•
Apply the provided polarity labels as appropriate to the most positive and most
negative cell in the system.
•
Following IEEE 1187 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 1187 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 BATTERIES
Prior to starting the charge, make sure to check the tightness of all 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.
•
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
≥
2.10V, then the float charge commissioning process will be used as
defined in 7.0.1
o
2.08V, then a higher boost charge as defined in Section
o
If OCV is < 2.08V 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.
7.0.1 COMMISSIONING WITH FLOAT CHARGER VOLTAGE – 2.25 VPC
Place the batteries into service on float charge at 2.25 VPC. After a period of 24
hours the batteries should be in a fully charged condition.
