When we have no electricity in the electric car, we will think of charging. In fact, we don’t know how to charge the electric car. Let me tell you about the three charging methods common to electric vehicles.
1. Constant current charging means that the current is constant during charging. If multiple batteries are connected in series, the charging method in this way is generally selected, and the current during charging is small, so the charging time is long, which is generally used by our family.
2. Fast charging, this charging method allows the electric car to complete charging quickly. In a short time, this method can deliver a large current pulse to the battery. The whole charging process is actually repeated charging and discharging of the battery. This way, the charging of the electric vehicle can be completed quickly, but because of the charging current in this way. And the voltage is not fixed, so it has a certain impact on the battery.
3. Constant voltage charging refers to the amount of voltage that remains constant during charging. In the initial stage of charging, the battery resistance is very small, the charging current is very large, and after charging for a period of time, the internal resistance of the battery increases, and the charging current becomes smaller at the later stage of charging, and the charging method is relatively fast.
