operating conditions and assure to know and understand the used charging technology.
(Also note the information in chapter 7 "Operation".)
Make sure that only qualified and protected personnel have access to the battery system
and that they are familiar with the contents of these operating and service instructions,
and in particular with the safe handling instructions of batteries described in chapter 2
"Safety". A battery is
always live
, even when it is disconnected from the charger or the
external circuit. Pay attention during inspection and repairs on live parts and avoid open
flames, static discharges, sparks and short circuits with clothing, jewellery, watches and
tools. Ensure insulated tools are used.
8.1
Inspection
Periodically check and verify that the battery system functioning correctly.
Preventive maintenance procedure See Detail Interval
Constant voltage of charging
at the terminals of the battery
At commissioning,
later every 4 to 12 months
Cleaning and visual inspection
Every 12 months
8.1.1 Checking of charge and cell voltage
List of tools for this inspection action:
Designation
Comments
Digital voltmeter
with thin measuring tips
(Measuring hole connector cover
2mm)
DC voltage measurement
with display precision 0.001 V at cell voltage
DC-Clamp Meter
Cable diameter approx. 15mm
for measured values <1A and <60 A
Temperature Meter
possibly with an external sensor
Tool for accessing
According to documents of the corresponding
battery box
Check and
adjust, at least once a year, the constant charge voltage
in accordance with the instructions of the charger manufacturer. At the
same time, measure and record the individual cell voltages.
The following measurements should be regularly carried out and recorded. Select the
measurement interval corresponding to the functional importance of the battery system
(e.g. its relevance to the safety of persons). For projects with Battery Monitoring System
BMS this function may be partly carried out automatically and a realisation of these
measurements is only necessary in case of an error message.
Check the setting of the voltage controller of the charger every 6 to 12 months.
Integrate this test in an inspection modus with an appropriate interval.
