5 Myths About Home EV Chargers You Need to Stop Believing

Do you own an electric car or are you thinking of making the switch? Before deciding how and with what to charge at home, there are several misconceptions circulating in forums, Facebook groups, and garage conversations that could lead you to make a bad decision. At EcoCargadores, we have been advising individuals and businesses for years, and these are the 5 myths we have had to debunk most often.

Myth 1: "A slow charger isn't worth it"

This is perhaps the most widespread misunderstanding. Many EV owners think that if they don't install the most powerful charger on the market, they are wasting their time. The reality is very different.

A 7.4 kW home charger is capable of fully charging an average EV (50-60 kWh battery) overnight. If you're like most drivers and travel less than 60 km a day, this type of charger perfectly meets your needs: you get home, plug in the car, and the next morning your battery is ready.

Installing a higher power charger (11 kW or 22 kW) can mean a significantly higher electrical installation cost and not provide any real benefit in daily use.

Myth 2: "Charging your car every night damages the battery"

It's understandable that this comes from the world of mobile phones and laptops ten years ago, where constant charging to 100% did degrade the battery. Modern electric vehicles have evolved significantly.

The vast majority of current electric cars incorporate a battery management system (BMS) that intelligently regulates charging. You can program the charging limit to 80% for daily use and reserve 100% for long trips. Charging every night with these settings not only doesn't damage the battery, but it is the most recommended way to use it.

Myth 3: "You need to do major construction to install a charger"

Another common deterrent that causes many EV owners to continue using a conventional outlet longer than necessary. In practice, installing a home charger in a private garage is a simple process:

Assessment of the existing electrical panel.

Cable run from the panel to the charging point.

Mounting the charger on the wall.

Configuration and functional testing.

In most cases, a certified electrician can have it ready in a few hours, without masonry work or major renovations.

Myth 4: "All home chargers are the same"

This myth can be costly. Choosing a charger without considering your real needs is one of the most common mistakes we see. Key differences between models include:

Power: 3.7 kW / 7.4 kW / 11 kW. Determines charging speed.

Connectivity: WiFi, mobile app, time scheduling to take advantage of off-peak rates.

Dynamic load management: adjusts power according to household consumption.

Compatibility: ensure the connector and protocol match your vehicle.

Myth 5: "Charging at home is more expensive than at public chargers"

Nothing could be further from the truth, especially if you take advantage of electricity rates with time-of-use discrimination. Charging at night (generally from 10:00 PM to 8:00 AM), the price per kWh can be 4 or 5 times lower than that of a public fast charger.

To put it in numbers: a full 50 kWh charge at home during off-peak hours can cost you between €3 and €5. The same process at a 50 kW public fast charger can exceed €15-20. Over the course of a year, the difference is very significant.

Conclusion: get well-informed before deciding

For most EV owners, having a home charger is the best investment they can make for everyday use. But to get the most out of it, choosing the right model and a correct installation is key.
