Preventive, predictive and software maintenance
Modern EVs predict faults and fix many problems with over-the-air updates.
You'll learn
- Understand preventive, predictive and software maintenance
- Know which checks an owner can do and which need a professional
- Recognise warning signs early
Overview
Preventive maintenance follows a schedule. Predictive maintenance uses sensor data to flag problems before they happen. Software maintenance updates the car's control systems.
In depth
The battery management system tracks cell voltages, temperatures and insulation. Many cars alert the owner or service centre when values drift.
Over-the-air updates can improve charging speed, range estimation, heat-pump control and fix faults without a workshop visit.
Install updates
Keep the car on the latest software. Many 'faults' are fixed by an update.
Key takeaways
Remember this
- Preventive = schedule; predictive = data.
- The car monitors itself constantly.
- Software updates are real maintenance.
