Electric Car Battery Care: What to Avoid to Preserve Range

The battery is the heart of an electric vehicle. Preserving it means ensuring range, performance, and resale value in the long run. And yes — the type of charging you choose makes a big difference.

🔋 How Does an EV Battery Work?

Lithium batteries used in electric cars have a life cycle defined by full charge cycles. The more demanding the charging process, the greater the long-term wear.

⚠️ Fast Charging (DC or 22kW): More Convenient, Less Healthy

Fast charging (like DC or 22kW wallboxes) is useful for travel, but:

• Heats up the battery more, accelerating degradation
• Reduces long-term efficiency of total capacity
• Can shorten battery life if used frequently

Manufacturers like Tesla, Renault, and Hyundai recommend limiting fast charging to when it's truly necessary.

✅ Slow Charging (AC up to 3.5kW): Best for Battery Longevity

The 16A (3.5kW) portable charger provides a consistent and gentle charge — ideal for battery health.

• Prevents temperature spikes
• Preserves total charge capacity over the years
• Perfect for daily use (overnight charging)

🧠 Tips to Maximize Battery Life

• Avoid charging to 100% all the time (80–90% is ideal)
• Avoid discharging to 0% — keep it above 20%
• Use slow charging whenever possible (like the 16A option)
• Avoid charging in extreme heat

📊 What Do Studies Say?

International studies show that vehicles regularly charged with more than 11kW lose up to 10–15% more capacity after 5 years compared to those charged under 4kW.

🚀 Conclusion

If you want to keep your EV battery healthy and avoid range issues, the best strategy is to charge at home with a 16A portable charger. It’s smooth, safe, and protects your investment.
