Statistics for your EV charging
Every session from your charger, priced at the spot price of each quarter hour it charged in: what charging costs per car and month, what charging at the right time saved, and the carbon footprint.
What you see
- Cost per session
- Energy, cost and the average price per kWh of each session, priced per quarter hour with your markup, VAT and grid fees, or at your fixed price.
- Savings by timing
- What the same charging would have cost if it had started at plug-in, and so what waiting for the cheap hours saved.
- Per car and RFID tag
- Each session is matched to the car that was plugged in, each car in its own colour; a session can be corrected by hand.
- CO₂
- In the Swedish price areas: the carbon intensity of the grid in each hour you charged.
- Charging curve
- The power over each session, so you see when the car slowed down near full.
- Months and days
- A chart per month, or per day for one month, a table view, CSV export and a monthly report.
- Driving log
- With the car's login: trips, distance and kWh per 100 km.
Which chargers give their history
Zaptec and Easee give every session, imported every hour (Zaptec lists a session once the car is unplugged), and so do OCPP chargers, though OCPP is still being tried with real chargers. Charge Amps gives each session's totals. Wallbox sessions aren't imported yet.
Questions
- Does it count charging I start myself?
- Yes: every session the charger reports is imported, also those started with a tag or the charger's own app.
- Can I export it?
- Yes: the sessions as CSV, and everything stored about you as JSON.
- What if I pay a fixed price?
- Then each session is priced at it, also by time of day if your price changes over the day.
