For lead-acid type batteries, an EODV is principally based on an EODV value that prohibits cell damage by over-discharge. Generally, EODV ranging between 1.750V and 1.80Vis utilized per cell when discharging time is longer than 1 hour. For short discharging time (<15 minutes), an EODV of about 1.66V per cell may be utilized without cell damage.

This particular factor accounts for voltage reduction during the discharge of the battery. In Lead-acid batteries, a voltage dip occurs in the early phases of battery discharge followed by certain recovery. System efficiency. It accounts for battery losses (coulombic efficiency) as well as power electronics losses (such as charger and inverter).

Lead-acid batteries show a characteristic with continuously decreasing voltage when discharged with constant current. The higher the discharge current, the greater the voltage drop. Figure 1 shows the modeled discharge profile for a 600 Ah cell loaded with varying power.
The calculation of the characteristic diagram is essential for discharging. Lead-acid batteries show a characteristic with continuously decreasing voltage when discharged with constant current. The higher the discharge current, the greater the voltage drop. Figure 1 shows the modeled discharge profile for a 600 Ah cell loaded with varying power.
Discharging your battery at a higher rate will increase the temperature in battery cells which as a result will cause power losses. e.g, a 100ah lead-acid battery with a C-rating of 0.05C (20 hours) will last about 20-25 minutes instead of 1

In the case of used battery it should be the State of Health multiplied by the Nominal Capacity. The output of the divide block is a Depth of Discharge, so it has to be subtracted from 1 to represent the State of Charge. The output value of this block is a SOC over time chart, example of which is presented in the figure 3.5.9.
Step 1: Collect the Total Connected Loads The first step is the determination of the total connected loads that the battery needs to supply. This is mostly particular to the battery application like UPS system or solar PV system. Step 2: Develop the Load Profile
The lead-acid battery performance is comparatively stable but reduces with the passage of time. Temperature correction factor: The battery cells capacity is generally provided for a standardized temperature which is 25oC and if it varies somewhere with the installation temperature, a correction factor is needed to implement.
The methodological analysis has the five steps as follows: Step 1: Collect the total connected loads that the battery requires to supply Step 2: Develop a load profile and further compute design energy Step 3: Choose the type of battery and determine the cell characteristics Step 4: Choose the battery cells required to be linked in series fashion
