Electric vehicle lithium-ion battery capacity discharge process and relevant experience in charging and discharging

Electric vehicle lithium-ion battery capacity discharge process 1. In the initial stage, the terminal voltage of the electric vehicle lithium-ion battery drops rapidly. The greater the discharge rate, the faster the voltage drops; 2. The voltage of the electric vehicle lithium-ion battery enters a stage of slow changes. A period of time is called the platform area of u200bu200bthe battery. The smaller the discharge rate, the longer the duration of the platform area, the higher the platform voltage, and the slower the voltage drop. In the actual use of lithium-ion batteries, it is desirable that the lithium-ion batteries work in the platform area as much as possible; third, when the lithium-ion battery is nearly discharged, the load voltage of the lithium-ion battery begins to drop sharply until it reaches the discharge cut-off voltage. From the results of the capacity test, the curve relationship between the discharge current and the capacity can also be obtained at the same time. The relationship between different discharge current and capacity of lithium-ion batteries for electric vehicles, and the size of the discharge current of lithium-ion batteries will directly affect the actual capacity of the battery. The greater the discharge current, the corresponding reduction in battery capacity, which indicates that the greater the discharge current, the shorter the time to reach the termination voltage. So when talking about battery capacity, you should specify its discharge current (discharge rate). Relevant experience in charging and discharging lithium-ion batteries for electric vehicles Judging from the author’s experience in using electric vehicles for many years, the most important tips on the charging and discharging of lithium-ion batteries in electric vehicles are 1. Follow the instructions on the lithium-ion batteries for electric vehicles. Standard time and procedure for charging, even if it is the first few times, you must do so; 2. When the electric vehicle finds that the battery is too low, you should try to start charging the lithium-ion battery of the electric vehicle in time; 3. According to the lithium-ion battery of the electric vehicle Experts in the wholesale market analyze that the activation of lithium-ion batteries does not require special methods. Li-ion batteries will naturally activate during normal use of electric vehicles. If you insist on saying that the first time you use it for 12 hours, it is actually not scientific. 4. Be sure to use a suitable lithium-ion battery charger to charge, first insert the charger output plug into the battery charging socket, and then insert the charger plug into the mains socket, and observe the indicator light for charging judgment. If the charger is lost or damaged, please buy it from the corresponding dealer. Do not use lead-acid chargers or other forms of chargers for charging. 5. Partial discharge of lithium-ion batteries for electric vehicles is required, over-discharge is not appropriate, and frequent complete discharges should be prevented. Over-discharge may bring catastrophic consequences to the battery, especially high-current over-discharge, or repeated over-discharge has a great impact on the battery. 6. Long-term overcharge and overdischarge will cause serious damage and damage to the performance of the lithium-ion battery, and the serious will lead to extreme conditions such as explosion, so the battery is fully charged, if it has been plugged in the charger, sooner or later It will lead to tragedy.
