Can I Leave My EV Charger Plugged In?

Electric vehicles (EVs) are becoming increasingly popular as a sustainable and eco-friendly mode of transportation. As EV ownership rises, many owners wonder about the best practices for charging their vehicles, including whether it is safe to leave their EV chargers plugged in when not in use. In this article, we will delve into this question and explore the pros and cons of leaving your EV charger plugged in.

The Benefits of Leaving Your EV Charger Plugged In

While it may seem counterintuitive, leaving your EV charger plugged in can actually provide several benefits.

Firstly, by keeping your charger connected to the power source, you ensure that your vehicle's battery remains topped up and ready for your next trip. This eliminates the need to remember to plug in your vehicle every time you park at home, saving you time and effort.

Moreover, many EV chargers come equipped with advanced features such as smart scheduling and monitoring. By leaving your charger connected, you can take advantage of these features, allowing you to optimize your charging schedule, track your energy consumption, and potentially save money on your electricity bill.

Additionally, leaving your EV charger plugged in enables remote access to charging data and control. Many manufacturers provide smartphone apps that allow you to monitor the charging progress, adjust charging settings, and even receive notifications when your vehicle is fully charged. This level of convenience and control is a significant advantage for EV owners.

The Downsides of Leaving Your EV Charger Plugged In

While there are benefits to leaving your EV charger connected, there are also considerations to be aware of.

One of the primary concerns is the potential for electrical hazards. If there is a fault in your charger or the electrical system, leaving it plugged in could pose a safety risk. It is essential to ensure that your EV charger and electrical infrastructure are properly installed and regularly inspected by a qualified professional. Regular maintenance and adherence to safety guidelines will significantly mitigate any potential risks.

Another disadvantage of leaving your EV charger plugged in is the standby power consumption. Even when not actively charging your vehicle, the charger will continue to draw a small amount of power from the grid. While this power usage might seem negligible, it can add up over time and contribute to unnecessary energy consumption. However, it is worth noting that modern EV chargers are designed to minimize standby power consumption, and the impact on your electricity bill is likely to be relatively low.

The Environmental Impact of Leaving Your EV Charger Plugged In

As conscientious EV owners, it is crucial to consider the environmental implications of leaving your charger connected when not in use.

On one hand, leaving your charger plugged in allows you to take advantage of renewable energy sources. By keeping your charger connected to the grid during periods of high renewable energy production, you can ensure that your vehicle is charged with green energy. This aligns with the overall objective of reducing carbon emissions and supporting a more sustainable future.

On the other hand, the standby power consumption of your EV charger can contribute to unnecessary energy consumption, particularly if your electricity is sourced from non-renewable sources. This energy consumption, albeit relatively small, can still have an impact on the environment and your carbon footprint. It is essential to strike a balance between the convenience of leaving your charger plugged in and reducing your overall energy consumption.

Best Practices for Leaving Your EV Charger Plugged In

If you decide to leave your EV charger plugged in, there are a few best practices to consider.

First and foremost, always ensure that your charger and electrical system are properly installed and comply with local safety regulations. Regularly inspecting your charger for any signs of damage or malfunction is crucial. If you notice any issues, it is best to disconnect the charger and seek professional assistance.

Consider utilizing the smart features and scheduling capabilities of your EV charger. Many chargers allow you to set specific charging times, taking advantage of off-peak electricity rates and minimizing standby power consumption. By programming your charger to operate during environmentally-friendly periods, you can reduce your carbon footprint and potentially save money on your electricity bill.

Lastly, it is advisable to keep an eye on your EV charger's temperature. EV chargers generate some heat while operating, and leaving it plugged in for extended periods without use can potentially lead to overheating. Regularly checking the charger and ensuring proper ventilation can prevent any potential issues.


In conclusion, leaving your EV charger plugged in when not in use can provide several benefits, including convenient access to charging data and ensuring your vehicle is always ready for your next journey. However, it is vital to be mindful of electrical hazards and standby power consumption. Striking a balance between convenience and environmental responsibility is key. By following the best practices and regularly inspecting your charger, you can enjoy the advantages of leaving it plugged in while minimizing any potential risks.
