Everything You Want to Know About EV Charging - My Adventure
Overview
There is only one kind of gas station but there are so many different EV charge stations. There are different charging networks and different equipment manufacturers and standards.
I will share with you my adventures at various EV charge stations and the mistakes I made. If there are people at the charge station ahead of you, you may not know what to ask yet, then, after other people leave, and it is your turn to charge, then there is no one around whom you can ask. Sure, you may feel embarrassed about asking questions, but you should be grateful if there is someone around the station who can explain things to you. When there was no one around, I had to spend a long time to figure things out myself. I really wished someone had made this kind of collection of videos for me to learn from.

Charging Station
Alternative Methods
There is more than one way to approach this task. Here are the most common methods, ranked by difficulty and cost.
Home Level 1 Charging
Plug into a standard 120V household outlet using the portable EVSE that came with your vehicle.
- Difficulty: Beginner
- Estimated Cost: $0 equipment (included)
- Notes: Slowest method — about 3-5 miles of range per hour — but zero installation cost
Home Level 2 Charging
Install a 240V outlet or hardwired EVSE in your garage for significantly faster home charging.
- Difficulty: Requires electrician
- Estimated Cost: $500-$2,000 installed
- Notes: Adds 25-30 miles of range per hour; ideal for overnight charging
Public DC Fast Charging
Use a DC fast charger (CCS, CHAdeMO) at public stations for rapid top-ups during road trips.
- Difficulty: Beginner
- Estimated Cost: $0.30-$0.60 per kWh
- Notes: Charges to 80% in 20-45 minutes; frequent use may degrade battery slightly faster
Tips and Common Mistakes
Avoid these pitfalls and use these tips to get the job done right the first time.
- Always check the charging station’s status on the network app before driving to it.
- Carry a Level 1 portable EVSE in your trunk as an emergency backup charger.
- DC fast charging to 80% is quick, but the last 20% takes almost as long — plan accordingly.
- Keep your charging port clean and dry — debris can prevent a solid connection.
- Cold weather reduces charging speed — precondition your battery when possible before fast charging.
- Check for free charging at dealerships, hotels, and municipal garages — many offer complimentary Level 2.
- Do not unplug other people’s vehicles at public stations — this is considered extremely poor etiquette.
Tools and Materials
| Item | Estimated Cost |
|---|---|
| Level 1 EVSE (120V, included with car) | $0 |
| Level 2 EVSE (240V, home install) | $200-$700 |
| 240V outlet installation (electrician) | $200-$800 |
| Charging adapters (J1772/Tesla) | $50-$200 |
| Extension cord (heavy-duty 12-gauge) | $30-$60 |
| Charging station app subscriptions | Free-$5/month |
When to Take It to a Mechanic
While most EV charging issues are user-error or station-side problems, see a professional if:
- Your vehicle will not accept any charge at home or public stations — the onboard charger or charge port may be faulty.
- Charging speed has dropped significantly compared to when the vehicle was new — battery degradation or thermal management issues.
- You smell burning or see scorch marks around the charge port — this is a safety hazard that needs immediate inspection.
- The 12V auxiliary battery dies frequently — EVs still use a 12V battery for accessories, and a failing one causes charging issues.
- Error codes appear on the dashboard related to the high-voltage battery system — never attempt to service the HV system yourself.
