## The Economics of Efficiency

In the B2B electric mobility space, efficiency is a direct operational expense.

### ROI / TCO Model
For a fleet of 100 on-board chargers (11kW, 4 hours/day charging, 10 years):
A gain from 96% to 97.5% efficiency results in:
- **Total Energy Saved**: ~240,000 kWh
- **Operating Cost Reduction**: ~$36,000 (at $0.15/kWh)
- **Sustainability Impact**: 170 Tons of CO2 prevented.

### eDrift's Efficiency Advantage
By minimizing the switching loss in our MOSFETs, we achieve a flat efficiency curve even at partial load scenarios.
