Description
technical field [0001] The invention relates to the field of charger detection, in particular to a detection system for the output characteristics of a lead-acid battery charger. [0002] systems and their detection methods. Background technique [0003] At present, the detection of the output characteristics of lead-acid battery chargers is basically done manually. It is necessary to sequentially test the output characteristic parameters of the charger such as no-load voltage, constant current charging current value, constant voltage charging voltage value, and float charging voltage value. . Due to the long charging time of the battery, in order to reduce the detection time, an external load resistor is generally used to simulate the output voltage and current. Manual testing generally first tests the output voltage of the charger when the battery is not connected, that is, the no-load voltage; then connect a certain load resistance at the output end to make the output v...
