3.5. 

Passive Safety Protection     

 
3.5.1.  Overview of Operations 
 
The battery pack is fitted with additional components to protect it 
against  abusive  charge  and  discharge  conditions.  These  are  in 
addition to the electronic protection. 
 
3.5.2.  Thermal Fuse 
 
A Thermal Fuse is fitted in series with the charge/ discharge path to 
protect the  battery  from  over  temperature.  This device  goes open 
circuit  if  the  cell  case  temperature  reaches  the  fuse's  temperature 
rating  of  93°C  (+0°C,  -5°C).  The  fuse  is  non-re-settable  rendering 
the battery pack non-functional.
