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.

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.

What happens if a battery has a high discharge rate?

Higher discharge rates will lead to lower voltage. According to the basic principle of battery energy (the product of battery capacity and battery voltage), the amount of electricity released by a battery at high discharge rates is greater than that released at low discharge rates.

What is a maximum continuous discharge current?

Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

Battery Charging and Discharging Parameters

However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is ...
