Remedy
Incorrect assignment
of the signal module
Missing terminating resistor
No CAN communica-
tion to the battery pack
Defective CAN topology
in the higher-level system

Outdated Error
Pack or cell voltage too high. Disconnect
any system causing the problem. Ambient
temperature between 5 and 25°C is
advisable. Wait until the battery has
dropped in voltage and connect to a load
in order to discharge the battery.

Outdated Error
Pack or cell voltage too low. Disconnect
any system causing the problem. Ambient
temperature between 20 and 30°C is
advisable. Wait until the battery has
recovered in voltage and connect to a
charger in order to charge the battery.

Outdated Error
One of the temperature sensors has
exceeded the maximum temperature.
Disconnect any system causing the
problem. Create an ambient tempera-
ture between 0 and 20°C. Observe if the
battery temperature continues to rise for
more than 30 min (or above 60°C); if so
there is danger of re! If still possible
safely, move the battery into a space
where a re would not cause harm. Else
evacuate the area.

Board Param
Outdated Error
One of the temperature sensors has
dropped below the minimum tempera-
ture. Disconnect any system causing the
problem. Create an ambient tempera-
ture between 20 and 30°C and wait until
the battery becomes warmer (could take
hours/over night). Never attempt to
charge a battery in an under-temperature
situation!

Current
Outdated Error
Too much current was drawn over too long
a time. Reduce the load connected to
the battery. Program a derating strategy
into the user system, that observes the
"State of Power". Within the continuous
load regime, the SOP is 100%. When peak
loads are drawn, the SOP slowly sinks to
0% and then the overload error is raised.
