Driving electric is the future—but charging at home shouldn't be complicated. K.O. Electric provides professional EV charger installation throughout Coeur d'Alene, Post Falls, Hayden, and North Idaho, helping homeowners make the switch to convenient, fast home charging. Whether you drive a Tesla, Rivian, Ford Lightning, or any other electric vehicle, we'll install the right charging solution for your needs and ensure your electrical system can handle it safely.
If you own an electric vehicle, you already know the benefits: lower fuel costs, reduced emissions, and smooth, quiet driving. But charging at public stations is inconvenient and time-consuming. A home EV charger transforms your garage into your personal charging station—plug in when you get home, wake up to a fully charged vehicle every morning.
Convenience & Time Savings
No more planning trips around charging stations or waiting 30-60 minutes at public chargers. Home charging happens while you sleep, so your EV is always ready when you are.
Lower Cost Per Mile
Charging at home costs significantly less than public charging or gasoline. In Idaho, electricity averages around $0.10-0.12 per kWh, giving you the equivalent of $1-2 per gallon fuel costs.
Faster Charging Than Standard Outlets
A standard 120-volt outlet (Level 1) adds only 3-5 miles of range per hour. A Level 2 home charger adds 25-40 miles per hour—meaning you can fully charge overnight instead of waiting days.
Increase Home Value
As EV adoption grows, home buyers increasingly expect EV charging capability. Installing a charger now adds value and makes your home more attractive to future buyers.
Support Your Electrical System
Professional installation ensures your panel, wiring, and circuit can handle the electrical load without overloading your system or causing safety issues.
Understanding charging levels helps you choose the right setup for your vehicle and driving habits.
Level 1 Charging (120-Volt Standard Outlet)
What it is: Plugging your EV into a regular household outlet using the charging cable that came with your vehicle.
Charging speed: 3-5 miles of range per hour (40-50 miles overnight)
Best for: Plug-in hybrids, low daily mileage (under 30 miles), or backup charging
Limitations: Far too slow for most EV drivers with daily commutes or larger battery packs
Cost: Free (uses existing outlet)
Level 2 Charging (240-Volt Dedicated Circuit)
What it is: A hardwired or plug-in EV charger connected to a 240-volt circuit—the same voltage as your electric dryer or oven.
Charging speed: 25-40 miles of range per hour (full charge in 4-8 hours)
Best for: All-electric vehicles, daily commuting, households with one or more EVs
Power requirements: 40-50 amp dedicated circuit, 240-volt connection
Cost: $500-1,500 installed (equipment + electrical work)
Most Popular: This is what 95% of EV owners install at home
DC Fast Charging (Level 3)
What it is: Commercial-grade charging stations found at public locations—not installed in homes due to extreme power requirements (up to 350 kW) and cost ($50,000+).
Charging speed: 80% charge in 20-40 minutes
Best for: Road trips and public charging infrastructure
The bottom line: If you drive an all-electric vehicle, a Level 2 home charger is essential for practical daily charging. We'll help you choose the right charger and ensure your electrical system can support it.
Choosing the right charger depends on what you drive now—and what you might drive in the future.

We'll help you select the right charger for your needs during your free consultation.
Many North Idaho homes—especially those built before 2000—have 100-amp electrical panels that can't handle a Level 2 EV charger without an upgrade.
Understanding EV Charger Electrical Requirements
A Level 2 EV charger draws 40-50 amps continuously while charging. That's nearly half the capacity of a 100-amp panel. If your home also runs central AC, electric heat, or other high-demand appliances, a 100-amp panel simply can't handle the additional load safely.
Signs You Need a Panel Upgrade Before Installing an EV Charger
Your home has a 100-amp electrical panel (check the main breaker—it should say "100" or "200")
Circuit breakers trip frequently when running multiple appliances
Your panel is older (30+ years) or uses fuses instead of breakers
You plan to install multiple EV chargers (for a second vehicle)
Your home addition or recent remodel already pushed your electrical capacity
The 200-Amp Solution
Upgrading to a 200-amp panel provides plenty of capacity for your EV charger plus all your home's current and future electrical needs. Most EV charger installations in older homes require this upgrade.
