As domestic oil prices continued to rise in 2018, the cost of using cars also increased significantly, so the development of electric vehicles and the electric vehicle industry became increasingly prosperous. Electric vehicles learn to drive quickly and are cheaper than traditional gasoline-powered vehicles. Small electric forklifts have many advantages, but there are also durability and charging issues. Sometimes it's full in the charging zone, but when it comes out, when it accelerates, it only takes away a grid or two. How is this? When starting up, the voltage will be lower and the power consumption will be higher. Even if you are not using your small electric forklift, the battery will continue to discharge. Second, when the small electric forklift is fully charged, the stay time is too long. Although the car is not used during this period, the battery continues to discharge, so when a small electric forklift is used, it seems to be fully charged, but when accelerating, it will immediately lose one or two power grids, and what is missing is virtual power. Small electric forklifts can also be damaged if their batteries are stored for too long. The electrolyte in the battery changes and doesn't store electricity better. Then, after a small electric forklift is used for a long time, the circuit will slowly age. At this time, the resistance of the small electric forklift will increase, so the storage capacity of the battery will be transferred between circuits, causing the current to drop due to the excessive resistance. Even if the battery is fully charged, current instability will degrade 2 cells. The battery of this small electric forklift is broken. In the long-term use of electric vehicles, if one of the batteries fails, the resistance of the battery will increase. Battery power will be reduced accordingly. If you find that the electric vehicle battery is insufficient and the virtual power supply is serious, you must check whether the battery is damaged.
