Introduction: Why Smart EV Charging Matters
The number of electric vehicles is expected to reach 230 million by the end of the decade. As government and utility companies continue to invest in electric car charging points, the demand is to make these chargers faster and more efficient. This is where smart charging comes in.
Smart EV charging is a system that monitors, manages, and limits charging stations to optimize energy consumption. It allows you to control when and how fast your EV is charged, helping to optimize energy consumption, reducing charging costs, and facilitating the integration of renewable energy sources.
This article will help you understand the best practices for charging electric vehicles (EVs) and proper maintenance culture in a public charging station.
Understanding Your Charging Options
Home Charging vs Public Charging
- Home Charging: Home EV charging is the most convenient option for EV drivers. It makes use of a standard 120V outlet, but charges at a very slow rate. This charging option is perfect for overnight charging or users that work from home.
- Public Charging: This mode of charging is perfect for long-distance drivers or people without reliable home charging access. Public stations are faster than home EV chargers, making them ideal for urban commuters.
While most homeowners prefer getting a wall charger for electric cars, public charging is faster.
Level 1 vs Level 2 Charging
- Level 1: This type of charging uses a standard household outlet. It is the slowest option, often adding just 3-5 miles of range per hour of charging.
- Level 2: The level 2 EV charger runs on a 240V outlet or a wall unit and delivers 12-60 miles of range per hour, depending on your EV model. This is the most practical solution for most drivers, balancing speed with efficiency.
There’s another level of charging after level 2, which is DC fast charging. This type of charging can provide up to 80% charge in 30 minutes.
Best Practices at Public Electric Vehicle Charging Stations
Using public electric car charging points is not just about plug and charge, you have to follow certain etiquettes to ensure a positive experience for drivers. Here are the best practices when at a public electric vehicle charging station:
Planning Charging Routes
Unlike gas stations, electric car charging points are not available at every corner. So, knowing where and when to charge makes all the difference. To plan your charging route, follow these tips:
- Use EV charging maps or apps: Tools like PlugShare, ChargePoint, Google Maps, etc. will help you locate charging stations along your route. Check real-time availability, charger type, and compare costs to choose the best option for you.
- Look for fast charging stations on long trips: DC fast charging stations can add significant range in under 1 hour, making them ideal for long-distance travel.
- Have a backup option: Always have an alternative charging point in case your first option is offline or occupied.
Etiquette at Charging Stations
Some rules to follow at public EV charging stations include:
- Only park if you are charging: Do not use charging spots for parking unless your vehicle is plugged in and charging.
- Unplug when finished: Once your car is finished charging, unplug the cords and move your vehicle to free up the space.
- Never unplug another vehicle: Unless you have the owner’s permission, do not disconnect someone else’s car.
- Keep cords tidy: After charging, return the cord to its holder to prevent damage and ensure the next driver can plug in easily.
- Respect the time limit: Many public EV charging stations have designated time limits for charging. It is important to stick to these limits to ensure equal charging access to all drivers.
Maximizing Charge Time
Here are some tips to maximize EV charging:
- Precondition your battery: Many EVs allow you to heat or cool your battery before arriving at a charger. This helps your battery charge faster and more efficiently.
- Charge between 20%-80%: EV batteries charge faster at lower levels. Charging from 20% to 80% is faster and healthier for battery life than waiting for a full 100%.
- Choose the right charger: Use DC fast chargers when you’re on a trip or need a quick top-up and level 2 chargers for routine charging.
Maintenance of EV Charging Equipment
According to the U.S Department of Energy (DOE), general maintenance for charging infrastructure is essential for a smooth and efficient charging operation. Here are some recommended maintenance tips:
Charging Cables Maintenance
Physical damage to your cables can affect charging performance. This is particularly true for level 2 and DC fast chargers. Some damages such as burns and exposed wires need to be addressed immediately. Proper charging cable maintenance includes:
- Avoid dragging cables on the ground to prevent wear and tear.
- Store cables on wall-mounted holders to prevent damages.
- Inspect regularly for cracks, fraying, and exposed wires.
Cleaning Connectors
Wipe down your EV charger with a dry cloth each week. Pay attention to the connectors so they can attach securely to the EV’s charging port. Key maintenance tips for connectors include:
- Keep connectors free from dust, dirt, and moisture.
