Introduction Introduction
Multiple battery chargers are sometimes employed in dc power systems to provide redundancy.
Two (2) or more chargers of the same voltage rating can be connected in parallel, each of them
capable of powering the connected dc load(s) and charging the battery. When two (2) or more
chargers operate in parallel, they normally will not share the load current equally. Since any
two (2) chargers will usually have slightly different connection paths, one of the chargers in a
system will typically have a slightly higher dc output voltage, and will therefore assume more
of the burden of providing the necessary load current.
ATevo's forced load sharing feature supports a single 'Primary' charger, and up to three (3)
'Secondary' chargers. The Primary charger communicates with Secondary chargers over a
serial connection. Each charger requires a Serial Communications Adapter (A13) set for RS-485,
wired to all other chargers, to create the forced load sharing communication network.
System Requirements System Requirements
All battery chargers must be ATevo Series. The ATevo forced load sharing feature will not
operate with legacy AT10.1 and AT30 Series battery chargers.
• All connected chargers must have the same voltage settings, have the same dc output
current rating, and have the same version of ATevo Main Control Board (A1) firmware.
• Each ATevo requires a 'FLS' Serial Communications Adapter (A13) to be installed in either
Port 2 or Port 3 of the Main Control Board (A1).
