Abstract

Discharge circuit and voltage testing circuit are setup at an input end of power source. The output end of the voltage testing circuit is connected to the control end of the timing circuit. Output end of the timing circuit is connected to the display circuit. The voltage testing circuit includes referenced voltage regulator circuit, sampling circuit for source voltage, and voltage comparator. Output ends of referenced voltage regulator circuit and sampling circuit for source voltage are connected to two input ends of voltage comparator respectively. Voltmeter is connected between two input ends. After accumulator is discharged in short time, voltage of accumulator is dropped to voltage smaller than voltage references, and then the voltage comparator is inverted, the timing circuit is locked, display circuit displays capacity of accumulator in simulation. Advantages are: local test and quick testing.

Description

technical field [0001] The invention relates to an electronic instrument, especially an improvement to a storage battery capacity detector. Background technique [0002] During the use of the battery, due to the consumption of water in the electrolyte and the decrease in the activity of the plate material, the capacity will decrease. The current instrument used to detect battery capacity is composed of a discharge circuit, a voltage detection circuit, a timing circuit, and a display circuit. A discharge circuit and a voltage detection circuit are provided on the power input terminal, and the output terminal of the voltage detection circuit is connected to the control terminal of the timing circuit. Connection, the output terminal of the timing circuit is connected with the display circuit. When the battery is fully charged, discharge it with a fixed current until the voltage drops to the lower limit of the battery voltage, calculate the time of this process, and measure the...
