7.4.5 Technical details regarding energy management
The device will work until 3,1V, if the NivuLog Easy is operated without an external charging voltage (V
in
). It
then switches to energy-saving mode in which only the charge controller is active. If an external charging
voltage (V
in
) is supplied in this mode, the accu pack can be charged up again. Otherwise the NivuLog Easy
remains in energy-saving mode until the accu pack is completely discharged.
When an external charging voltage (V
in
) is used, the charge controller ensures that the accu pack is charged.
It is therefore necessary to select the type of accu used in the input screen of the device configuration (see
"Device-specific settings" on page 62). If a type of accu pack is selected that is also assigned the title "solar",
the accu pack is constantly charged (recommended if a solar field is used to charge the accu pack). For all of
the other accu pack type settings, the accu pack is always charged to the maximum voltage, after which
charging is switched off and only reactivated when V
low
(see "Device-specific settings" on page 62) is
reached (used to optimise the service life of the accu pack).
All types of accu packs are only recharged if the ambient temperature does not have an impact on the
permissible range of the charging temperature. The permissible charging temperature is specified in the
factsheet for the relevant accu pack. Chapter "Accu and battery packs" on page 71 contains an overview of
the temperature ranges for several accu packs.
Note:
Please be aware that some of the compatible accu packs cannot be charged at sub-zero temperatures.
Select an appropriate accu pack if you are expecting low temperatures during operation.
