteristic of a solar battery subjected to a given degree of illumination, in which the charge circuit of the solar battery being tested comprises, in series, a fixed resistance whose terminal voltage is a measure of the strength delivered by the solar battery, and a voltage source whose instantaneous value depends on that of the battery''s terminal voltage and whose variations in value around a central value are opposite to and much greater than the terminal voltage variations of the solar battery around a predetermined value in conformity with the testing conditions.
