When our electric cars are out of power, we think of charging. In fact, we don't know the charging methods of electric cars very well. Let's talk about the three common charging methods of electric cars by our Linyi electric car manufacturer.

Constant current charging means that the current is constant during the charging process. If multiple batteries are connected in series, this charging method is generally selected. The current in the charging process is very small, so the charging time is longer. This method is generally used in our family.

      Constant voltage charging refers to the amount by which the voltage remains constant during the charging process. At the beginning of charging, the battery resistance is very small and the charging current is very large. After charging for a period of time, the internal resistance of the battery increases, and the charging current becomes smaller in the later stage of charging. This charging method is relatively fast.

fast charging, this charging method allows electric vehicles to quickly complete charging. In a short period of time, this method can deliver a large current pulse into the battery. The entire charging process is actually repeated charging and discharging of the battery. This method can quickly complete the charging of the electric vehicle, but because of the charging current in this way And the voltage is not fixed, so it has a certain impact on the battery.
