Storage battery. 1. Regular operation. Turn ON both solid state relays for charge and discharge control. Current flows in both directions. 2. Over-charge prevention. In order to prevent over charging, the solid state relay on the charge control side turns OFF. On the discharge side, current will flow because there is a diode.
Calculated by Eq. 1, when the insulation resistance r k of the line (positive or negative pole) drops to 3.8 kΩ, if the person happens to touch the other pole (negative or positive pole) of the line, the current flowing through the person is 50 mA (human body safety current for the DC system).
