Floating Charger

Floating Charger:

·         Floating Charger is used to maintain the battery voltage. It charges the battery as similar rate of battery discharge. Example now battery is draining two ampere means the charger supplies 2 amperes of current. if the battery voltage is full then the battery stops supplying current. Like that floating charger works. At that same time Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery

·         Charging rate is Slow

·         Mainly used to avoid over charging of battery.

·         Battery chargers may stop when the battery is full. A float charger senses when a battery voltage is at the appropriate float level and temporarily ceases charging; it maintains the charge current at zero or a very minimal level until it senses that the battery output voltage has fallen, and then resumes charging

·         The output voltage of the float charging is low as compared with boosting charging.

·         A float charger may be kept connected indefinitely without damaging the battery.

·         It needs soft start arrangement to avoid high initial Float current resulting from restoration of main A.C. supply.

·         It will have separate transformer, rectifier and controls etc.
