"Three Electricity" system - the core technology of new energy vehicles [ Motor, electric car batteries,Electric Car Charger, Electric control] As we all know, the three major parts of a fuel vehicle are: chassis, engine, and gearbox. The three major parts directly determine the performance, driving experience and even the quality of the vehicle. Therefore, the three major parts are the embodiment of the core technology of traditional cars. The core technology of new energy vehicles is "three electrics": battery, motor, and electronic control. Chassis is still important, but less important as chassis technology has matured. Disclaimer: The electronic control mentioned here mainly refers to the control system of vehicle components, not including vehicle intelligence and automatic/assisted driving What is "Three Electrics" 1. Battery A battery is a device that stores electrical energy and provides energy for driving a car. It acts like the heart and blood vessels of the human body. 2. Motor The motor is the power device of the car, which directly drives the car to run, and its function is equivalent to the muscles of the human body. The stronger the muscles, the better the driving performance of the car. 3. Electric control Electronic control is the management and control system for the operation of various parts of the car, which is equivalent to the brain and nerve center of the human body. The characteristics of "three powers" 1. Sanden is not just hardware, but a combination of hardware and software. Hardware is just the body, software is the soul. 2. Sanden is not an independent component, but a whole that is deeply integrated with each other. For example, a car battery pack needs a battery management system, and a motor needs a motor control system. These systems are all part of the electronic control system.

Can I draw the gun without stopping the charging? [stopping the charging, ev car, Charging Station] Answer: No, please follow the steps below to draw the gun. 1. The fast charging gun has its own lock, which will be locked when charging, and will be automatically unlocked when charging stops, and then the gun can be drawn. 2. There is no lock for the slow charging gun, but there is a lock for the slow charging interface on the body, which is usually locked or unlocked simultaneously with the car, so the slow charging station needs to unlock the door before drawing the gun. 3. When slow charging, unlock the car door first, then press the slow charging gun switch and pause for a few seconds, the slow charging station will automatically power off, and you can draw the gun. However, this operation is risky and is not recommended for common use, and some models may not support it. 4. In case of emergency (such as electric leakage) or special circumstances (such as failure of the charging station`s software and hardware to stop charging), you can press the red [emergency stop button" on the charging station, and then draw the gun. When the charging station fails to charge, you can also check whether the emergency stop button pops up. If you press the emergency stop in a special situation, please restore it in time so that others can use the charging station conveniently.

Can the air conditioner be turned on during electricity? [air conditioner, ev car, charging station] Answer: Yes. 1. Some vehicles need to turn off the system before charging, and then start the vehicle after charging to use the air conditioner. 2. The new vehicle does not have the operation to turn off the system, and the air conditioner is not affected by charging and can be used all the time.

AC EV charger, charging station, basic process of charging [process of charging,charging station,AC charger] Slow charging process Generally, there are on-board chargers in new energy vehicles. Due to size and cost constraints, on-board chargers are relatively small and the charging speed is slow, so this process is called slow charging. During the slow charging process, the slow charging station provides AC power for the car, so it is also called an AC slow charging station. Fast charging process If the charger is placed in the charging station, it is not limited by size and cost, and multiple charger modules are stacked, the charging speed will be very fast, this process is called fast charging. During the fast charging process, the fast charging station provides DC power for the car, so it is also called a DC fast charging station. Not all new energy vehicles can perform fast charging and slow charging. Only large batteries can support fast charging, and small batteries can only be charged slowly. Generally speaking, hybrid vehicles can only be charged slowly, and pure electric vehicles can be both, of course there are exceptions. charging speed Generally, the charging power is used to indicate the charging speed. The higher the power, the faster the charging speed. The calculation formula of the power is as follows: charging power (P) = voltage (U) × current (I) For example, during fast charging: voltage=350V, current=200A, then the charging power is: 350×200=70000W=70KW (kW) 70KW means that it can be charged at 70 degrees per hour. According to the power, you can calculate how much electricity the car has charged. The formula is as follows: charging capacity (W) = power (P) × charging time (t) For example: the power of the household slow charging station is fixed at 7KW (kilowatt), charging time = 8 hours, then the charging capacity is: 7 × 8 = 56KWh (kilowatt hour) = 56 degrees In the same way, the time required for slow charging can be calculated: For example: vehicle battery = 70 degrees, household slow charging station power = 7KW (kilowatt), then the time from zero to full is: 70/7 = 10 hours Note: The charging power of fast charging is constantly changing, and the power will gradually decrease as the power increases; while the charging power of slow charging is relatively small and basically constant, as shown in the figure. Therefore, the calculation of charging capacity and charging time by formula is only suitable for slow charging, and it is difficult to accurately calculate the time of fast charging. The next article will introduce a rough estimation method. The power of various common charging stations On-board charger: 1.8-7KW Home slow charging station for hybrid vehicles: 3.5KW Ordinary slow charging station: 7KW Tesla home slow charging station: 7/11/16KW NIO DC Home Charging Station: 7/11/20KW Older fast charging stations: 60KW General fast charging station: 120KW Newly built high-speed fast charging station: 180KW Tesla V2 overcharge: 120KW Tesla V3 overcharge: 240KW Porsche supercharger: 200KW GAC's latest supercharger: 480KW Xiaopeng's latest supercharger: 480KW The power of the charging station above is only the maximum value. In the actual charging process, the power will be affected by many factors. At the same time, the charging power of the vehicle itself also has a maximum limit. If the maximum charging power of the vehicle is 60KW, even with a 120KW charging station, the maximum power can only be 60KW.

