Zero Voltage Discharge Module ZVD Series is a specially designed module enabling total battery discharge (down to 0 V) required before recycling. It operates in a system with DV Power BLU units, providing total discharge of batteries with starting voltage up to 1350 V DC. BLU & ZVD system is universal, so it can be applied to fully discharge any battery type: Lead-acid, Ni-Cd, Li-based, etc.
The system improves the discharge process by discharging the battery in 2 steps:
-
Step 1: Efficient (up to 60 A) and controlled (current is constant down till 0 V is reached) discharge until the battery voltage drops to 0 V.
-
Step 2: ZVD short-circuits the battery to remove the remaining energy leading to total battery discharge.
BLU & ZVD system discharges the battery at a constant current (the current value is user-selectable prior to the test). The maximum discharge current for ZVD is 60 A.
