The fast charging debate is always interesting to watch, because the charger itself often gets blamed for things that are simply basic battery physics.
Batteries generate heat during charging regardless of speed. It’s not a “fast charging phenomenon” it’s a result of current flow and internal resistance.
What actually matters for long-term battery health is not whether heat exists, but how excessive and how sustained it becomes. Modern EVs with active thermal management are specifically engineered around this reality.
I’d be genuinely interested to hear from high-mileage owners or drivers heavily relying on DC fast charging. Real-world data tends to be far more useful than general internet assumptions.
