Troubleshooting
Note
Follow the safety instructions, see
2 Safety instructions on page 9.
10.1.
Insufficient capacity
If the capacity of the battery system is too low, proceed as follows:
Cause
Remedy
Loose or oxidised terminal(s)
Check all connector(s), replace the
connector(s) if required (use new spring
washer(s))
Temperature sensor has a defect.
That causes incorrect charge
parameters.
Check the temperature sensor if available
10.2.
Insufficient insulation resistance
When commissioning a new battery, the insul
ation resistance must be > 1 MΩ. It decreases
with the operating time (due to aerosols from the batteries, condensation, dust) and may not
fall below the following values depending on the nominal battery voltage:
Battery nominal
voltage
Norm
Insulation Resistance (minimum value)
below 100 V
DIN VDE 0119-206-4
10
kΩ
between 100 V
and 120 V
DIN EN IEC 62485-2
100 Ω per Volt nominal voltage
Above 120 V,
i.e. from 100
cells
DIN EN 62485-3 09/2015
Number of cells x 1.2 V nominal
voltage x 500
Ω /V
If these minimum values are not reached, a possibly existing insulation monitor of the
vehicle may response, an undesired increased discharge and loss of battery performance
may occur.
If the insulation resistance is too low, leakage currents can reduce the available capacity.
This can also cause differences in voltage between the cells. Regular cleaning prevents
these leakage currents.
Cause
Remedy
Contamination
Cleaning
Cells / Blocks is/are leaking
Remedy the problem or replace the cell if
necessary
