Home Charging Is Already a Bargain — Here's How to Make It Even Cheaper

One of the most compelling financial arguments for electric vehicles is the cost of "fuel." Electricity is consistently cheaper per mile than gasoline in almost every region. But if you're not being strategic about when and how you charge at home, you could be paying more than necessary. These seven strategies can meaningfully reduce your monthly charging costs.

1. Switch to a Time-of-Use (TOU) Electricity Rate

Most utility companies offer time-of-use plans where electricity costs less during off-peak hours — typically late at night (11 PM–7 AM). Since most EVs can be programmed to begin charging at a specific time, this is one of the easiest wins available.

Off-peak rates can be 30–50% lower than peak rates in many markets. Contact your utility provider to ask about EV-specific TOU plans — many utilities offer dedicated EV rates that are even more favorable.

2. Use Your EV's Built-In Charge Scheduler

Almost every modern EV has a built-in charging scheduler accessible via the infotainment screen or companion app. Set your car to begin charging at the start of off-peak hours automatically — you don't need a smart charger to take advantage of TOU rates this way.

3. Invest in a Smart Home Charger

Smart Level 2 chargers go a step further than the vehicle's built-in scheduler. They allow you to:

  • Set charging windows based on your utility's rate schedule
  • Monitor exactly how much energy you use and what it costs
  • Participate in demand-response programs where your utility pays you to reduce load during grid stress events

The energy tracking alone helps identify inefficiencies and keeps your charging costs visible.

4. Take Advantage of Utility Rebates

Before purchasing a home charger, check with your electric utility for equipment rebates. Many utilities offer $100–$500 rebates on qualifying Level 2 charger purchases, and some offer installation rebates as well. State energy offices also run their own incentive programs. A quick search for "[your state] EV charger rebate" is worth the five minutes it takes.

5. Charge to 80% (Not 100%) for Daily Use

Charging to 100% every night is harder on your battery than staying between 20–80% for routine use. Most EV manufacturers recommend using 100% charges only when you need the full range. Charging to 80% not only protects your long-term battery health — it's also faster, since the last 20% of charging slows down to protect the cells.

6. Pre-Condition Your Battery While Still Plugged In

In cold climates, heating a battery to optimal operating temperature before departure uses significant energy. If that warming happens while the car is still plugged in (not running off the battery), you start every trip with a full charge and haven't lost range to cabin or battery heating. Set your EV's departure time feature to pre-condition on grid power automatically.

7. Add Solar to Charge During the Day

If you work from home or can shift some charging to daytime hours, rooftop solar can reduce your net charging cost to near zero during peak production months. Even a partial solar contribution — say, 30–50% of your weekly charging needs — meaningfully reduces your annual electricity bill. Pair solar with a battery storage system for round-the-clock solar charging capability.

Putting It Together

You don't need to implement all seven strategies at once. Start with the easiest wins: check for a TOU plan with your utility, set your car's charge scheduler, and look up available rebates before your next charger purchase. Each step compounds, and over the life of your EV, the savings add up to a substantial amount.

The bottom line: electric driving is already economical. With a little planning, it can be exceptionally so.
