Power lithium battery it is an important energy device of modern electric vehicles. Its performance and service life directly affect the mileage and service life of electric vehicles. In order to ensure the normal operation of power lithium battery and prolong its service life, daily maintenance and regular overhaul are essential. This article will introduce the daily maintenance and overhaul methods of power lithium battery to help car owners effectively manage and maintain the power system of electric vehicles.

First of all, daily maintenance is the basis to ensure the normal operation of power lithium batteries. In daily use, car owners should pay attention to the following points:

1. temperature control: power lithium battery is sensitive to temperature, too high or too low temperature will affect battery performance and life. Car owners should try their best to avoid using electric vehicles in extreme temperatures, especially in high temperature environments. At the same time, in cold weather, car owners should preheat the electric vehicle in advance to ensure that the battery works within a suitable temperature range.

2. Charging Management: The correct charging method can prolong the life of the power lithium battery. Car owners should use the original charger or certified charging equipment for charging to avoid using inferior chargers. In addition, avoiding frequent charging and overcharging is also an important measure to protect the battery.

3. Prevent over-discharge: excessive discharge will damage the performance and life of power lithium battery. Car owners should arrange mileage reasonably according to the usage of electric vehicles to avoid continued use when the battery power is too low. When the battery power is too low, charge it in time to avoid excessive discharge.

Secondly, regular maintenance is an important link to ensure the long-term stable operation of power lithium batteries. Car owners can perform maintenance according to the following steps:

2. Cleaning and maintenance: regularly clean the dust and dirt on the surface of the battery, you can use a clean wet cloth to wipe. Avoid using chemical solvents or excessively moist cloth to avoid damaging the battery.

3. Capacity Testing: use professional battery capacity testing instruments to conduct regular capacity testing on batteries. According to the test results, judge the health status and remaining capacity of the battery, adjust the use strategy or replace the battery in time.

4. Cyclic charge and discharge: periodic cyclic charge and discharge can activate battery active substances and prolong battery life. Car owners can charge and discharge operations in a safe environment according to the requirements of the battery user manual.

5. Regular maintenance: regular maintenance and maintenance of the battery according to the requirements of the battery user manual. This includes cleaning the battery connector, checking the battery cooling system, replacing the battery liquid, etc.

The daily maintenance and overhaul of power lithium batteries are crucial to the normal operation of electric vehicles and the extension of battery life. Car owners should follow the correct charging management and usage methods, and regularly carry out the appearance inspection, cleaning and maintenance, capacity detection and cyclic charging and discharging of the battery. Through scientific maintenance and overhaul, we can maximize the performance of power lithium batteries and provide reliable power support for the travel of electric vehicles.
