AC-DC Charger Power Loss Calculator
This calculator optimises EV charger designs by calculating critical power losses due to power conversion and cable resistance, which are essential for maximising energy transfer and minimising operational costs in electric vehicle infrastructure.
Enter the AC Input Power, PFC Efficiency, DC-DC Conversion Efficiency, Cable Resistance, Cable Length and DC Output Current to calculate power loss in onboard/offboard chargers.

This calculator uses input parameters like voltage, current, efficiency ratings, and cable lengths for instant power loss insights, enabling smarter power electronics selections for sustainable charging solutions.
Example:
For a Charger with Input Power 11 kW, PFC Efficiency of 98%, DC-DC Conversion Efficiency of 95%, Cable Resistance of 0.00001 Ω/m, Cable Length of 5 m and DC Output Current of 16 A,
PFC Power Loss = 11 x (1-0.98) = 0.22 kW
DC-DC Conversion Loss = (11 x 0.98) x (1-0.95) = 0.539 kW
Cable Power Loss = (16)2 x 0.00001 x 10 = 0.0256 kW
Total Power Loss = 0.22 + 0.52 + 0.026 = 0.7846 kW
