The function of the charging pile is similar to the refueling machine in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential quarters parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform operations such as the corresponding charging method, charging time, and cost data printing. The charging pile display screen can display data such as charging capacity, cost, and charging time.
Car wireless charging
At present, the mainstream wireless charging can be divided into two methods, namely: electromagnetic induction type and magnetic field resonance type.
1. Electromagnetic induction
The alternating current of a certain frequency in the primary coil generates a certain current in the secondary coil clock through electromagnetic induction, thereby transferring energy from the transmitting end to the receiving end.
2. Magnetic field resonance type
It consists of an energy transmitting device and an energy receiving device. When the two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy with each other.
There is no doubt that the biggest advantage of wireless charging is that it eliminates the wire link. During the charging process of an electric car, users are eliminated from the three actions of getting off the car-pulling the charging gun-plugging in the charging gun.
The charging station is an energy station that provides charging and quick replacement of the power battery for the power battery of electric vehicles. Electric vehicles require their electric energy to be replenished for continuous driving. These charging methods are embodied in different charging modes. Also in the way of quick battery replacement, after the battery pack is removed from the car, the battery is charged in a certain mode. There are AC, DC mode, limited voltage, current limit mode and so on. The kind of charging method is actually how much current and voltage and how long it takes to charge
Charging method: The charging method can be simply divided into vehicle charging and charging after the battery is separated from the body. The charging methods include fast charging, regular charging and slow charging. These charging methods are embodied in different charging modes. Also in the way of quick battery replacement, after the battery pack is removed from the car, the battery is charged in a certain mode. Batteries with different characteristics have different charging modes; batteries with different requirements have different charging modes. There are AC, DC mode, limited voltage, current limit mode and so on. The way to charge is actually how much current and voltage and how long it takes to charge.
