   A 2021 Tesla Model 3 Standard Plus used for Uber service has demonstrated exceptional battery performance. Its LFP (Lithium Iron Phosphate) battery maintains 88-90% State of Health after 400,000 km of driving. 

   This data was revealed during diagnostics by Australian EV specialist EV Workz.

1. Exceptional Battery Performance Data

The vehicle's data shows impressive statistics:

Metric Value
Total Energy Driven 49,928 kWh
DC Fast Charging 15,556 kWh (29%)
AC Charging 38,012 kWh (71%)
Battery State of Health 88-90%

2. Charging Patterns and Durability

   The battery endured significant fast charging usage. Despite 29% DC fast charging, it maintained excellent health. This demonstrates LFP battery's resilience compared to traditional lithium-ion batteries.

   Research indicates frequent DC fast charging may accelerate aging. However, LFP chemistry shows superior durability in real-world conditions.

3. Maintenance and Reliability

   The vehicle required service for acceleration vibration. Diagnosis revealed only motor mount wear - not major component failure.

Repair costs were minimal:

  • A$130 in parts
  • 7 labor hours
  • Total cost under A$500

   Forum discussions suggest LFP batteries can last over 600,000 km. Battery replacement cost is approximately A$16,000.

   This translates to only A$0.02 per km in battery degradation costs. Significantly lower than gasoline vehicle maintenance.

4. LFP Battery Advantages

LFP batteries offer several advantages:

  • Higher thermal stability
  • Lower production costs
  • Cobalt-free chemistry
  • Better cycle life
  • Superior safety characteristics

These features make LFP ideal for high-usage applications like ride-sharing services.

5. Identifying LFP Battery Models

Since Q4 2021, most standard-range RWD Model 3 and Model Y vehicles use LFP batteries.

Check your battery type:

  • Go to Controls > Software
  • Select Additional Vehicle Information
  • Look for "Lithium Iron Phosphate (LFP) battery"

   If it says "Lithium-ion battery", you have an NMC battery

   Tesla's Nevada LFP factory is nearing completion. It will initially produce batteries for Megapack and Powerwall. Future affordable Tesla models may use these batteries.
