Abstract
Provided is a comprehensive testing stand for a charger used for an electric bicycle. Various independent testing units used for detecting performance of the charger are combined by the testing stand to be a whole body. The testing stand comprises a power frequency voltage regulator, an AC voltmeter, a power meter, a digital thermometer, a voltage withstand tester, a DC voltmeter, a DC ammeter, a storage battery, an electric rheostat, a short circuit testing unit, a reversal connection testing unit, etc. Through conversion of a control unit, the testing stand enables a charger to be tested to be respectively connected with the electric rheostat and the storage battery, thereby detecting a current limiting charging value, a constant voltage charging value, a floating charging voltage value and a fall-back current value of the charger. Temperature rises of the charger are detected by the digital thermometer. Leakage currents and electrical intensity of the charger are detected by the voltage withstand tester. Through the power frequency voltage regulator, input voltages are changed and power supply adaptation capabilities of the charger are detected. Power of the charger is detected by the power meter. Protection functions of the charger are detected by the short circuit testing unit and the reversal connection testing unit.
