4.4.6.1 Remote Status Monitoring
The following maintenance procedure requires a fully functional status monitoring system
capable of remotely measuring and recording the following data:
•
Battery Temperature
• Individual Battery Voltage
• Total Battery String Voltage
Please note: If status monitoring is not available, these checks need to be made
during the onsite visit and any batteries not meeting the minimum requirement must be
addressed at such time.
Procedure
1. If any individual battery voltage varies more than 0.5V above or below the average
for the string then a site visit is required.
Example V1 = 13V, V2 = 13V, V3=14V
Average voltage = 13.3V
If V3 greater than average by 0.5V, then a site visit is required.
2. If the PTS temperature is greater than 10 degrees C above the current regional
ambient temperature then a site visit is required.
3. Prioritize site visits based on highest PTS temperatures and battery voltages.
4. Visit the site periodically and remedy the problem by replacing the bad battery or
batteries and reset maintenance schedule.
