Function and principle of protective plate for lithium iron phosphate battery pack of electric vehicle. In recent years, electric vehicles have gradually developed, and lithium batteries have low discharge and no memory effect. Because the protective plate is added to the lithium battery in the production process of lithium iron phosphate battery, the lithium battery can be overcharged and discharged. The lithium battery itself has a high power tolerance, and the lithium battery pack selected for electric vehicles can reach the high-efficiency capacity of 15-30C, so as to accelerate the high-intensity start-up on the vehicle.
B generally adopts distributed architecture design, which consists of a master device and multiple slave devices. Is it necessary to use protective plate for lithium iron phosphate battery of electric vehicle?
The application of lithium batteries is more and more extensive, so people pay more and more attention to the safety of lithium batteries in electric vehicles, and the lithium battery protection board becomes important. We all know the function of the protection board of lithium battery pack, and the most basic three points are: preventing overcharge, preventing overdischarge and preventing the harm caused by short circuit.
Therefore, lithium iron phosphate battery electric vehicles will use protective plates. If it is found that the temperature of the battery itself rises during the use of the lithium battery for electric vehicles, it is likely to be caused by a short circuit between the positive and negative electrodes. If there is a lithium battery protection plate, if the positive and negative electrodes are short-circuited, the protection plate will understand that the power is cut off, so it will not generate heat. On the contrary, if there is no lithium battery protection plate, the battery will be abnormally hot.
