Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
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.
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. To understand the discharge characteristic curve of a battery, we first need to understand the voltage of the battery in principle.
The relationship between the battery's average voltage, average discharge current and battery energy capacity can be seen in Figure 5. In terms of time it can be observed that the greater the load resistance value, the longer the battery discharge time. ...
The nature of the load (constant current, constant power, or variable load) affects how the battery discharges. Constant power loads, for example, will lead to a different voltage drop pattern compared to constant current loads. 8. Internal Impedance:
