Effectively maintain electric vehicle lithium batteries!
According to relevant sources, among numerous complaints about the quality of electric vehicles, battery problems account for over 80%, as the lifespan of electric vehicle batteries directly determines the driving range of electric vehicles. So what should be paid attention to in the maintenance of lithium batteries for electric vehicles? Which electric vehicle battery is good? Today, we would like to invite technicians from Lumingda Company to explain how to maintain lithium-ion batteries for electric vehicles.
1. Regularly check
In the process of using electric vehicles, if we find that the driving range of the electric vehicle suddenly decreases in a short period of time, it can be concluded that it is due to short circuit phenomena such as battery breakage, electrode softening, and electrode active material detachment in the lithium battery. At this point, it is necessary to go to a professional organization for inspection or to the lithium battery wholesale market for reassembly. This can relatively extend the lifespan of the battery pack. At the same time, the price of lithium batteries is also cheap.
2. Prevent power loss during storage
Low battery state refers to the situation where the battery is not charged in a timely manner after use. This can easily block the ion channel, causing insufficient charging and a decrease in battery capacity. The longer the time, the more severe the battery damage.
3. Correctly grasp the charging time
Under the guidance of technical personnel, accurately grasp the charging time according to the actual situation, refer to the usual usage frequency and driving mileage, and also pay attention to the capacity size description provided by the lithium battery brand manufacturer, as well as the performance of the supporting charger, the size of the charging current and other parameters to grasp the charging frequency. The average charging time is around 8 hours. It is best to charge the battery once when the discharge depth is 50% -80%.
4. Prevent exposure to sunlight in high temperature environments
Electric vehicle batteries are exposed to high temperatures. If the temperature is too high, the internal pressure of the lithium battery will increase, forcing the battery pressure limiting valve to automatically open. This will cause the lithium battery to lose water, leading to a decrease in battery activity, accelerated plate softening, and ultimately fatal damage after charging.
