The lead-acid battery discharge curve equation is given by the battery capacity (in ah) divided by the number of hours it takes to discharge the battery. For illustration, a 500 Ah battery capacity that theoretically discharges to a cut-off voltage in 20 hours will have a discharge rate of 500 amps / 20 hours = 25 amps.
The discharge curve basically reflects the state of the electrode, which is the superposition of the state changes of the positive and negative electrodes. The voltage curve of lithium-ion batteries throughout the discharge process can be divided into three stages
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 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.
When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. 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.
Sealed lead-acid batteries are generally rated with a 20-hour discharge rate. That is the current that the battery can provide in 20 hours discharged to a final voltage of 1.75 volts per second at a temperature of 25 degrees Celsius.
