EVs have been around for over two decades now. People have been driving them for a while and the demand for EV chargers has been going up as more people start purchasing EVs. The demand for EVs is going up and so companies like ChargePoint, Tesla, EVgo, Electrify America, Blink Charging, and Wallbox started to offer charging stations that can be installed at home. Having one at home will save you time, you just come home and plug it in and leave it to charge overnight.
All these services are widely available for people but because they are new, people still don’t know how they work, how long they last, what the installation cost is, maintenance and other important things to remember when you decide to have a charger at home. This is exactly what we will discuss in this post.
The Installation Process
1. Choose the Charger Type
- Level 1– Plugs into a standard 120 V household outlet. It’s the simplest option but slow (adds ~3–5 miles of range/hour).
- Level 2– Requires a 240 V circuit (like a dryer outlet) and is far faster (~20–30 miles of range/hour). This is the most common for home installations.
Note: True “DC Fast” (Level 3) chargers usually aren’t practical for residential installs — they are expensive and require industrial electrical infrastructure.
2. Electrical Assessment
A licensed electrician evaluates your home’s electrical panel and determines:
- Available amperage.
- Whether the panel needs upgrading (common in older homes).
- Optimal location for the charger near the panel.
Permits and city inspections are typically required to ensure compliance with local and National Electrical Code standards.
3. Installation & Wiring
A professional:
- Runs dedicated wiring from your panel to the charger location.
- Installs a dedicated breaker and GFCI protection as required.
- Completes wiring, mounting, and testing.
- Coordinates inspection and switches the circuit live.
Most installations are completed in a single day (4–8 hours), though complex jobs needing panel upgrades can take longer.
How Much Does Installation Cost in Naperville, IL?
The cost of an EV charger depends on a few things like the type of charger, the electrical panel you already have, the distance from the panel to where you want to have the charger installed, and if you will need a new electrical panel installation in case it won’t be strong enough to handle the charger. Local electricians report that they’ve seen specific panel issues in older homes near downtown Naperville. Below is a breakdown with more information for your reference:
Typical local cost ranges:
- Level 1 charger + simple install:~$180 – $300 for the unit alone; installation potentially minimal if no upgrades.
- Level 2 charger + installation:~$800 – $2,500 typical, depending on electrical work needed.
- Some local reports show Level 2 charger install + hardware around $1,300 – $1,400.
Rebates & Incentives
- City rebate: Up to $500 for residential Level 2 installations.
- Utility rebates (ComEd): $1,000 – $3,750 possible for qualifying projects.
- Federal tax incentive: 30% of cost up to $1,000 — but note potential legislative changes that could impact availability in 2026.
Rebates can significantly reduce out-of-pocket expenses — sometimes by thousands of dollars.
| Cost Component | Typical Price Range |
| EV Charger Unit (Level 1) | $180 – $300 |
| EV Charger Unit (Level 2) | $400 – $800 |
| Basic Installation Labor | $400 – $800 |
| Electrical Permit & Inspection | $100 – $300 |
| Long-Distance Wiring / Trenching | $200 – $1,000+ |
| Electrical Panel Upgrade (if needed) | $1,500 – $3,500 |
| Total Typical Level 2 Install (No Panel Upgrade) | $800 – $1,400 |
| Total Level 2 Install (With Panel Upgrade) | $2,000 – $2,500+ |
Lifespan: How Long Do Chargers Last?
The local electricians at Cob Services in Naperville, IL, report that a home charger usually lasts for around 10 – 15 years — and in many cases it can last for up to 20 years, depending on the brand and how often it’s used.
Here are some factors that will impact the lifespan of charger:
- Weather exposure (outdoor units need high ingress protection ratings).
- Heavy daily use vs. occasional charging.
- Thermal cycling and electrical load on the internal components.
Tip: Indoor installations generally outlast outdoor ones due to less environmental stress.
Maintenance & When to Replace
Routine Care
- Visual inspection of cable, connectors, and housing for wear or damage.
- Check mounting hardware for loosening over time.
- Keep connectors and contacts clean and dry.
- Update smart charging firmware if available.
Industry sources suggest annual maintenance checks or service every couple of years to catch early wear.
Signs It’s Time to Replace
- Charger fails frequently or won’t communicate with the vehicle.
- Physical damage or water intrusion observed.
- Charging speed degrades significantly.
- Manufacturer ceases support or replacement parts are unavailable.
Generally, if your charger is older than 10–15 years and shows persistent issues, it’s more cost-effective to install a new unit than repair an obsolete one.
Where Chargers Can’t Be Installed Easily
Certain homes face barriers to a typical charger install:
1. No Dedicated Parking or Accessible Wall
Homes with only street parking — e.g., townhomes without garages or driveways — may need public charging or specialized sidewalk/pole chargers, which often require utility permission and trenching.
2. Insufficient Electrical Service
Older homes with only 100-amp service may require electrical panel upgrades to support a 240 V Level 2 charger safely — otherwise breaker trips or overloads can occur.
3. Condo/HOA Restrictions
In shared buildings or HOA communities, any wiring or exterior hardware typically requires board approval and coordination with the building’s electrical infrastructure.
4. Historic or Permitted Properties
Homes in historic districts may need special permits for exterior work, adding time and cost.
Best Home EV Charger Brands (Level 2)
Choose hardware that’s reliable, future-proof, and compatible with most EVs:
Top Recommended Models
- ChargePoint Home Flex: Flexible amperage, smart features, broad EV compatibility.
- JuiceBox 40 / 48: Strong weather protection and energy tracking options.
- Wallbox Pulsar Plus: Compact smart charger with app control and long cord options.
- Grizzl-E Classic: Rugged, reliable and lower cost.

Final Ideas
Getting your first electric vehicle is a big change. You pay less for power than you would pay for gas. According to Argonne National Laboratory’s study, electric vehicles (EVs) are cheaper to own than gasoline vehicles over a 15-year lifespan. The study found that EVs cost about 45.0¢ per mile, while gasoline vehicles cost about 49.0¢ per mile.
So, whether you got an EV because you really like it, or to save more through Naperville’s $500 rebate, this post is an introduction on what it is like to get an EV home charger installed. What maintenance it needs, how much it costs and more.
