How Many Amps for Electric Car Charger: The Basics
What Amperage Means for EV Charging
You may wonder how many amps for electric car charger you need. Amperage is the amount of electricity that flows from your charger to your car’s battery. This number matters because it controls how fast your battery fills up. If you choose a higher amperage, your electric car charging time goes down. Lower amperage means your car will take longer to charge.
Tip:
Amperage decides how quickly you can get back on the road. More amps mean less waiting.
- Amperage determines how quickly an electric vehicle can charge.
- Higher amperage allows for a greater flow of electrical current into the battery, reducing charging time.
You should always check your car’s manual to see the maximum amperage it can accept. Some cars can only take a certain amount, so a bigger charger will not always make charging faster.
Level 2 EV Charger Amps Explained
Level 2 ev charger amps are the most common choice for home charging. These chargers use more power than level 1 charging, which plugs into a regular wall outlet. Level 2 charging uses a special outlet and gives you much faster charging speeds. Most level 2 charger options range from 32 to 48 amps.
The table below shows how amperage affects charging time for popular electric vehicles:
| Amperage | Charging Time (5% to 80%) for Tesla Model Y Long Range | Charging Time (5% to 80%) for Hyundai IONIQ 5 | Charging Time (5% to 80%) for Volkswagen ID.4 |
|---|---|---|---|
| 24 amps | 10.6 hours | 9.7 hours | 10.4 hours |
| 32 amps | 8 hours | 7.5 hours | 5.2 hours |
| 40 amps | 6.4 hours | 5.8 hours | 6.2 hours |
| 48 amps | 5.3 hours | 4.9 hours | 5.2 hours |
You can see that a 40 amp charger or a 48 amp charger can cut your charging time by several hours compared to lower amperage. However, your car’s onboard charger may limit the speed. If your car cannot accept more than 32 amps, a higher amp charger will not make charging faster.
Level 2 ev charger amps also help you charge overnight. Most cars will be ready to go by morning. If you want even faster charging, you need a dc fast charger, but these are not usually installed at home.
