Charging speed
Effective output is the lower of your charger's rated output and your vehicle's maximum onboard AC charging rate. A 48A charger (11.5 kW) paired with a vehicle that accepts only 7.7 kW will charge at 7.7 kW — buying a bigger charger won't help.
Electricity cost
Based on your vehicle's battery size, EPA range, and daily miles driven. We use the real energy-per-mile ratio from the battery spec rather than a generic kWh/100mi estimate. Actual costs vary by driving conditions, temperature (cold reduces EV range), and your utility's rate structure.
Gas savings
Assumes 25 MPG and $3.50 per gallon for a comparable ICE vehicle. Your actual savings depend on your real MPG and local gas prices — adjust accordingly.
Installation cost
Estimates reflect typical Minnesota residential jobs — charger unit, labor, conduit, dedicated circuit, permit filing, and inspection. Longer conduit runs, panel upgrades, or trenching can increase cost. We provide a fixed-price quote before any work begins.
