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.
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.
The lithium-ion battery discharge test mode mainly includes constant current discharge, constant resistance discharge, constant power discharge, etc.
In this work, the behavior of different lithium-ion cells at different constant power discharge rates was investigated. Normal operational power loads as well as power loads above the specifications of the cells were tested to see if there is a correlation.
The discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan.
