What affects lithium battery discharge current
If the discharge exceeds the maximum discharge current, the battery cell or BMS will be damaged, or the battery overcurrent protection will be triggered and the battery will have no output. But when plugged into the device, the entire cycle is reversed, and lithium ions are released by method and deposited on the anode, which causes the …
Short communication The effect of average cycling current on total energy of lithium-ion batteries for electric vehicles …
Moreover, battery capacity decreases with increased discharge rate as a battery reach the cut-off discharge voltage earlier [2], [8]. Therefore, it is a common practice among original equipment manufacturers (OEM) to de-rate battery power i.e. current, toward the lower SoCs to get access to remaining capacity [9].
Peukert''s law
Application at low discharge rates must take into account the battery self-discharge current. At very high currents, practical batteries will give less capacity than predicted with a fixed exponent. The equation does not take into account the effect of temperature on
