Supercharge Your Savings - How MeterHome™ Powers Your EV for Pennies

Audience: External (Public)

Purpose: To clearly demonstrate the significant financial savings an EV owner can achieve by using a MeterHome™ BESS to charge their vehicle with low-cost, off-peak electricity.

You Love Your EV. But Do You Love When You Charge It?

Owning an electric vehicle is a fantastic way to save on fuel costs and help the environment. But when you charge your car can make a huge difference in your electricity bill. If you're like most people, you probably plug in your EV when you get home from work—right in the middle of your utility's "On-Peak" hours, when electricity is most expensive.

What if you could charge your car every night using only the cheapest power available, without changing your routine at all? With a MeterHome™ system, you can.

The Problem: Expensive "On-Peak" Charging

Let's look at a real-world example here in Tualatin with Portland General Electric's Time of Day plan.

  • On-Peak Rate (5 PM - 9 PM): 43.89¢ per kWh
  • Off-Peak Rate (after 9 PM): 9.08¢ per kWh

The average American drives about 30 miles per day. A typical EV uses about 10 kWh of energy to cover that distance.

If you plug in your car at 6 PM, you're paying the highest possible price for that energy.

Cost to Charge During Peak Hours: 10 kWh x 43.89¢/kWh = $4.39 per day Over a year, that's over $1,600 just to charge your car.

The Solution: MeterHome's Smart Energy Shifting

Your MeterHome™ system is intelligent. It knows when power is expensive and when it's cheap. It allows you to shift your energy usage completely, charging your car with Off-Peak power even if you plug it in during Peak hours.

Here's how it works:

  1. Your MeterHome BESS charges during the day with your own solar power or from the grid during the cheapest Off-Peak hours. It fills its 14.3 kWh "energy tank" with the least expensive energy possible.
  2. You plug in your EV when you get home at 6 PM, during the expensive On-Peak window.
  3. Instead of pulling that expensive power from the grid, your EV charger pulls power directly from your MeterHome battery.
  4. Your car gets the 10 kWh it needs for your daily commute, powered by the cheap energy you stored earlier.

The Result: Over 75% Savings on Charging Costs

By using your MeterHome system to charge your EV, you are effectively paying the lowest possible rate for your daily "fill-up."

Cost to Charge with MeterHome (using Off-Peak Power): 10 kWh x 9.08¢/kWh = $0.91 per day

Let's compare the annual costs:

  • Charging without MeterHome (Peak Rates): ~$1,602 per year
  • Charging with MeterHome (Off-Peak Rates): ~$332 per year

Annual Savings on EV Charging: ~$1,270

By adding a MeterHome BESS to your home, you're not just getting backup power and a lower electric bill—you're turning your garage into the cheapest gas station in town. You can enjoy the convenience of plugging in your EV whenever you want, knowing your system is smart enough to give you the best possible price, every single time.
