How far can you charge in an hour?
-
Many people considering or already owning an electric vehicle (EV) often wonder about charging it efficiently. While charging can sometimes seem like a drawback, especially if you're in a rush, understanding how far your EV can go with a partial charge can alleviate these concerns. Knowing the range achievable with just a short charge can help you plan better and avoid delays.
Charging an EV can take anywhere from 30 minutes to over 12 hours, depending on the charging setup. This process is similar to charging a mobile phone: if you're short on battery, you might plug it in for 20 minutes for a quick boost, while overnight charging ensures a full battery.
How far can you drive after just one hour of charging?
The table below shows the distance you can drive with specific charger capacities after charging your EV for 30 minutes or 1 hour:
Distance in kilometers charged per hour
3.7kW Slow 7kW Fast 22kW Fast 43-50kW Rapid 150kW Rapid Up to 24 km Up to 48 km Up to 144 km Up to 144 km in 30 minutes Up to 321 km in 30 minutes The range achieved with just one hour of charging depends on the EV's efficiency. Smaller electric cars, such as the Renault Zoe, can gain up to 48 km of range per hour with a 7kW charger. Larger EVs, like the Audi e-tron Quattro, which are heavier, can achieve approximately 32 km per hour at the same charging rate.
It's also worth noting that hybrid vehicles, which use both electricity and fuel, are often less efficient than standard EVs. Efficiency can also vary depending on factors like weather. EVs generally perform better in warmer seasons, with summer offering slightly improved charging ranges compared to winter.
5 factors influencing charging speed:
1. **Battery size:** Larger batteries, measured in kWh, take longer to charge but provide more range when fully charged.
2. **Battery state:** The time needed to charge depends on the current charge level. Fully depleted batteries take longer than partially charged ones.
3. **Vehicle charging rate:** Charging speed is limited by the maximum rate the EV can accept. For instance, a car with a 7kW limit won't charge faster at a 22kW station.
4. **Charger capacity:** Charging time is also influenced by the power output of the charging station. For example, an 11kW-capable EV will only charge at 7kW at a 7kW station.
5. **Environmental factors:** Colder temperatures may slow down charging, especially with rapid chargers. Conversely, higher temperatures may reduce EV efficiency, impacting range during charging.
To maximize your EV's potential and avoid inconvenient situations when you need to travel but the battery is low, identify compatible charging stations for your vehicle and understand how far you can drive after a short charge. Keep in mind the five factors mentioned above, as they also influence charging speed.
