4 Simple Tips to Maximize Your EV Battery Life

Protect Your Battery from Extreme Heat

High temperatures can stress your EV battery, especially when parked. The thermal management system cools the battery if you leave your car in the sun. This process drains power and can cause long-term damage. To avoid this, park in the shade or a garage whenever possible. If you can access a charger, plug it in while parked so the cooling system runs off-grid power instead of your battery. Keeping your EV cool helps maintain its efficiency and longevity.  

Avoid Keeping the Battery at 100% Charge  

Your Kia EV has a built-in battery management system to prevent extreme charge levels. However, consistently charging 100% can still wear out the battery over time. Aim to keep the battery level between 20% and 80% for daily driving. This reduces strain and extends the overall lifespan. While a full charge is acceptable for long trips, it is best to avoid it for everyday use.

Limit Fast Charging When Possible  

Fast charging is convenient, especially on road trips. However, it pushes a high amount of current into the battery, causing extra heat and wear. Whenever possible, use standard Level 2 charging at home or public stations. Over time, slow and steady charging helps preserve battery capacity. Studies show that eight years of standard charging can result in 10% longer battery life than frequent fast charging.  

Store Your EV With the Right Charge Level  

If you plan to park your EV for an extended time, avoid leaving it with a full or empty battery. Both extremes can speed up battery degradation. A good rule of thumb is to keep the charge level between 25% and 75% when storing your EV. A timed charger can also help maintain this range and prevent unnecessary battery stress.
