Best practices for maintaining EV batteries in hot climates:
-
Optimize charging habits
- Limit charge to 80% instead of full capacity to reduce heat and internal resistance.
- Avoid charging during peak heat by scheduling sessions for cooler morning/evening hours.
- Skip frequent fast charging, as rapid charging generates excessive heat that accelerates battery degradation.
-
Thermal management strategies
- Pre-cool while plugged in using timers or apps to preserve battery charge.
- Park in shade/garages to minimize exposure to direct sunlight.
- Use battery saver modes if available, which optimize temperature regulation.
-
Driving efficiency
- Maintain proper tire pressure to reduce rolling resistance and improve range.
- Minimize A/C usage by using seat coolers, window ventilation, or pre-cooling.
- Shed unnecessary weight to decrease energy demands on the battery.
-
Longevity protection
- Follow manufacturer guidelines for charge limits and cooling system maintenance.
- Monitor range adjustments – expect up to 31% reduction at 100°F (37.8°C) and plan routes accordingly.
- Avoid extreme temperatures – lithium-ion batteries degrade fastest above 104°F (40°C).
-
Proactive maintenance
- Keep software updated to ensure optimal thermal management performance.
- Clean battery vents to prevent airflow obstruction in cooling systems.
- Schedule battery health checks with EV service centers before extreme weather seasons.
