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 temperature raises over the 2°C.
In case of battery charger is connected, till 0°C it supplies 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 network (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 automatically 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 system 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 training.
