Battery Charger Calculator

Battery Charger Calculator

Estimate the charging time using: $$ T = \frac{C \times \left(\frac{SOC_{\text{final}} – SOC_{\text{initial}}}{100}\right)}{I \times \eta} $$

* Ensure battery capacity is in Ah, current in A, and efficiency is entered as a fraction (e.g., 1.0 for 100%).

Step 1: Enter Battery Parameters

e.g., 100 Ah

e.g., 20%

e.g., 80%

e.g., 10 A

e.g., 1.0 for 100% efficiency

Charging Time Formula: $$ T = \frac{C \times \left(\frac{SOC_{\text{final}} – SOC_{\text{initial}}}{100}\right)}{I \times \eta} $$
