To claim home charging costs, you need a record of energy used per session or per month and the electricity rate you paid. A connected charger such as the EV-ACS3210E records energy per session and provides monthly usage reports in its app. Combine those kWh figures with the unit rate on your electricity bill, and keep both together. If your employer needs a file rather than screenshots, check which export options the app offers.
Key Takeaways
- Combine kWh from the app with the rate on your bill.
- Keep records consistent and by period.
- Check whether your employer needs certified metering.
What an Expense Record Should Show
Employers and accountants generally want evidence that is clear, consistent and linked to the company car or business mileage. Policies differ, so check yours first.
| Item | Where it comes from | Why it matters |
|---|---|---|
| Date and time of each session | Charger app session list | Links charging to work periods |
| Energy delivered in kWh | Charger app, per session or monthly | The quantity you are claiming |
| Electricity unit rate | Your electricity bill or tariff | Converts kWh to cost |
| Off-peak or peak rate split | Bill or tariff details | Time-of-use plans have several rates |
| Vehicle | Registration or fleet number | Shows which car was charged |
| Total claimed | Your calculation | kWh times rate, by period |
Getting the Data Out of the App
- Open the session history and check that dates and kWh are complete for the claim period.
- Use the monthly usage report for a simple total if your employer accepts monthly claims.
- If a direct export is available, save it in the format your finance team prefers.
- If not, take dated screenshots of the monthly report and keep them with the matching bill.
- Note any sessions for a private car or personal trips and exclude them as your policy requires.
Our guide on smart charger meters explains how chargers measure energy, and how many kWh it takes to charge an EV helps you sense-check the numbers.
A Worked Example
Suppose the app shows 210 kWh charged in a month, and your tariff is 0.30 per kWh in your currency. The claim is 210 times 0.30, or 63. If you are on a time-of-use plan and most sessions ran off-peak, apply the off-peak rate to those sessions. Keep the calculation simple and repeatable each month.
When You Need Certified Metering
Some employers or tax rules require a certified meter rather than the charger’s own readings. A charger’s built-in measurement is useful for tracking but may not be accepted as billing-grade evidence everywhere. Ask your employer or a tax adviser what evidence is required where you live. For workplace and fleet setups, a managed OCPP platform can centralise records; read OCPP explained.
The EV-ACS3210E is a Type 2 portable charger with app control, real-time energy monitoring, monthly usage reports, OCPP readiness, adjustable current from 10 A to 32 A, an IP65 rating and a 7.5 m cable.
Frequently Asked Questions
Can I claim home EV charging from my employer?
Many employers allow it under their expense policy. You usually need kWh records and your electricity rate.
Is the charger’s energy reading accurate enough for expenses?
It is often accepted for internal claims, but some employers or tax rules need a certified meter. Check first.
What if my app cannot export data?
Keep dated screenshots of monthly reports with the matching electricity bill.
