Car Is Limiting Charging Speed
Your vehicle is deliberately charging slower than the charger allows
The charger is capable of more power but your car is only accepting a fraction of it. This is almost always your car's battery management system protecting the battery. It is usually normal, not a fault.
Your situation
You are connected to a fast charger but your car's dashboard shows it is only accepting a fraction of the available power. The charger is not the bottleneck, your car is.
What to try first
- 1
Check the battery temperature
If the battery is too cold or too hot, the car will reduce charging speed. In cold weather, use battery preconditioning by navigating to the charger through your car's built-in nav. The car will warm the battery on the way.
- 2
Check the state of charge
Above 70-80%, all EVs slow down charging significantly. This is normal and protects battery health. The charging curve is steepest between 10-50% and drops off above that.

Check for any vehicle warnings
Some cars display a warning when they limit charging. Check your dashboard for messages about battery temperature, conditioning, or reduced power. These are informational, not errors.

Frequently asked questions
Is it bad that my car limits charging speed?
No. This is a feature, not a bug. Your car's battery management system reduces charging speed to protect battery health and longevity. Charging at maximum speed when the battery is very cold, very hot, or nearly full would damage the cells over time.
How can I get faster charging speeds?
Arrive at the charger with a warm battery (use preconditioning) and charge between 10-70% state of charge. Avoid charging to 100% at fast chargers. In cold weather, drive for at least 20 minutes before charging to warm the battery naturally.
