    How Long Does It Take To Supercharge A Tesla

    Jun 22,2022 | Chloe Lacour

    Charges are almost inevitable for everyone. Once the car is charged, there is a solution to the problem. Tesla said in April that there are more than 5,000 Tesla Superchargers worldwide. At the end of this year, Tesla expects to expand the number of charging piles by one cup to more than 1,000, but the total number of charging points has now reached 15,000.

    US charges

    The easiest way (most US home circuits are 120V, 12A): Use the charging cable to charge the battery through the built-in charger. Filling takes 59 hours. 2) Circuit modification (Tesla proposes to convert the circuit to 240V, 40A): The standard charger is fully charged in 8.9 hours. 3) Efficient charging method (wall-mounted charger household circuit 208-250V, 60Hz, 100A): The standard charger still needs 8.9 hours to fully charge. With built-in dual chargers, it takes 4.5 hours to fully charge. 4) Public charging station (the J1772 connector of Tesla's public high-current charging station should be properly charged): the same as the third charging method. 5) TESLA super charging station (no need to charge in the car, directly charge the battery): 30 minutes half charge, 80 minutes full charge.

    Chine charging

    The easiest way (domestic household meter 220V, 30A): use the charging cable to charge the battery through the built-in charger. Filling takes 12.9 hours. 2) Transform the line (apply to the power supply bureau, the current has no upper limit): 8.9 hours for the standard charger, and 4.5 hours for the double charge. 3) Public charging station: the same as the third one. 4) Tesla supercharging station: 30 minutes for half charge, 80 minutes for a full charge.

    Supercharging stations, based on complex electromechanical systems, can power Tesla vehicles. Previously, Tesla has confirmed to the outside world that it is preparing to open authorized dealer stores in South Korea. Tesla's low-cost electric car, the Model 3, will go on sale in South Korea as soon as next year. In just 20 minutes, the Supercharger can charge half a car. Not only that but the Supercharger can also be used for long trips and can be installed on the busiest travel routes in Asia.

    Tesla increases charging prices at U.S. Supercharger stations. While most states saw prices increase by 20% to 40%, some states saw toll costs rising even more. For example, prices in California increased from 20 cents to 26 cents per kWh, New York from 19 cents to 24 cents per kWh, and Oregon from 12 cents to 24 cents per kWh.

    Those most affected by this change will be the Tesla Model 3 buddies. Because Model S and Model X partners have 400 kWh of supercharging station usage per year, Model 3 partners do not have this benefit. Over the past year, Tesla has been adding Superchargers, which have expanded into urban areas and built larger Superchargers. As Model 3 production ramps up, its supercharger utilization rate will increase significantly.

    Tesla's supercharging is also convenient for many Tesla friends, making charging more convenient and fast. What Tesla stands for is that even with higher charging costs, it's still cheaper than gasoline. A Tesla spokesperson said: "Occasionally, we adjust electricity prices to reflect current local electricity usage and usage. The most important principle is that the price of electricity is always lower than that of gasoline. We just want to build a fair system for everyone, and at the same time recover some of the cost, but this will not be the focus of our profitability. In addition, users can check the price of the use of Tesla Supercharger stations in their area through the website.

    2 How long does it take to charge a Tesla

    At present, the sales of new energy vehicles have surprised all my friends. Who would have thought that new energy vehicles could achieve such an achievement in just a few years, allowing more people to understand it and better understand it? Every step basically needs to be down-to-earth, and success is not far away. Little is known about new energy vehicles, presumably, everyone knows it. 

    How Long to Charge a Tesla: Charging Time

    1. The easiest way to charge: Most American household circuits are 120V, 12A, which can directly charge the Model S, that is, connect the charging cable to the 110V plug, then connect the plug to the 110V socket, and then connect the charging cable. The other end of the battery is connected to the Model S, and then the battery under the car is charged through the charger built into the Model S. It takes 46 hours and 17 minutes to charge.

    2. The charging method of the modified circuit: Tesla advocates transforming the garage circuit into 240V, 40A. The Model S, which comes standard with a single charger, takes 8 hours and 19 minutes to fully charge. If the built-in dual charger is optional, the charging efficiency will not improve in this case.

    3. Efficient charging method: Install a high-power wall-mounted charging connector in the garage or outdoors, with a voltage range of 208-250V, 60Hz, and a current adjustment range of 40A-100 a. In this case, the Model S, which comes standard with a single charger, still needs to be fully charged in 8 hours and 19 minutes. The optional built-in dual charger can fully charge in just 4 hours and 9 minutes.

    4. Public charging station: Model S can be charged with the J1772 connector of the public charging station. Some public charging stations are equipped with high-current charging equipment to facilitate fast charging of Model S with dual built-in chargers.

    5. Tesla Supercharger Station Charges Well: The Supercharger Station charges the battery with DC, not the charger in the car. It only takes half an hour to fully charge the battery, and it doesn't take long to shorten it to 20 minutes.

