Needed to be done. Optimal battery. Estimated battery life is done by comparing the average DoD (Depth of Discharge) battery, the amount of battery life cycle and the average daily cycle of the battery, and estimating the health level of the battery. The estimated lifetime of the battery with an average DoD level of 5.4% is 23 years 10 months 23 days with estimated battery levels or SoH (State of Health) 97.33396%. One test that can estimate battery life is by testing the battery with the open circuit voltage method or OCV (Open Circuit Voltage). Battery testing is carried out on 352 batteries arranged in series by measuring the open circuit voltage The battery is currently filled and measures the battery circuit voltage shortly after the battery is finished using a 50kW x 4 hour battery energy usage variation; 60kW x 2 hours; 50kW x 2 hours; 80kW x 2 hours; and 80 kW x 2 hours. The average SoH test level was 80.91909028%, the accuracy of the battery estimation of the battery SoH test was 81.46202655%.} }
