How to Understand Battery C-Rate

For example, a battery with a nominal capacity of 100 Ah (C 10 capacity for a 10hour discharge), when discharged with a 10 A current (C/10 rate) will take 10 hours to discharge the battery fully. However, if the same battery is discharged with double the current (20 A), due to the internal losses, the discharge time would not be the expected 5 hours, but a

6 FAQs about [Battery discharge high current]

What is a constant current discharge in a battery?

At the same time, the end voltage change of the battery is collected to detect the discharge characteristics of the 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.

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 is battery discharge rate?

The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.

What happens if a battery is discharged too much?

As we mentioned above, excessive discharge current can cause the battery to generate a large amount of heat, leading to oxidative decomposition of the electrolyte and reconstruction of the SEI, leading to delamination of the active material layer and causing a damage on the crystalline structure of NCM cathode.

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 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.
