Following a power outage, various power engineering objects such as power plants should operate on battery backup systems. It is necessary that these batteries are properly charged in order to compensate for their energy loss and keep their voltage within the predefined limits. DV Power’s chargers are portable and universal battery charging solutions. They are primarily intended for charging Lead-Acid, Ni-Cd, and Li-ion batteries from 1 V DC to 300 V DC level. They are intended to support the main charger in order to charge the battery much faster or to quickly recharge a battery following a discharge test.
Several methods for charging batteries have been developed to meet the “rules for proper charging”. Some of these methods are known as the constant-current method, constant voltage method, modified constant-voltage method, float charging method, and trickle charging method. Charging methods largely depend on the type of battery.
DV Power’s chargers can operate in either of two charging modes:
- IU – constant current + constant voltage
- UU – constant voltage + constant voltage, with current limit
and all three major battery chemistries (Lead-Acid, Nickel-Based, and Li-ion) can be charged using these two modes.
Charging modes provide a safe regulation of the charging procedure and achieve fast recharge and a low risk of overcharging. A variety of implemented protections, such as thermal, overcurrent, undervoltage, and overvoltage, assure the charging process is safe for the battery and the charger itself.
