With the popularity of new energy vehicles and the increase of owners' favor for new energy vehicles, the advantages of saving money, green and environmental protection have made many people incorporate new energy vehicles into their shopping lists; But pure electric vehicle charging is an inescapable topic.

Many people for the new energy vehicle charging need to be full every time, must reach 100% or charge with use is better, when should charge?

At present, the three most common types of batteries for new energy vehicles are mainly: ternary lithium batteries, lithium iron phosphate batteries and lithium nickel metal hydride batteries. Among them, ternary lithium batteries and lithium iron phosphate batteries have high energy density and relatively stable performance, and these two types of batteries are the most widely used in electric vehicles. The nickel-metal hydride battery is also a good performance battery, which is gradually used in the field of new energy vehicles.

Lithium iron phosphate battery has good thermal stability, safety, low cost, long life, low energy density, fear of low temperature. When the battery temperature is 500-600 ° C, its internal chemical composition begins to decompose, and puncture, short circuit, high temperature will not burn or explode, and the service life is longer. However, the vehicle mileage is generally, when the temperature is lower than -5 ° C, the charging efficiency is low, and it is not suitable for the demand of charging in the north in winter.

Ternary lithium-ion battery has high energy density, long cycle life and is not afraid of low temperature; Insufficient stability at high temperatures. The energy density can reach the highest, but the high temperature is relatively poor, and pure electric vehicles with requirements for driving range are in the mainstream direction, and are suitable for northern weather, and the battery is more stable at low temperatures.
