About
This site exists because most information about Chinese electric cars in English is written by people who borrowed one for a week.
Who writes it
Written by Marcelo Saldaña, a systems engineer who has driven a BYD Atto 3 as a daily car since 2024.
As of the most recent log entry the car has covered 49,351.3 km at a lifetime average of 15.6 kWh/100 km. That figure comes off the car's own display and is updated monthly.
Something you should know up front
The car is in Chile. The prices on this site are British.
That combination deserves an explanation rather than a quiet omission. The Atto 3 sold in the United Kingdom and the BYD Yuan Plus sold in Chile share the same 60.48 kWh LFP (BYD Blade) battery, 150 kW motor and 4,455 / 1,875 / 1,615 mm body, figures BYD UK and BYD Chile both publish, so consumption is treated as transferable. Charging behaviour does not: the Chilean car carries a 7 kW onboard charger and an 80 kW DC module verified (BYD Chile ficha técnica Yuan Plus 2026.07), where the UK car has 11 kW and 88 kW. Every charging figure on this site is therefore the UK car's, from BYD's own UK publications, never from the owner's sessions. Electricity prices, charging networks and weather do not transfer either, which is why every price on this site is sourced from a named British supplier or from Ofgem, and never from personal experience.
Where a figure comes from the car, it is owner data. Where it comes from the market, it is cited. The two are never mixed. The method page explains how each figure is derived and labelled.
What is actually logged
Four records, kept continuously rather than assembled for an article:
- Every charging session: energy at the meter, cost, network, temperature
- Sampled journeys, including one fixed reference route meant to be driven weekly (3 days logged so far)
- A monthly snapshot of odometer and lifetime consumption
- A battery capacity check every two months, to the same protocol each time (none logged yet)
The reference route matters more than it sounds. Because the route never changes, temperature is the only variable, which over a year produces a real consumption curve for this car rather than a manufacturer's laboratory figure.
How this site makes money
It is built to carry display advertising, but none is served yet and it earns nothing today. When advertising starts, advertisers will have no influence over what is written, and no manufacturer or charging network has paid for or reviewed anything here. Where affiliate links are used they will be marked as such before the link, not after.

Corrections and questions: hello@evfieldnotes.com
If a number here is wrong, say so. It gets fixed and the correction is noted on the page.
Corrected 2026-09-13. This page previously said the car in Chile and the UK Atto 3 were the same vehicle, so that consumption, charging behaviour and battery degradation transfer directly. BYD Chile's datasheet gives the Chilean car a 7 kW onboard charger and an 80 kW DC module, against the UK car's 11 kW and 88 kW. Charging behaviour does not transfer, and the page now says so. Consumption does.
Corrected 2026-10-01. This page said the site makes money from display advertising; none has been served, and the sentence now follows whether the build carries an advertising account. It said the reference route is driven weekly; the log shows 3 days so far, and the page now shows that count. And it said the Chilean and UK cars share the same motor, battery and body with a UK source for the battery only; the motor and the dimensions have been added to the UK record from BYD's UK launch release and to the Chilean record from the owner's manual, and the sentence is now built from the rows both records publish.
