The charging station or the charger is an external device that supplies the electric energy to the vehicle. Its main role is to convert AC (Alternating Current) power from the grid into DC (Direct Current) to charge the electric car’s battery. There are different types of chargers, from the basic Level 1 that uses a standard household outlet, to the high-powered Level 3 or DC Fast Chargers that are commonly found in public locations.

The power source is typically your home electricity supply or a public charging network. Depending on the charger you’re using, the power source can significantly affect charging speed. For instance, a Level 1 charger might take 8-14 hours to fully charge a depleted battery, while a Level 3 charger can do the same in just 20-30 minutes.

Lastly, the electric vehicle’s battery is what stores the electrical energy from the charger. Its capacity, measured in kWh (Kilowatt-hours), largely determines the vehicle’s driving range.

Now that we understand the basic process of charging an electric car, let’s explore the most common charging problems and their relevant solutions.

Identifying Common Electric Car Charging Issues

Familiarizing yourself with the common electric car charging issues is a crucial step in maintaining a seamless charging experience. Here are some of the most frequently encountered problems.

Charging Speed is Slower Than Expected

One common issue is that your electric car charges slower than promised. This could be due to various factors, including the charger’s power output, the vehicle’s onboard charging capacity, the battery’s state of charge, and the ambient temperature. It’s essential to ensure that the charger you’re using matches your car’s charging capacity. Moreover, remember that charging speed slows down considerably as the battery reaches its full capacity to preserve its longevity.

Charging Station is Not Working

Another common problem is coming across a public charging station that’s out of order. This is usually signified by a red light or an error message on the station’s display. It could be due to a network issue, a software glitch, or a hardware malfunction. In such cases, it’s best to report the problem to the operator or try another nearby station.

Difficulty Connecting to the Charging Network

You might also find it difficult to connect to the charging station’s network, especially if it relies on a mobile app or a card for activation. This could be due to a data issue or a software problem on the operator’s end. If you’re facing this problem, try restarting the app or check if there are any reported network issues.

With these common issues in mind, let’s explore the solutions and how you can troubleshoot these problems.

Fixing Electric Car Charging Issues

Most charging issues can be resolved with a bit of knowledge and sometimes a little hands-on approach, so let’s look at some of the fixes.

Charging Speed Issues

If you’re dealing with slower-than-expected charging speeds, check your charger’s power output and ensure it matches your car’s onboard charger capacity. Also, keep an eye on your battery’s state of charge—the last 20% usually takes much longer to fill up. If it’s extremely cold or hot, your battery may charge slower to prevent damage. In such cases, consider warming up or cooling down your car before plugging it in.

Non-Functioning Charging Stations

If you stumble upon a non-functioning charging station, contact the station’s operator. They should be able to assist you or direct you to another nearby station. Some EV models like Tesla have their supercharger network with reliable customer service to address any issues swiftly.

Network Connection Problems

If you’re having trouble connecting to the charging station’s network, try restarting the app or your phone. If the problem persists, contact the network provider and inquire about any ongoing issues. They might be able to provide you with an alternative way to activate the charger, such as a toll-free number.

Upgrading Your EV Charging Experience

While troubleshooting is a critical skill for any EV owner, taking proactive steps can significantly reduce charging related issues.

Investing in a Home Charging Station

Investing in a home charging station can significantly enhance your charging experience. Not only does it save you from relying on public charging infrastructure, but it also allows you to charge whenever it’s convenient for you. Plus, with smart chargers, you can schedule your charging sessions during off-peak hours to save on electricity costs.

The Role of Charging Infrastructure and Car Batteries

An electric car’s charging infrastructure is crucial in providing a successful charging session. Whether it’s at home or a public charging station, the infrastructure should be robust and efficient to offer quick and reliable charging. Home charging stations are typically Level 2 chargers that use a 240-volt outlet, much like a clothes dryer. These can fully charge an electric vehicle overnight. Public charging stations, on the other hand, often offer Level 3, or DC Fast Chargers, that can charge most electric cars to about 80% in just 20 minutes.

However, the infrastructure is only one part of the equation. The car battery also plays a massive role in the electric vehicle charging process. All electric vehicles come with a lithium-ion battery pack that stores the power needed to run the car. These batteries vary in size and power, which can affect how quickly they charge.

For instance, a larger battery with a higher kWh (kilowatt-hour) capacity will take longer to charge than a smaller one. Also, as batteries age, their ability to hold a charge decreases, increasing the time it takes to charge them. It’s also important to note that continuously charging the battery to full can degrade its health over time. To maintain the longevity of your car battery, it’s recommended to keep the charge between 20% and 80%.
