Battery degradation in hot climates is a key concern for EV importers. Buyers can reduce this risk through careful model selection, specification checks, and post-purchase best practices.
Pre-import selection:
- Choose the right battery chemistry: Lithium iron phosphate (LFP) batteries generally handle high temperatures better and have longer cycle life than ternary lithium (NMC) batteries. Many Chinese EV models now offer LFP options (e.g., BYD Blade Battery).
- Check thermal management system: Ensure the EV has active liquid cooling (not just air cooling) for the battery pack. Active cooling maintains optimal temperature range even in extreme heat.
- Look for battery preconditioning features: Some models allow pre-cooling the battery via app before driving, which reduces initial heat stress.
Import and storage best practices:
- State of charge (SoC) during shipping: Request that the battery be shipped at around 30–50% SoC, as high SoC (>80%) accelerates degradation when combined with high storage temperature.
- Avoid long-term storage in direct sun: Once landed, store EVs in shaded or covered areas until sold. High parking temperatures accelerate calendar aging.
- Educate end customers: Advise them to park in shade, use scheduled charging (avoid charging immediately after a long drive in heat), and keep SoC between 20-80% for daily use.
