Homeowners: Schedule EV Charging and Save with a 9.6–11.5kW Level 2

Yes, you can schedule your EV to charge automatically in the cheapest off-peak window, and departure-time scheduling is the best way to do it. Set a “ready-by” time in your vehicle app, smart charger app, or third-party app, then pair it with your utility’s off-peak plan. Get those three pieces working together and you lower your electricity cost while easing strain on the grid during peak demand hours.

TL;DR:

Using a departure time to schedule EV charging maximizes savings by starting the charge as late as possible while still finishing before departure.

The optimizer calculates start time based on battery capacity, current charge level, charger power, and efficiency, typically allowing overnight charging to complete during off-peak hours.

Most utilities’ off-peak hours occur between midnight and 7 a.m., but it is essential to verify your specific utility’s schedule and seasonal shifts to avoid higher rates.

Level 2 chargers with higher power output, such as 9.6kW or 11.5kW, are recommended for longer or more complex charging requirements, especially if off-peak windows are short.

If scheduled charging fails, checking connectivity, using override options, and contacting your utility can resolve most issues without disrupting savings.

How Do You Schedule EV Charging Step by Step?

Most drivers set a fixed start time and call it done. That works, but it leaves savings on the table. A departure time is smarter because the vehicle or charger calculates backward from when you actually need the car, so it starts as late as possible while still finishing before you walk out the door.

Here’s how to set it up tonight:

Open your vehicle’s app (or the in-dash menu) and look for “Charging Schedule” or “Departure Time,” not just “Start Time.” Enter the time you typically leave in the morning.
Set weekday and weekend patterns separately. Most apps let you build two schedules since your Tuesday commute and Saturday errands rarely start at the same hour.
Configure a finish-by time in your smart charger app if your charger has its own scheduling layer, and set it to overlap with your utility’s off-peak window.
Build a default “charge only during off-peak hours” rule, then allow manual exceptions for road-trip days or unplanned errands.
Plug in every time you park, even if the battery is at 70%. The schedule can only do its job if the cable is connected.
Verify the session is scheduled by checking the app’s status screen. It should show a scheduled start time or a countdown, not just “connected.”

Departure-time scheduling also tends to net more savings than a static start time because it can factor in preconditioning and shifting rate windows, according to the EV Charging Schedule Optimizer from ChargeCalcs.

How Does an App Calculate Your Charging Start Time?

The math behind any good scheduling tool is simpler than it looks. It runs backward from your departure time using four inputs:

Usable battery capacity (in kWh)
State-of-charge delta (how much you need to add, from current percent to target percent)
Charger power (in kW, based on your circuit’s amperage and voltage)
Charging efficiency (some energy is lost as heat, typically accounted for as a percentage loss)

The formula: energy needed divided by charger power equals charging duration. Subtract that duration from your departure time, and you get your start time.

Here’s a real-world example. A 75 kWh battery charging from 30% to 80% on an 11.5 kW charger needs roughly 3 hours and 37 minutes of wall energy once efficiency losses are factored in. If your off-peak window opens at 11 p.m. and you leave at 7 a.m., the optimizer has plenty of room to start late and still finish early.

Quick reference: most Level 2 chargers deliver somewhere around 25 to 30 miles of range per hour, which is why a modest overnight window covers most daily driving without touching peak rates.

When Is the Best Time to Charge an EV on Your Utility Plan?

Off-peak hours vary by utility, but many run from roughly midnight to 7 a.m., according to research on residential EV charging patterns. You cannot assume your off-peak window without checking, because it changes by provider and sometimes by season.

To find and enroll in a time-of-use plan:

Log into your utility’s account portal and search for “EV rate” or “time-of-use” under rate plans.
Call customer service if nothing appears publicly. Some EV rates require proof of vehicle ownership and are not listed on the general rate page, since rate structures are sometimes gated behind an enrollment process.
Watch for seasonal shifts. Peak windows can move earlier in winter when evening demand for heating and lighting spikes.

PG&E, for example, offers EV2-A and EV-B rate plans with clearly defined off-peak and peak hours built specifically for EV owners. If your utility changes its peak window seasonally, you’ll need to nudge your departure time or finish-by setting to match, or you’ll spill into more expensive hours without realizing it.

Pro Tip: Set a calendar reminder every six months to recheck your utility’s TOU schedule. Rate windows shift more often than people expect, and a forgotten schedule update can quietly erase months of savings.

