6.4.13
Nominal temperature {6020}
The battery parameters are specified for a given temperature by their manufacturer. This
parameter makes it possible to modify that temperature.
6.4.14
Temperature coefficient {6021}
The available capacity diminishes with the decrease of the temperature. This coefficient enables
to take this factor into account.
6.4.15
Charge efficiency factor {6022}
During charging, less Ah are stored into the battery than during discharging. The ratio
discharge/charge can be set with this parameter.
6.4.16
Peukert's exponent {6023}
The capacity varies according to the discharge current (see section 1.1.4). With this parameter,
one can set the Peukert exponent that goes along with the nominal capacity {6001} and nominal
discharge time.
6.4.17
Use C20 capacity as reference value {6049}
The calculation of the SOC algorithm is based on the capacity achieved during a 20h discharge
(C20) which is set using parameters {6001}, {6002} and {6023}. When this parameter is set to "no",
the capacity of parameter {6001} is used.

ONFIGURATION AS SIMPLE COUNTER
When using other battery technologies than lead it is necessary to configure the BSP as a simple
counter without correction. It is necessary to activate the "end of charge synchronisation" to
avoid the state of charge to derive due to measuring errors and loss of battery capacity. The
parameters can be modified as follows:
