The Best Time to Charge an Electric Vehicle at Home

Switching to an electric vehicle (EV) is exciting and brings with it the responsibility of learning new habits—like figuring out the best time to charge. Deciding when to charge isn’t just a matter of plugging in whenever you get home. From saving on costs to preserving battery health, the timing of charging your EV can make a big difference.

As a leading EV charger manufacturer based in China, MOREDAY is here to help you make smart decisions on charging practices that optimize your experience. In this guide, we’ll walk you through everything you need to know to choose the best time to charge an electric vehicle at home, balancing cost, convenience, sustainability, and battery life.

Peak vs. Off-Peak Charging: Cost and Convenience

When it comes to EV charging, timing is everything. Not only can charging at specific times reduce your energy costs, but it also helps stabilize the grid by spreading out electricity demand.

Dual-Rate Tariffs and Off-Peak Rates

Many utility companies now offer what’s known as “time-of-use” (TOU) or “dual-rate” tariffs. These are electricity plans where the rates vary depending on the time of day. For example, electricity rates are typically lower during off-peak hours—usually late at night or early morning—when fewer people are using electricity. By charging your EV during these hours, you can save a significant amount on your electricity bill.

Here’s a quick look at how charging costs can differ:

How Much Can You Save?

Charging during off-peak hours can save you as much as 30% to 50% on your electricity bill. That’s money you could be spending elsewhere. Plus, with MOREDAY’s smart EV chargers, you can schedule charging to start only during off-peak hours, so you don’t even have to be awake to start saving.

Battery Health Best Practices

Keeping your EV battery in top shape is crucial for longevity. While you might be tempted to top it off every night, charging every single day may not be necessary and could reduce battery life in the long run.

The Optimal Charging Range

Most EV experts recommend keeping your battery between 20% and 80%. This “sweet spot” range helps maintain battery health. Regularly charging up to 100% is only recommended for long trips where you’ll need the extra range. Sticking to this range can extend your battery’s lifespan and minimize wear.

Slow vs. Fast Charging

While fast charging is convenient when you’re in a hurry, using it too frequently can be hard on your battery. Slower charging (like with Level 1 or Level 2 chargers) is gentler on the battery, allowing it to hold its charge longer. MOREDAY’s Level 2 home chargers are designed for efficiency, balancing charging speed with battery preservation.

Environmental Impact and Sustainability

Charging your EV isn’t just about cost and convenience; it also has an environmental impact. Believe it or not, the time you choose to charge can affect how eco-friendly your vehicle truly is.

Charging with Renewable Energy

If you’re one of the many homeowners with solar panels, you’re in luck. Daytime charging during peak sunlight hours allows you to power your EV directly from solar energy, which means your ride is fueled by the sun. Even if you don’t have solar panels, charging during lower-demand times reduces strain on the grid and increases the likelihood that your EV is running on cleaner energy.

Reducing Carbon Emissions

When everyone charges their EV at night, the grid faces a higher load during off-peak hours. While this might seem efficient, studies suggest that spreading out charging times to include more daytime hours could reduce strain on the grid. Charging during times when renewable energy sources like wind and solar are most active can help reduce your carbon footprint.

Climate Considerations for Efficient Charging

Temperature plays a big role in the charging efficiency and health of your EV battery. Extreme heat or cold can affect battery performance and longevity.

Temperature Effects on Charging

In warmer climates, charging at cooler times of the day—like early morning or late evening—can help maintain battery health. Batteries charge more efficiently at moderate temperatures, so if you’re in a particularly hot area, waiting until the sun goes down might be best for your EV. Conversely, in colder regions, charging during the warmer part of the day can reduce the strain on your battery.

Regional Recommendations

If you live in an area with significant temperature fluctuations, it’s worth adjusting your charging schedule to these conditions. Warmer climates? Stick to late-night or early-morning charging. Colder climates? Try charging during midday when it’s a bit warmer.

Lifestyle Fit: Choosing a Charging Time Based on Daily Routine

Your EV charging routine should fit seamlessly into your lifestyle. Let’s take a look at how different routines might influence the best time for charging.

For Commuters

If you drive daily to work or run errands, charging overnight can ensure a fully charged battery each morning. It’s convenient, and with off-peak rates, it’s also cost-effective. This approach also saves time since you’ll never be waiting around for your EV to charge.

Remote Workers or Low Mileage Drivers

If you work from home or don’t drive often, you might not need to charge every day. Charging during midday, especially if you have solar panels, allows you to take advantage of renewable energy. It’s also convenient if you’re home and don’t need the car immediately.

Home vs. Workplace Charging Options

Where you charge your EV can also play a big role in your charging habits and costs.

At-Home Charging Convenience

Charging at home is the most convenient option for many. MOREDAY’s Level 2 chargers can be installed at home, providing faster charging and reducing reliance on public stations. Plus, with a smart charging option, you can schedule your charger to only operate during off-peak hours, ensuring you save on costs automatically.

Workplace Charging as an Option

For those who can charge at work, this can be a great alternative. Some employers even offer free or subsidized charging for employees, and if your workplace offers lower rates or renewable energy sources, this can make your daily commute even more sustainable and affordable.

Conclusion: Finding Your Ideal Charging Schedule

Choosing the best time to charge your EV ultimately comes down to balancing cost, convenience, and sustainability. For many, nighttime charging during off-peak hours is both affordable and easy. However, if you’re able to charge during the day, particularly if you have access to solar energy, it’s an eco-friendly alternative that supports sustainability.

Whether you’re looking for cost savings, convenience, or battery health, MOREDAY’s range of home chargers can help you charge efficiently and effortlessly. And remember, finding a routine that works for you is key to making the most of your EV ownership experience.

FAQs

• While convenient, it’s best to only charge nightly if necessary. Frequent charging can wear down the battery, so try to keep it between 20%-80% unless needed for long trips.

2. What’s the cheapest time to charge my EV?

• Generally, the cheapest time to charge is during off-peak hours—typically late at night. Check with your utility provider to confirm exact times and rates.

3. Is fast charging bad for my EV battery?

• Regular use of fast charging can impact battery health over time. It’s best to use slow or Level 2 chargers for routine charging and reserve fast charging for when you’re short on time.

4. How does charging during the day impact the environment?

• Daytime charging, especially with solar power, helps reduce grid strain and emissions by aligning your energy use with renewable sources.

5. What’s the best way to extend my EV battery life?

• Keep your battery level between 20%-80%, avoid frequent fast charging, and try to charge during moderate temperatures when possible.
