Charging Etiquette and Best Practices
EV charging is becoming more widespread, but with that comes the need for good charging etiquette to ensure everyone has a fair and efficient experience. Here are some key points of etiquette and best practices to follow when using public charging stations.
1. Don’t Hog Charging Stations
Best Practice: Only use public chargers when you need to. If you’re charging at a fast-charging station, avoid leaving your car there for extended periods after it's finished charging. This allows others to charge their vehicles, particularly when stations are in high demand.
2. Unplug After Charging
Best Practice: As soon as your car is fully charged, unplug it and move it to a regular parking spot. Many charging apps and stations will notify you when your vehicle has finished charging to help you stay on top of this.
3. Be Courteous in Emergencies
Best Practice: If someone else is in urgent need of a charge and you have enough range to get to another station, consider letting them charge first, especially at fast chargers.
4. Avoid Blocking Chargers
Best Practice: Don’t park in charging spots unless you’re actively charging your vehicle. Blocking a charger can inconvenience other EV drivers and slow the flow of traffic at charging stations.
5. Use the Right Charger for Your Needs
Best Practice: If you don’t need a fast charge, consider using a Level 2 charger instead of occupying a fast-charging station. This keeps the faster chargers available for those who are on longer trips and need a quick top-up.
