Unplugging your EV charger when it’s not in use can indeed save a small amount of energy. Chargers, including home EV chargers, can consume a bit of standby power even when they are not actively charging a vehicle. This phenomenon is often referred to as "vampire power" or "phantom load."
For example, if you plan to use the device soon or if the device is not fully charged, it is okay to leave the charger plugged in. Additionally, if you are using a smart charger that automatically stops charging when the device is fully charged, it is not necessary to unplug the charger.
In such instances, leaving the EV charger connected when not actively charging could contribute to unnecessary energy usage. Users with concerns about energy efficiency may opt to unplug their charger during idle periods to mitigate standby power consumption and promote a more sustainable charging practice.
Ultimately, the decision to unplug the EV charger between charging sessions may be influenced by a combination of energy efficiency goals, safety concerns, and the specific features of the charger in use. Considering the standby power consumption of EV chargers is essential.
This power is used to maintain the connection between the charger and the device and can add up over time if multiple chargers are left plugged in throughout the day. By unplugging chargers when they are not in use, you can significantly reduce the amount of standby power being used and save on your energy bill.
Even when a device is fully charged or not in use, a charger that is plugged in will still use a small amount of power, known as standby power. This power is used to maintain the connection between the charger and the device and can add up over time if multiple chargers are left plugged in throughout the day.
