DC fast charging vs. AC slow charging:
- DC fast charging: Ideal for quick top-ups during long trips. Adds significant range in minutes, but generates more heat and can stress the battery if used too frequently.
- AC slow charging: Gentler on the battery, ideal for daily use like overnight home charging. Helps maximize long-term battery health.
- Battery longevity: Regular use of AC charging is generally better for preserving battery capacity over time.
- Convenience trade-off: DC fast charging is convenient when you're short on time; AC is more cost-effective and suitable for routine charging.
For most EV owners, a mix of both is best — AC for regular charging and DC for road trips or emergencies.