Key benefits of home charging electric vehicle systems. cost effective To install a charging point in your home, you just pay a flat fee at the time of installation, after which you may get unlimited energy from the same source. While your electricity bill may also go up slightly, you'll still save money compared to public charging stations. Depending on the type of charger you choose, its price will vary. There are three types of chargers: Level 1, Level 2, and Level 3. Most EVs come with Level 1 chargers with purchase, but charging is relatively slow. To install at home, an electrician must be hired. more convenient A Level 2 charger will take about four to six hours to fully charge your EV. Let's understand it with an example, suppose you have to wake up early in the morning and drive 50 miles to visit your friend. Also, your EV is about to discharge and you don't have a charger installed in your home. At that time, you have to go to a public charging station. At this time, a home charging station is the best choice. Charge the car at night, drive in the morning and you'll be ready in 6-7 hours. Safety Charging an electric vehicle at home is safer than charging in a public place for a number of reasons. For example, public areas are usually more dangerous than residential areas. When you replace an electric car in a public place, you take the same risk as you would park your car on the street or in an open garage. There's always a chance it could be stolen or damaged by natural elements. On the other hand, by keeping the charging at home, you can make your EV and yourself safer. The process of charging your electric vehicle at home is very safe if you only have a charging point installed in your home. Therefore, it is best to only charge your EV at home.

In addition to Gazprom, there is also aluminum that makes European buyers "unstoppable" [Gazprom, aluminum , home charger] Source: Cable Network [Cable Network News] Three weeks after the "Beixi-1" supply of natural gas was interrupted, even Germany, one of the toughest countries, finally took the initiative to initiate a purchase application for this product that was "sanctioned" by itself. From "absolute refusal" to "active procurement", in addition to "can't stop" for Gazprom, which has been included in the sanctions list, European buyers are also indifferent to the attitude of Rusal, which has not been included in the sanctions list. Some choose not to buy anymore: Novelis, one of the world's largest buyers of aluminum, announced that its European plants will no longer buy Russian metal next year; Norway's Hydro also officially announced that its auto and construction The sector that supplies aluminum products to the industry will exclude Russian-produced aluminum from purchases in 2023. Even in the "matching season" of the aluminum industry in September, the organizer of Barcelona, Spain, who organized the aluminum contract negotiation event in the following year, refused to authorize the Rusal team to participate in the event this time. But there are some options to keep buying: An executive at Paris-based global aluminium supplier Constellium said it plans to continue buying from Rusal next year, with a share similar to 2022 levels because Rusal is not sanctioned , however, he also said no final purchasing decision has been made. A trader admitted that in today's situation, buyers are trying to squeeze as much profit as possible, demanding discounts from Rusal. Rusal itself is working hard: Rusal`s team has become uninvited [guests" in Barcelona, offering discounts to buyers; (in the process of) developing a plan to deliver aluminium directly to the London Metal Exchange (LME) warehouses in Asia. Plans - Seeking Asian buyers. In fact, the "cheap" aluminium offered by Rusal is very attractive to European buyers - per tonne at a time when they are facing record high electricity prices, severely squeezed margins and the threat of a significant reduction in European aluminium production capacity. The discount is $100 to $150. Data show that from March to June this year, the EU imported an average of 78,207 tons of Rusal per month, an increase of 13% over the same period last year.

About one-fifth of Italy's industrial production will stop if Russia cuts natural gas supplies [EV, natural gas, home charger, industrial facilities] Source: Cable Network [Cable Network News] According to media reports, recently, Bonomi, chairman of the Italian Federation of Industrialists, said that if Russia completely stops the supply of natural gas, Italy will have a natural gas gap of 4 billion cubic meters, and if this gas gap is fully applied to the industrial sector , then almost one-fifth of Italian industrial production will cease. This is the second country in Europe to explicitly issue a similar warning after Germany. Earlier, Klaus Müller, head of Germany's energy regulator, the Federal Network Agency, said that once gas supplies from Russia were completely stopped, Germany's natural gas reserves would only be sufficient for heating and industrial facilities to run for about two to two and a half months at most.
