Is fast charging recommended for electric vehicles?

There are different types of lithium-ion batteries for electric vehicles. Generally, there are two types of lithium iron phosphate batteries and ternary lithium-ion batteries. The former is suitable for slow charging and the latter is suitable for fast charging. It depends on the manufacturer’s charging strategy for lithium-ion batteries. It will be set inside the charger and cannot be changed. Each lithium-ion battery manufacturer will configure a slow charging port and a fast charging port according to the characteristics of the lithium-ion battery, and the BMS system will uniformly manage the charging process. As long as it is charged according to the manufacturer's requirements, it is safe. Under normal circumstances, lithium-ion batteries in electric vehicles cannot be used for fast charging outside. Under normal circumstances, it will not match fast charging, unless the charging station has an adaptation standard for fast charging of related models. These fast charging protocol standards are usually set by the electric vehicle manufacturer at the factory, and the agreement is used to verify whether the charging source complies with the lithium battery. Charging standard. At present, in most cases, only the original charging station can use fast charging. Of course, there are also charging stations that can also be adapted to fast charging. But very few. Fast charging of lithium-ion batteries for electric vehicles saves charging time while also having a certain impact on the lithium-ion batteries themselves. Lithium batteries are actually not suitable for fast charging, and fast charging will accelerate the polarization of lithium batteries, thereby affecting battery performance. Due to the polarization phenomenon in the battery, the maximum charge current that it can accept will decrease with the increase of charge and discharge cycles. Lithium-ion battery manufacturers analyze and believe that a series of problems such as the reaction decomposition of electrolyte and gas production have suddenly increased the risk factor, which will affect the safety of lithium-ion batteries.