    How Long to Charge a Tesla: Electric Vehicle Fast Charging Stations

    In electric vehicle fast-charging stations, citizens can quickly charge electric vehicles by putting coins into this device. At present, there are two forms of fast charging stations, one is the grid direct charging station. Due to the large space occupied and the need for a dedicated power grid, the investment is huge and the cost is difficult to recover. Therefore, apart from the exemplary behavior of the government, it is difficult to do a good job in commercial promotion. The premise of electric vehicles all over the country is to have a network of charging stations first. The second type of fast charging station is a box-type electric vehicle fast-charging station that uses an energy storage device. The third type of charging station is the coin-operated wall-mounted electric self-driving charging station.

    How Long Does a Tesla Charge: Charging Modes

    According to the technology and use characteristics of electric vehicle power battery packs, there are necessary differences in the charging methods of electric vehicles. At present, there are three modes of charging scheme: conventional charging, fast charging, and quick-replacement battery pack system.

    regular charging

    Regular charging (normal charging) has a lower charging current of about 15A. The conventional battery charging method basically adopts constant voltage or small current constant current charging, and most of the charging time is 5 ~ 8h, or even 10 ~ 20h.

    (1) Analysis of advantages and disadvantages

    The advantages of the traditional charging method are: although the charging time is long, the cost of the charger and installation is quite low, because the power and current ratings used are not important; it can make full use of the low power consumption period to charge well and reduce the charging cost; it can be Improve charging efficiency and prolong battery life.

    The key disadvantage of conventional charging methods is that the charging time is too long, which is difficult to meet when the car has urgent operational needs.

    (2) Meet the requirements of objective conditions.

    The driving schedule of the electric vehicle is designed to be as large as possible to meet the needs of the vehicle for a day’s operation, and it can only be charged by the parking time at night; conventional charging can basically be completed at home, parking lots and public charging stations, because the charging current of the battery quite low. Conventional charging stations are mostly large enough that many electric vehicles can be charged at the same time.

    fast charging

    Most conventional battery charging methods take a long time, which brings a lot of inconvenience to actual use. The emergence of fast-charging batteries provides technical support for the commercialization of pure electric vehicles.

    Fast charging, also known as emergency charging, provides short-term charging services for electric vehicles parked with a high current for 20min to 2h. Most charging currents are 150 to 400 A.

    (1) Analysis of advantages and disadvantages

    The advantages of the fast charging mode are: short charging time; long battery life (more than 2000 times of charging); no memory, can charge and discharge in a large capacity, and can charge 70% to 80% of electricity in a few minutes. Since charging in a short time (about 10 ~ 15 min) can make the storage capacity of the battery reach 80% ~ 90%, which is similar to the refueling time, there is no need to equip a large parking lot when building a corresponding charging station.

    Disadvantages: The charging efficiency of the charger is low, and the corresponding work and installation costs are high; due to the use of fast charging, the charging current is large, which puts forward higher requirements for charging technology and charging safety factors, and the metering and charging design also need special consideration.

    (2) Meet the requirements of objective conditions.

    The cruising range of electric vehicles is moderate, that is, the power needs to be quickly replenished between vehicles to meet operational needs; since the corresponding high current demand may cause damage to the public power grid, the fast charging mode only meets the requirements of the objective conditions of dedicated charging stations.

    mechanical charging

    Mechanical charging, the quick battery pack replacement system, is performed by directly replacing the battery pack of an electric vehicle. Due to the heavy weight of the battery pack, the specialization of battery replacement needs to be strong, and professionals need to be equipped to quickly complete battery replacement, charging, and maintenance with professional machinery.

    (1) Analysis of advantages and disadvantages

    The advantages of mechanical charging are: electric vehicle users can rent a fully charged battery and replace the exhausted battery, which is conducive to improving the efficiency of vehicle use, and the user is convenient and quick to use; the replaced battery can be well charged through the trough period, reducing the charging time. cost, and improve the rationality of car operation. On the other hand, it also solves the problem of charging time, even storage power, battery quality, long driving distance, price, and so on. Timely finding the problems of the single cells in the battery pack and doing the maintenance work well will have positive significance for the maintenance of the battery, and the reduction of the depth of discharge of the battery pack will also help to improve the service life of the battery.

    Several key issues in the application of this model are standardization of batteries and electric vehicles; design improvement of electric vehicles, construction management of charging stations, battery circulation management, etc.

    (2) Meet the requirements of objective conditions.

    The car battery pack is designed to be standardized and easy to replace; in the operation of the car, the battery should be replaced immediately to meet the operation, and the battery charging in the charging station and the car can be separated professionally and quickly; because the rapid replacement of the battery pack should be done professionally, The quick replacement mode can only meet the requirements of the objective conditions of the dedicated charging station.

    To sum up, the above three charging modes have their own characteristics and meet the requirements of objective conditions. Therefore, in the application, the above three methods can be organically combined to meet the actual driving requirements.
