Honest, jargon-light writing on EV battery health, ECU coding, software updates and the electronics quietly running your car. Written by the engineers who do the work.
State of health, cell balance, capacity fade — the numbers on a battery report can look intimidating. Here's how to read one properly, what's normal for the age and mileage, and the figures that should give you pause before you buy.
Practical, evidence-led pieces — the same thinking we apply on the ramp, written down.
Diagnostics
A P0A80 doesn't mean "replace the battery". It means "look here". The difference between reading a code and diagnosing a car.
Fit a new module and it often won't work until it's coded to the car. Here's what coding does — and why software now matters as much as spanners.
From a tired on-board charger to a corroded charge port and the odd firmware bug — the usual suspects behind a sluggish charge.
Software
Manufacturers quietly release software that improves range, smooths drivability and squashes bugs. Most owners never get it applied.
Modern cars hide cameras behind the screen. Replace it without recalibrating ADAS and lane-keep and emergency braking can read the road wrong.
Auto-Electrical
The fault that never happens when the car's in the bay. The tools and patience it takes to catch a gremlin in the act.
