Lead-acid battery state measuring device has microcontroller that receives output signals of current sensor and temperature sensor to determine current and temperature of lead-acid battery and voltage setting of lead-acid battery
The device includes a microcontroller that receives the output signals of a current sensor and a temperature sensor to determine the current and temperature of a lead-acid battery and voltage setting of the lead-acid battery. The microcontroller regulates the operation of a current source by means of a digital-to-analog converter (DAC). The current sensor measures the current passing through lead-acid battery. The current sensor operates based on reference impedance. A capacitor and a relay are provided for auto device calibration. An LCD screen displays the measurement results. An ES-232 interface is provided to connect the device to a computer.
