Avoid Charging in Direct Sunlight

Charging under direct sunlight can cause your battery to overheat. Always park and charge your EV in a shaded area or garage. This reduces thermal stress on the battery cells.

Use Scheduled Charging at Cooler Times

Set your EV to charge during the early morning or late evening when temperatures are lower. This helps keep the battery cooler and improves energy efficiency. Timed charging also balances grid demand.

Pre-Cool Your Cabin While Plugged In

Use your EV's pre-conditioning feature to cool the cabin while the car is still charging. This avoids using battery power for cooling once you start driving. It’s a smart way to conserve range.

Avoid Fast Charging Frequently

Frequent use of DC fast chargers in summer can heat up the battery. Whenever possible, use slower AC chargers to extend battery life. Save fast charging for emergencies or long trips.

Maintain Optimal Tyre Pressure

Hot weather affects tyre pressure, which in turn impacts EV efficiency. Check and adjust tyre pressure regularly to reduce battery strain. Proper tyres reduce rolling resistance and preserve range.

Don’t Let Battery Drain Too Low

Extreme heat plus low battery levels can damage battery health. Try to keep charge levels between 20% and 80%. Avoid deep discharges unless necessary.

Park in Shaded or Covered Spaces

Minimise exposure to direct sunlight by using covered parking. This keeps the interior and battery cooler. If no shade is available, consider using sunshades or car covers.

Monitor Battery Temperature on the App

Use your EV’s companion app to track battery temperature. Alerts or diagnostics can help you take action before overheating becomes a problem. Proactive monitoring increases battery safety.

Avoid Heavy Acceleration in Hot Weather

Aggressive driving generates more heat and uses more energy. Drive smoothly and gradually accelerate to avoid excess battery strain. It helps maintain battery temperature within safe limits.
