Common EV Charger Mistakes

When you get an electric car, it usually comes with its charger, right? But what’s surprising is that many folks aren’t entirely sure how to make the most out of their EV chargers. 

For a technology that is still relatively new to the general public, it’s understandable that mistakes are made. However, being informed can save you time, money, and potential hazards.

The Planning Pitfall

Failing To Think Ahead

If you own a EV, having a forward-thinking approach is important. One of the most common EV charger mistakes is failing to plan and strategise for charging needs, and there are consequences for failing to do so. 

Picture this: you’re in a hurry, running late for an important meeting or a family gathering, and your EV’s battery indicator is blinking red. You risk running low on power without a charging strategy at inconvenient times. A clear plan for when and where you’ll charge your EV can prevent these stressful situations.

With Australia’s EV charging infrastructure growing, it’s still not as widespread as traditional petrol stations. Not having a charging strategy can leave you limited access to charging stations, especially in less urban or remote areas. 

Not Checking If The Cable Is Long Enough

Another common mistake EV owners make is underestimating the importance of checking the charging cable length before purchasing. If your charging cable is too short, it can restrict where you can park your EV while charging. 

In many Australian cities, parking spaces can be tight, and not having the flexibility to reach your vehicle’s charging port comfortably can be frustrating. Home charging is the most convenient and cost-effective way to keep your EV topped up. 

However, if your charging cable is too short, you might need to park your EV in an inconvenient spot or even have an expensive electrician repositioning your charging equipment. Ensuring the cable length suits your parking setup is essential for hassle-free home charging.
