Why is the amount of energy on my bill higher than on my car?

When you charge your Electric Vehicle, you might notice a slight difference between the amount of energy the charging station says it delivered and the amount of energy your car's dashboard says it received.

This is completely normal! Here is a quick breakdown of why this happens:

The "Leaky Bucket" Analogy

Think of charging your car like filling a bucket with a garden hose:

  • The Charger measures how much water flows out of the hose.
  • Your Car measures how much water actually lands in the bucket.

During the process, a little bit of water naturally splashes out.

Why does this happen?

Power from the grid has to be converted into a form of power your car's battery can actually store.

  • Where the energy goes: This conversion process creates a small amount of heat, which is where that "splashed water" goes.
  • What to expect: On a standard Level 2 charger, it is completely normal to lose up to 20% of the energy to this conversion process. The exact amount depends on your specific vehicle and the weather conditions.

What are you paying for?

Our charging stations measure and bill for the total energy delivered by the charger to your vehicle. We cannot track how much energy is lost once it enters the vehicle's internal systems.

Summary: You are billed for the total energy sent from the station, but your car's dashboard only displays the energy that successfully made it all the way into the battery after the natural conversion losses. Because this conversion happens inside your car, our chargers can only measure and bill for the total energy delivered to the plug.
