Maximise your EV’s battery life with seasonal maintenance tips for year‑round reliability.
Electric vehicles are changing the way we drive, but their batteries are sensitive to temperature. Knowing how to care for your EV through seasonal changes helps maintain range and longevity.
Optimal Temperature Range
EV batteries operate most efficiently between about 20 °C and 30 °C. Hot or cold conditions reduce performance. In winter, range can drop by 25 % on average, and tests have found reductions as high as 39 %. In summer, extreme heat can also degrade battery health over time.
Seasonal Maintenance
During spring and autumn, prepare for upcoming temperature swings. Have your charging system inspected, ensure cabin and battery heating systems are functioning and check tyre tread depth. When winter approaches, pre‑condition your vehicle while plugged in to warm the battery and cabin before you drive, park indoors if possible and use heated seats instead of full cabin heat.
Charging Habits
Keep your battery charge between about 20 % and 80 % to prolong its life. Avoid frequent fast charging unless necessary, as it generates more heat. In cold weather, charge immediately after driving so the battery is still warm.
By adapting your habits to the seasons, you’ll get the most from your EV year‑round. For expert EV servicing in the GTA, join the Karmeka wait‑list and connect with specialists who understand electric technology.
