BATTERY CHECK DEVICE

摘要

PURPOSE: A battery check device is provided to minimize battery consumption and electric impulse generated in checking residual capacity of the battery. CONSTITUTION: A battery check device comprises a terminal voltage detection unit(21), a sampling/holding unit(22) and an output unit. The detection unit(21) detects the terminal voltage of the battery by variably structuring respective corresponding circuit in order to measure the voltage in loading or unloading. The sampling/holding unit(22) measures the analog values of the voltage detected by the detection unit. The output unit receives the output signals of the sampling/holding unit(22) to convert them into readable format.