Timeline: 2-4 weeks (includes utility coordination and permitting)
Long-term benefit: Supports future electrical needs, increases home value
During your free consultation, we'll assess your electrical panel and let you know if an upgrade is needed. We handle the entire process—panel upgrade, charger installation, permits, and inspections—so you don't have to coordinate multiple contractors.
Installing a home EV charger is straightforward when you work with experienced electricians who understand EV charging requirements.
Step 1: Free Consultation & Electrical Assessment (30-60 minutes)
We'll visit your Coeur d'Alene, Post Falls, or Hayden property to assess your electrical panel capacity, discuss your vehicle and charging needs, and recommend the right charger and installation approach. You'll receive a detailed quote covering equipment, installation, permits, and any necessary panel upgrades.
Step 2: Charger Selection & Ordering (1 week)
Once you approve the quote, we'll help you select the right EV charger for your vehicle and order the equipment. If your panel needs upgrading, we'll coordinate that timeline as well.
Step 3: Permit Application (1-2 weeks)
We handle all electrical permit applications with Kootenai County, Bonner County, or your local building department. EV charger installations require permits to ensure code compliance and safety.
Step 4: Installation Day (4-8 hours)
Our licensed electricians will install your dedicated 240-volt circuit, mount the EV charger in your garage or carport, connect all wiring to code, and test the system to ensure it's working properly. If a panel upgrade is needed, that's typically done first.
Step 5: Inspection & Final Testing (1-2 days after installation)
We'll schedule the required electrical inspection with your jurisdiction. Once approved, we'll walk you through using your new charger and answer any questions about optimal charging practices.
Most EV charger installations are completed within 2-4 weeks from approval to final inspection. Rush installations for new EV purchases can often be expedited—call us at (208) 618-1459 to discuss your timeline.
EV charging isn't just about installing an outlet—it's about ensuring your entire electrical system can safely support your vehicle's charging needs.

Q: How much does EV charger installation cost in Coeur d'Alene?
A: EV charger installation typically costs $800-1,500 total, including the charger equipment ($300-700) and installation labor ($500-800). If your electrical panel needs upgrading, add $2,000-4,000 for the panel upgrade. We provide free, detailed quotes for all projects.
Q: How long does EV charger installation take?
A: The actual installation takes 4-8 hours. The full process from approval to final inspection typically takes 2-4 weeks due to permitting and equipment ordering. If a panel upgrade is needed, plan for 3-5 weeks total.
Q: Do I need a permit to install an EV charger?
A: Yes, EV charger installations require electrical permits in Kootenai County, Bonner County, and all city jurisdictions throughout North Idaho. K.O. Electric handles all permit applications and coordinates inspections as part of our service.
Q: Can I install an EV charger if I have a 100-amp electrical panel?
A: It depends on your home's current electrical load. Many 100-amp panels are already near capacity and can't safely support an EV charger. We'll assess your panel during the consultation and let you know if an upgrade to 200-amp service is needed.
Q: Will an EV charger work with any electric vehicle?
A: Universal J1772 chargers work with all EVs except Tesla (though Tesla owners can use them with an included adapter). Tesla Wall Connectors only work with Tesla vehicles unless you purchase a separate adapter. We'll help you choose the right charger for your vehicle.
Q: How fast will my EV charge at home?
A: With a Level 2 (240-volt) home charger, most EVs add 25-40 miles of range per hour of charging. A typical EV with a 250-mile range can fully charge overnight in 6-8 hours. Actual speed depends on your vehicle's onboard charger capacity and the amperage of your EV charger circuit.
Q: Can I install a second EV charger for another vehicle?
A: Yes! We can install multiple EV chargers in the same garage. Your electrical panel will need sufficient capacity (usually 200-amp service minimum), and we may recommend load-sharing technology to optimize charging between vehicles.
