Following IEEE 484 guidelines BAE recommends measuring and recording
connection resistance readings to verify connection integrity and to provide a
baseline of each connection. Recommendations for how to measure these readings
is contained in the IEEE 484 guideline document, but all connection resistance
readings must be measured directly off the battery posts.
o
Measure and record inter-cell connection resistances. This value verifies the
adequacy of initial installation and provides a reference for future maintenance
testing.
o
Review the records of each connection-resistance measurement, separated by
connection type (i.e., inter-cell, inter-tier, inter-rack). Compute a separate
average for each connection type. The calculated average must be within BAE
specification for the connection type.
o
Identify connections if the measured resistance is the greater of 1.1 x the average
resistance of each connection type, or the average resistance for the connection
type plus 5 micro-ohms. Unmake, clean, and remake the identified connections
and re-measure the identified connection resistances.
•
Ensure the proper warning and safety signs are present and installed properly for the
battery room.
•
Additionally please ensure the proper Personal Protection Equipment (PPE), spill
containment or cleanup kit and eyewash are present within the battery room as
required per the local or national codes. Please contact your local BAE
representative if any of these items are needed for your installation.
7.0 COMMISSIONING - SUPPLIED WET AND CHARGED
Prior to starting the charge, make sure to check the tightness of the terminal connections
and verify the proper polarity on each cell. Remember, the charger positive connection
must be connected to the battery positive terminal. DO NOT APPLY CHARGE TO THE
BATTERIES YET.
Before applying any charge to the batteries the following steps must be completed.
•
If not already installed, install all flame arrestor vents onto cells. The arrestor vents
will be a fixed or funnel flip top style. Do not charge cells with shipping caps
installed.
•
Measure and record the Open Circuit Voltage (OCV) of each cell and ambient
temperature. The extent the batteries have discharged during storage determines
the commissioning process for the cells.
o
If OCV is
≥
2.075V, then the float charge commissioning process will be used as
defined in 7.0.1
o
If OCV is < 2.075V but
≥
2.065V, then a higher boost charge as defined in 7.0.2
will be required
o
If OCV is < 2.065V contact BAE USA or your local representative.
Once the pre-commissioning charge measurements are completed, the commissioning
charge can begin. Use the process as determined by the OCV measurements above.
