Warning and erorr messages
In case of an active error, the battery management system interrupts the battery charging /
discharging operation (see overview of error messages in Table 3). Note the hints in column
“Remarks / Measure”.
No.
Code
Meaning
Remarks / Measure
1
1
Overvoltage
Maximum cell voltage
BMS prevents further charging.
Battery discharge possible.
2
2
Undervoltage
Minimum cell voltage
BMS prevents discharging.
Battery charging possible.
3
4
Overtemperature
Cell temperature > 60°C: BMS interrupts
battery operation until system has cooled
off.
4
8
Undertemperature
Cell temperature < 0°C: BMS stops
charging.
Check environmental conditions (5° to
45°C).
5
16
Undertemperature
Minimum cell temperature discharging
< -10°C. BMS interrupts battery operation.
Check environmental conditions (5° to
45°C).
6
32
Overtemperature
BMS temperature > 90°C: BMS interrupts
battery operation until temperature is in an
acceptable range.
7
64
Deep discharge
Switch the BMS on by plugging in the
connection cable to the battery system and
apply the charging current.

Table 3: Error codes
Note: In case of multiple simultaneous errors the error codes will be summed up. Example:
overvoltage (Code 1) and overtemperature (32) => 1 + 32 = 33.
