The electric car lithium battery common failures and solutions

Source: 2020 - 04 - 19 20:53 hits: with the development of science and technology, improvement of living standards, we are becoming more and more convenient travel, transportation is multifarious also, car is the most common means of transportation. With the improvement of people environmental protection consciousness, the status of traditional fuel vehicle gradually under the threat of electric cars. Why electric cars so popular? Due to the electric car is the main source of power lithium batteries, so the electric car of the lithium battery is different from other types of lithium batteries. Lithium battery electric vehicle is common fault one, function in electric cars, electric car is the biggest effect of lithium-ion batteries for automotive power drive system. In hybrid cars equipped with the traditional engine, lithium batteries of electric cars is not only the main motor power, and auxiliary power. Under the different function of electric cars, electric cars, lithium battery plays a different role. For example, when the car in low speed running or a car has just started, the main power in the lithium battery electric vehicles to provide a car, and the auxiliary power lithium battery electric vehicle, when the car speeds up under full load, the electric car of the lithium battery energy storage if the car slow down or run normally. 2. Common failures and measures to eliminate electric car lithium-ion batteries common failures and troubleshooting measures of batteries in electric cars, in use process may arise due to improper operation, large and small fault, one of the most common is the lithium battery internal circuit of electric cars, chargers green light doesn't change, short range, etc. 1, when the case should be timely to maintenance of the battery, if long time don't start electric cars, electric cars, the lithium battery unused for a long time, charging should be timely maintenance, to keep the battery's health status. 2. Need to check on a regular basis. Lithium-ion batteries in electric cars in use for a long time, there will be some problems more or less. 3, the electric car lithium-ion batteries to avoid large current discharge, large current discharge on the properties of panels physical damage is very high. 4. Electric vehicle charging time for lithium battery charging. Charging time is too long will cause damage to the battery, affect the service life of the battery. 5, electric lithium batteries to prevent exposure to sunlight, high temperature damage to the battery is very big, the same method, also want to avoid charging plug fever. 3, protective measures electric car lithium-ion battery protection has a protective shell, shell protection is in order to avoid the damage of the electric car battery in use process, the diaphragm block protection, diaphragm block protection is to prevent the damage caused by internal lithium-ion batteries of electric cars, such as when the battery temperature is too high, the diaphragm will automatically block, the battery does not work, in order to avoid damage, charging pressure protection, not only can stop the air, also can prevent the lithium ion leakage. Therefore, lithium-ion batteries in electric cars, set voltage limit and overcharge protection is very necessary. In order to the service life of the battery and battery safety, must attach great importance to the protection of lithium battery electric cars these measures. To sum up, the lithium battery as the main power sources of electric vehicles, travel for us to provide the strong power, but when use must pay attention to the protection of the battery. The characteristics of the advantages of lithium battery lithium battery pack 1. The service life of lithium-ion battery pack in about 2000 times or more, so in normal circumstances, the lithium battery pack 7 - may be used For eight years. 2. In general, lithium-ion battery pack will not explode, so very safe to use. 3. Lithium battery, speed, high temperature resistance. 4, large capacity and lithium battery pack is a big advantage, but also the memory effect, can use when you charge, don't have to wait for recharging the battery discharge. 5. Non-toxic pollution-free aluminum battery to use environmental protection very much. 6. China's reserves are abundant raw materials lithium-ion battery pack, don't need to rely on foreign imports, so the cost is lower than other batteries will be many, price is also high.
