6 FAQs about [Battery discharge current increases with load]
How does a high discharge rate affect a battery?
Higher discharge rates lead to increased internal resistance, resulting in more significant voltage drops. For instance, discharging at a rate of 2C can considerably reduce the battery’s capacity compared to lower rates. This information is vital for applications where peak power is needed, such as electric vehicles.
What causes a drop in voltage during battery discharge?
During discharge, batteries experience a drop in Vt. The drop in Vt is related to several factors, primarily: IR drop – The drop in cell voltage due to the current flowing across the battery’s internal resistance. This factor increases in a mostly linear slope at higher discharge rates, at a constant temperature.
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.
Why does the internal resistance of a battery increase with discharge current?
The internal resistance of the battery increases with the increase of the discharge current of the battery, which is mainly because the large discharge current increases the polarization trend of the battery, and the larger the discharge current, the more obvious the polarization trend, as shown in Figure 2.
What affects the change of battery discharge voltage?
The change of the battery discharge voltage is related to the discharge system, that is, the change of the discharge curve is also affected by the discharge system, including: discharge current, discharge temperature, discharge termination voltage; intermittent or continuous discharge.
What happens if a battery is discharged constant power?
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.
