Temperature Ongoings (Heaters and Fans)
Lithium battery pack discharge and/or recharge, with
positive lithium battery level (SOC>0), is possible
over -10°C.
In cold environmental temperature (not lower than -
25°C), the on-board electric heaters automatically warm
up the cells, they are activated by the BMS when the
minimum cell temperature goes down 0°C, they are
automatically switched off when the minimum cell tem-
perature raises over the 2°C.
In case of battery charger is connected, till 0°C it sup-
plies only 3A in order to surely feeds only the heaters,
waiting positive temperatures to recharge the cells.
In cold environmental temperature (from -25°C to 0°C),
with null lithium battery level (SOC = 0), the heaters
work only while the cable is plugged to the electric net-
work (battery charger activated).
While heaters are working on the display will appear the
icon batteries cold, and machine could be moved only
in lower speed (turtle).
In hot environmental temperature, the fans system
automatically cool down the cells, they are automati-
cally activated by the BMS when cells temperature raises
over 37°C, they are automatically switched off when
cells temperature goes down the 35°C.
Diagnostics and Fault Codes
The main devices composing the lithium batteries sys-
tem are able to carry out self-diagnosis informing the
operator by the remote control display, in particular
they eventually display informative icons and provide
fault codes.
Self-diagnosis is carry out by:
•
BMS (Battery Management System)
•
Battery charger
•
Inverter
Further information about Lithium system, fault codes and
diagnose are detailed by Lithium system specific manual.
