An energy report for a company car is a short document built from the charger’s session records: the period’s total kWh, the company share of that total, your own tariff, and the arithmetic connecting them — handed over with the session list attached. For a company car also used privately, the split is a share agreed with the employer in advance, usually the company proportion of the car’s mileage.
Key Takeaways
- A company-car report is the session total, the company share, your tariff, and the arithmetic — with the session list attached.
- A dedicated charger needs no split; a mixed-use car splits by its company share of mileage, agreed in advance.
- Show the working every month in the same layout; label the figures as the tracking estimates they are.
- The method and the tax treatment are your employer’s policy and your tax adviser’s call — never a rate this article can state.
What the Report Is Made Of
- The session record. This charger’s app logs each session with its energy in kWh, measured at the charger. That log is the report’s evidence — the household meter cannot separate the car from the house.
- Your tariff. The per-kWh price from your own electricity bill for the same period — there is no standard rate a report can borrow.
- The split. Which part of the home-charged energy belongs to the company — worked out as the next section sets out.
- The agreed method. Your employer’s policy decides whether the split is acceptable; a tax adviser settles how the payment is treated.
The Two Splits a Report Can Use
| Your situation | The split | What the report shows |
|---|---|---|
| The charger serves only the company car | No split needed — every session in the log is company energy | The period total from the session list, priced at your tariff |
| One car, mixed company and private use | Company share of mileage applied to the home-charged total: company miles ÷ total miles × total kWh | Both mileage figures, the percentage, the total and the resulting company kWh — the calculation visible |
A worked example, with an invented tariff to show the shape: in one month the charger logs 320 kWh at home. The car covered 1,200 miles, 900 on company business — a 75% share. The company portion is 240 kWh; at an example tariff of €0.35 per kWh, that is €84.00. Your figures replace every number here; the layout is the point. Where two cars share one charger, sessions must be attributable to a car: our guide to RFID and user management for shared chargers covers chargers that log per user.
Hand Over the Arithmetic, Not Just the Total
A report that shows its working survives questions; one showing only a final figure invites them. Send the session list or a screenshot of the period’s history, the mileage figures behind the share, and the bill page showing your tariff — the attachments let your employer re-run the sum in a minute. Keep the same layout monthly, so a change in the total reads as a change in driving, not in method. One honesty note belongs in the report itself: the charger’s kWh is a tracking figure, not a certified meter reading, and the mileage share is an estimate by construction. Labelled as such, both are a fair basis for an agreed reimbursement; presented as exact, they overclaim.
The Charger Behind the Report
The EV-ACS3210E is a 32 A Type 2 portable charger: single-phase at about 7 kW, current adjustable from 10 to 32 A, with app control and energy monitoring. The monitoring makes this report possible without a separate meter: every home session is recorded with its energy, ready to total at the period’s end. It is also OCPP-ready — what that wording does and does not promise is worth confirming in writing before an employer relies on it.
Frequently Asked Questions
My company car also charges at work and at public stations. Does the report cover those?
No — it covers home sessions only, because those are the cost you bore. Workplace and public charging sit on the operator’s or employer’s own records; keep the two streams separate.
Can the split just be a fixed amount per company mile?
It can, if your employer’s policy agrees one. The rate is the policy’s to set — there is no standard figure this article can give you, and any agreed rate belongs in the same written method as the split.
What if my employer queries the charger’s kWh figure?
Show the working: the session list, the tariff page, the share calculation. If the disagreement is about accuracy rather than arithmetic, the honest answer is in the report — a tracking estimate, with a certified meter the step up if required.
