What is the typical charging voltage for a lithium-ion battery?
Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. Cut-off Voltage: This is the minimum voltage allowed during discharge, usually around 2.5V to 3.0V per cell.
What is a constant current discharge of a lithium ion battery?
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
What happens when a lithium ion battery discharges?
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.
What is a discharge curve in a lithium ion battery?
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages
What happens if a battery reaches a low voltage threshold?
To prevent over discharge of cells and resulting damage, battery managements system will terminate discharge if any of the cells reached low voltage threshold. Cell based termination voltage is usually set to lower value than pack based threshold divided by number of serial cells, so that the difference can allow for a small unbalance.
How many lithium ion battery cells need to be connected in series?
The details are as follows. The voltage of a single lithium-ion battery cell is low. If 3.2 V LFP cells are adopted, 160 cells need to be connected in series to provide the battery voltage of 512 V DC. The charge and discharge currents (I) of the cells connected in series are the same.
