Generally speaking, ternary lithium battery packs are for Electric Car. This type of battery pack has a cycle life of more than 1,200 times. Taking the annual charging times of an Electric Sedan Car as 150 times as an example, if converted, it means that the life of the battery pack can reach at least eight years, which means that car owners do not need to replace the battery pack within eight years. However, eight years is just an ideal guess. Depending on the car owner's driving habits and daily use environment, the lifespan of the ternary lithium battery pack will also vary. And when the battery's cycle life exceeds 1,200 times, the capacity of the entire battery pack will drop to less than 80% of the original, and the vehicle's endurance will be much worse than before.
1. Observe whether the charging time and charging capacity of the Electric Sedan Car are significantly reduced.
2. Whether the pure electric cruising range is significantly reduced.
3. You can determine whether the battery of the Electric Sedan Car needs to be replaced through the after-sales service point. Use the OBD diagnostic instrument to conduct routine testing of the power battery, and perform repairs or computer data correction according to the errors prompted. By fully discharging the vehicle's power battery 1-2 times (discharge until the remaining power of the power battery is only about 5% of the critical value displayed on the instrument panel, and then fully charging it again), use professional instruments to record the data, and the data results A unified summary will be fed back to the manufacturer, and the manufacturer's technical staff will determine whether the battery replacement conditions are met. If the conditions are met, the battery factory will be approved to send a new battery to the dealer for replacement. If the conditions are not met, the corresponding solution will be fed back.