Is Level 1 Enough, or Do You Need a Level 2 Charger?

Level 1 charging, using a standard household outlet, typically adds only a few miles of range per hour. That’s fine if you drive under 30 miles a day and have all night to charge. But if your commute runs long or your off-peak window is short, Level 1 often can’t finish before peak rates kick back in.

Level 2 charging changes the math entirely:

A 40A (9.6kW) Level 2 setup delivers roughly four to five times the speed of Level 1, comfortably fitting most daily charging into a single overnight window.
A 48A (11.5kW) Level 2 setup pushes that further, which matters if you’re topping off a larger battery or sharing one charger across two EVs in the household.
If your current off-peak window is too short for your battery size, upgrading from Level 1 to a 7.7 kW or higher Level 2 circuit usually compresses the session enough to avoid spillover into peak hours.

Installation involves a dedicated 240V circuit, and code considerations fall under NEC Article 625, so it’s worth consulting a licensed electrician before you commit to a plug type or amperage, especially for a hardwired installation. Chargeprodirect’s EVIQO Level 2 chargers cover the range from 40A plug-in units for cost-conscious upgrades to 48A hardwired units for households that want maximum overnight throughput.

Can You Schedule Charging Without a Dedicated Home Charger?

Not everyone has a driveway and a breaker panel to work with, and scheduling still matters even without a private Level 2 setup.

In apartments and condos, ask your building manager whether shared stations run on a rotation schedule or a first-come system, and whether resident charging windows can be requested.
At public chargers, treat sessions as top-ups rather than full charges when convenient, and use your vehicle’s schedule override for urgent same-day needs rather than waiting on a shared unit.
As a renter, ask your landlord about a dedicated outlet or a portable Level 2 unit that plugs into an existing 240V line, since some setups require no permanent wiring changes at all.

Should You Prioritize Solar or Off-Peak Rates?

If your home generates midday solar surplus, schedule charging to run then rather than waiting for overnight off-peak rates. You’re using power you’ve already paid for through your solar investment instead of buying it back from the grid later.

If you don’t have solar, overnight TOU charging is almost always your cheapest option.

A home battery system can shift your household’s load so EV charging happens whenever electricity is cheapest, solar surplus or overnight off-peak, without ever touching peak-rate hours.
Some smart chargers and home energy systems offer a toggle between “solar-first” and “TOU-first” modes, so check your charger’s settings before assuming it’s picking the right source automatically.

What Do You Do When a Charging Schedule Fails?

A missed schedule is usually a small glitch, not a big problem.

Check connectivity first. Both the vehicle and the charger need an active Wi-Fi or cellular link to authenticate and start on schedule.
Use a one-time “charge now” override instead of deleting your recurring schedule when you need power immediately. Most systems support temporary overrides that don’t erase your regular pattern.
Reboot the charger and re-save your home location if sessions repeatedly fail to start, and contact your utility directly if your TOU enrollment doesn’t seem to be applying to your bill.

Pro Tip: *If your plug-in time is shorter than the charge actually needs, most optimizers just start as soon as you connect.

How Chargeprodirect Helps You Build a Charging Schedule That Saves Money

Some EV charging platforms help homeowners match charger amperage to their household’s actual driving needs and utility rate structure, not just whatever unit happens to be in stock. The goal is a setup where your off-peak window and your charger’s speed actually line up. For sizing or installation questions, the EV Charger Placement guide and installation resources are good starting points before you buy.

Get the Charging Speed That Actually Fits Your Off-Peak Window

An advantage of specialized EV charger retailers is providing Level 2 units sized to actual off-peak windows and battery sizes instead of guessing at amperage and hoping the charger finishes before peak rates hit. A 9.6kW or 11.5kW charger closes the gap between a short overnight window and a full charge, which a standard Level 1 outlet usually cannot do.

If your commute or battery size means Level 1 keeps spilling into peak hours, the EVIQO Level 2 EV Charger, 48A Hardwired delivers maximum throughput for a permanent install. Want a plug-in option instead? The EVIQO 48A NEMA 14-50 charger gives you more flexibility. On a NEMA 14-50 outlet, set it to 40A. The full 48A requires hardwiring on a 60A circuit. For households balancing cost against speed, the EVIQO 40A Level 2 charger still cuts charging time dramatically versus a standard outlet. Browse the full Level 2 home charger lineup and check installation cost expectations before you order, so you know exactly what to expect from quote to plug-in.
