Charging Speed and Amperage
Charging Time by Amperage
You want your electric vehicle to charge quickly at home. The charging speed depends on the amperage of your Level 2 charger. When you increase the amperage, you allow more electrical current to flow into your EV’s battery. This can reduce the time it takes to charge your car.
- Higher amperage lets you fill your battery faster.
- Your charging station must deliver the amperage you need.
- Your EV must accept the higher amperage; some cars limit charging speed.
Let’s look at a typical 60 kWh battery. If you use a Level 2 charger with 7.2 kW output, you can expect these charging times:
| Battery Size | Estimated Time 0–100% on 7.2 kW | Typical Daily 20–80% Top-Up |
|---|---|---|
| 60 kWh (mainstream EV) | ~8.5 hours | ~4–4.5 hours |
You can see that a higher amperage charger can help you charge overnight or during the day. If you only need a daily top-up, you will spend less time plugged in.
Tip: Check your EV’s maximum charging speed before choosing a charger. Some cars cannot use the fastest chargers.
Real-World Charging Examples
You may wonder how charging speed changes for different EVs. Here are some real-world examples using Level 2 chargers at home and in public:
| Battery Size | Home Level 2 (7.2 kW) | Public Level 2 (11 kW) |
