The only way that a battery manufacturer can insure the safety of a battery is if a switch is included in the battery and the BMS has full control of that switch.
The Li-ion batteries in the Dreamliner do include a BMS, but do not include a switch (the output terminals are always live). Therefore, if the BMS did detect a problem, it was powerless to fix it, as it had no switch to turn off.
On the contrary, Elithion batteries do include a switch, that is off by default, unless the BMS turns it on when it sees that the battery is safe. That is true of Elithion’s traction packs and of Elithion’s Lithiumod battery modules.
Therefore, Elithion can correctly claim that its battery packs are inherently safe.
