First Claim
Patent Images
1. An apparatus for maintaining the charging of valve regulated lead-acid (VRLA) batteries wherein said VRLA batteries operate exclusively at temperatures less than about 130°
- F. comprising;
a. at least one bulk charger capable of charging a multiplicity of VRLA batteries;
b. at least one SCADA computer capable of controlling the at least one bulk charger;
c. at least one Battery Management System Node circuit board capable of independently charging at least one associated battery; and
d. an optical interface network connecting the at least one Battery Management System Node circuit board with the at least one SCADA computerwherein said apparatus eliminates the outgassing of water and electrolyte from the batteries when charging the batteries, andwherein each VRLA battery will be recharged in current mode without voltage limits on the charger power supply.

Abstract
The present invention deals generally with an apparatus and method for charging valve regulated lead-acid (VRLA) batteries (modules) in series and series-parallel arrangements. More specifically, the present invention relates to an apparatus and method of individually, and very precisely, charging valve regulated lead-acid batteries in series and series-parallel arrangements so as to limit the water and electrolyte outgassing conventional bulk charging methods produce.
