Interval (hours) = (C × DoD) / (L / η) Let's put this into practice. A 100kWh battery at 80% DoD powering a 20kW load with 90% efficiency? You'd get: (100 × 0.8) / (20 / 0.9) = 3.6 hours. Easy as π, right? [pdf]
This power loss dissipated as heat is calculated according to the formula, P HEAT LOSS = I 2 R, where I is the current passing through the battery and R is the internal resistance of the battery. This formula is originally obtained through the formula for power, which is, P= VI. [pdf]
Calculate power density using: Power Density (W/kg) = (Voltage × Current) / Battery Mass. For example, a 3.7V battery discharging at 50C rate (150A for a 3Ah cell) with a mass of 0.1kg has power density = (3.7V × 150A) / 0.1kg = 5,550 W/kg. [pdf]
