How does Voltaback determine the price of home charging?

Written by Marine Bourdain

Voltaback is the only solution on the market able to reimburse home charging at the employee's actual rate. Voltaback relies directly on the driver's electricity bill to calculate the exact kWh price.

Voltaback retrieves rates from the electricity bill

When setting up their account, the driver uploads their most recent electricity bill. Our system automatically extracts:

  • the kWh price

  • the rate structure (standard rate, peak/off-peak hours, Tempo, EJP, etc.)

  • the exact peak/off-peak time windows from the meter

All contract types are supported, including specific rates like Tempo or EJP.

Why reimburse at the actual rate?

  • A fairer cost for the company — off-peak hours are taken into account, which are often cheaper than a flat rate based on regulated pricing.

  • Better compliance with URSSAF rules — the reimbursement matches the driver's actual expenses exactly, with no over- or under-reimbursement.

What happens if the electricity rate changes?

Voltaback asks the employee to update their contract once a year, to keep the most recent rates on file. If the driver changes contract, they can update their bill directly from their Voltaback driver account.
