-EVE Power CO.,LTD Confidential Proprietary-
Charge Calibration:The charging mode described in 3.8 of this specification.
Discharge Calibration:The discharging mode described in 3.9 of this specification.
Open circuit voltage:The voltage of the cell measured when unloaded or circuit is disconnected.The
abbreviation is expressed by OCV
AC resistance:Apply 1kHz sine wave current between the positive and negative poles of the
cell,and the internal resistance obtained is AC resistance,which is abbreviated as ACR.The
test method is described in 3.6 of this specification
DC resistance:The ratio of the voltage changes to the corresponding current change under working
conditions,and the
abbreviation is DCR.The test method is as described in section 3.6 of this specification.
Module:The intermediate product between single cell and pack,which is formed by lithium-ion
cells in series and parallel after installing cell monitors and management devices.
Pulse current:The currents that appear periodically are called pulse currents.The puke currents
appear either in the same direction or in alternating positive and negative directions.
Compression force:When the module is assembled,the cell can withstand the force perpendicular to
the cell stacking direction.
Swelling force: The force on the clamp due to cell expansion during use,which may be caused by
inherent characteristic changes,such as the rebound electrode thickness.
