Lithium-ion Battery Pack BMS
BMS (10 cells)
1. Lithium Ion Battery Pack Functions:
Overcharge Detection Function--the negative electrodes of both the charger and the cell is disconnected when the voltage of any cell is over 4.25V± 0.025V.
Overcharge Resumption Function— the negative electrodes of both the charger and the cell is reconnected when the voltage of the protected cell is lower than 4.15V± 0.025V. The overcharge protection is finished and a normal charge process resumes.
Overdischarge Detection Function-- the negative electrodes of both the charger and the cell
is disconnected when the voltage of any cell is lower than 2.70V± 0.025V.
Overdischarge Resumption Function— the negative electrodes of both the charger and the
cell is reconnected when the voltage of the protected cell is over 3.00V± 0.025V. The overdischarge protection is finished and a normal discharge process resumes.
Overcurrent Detection Function---the fuse will be cut out and the discharge circuit will be cut
off when the current is over the set value. (also can be modified as current limitation
function due to customers' requirements. )
Overheat Detection Function-performed by PTC; the circuit will be cut off when cells' temperature is over the set value. (optional)
