What is Tesla's 8-Year Battery Replacement Policy?
1 Answers
Tesla's 8-year battery replacement policy is primarily in accordance with national regulations, which stipulate that electric vehicles provide an 8-year or 150,000-kilometer warranty for the battery. During the warranty period, the battery's degradation should not exceed 30%, so there's no need to worry about battery lifespan within this timeframe. Regarding the maintenance of electric vehicle batteries: 1. Timely Charging: It is essential to charge the battery promptly when it is about to run out of power. Generally, when the fuel gauge light comes on in a conventional car, there are still about 10 liters of fuel left in the tank, allowing the driver to immediately refuel at a gas station. However, if an electric vehicle's battery is not charged in time when depleted, the sulfuric acid in the battery can oxidize when the battery is undercharged, leading to insufficient charging and, over time, a reduction in battery capacity. 2. Control Charging Time: Since charging an electric vehicle takes a relatively long time—approximately 8 hours or even longer—many owners tend to leave their vehicles charging continuously until fully charged. However, too much of a good thing can be harmful. Overcharging an electric vehicle's battery can cause it to overheat, affecting its lifespan. Therefore, it's important to manage the charging time and unplug the charger once the battery is fully charged. 3. Charger Maintenance: Ensure the charger is well-ventilated and keep it away from water. Otherwise, it may affect the charger's lifespan and even damage the battery during charging.
