Lee Sheng-electronics factory Teaches you electric car charger Troubleshooting maintenance solutions for common problems: no DC voltage output or voltage output is unstable - 1, first of all, with a multimeter to measure various components of the high-frequency pulse transformer damage, exclude high frequency rectifier diode breakdown, the load short-circuit; 2, and then measure the DC voltage at each output, battery charger wholesale, if the time output is still zero, you can be sure that the power control circuit failed; 3, and finally with multimeter static measurement of high-frequency filter circuit and low-voltage rectifier diode filter capacitor is damaged, if the above components are damaged, replace the good new components, the general failure can be ruled out. Lee Sheng Electronics Factory teach you proper electric car charging methods: 1, always remove the battery cover of the dust, dirt, keep the battery dry, clean, Yongkang battery charger to prevent the battery self-discharge. 2, must not allow the battery a long period of low battery condition, and to charge the battery every night to develop good habits. Long-term need, battery charger Which is good, it should be fully charged, place a cool, dry place and recharge regularly (usually 10 days).
