Looking for the real source of truth in home charging? EEVEE knows what really matters!
Some claim that measuring consumption via the vehicle can deviate by 5 to 20%.
As a result, certain providers point to MID-certified charging stations as the only reliable source, within the legally permitted margin of 2%. But it's important to understand that
the only true reference point for reimbursement is the home energy meter — because
that’s what actually records the electricity consumed and forms the basis for accurate reimbursement.
So what is the correct reference?
The only system that knows exactly how much electricity was consumed is the employee’s home energy meter. That’s what the energy bill is based on — whether digital or analog. This is also why the government’s circular on home charging reimbursement is crystal clear:
“The circular clarifies that the use of a charging station or MID certification is not required, as long as the reimbursement is based on an objective, verifiable calculation with a maximum deviation of 2% compared to the home energy meter.”

Additional insight via the EEVEE App
In addition to this official measurement data, the EEVEE app gives you extra insights.
We show how much of the electricity that entered through the charging port actually
made it into the battery.
This data is purely informational, but offers valuable insight into:
• The vehicle’s charging efficiency
• The quality of the charging session

Why measuring via the vehicle offers additional benefits
1. Always real-time
No waiting times, no synchronisation, and no extra hardware. Our data is live 24/7.
2. Based on official OEM data
EEVEE reads data through an official connection with the vehicle — directly from global automotive manufacturers. It doesn’t get more trustworthy than this.
3. VIN-based detection
All measurements are 100% linked to the vehicle’s chassis number.This guarantees that
the electricity went into the correct company car — not into your partner’s or neighbour’s.
A charging station simply can’t verify that.

How EEVEE measures what really matters — Fully within
the legal standard
EEVEE doesn't measure how many kWh end up in the vehicle’s battery, but how much electricity actually flows through the vehicle's charging port. Just like with a charging station, our measurement may deviate by no more than 2% from the home's energy meter.Here’s what that means in practice:
• Charging station ↔ energy meter: max. 2% deviation allowed
• EEVEE ↔ energy meter: max. 2% deviation allowed
• Charging station ↔ EEVEE: up to 4% potential difference between the systems
⚠️ Important: Reimbursements via EEVEE are always based on the measurement
at the charging port, and never deviate more than 2% from the home’s energy meter
— fully compliant with legal requirements.

Electric vehicles convert alternating current (AC) into direct current (DC) to charge the battery. This conversion process causes heat loss and results in an efficiency of about
75% to 95%, depending on the car brand (OEM).
These losses are not a flaw of any measurement system — they are a universal feature
of EV charging, and they occur with both charging stations and EEVEE.
EEVEE measures at the charging port — not in the battery, where the conversion process can lead to brand-dependent energy loss. Only the charging port measurement forms
the basis for reimbursement, and always stays within 2% of the employee’s home energy meter.

The conclusion? Choose to measure at the source!
MID-certified charging stations are perfectly fine — but they’re not required, and they’re not more reliable than EEVEE. The law doesn’t require hardware — only accurate measurements within a 2% margin of error.
And that’s exactly what we guarantee — fully compliant, with added benefits for both companies and employees.
🟢 Want to reimburse home charging correctly and flexibly? Then measuring via the vehicle is not just the best solution — it also provides greater insight, without the need for extra hardware.
