For operators where paying a flat fee unlocks a lower price per kWh. Log the fee here so it counts toward your real total cost — the discounted price itself just goes in the normal "price per kWh" field on each session.
It renews automatically each period from the start date until you end it — the cost adds itself up as time passes. Ending it sets the end date to the close of whatever period is currently running.

Tyre changes, tyre storage, repairs, inspections — anything you spend on keeping the car running.

Works like a flat-rate plan: it renews automatically each period until you end it. Comprehensive (havarijní) cover is optional — track it only for whatever stretch of time you actually had it.

Recorded with and without VAT since which one counts depends on whether the vehicle is owned privately or through a company — set that in Settings.
Charts couldn't load — this needs a small library from the internet, and it looks like it's blocked or unreachable on this network. Everything else in the app works normally; try again later or on a different network.
Consumption is a vehicle average kept here. Fuel prices are entered per session (since they move around) — the values below are just the starting default for new sessions.
Charging and flat-rate plans always count. Choose whether service and insurance costs count too.
A flat-rate plan is often what unlocks the lower price per kWh in the first place — include it here to compare against your real, all-in charging cost.
Every account and database is saved to the cloud as soon as you enter or change anything — log in from any device and your data is there.
ChargeR is free to use. If it's saving you time or money, you can help keep it running and improving with a small contribution — entirely optional.
A manual, one-time snapshot of this database, exported to one .xlsx file — handy to keep an offline copy.
Import legacy data
One-time import from an older chargelog-data.json backup file (from before accounts moved to the cloud). Only imports the vehicle(s) whose saved email matches your current account.
This clears every session currently loaded in the app. Export a backup first if you might want it back.
Delete this database
Permanently deletes this vehicle database — its sessions, tariffs, service records, insurance and purchase price. Your account and any other databases are unaffected. This cannot be undone.
Delete your account
Permanently deletes your account and every database, session, tariff, service record, insurance policy and purchase record tied to it. This cannot be undone — export a backup first if you want to keep a copy.
Pick the date this plan actually ended — periods are counted up to and including this date, regardless of when you happen to enter it.
