Here's a comparison of cost savings between Level 2 and Level 1 EV chargers:
1. Energy Efficiency
Level 2 chargers operate at ~90% efficiency compared to Level 1's ~80%, meaning you waste less energy during charging. For every 1 kWh paid, Level 2 delivers 1.296 kWh to your battery vs. 1.152 kWh with Level 1.
2. Time-of-Use Optimization
Level 2 chargers enable strategic overnight charging when electricity rates are lower, while Level 1's slower charging often extends into peak-rate daytime hours. Many utilities offer night-time rates as low as $0.08-0.15/kWh for EV owners.
3. Reduced Public Charging Dependence
Faster home charging (4-10 hours vs. 12-16+ hours) minimizes reliance on expensive public stations, which often charge 2-4x residential electricity rates.
4. Long-Term Value
While Level 2 requires $500-2,000 installation costs, it improves home resale value and avoids the need for future electrical upgrades. Smart features like scheduled charging further enhance savings.
Cost Comparison Example
A 60kWh battery charging daily would save $100-300/year with Level 2 through efficiency gains and rate optimization, offsetting installation costs within 3-5 years.
