New energy vehicles can be charged directly at home with 220V, and manufacturers will give you charging tools. It can be charged in the charging pile built outside, and the card can be charged. Can directly use the 220V power supply at home to charge, electric vehicle charging: 5-6 hours can be, under normal circumstances, when the new energy vehicle factory, the manufacturer will give a portable charger, plugged into the household power supply for charging.
There are three kinds of charging methods for new energy vehicles, which are: public charging pile charging, home charging pile charging, and portable charging. Public charging pile charging: public charging pile charging is usually divided into fast charging(direct current) and slow charge (alternating current). In short, the fast charge is more sufficient and the charging time is shorter. The charge amount of slow charge is less, and the charging time is longer.
Charging method of new energy vehicle: 1. Portable charging; Charging the home charging pile; Charge the public charging stations. Portable charging: When you generally buy an electric car, the car comes with a portable charging cable, which can be charged only by connecting to an ordinary household socket. But the disadvantage is that the charging speed is very slow. Home charging post: With this method, a charging post must be installed in front of the house.
Plug-in hybrid electric vehicle charging method: plug-inPile and take time to charge. This charging method requires a MAC system. And pre-bury it under a section of road, that is, the charging area. Both touch and inductive Macs can be implemented.
Fast charging mode Fast charging, also known as ground charging, is to quickly charge the battery through high strength current, which can charge the battery to about 80% of the electricity in a short time, so it is also often used as an emergency charging. The voltage of fast charge is generally between 150 and 400, and the power is large. Although the fast charging speed is fast and the efficiency is high, the voltage and power requirements of the car are high, and the battery temperature may accelerate the rise of the batteryCause damage.
Slow charge. Slow charging, also known as conventional charging, vehicle charging, is the use of portable charging equipment carried with the car to charge, can use household power and charging pile. The charging current of this slow charge is small, generally about 6A~32A, and the current can be directly carried out by two-phase AC or three-phase AC.
Conventional charging is slow charging: The traditional way of constant voltage and constant current is generally used to charge the car. Small charging station Small charging station is one of the most important ways of charging electric vehicles, charging piles are set in the street, supermarkets, office buildings, parking lots and other places. The electric vehicle driver only needs to park the car at the designated position of the charging station, connect the wire to start charging, the charging method is generally swiped card, the charging power is generally 5 ~ 10kW, and the typical charging time is: recharge 1 ~ 2h, full of 5 ~ 8h.
For example, Tesla models turn on FSD to automatically replenish the vehicle after arriving at the destination; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicle charging plugs are not shared at present, just like mobile phonesCars, SUVs, trucks and other different types of different brands of vehicles can use the same charging plate.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can be set up to three devices at the same timeReady to charge. This wireless charging pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, the charging pad has been opened for pre-sale and will begin shipping in February 2023.1, Apple fast charge 20W. Apple mobile phone currently supports PD fast charge Wireless fast charge and slow charge , the highest support20W Wireless fast charge and slow charge Wired fast charge Wireless fast charge and slow charge , fast charge needs to use the official fast charge head Wireless fast charge and slow charge , and when the phone battery reaches 80%, no longer fast charge. In addition, Apple mobile phones also support wireless charging, up to 15W wireless charging.
2, iphonex up to support 87w fast charge. The iPhone X can support the fast charging feature to keep the phone at 30Up to 50% charge in minutes. For now, the iPhoneX supports Apple's official fast charger with five USB-C interfaces: Apple 18W, 29W, 30W, 61W and 87W.
3, Apple fast charge 20W. Apple mobile phone currently supports PD fast charge, up to 20W cable fast charge, fast charge needs to use the official fast charge head, and when the phone power reaches 80%, no longer fast charge. In addition, Apple mobile phones also support wireless charging, up to 15W wireless charging. From the iPhone8 to the iPhone14, all models of iPhone support wireless charging function.
4, Apple 13 supports PD fast charge, up to 20W cable fast charge, fast charge needs to use the official fast charge head, and when the phone power reaches 80%, Apple 13 for wireless fast charge and slow charge to protect the battery life, will no longer be fast charge in addition, The Apple 13 also supports wireless charging, up to 15W wireless charging.

Charging indicator system: The charging indicator system mainly refers to the voltmeter or charging indicator on the instrument panel, which is used to indicate whether the working state of the generator is normal. If the charging indicator light is on or the voltmeter pointer is lower than 24V while the car is driving, it means that the generator is not charging or the charging amount is too low, and the charging system needs to be repaired.
Contact type. Contact type is also called coupling or conduction type. Contact charging method to a plugThe AC power cable is plugged directly into the electric vehicle's socket to charge the battery. Its advantages are simple and high efficiency; The main deficiency is that the charging current is small and the charging time is long. (2) Induction type.
The charging process of electric vehicles is mainly divided into six steps: physical connection, low-voltage auxiliary power-on, charging handshake, charging parameter configuration, charging, charging end. When charging an electric vehicle, the first condition to be met is the matching of the charging gun and the charging interface, that is, the physical connection. If the charging gun can be normally inserted into the car, the basis for charging is established.
Charging system is currently in our carCar charging system is divided into four parts, fast charge, slow charge, low voltage charge, energy recovery. The fast charging system is mainly composed of a fast charging pile wiring harness power battery pack. When the fast charging pile interface is connected to the vehicle fast charging port, the fast charging pile sends a charging wake-up signal to the BMS, which sends charging current instructions to the fast charging pile according to the rechargeable power of the power battery. At the same time, the BMS suction system high voltage DC relay and high voltage negative relay, the power battery began to charge.
