How Long Does an Electric Vehicle Battery Last Before Replacement?
1 Answers
Generally, a battery can last 1-2 years under normal conditions. Situations that indicate the need for battery replacement include the battery charging quickly but depleting rapidly, or if it has been in use for over three years. Specific scenarios for battery replacement are as follows: Battery charges quickly but depletes rapidly: Normally, it takes about 8 hours to fully charge the battery. If it suddenly charges in just one or two hours, or even within a few dozen minutes, and then runs out of power after traveling a short distance, the following two reasons may be the cause: First, a small battery within the battery pack may have malfunctioned. Since individual small batteries are difficult to repair, the entire battery pack may need to be discarded. Second, the battery capacity may have shrunk, and its ability to hold a charge may be almost completely lost. At this point, the electric vehicle battery is essentially unusable. Use for over three years: The capacity degradation of lead-acid batteries is largely irreversible. After three years, the components of the battery will generally have deteriorated, and this deterioration tends to accelerate over time, quickly leading to a complete loss of charging and discharging capabilities. Some electric vehicle users may attempt to repair the battery. If the battery still cannot hold a charge after repair, this indicates that the battery is no longer functional.
