Charging time for tesla models. “It makes no sense to charge from a regular outlet.

"How to charge?"- this is probably the first question that arises in a person interested in electric vehicles. And in the conditions of Belarus - the question is doubly interesting. We will approach it with the example of the European Tesla Model S as the first decent electric car that is now on the market. We continue the promised cycle of publications.

To achieve this goal, the company is working not only with more efficient motors and larger batteries, but also with a network of charging points. In this cheaper model, since the sale is also more expensive, with a larger battery that provides another quarter of the range. And, as Tesla shows, five such stations should be built in Poland. All are planned on the highway - two on the A2 and A4, and one on the chick to be such that the Tesla driver could get from Berlin to Warsaw and Gdansk or from Dresden to Krakow - stations will be built in the Poznań area, Łódź, Torun and Grudziadz Wrocław and Katowice .

Let's remember physics: volts, amperes and kilowatts

First, some basic information about electric current. If you did well in school and know how volts differ from amps and kilowatts, you can safely skip this information.

The battery capacity of a car is measured in kilowatt-hours, in our case the battery has a capacity of 85 kWh. This means that, theoretically, it can produce 85 kW of power for one hour or, respectively, 85 hours to produce 1 kW. To replenish the battery, you need to do the opposite - apply 85 kW to it for an hour, or apply 1 kW to it for 85 hours. Of course, in reality there are losses, and charging does not always go at the same speed, but the general idea is this.

This does not mean that the official start of sales in Poland - the stations are created primarily for customers in Western Europe who want to come to our country to drive or arrive by ferry from Scandinavia, which is experiencing a boom in alternative car propulsion systems.

Poland is not the only country in Central Europe where Tesla stations are to be built. The company also scheduled it in Czech Republic, Slovakia and the Balkans - on the Adriatic coast, as well as in the corridor connecting Western Europe with Istanbul.

A watt as a unit of power is a volt (voltage) multiplied by an ampere (current). To understand the difference between current and voltage, the water analogy is best. Voltage is, figuratively speaking, the pressure of water, and current strength is the diameter of the pipe. To pump the same volume of water (kilowatt-hours), you can, for example, pump water through a narrow pipe with a high head or a wide pipe with a low head.

Next year, the manufacturer planned more than 60,000 deliveries. Opportunities will be limited for some time because Tesla has to order batteries from Asian subcontractors today. Soon, however, it is planned to begin construction of the so-called. Until then, the network of charging stations should be dense enough to allow electric car owners to comfortably travel between cities. After 40 minutes, you can charge 80 percent. battery, and from 75 minutes to 100 percent.

One battery charge allows you to travel up to 460 km. For many years we have been following the latest trends with interest and developing innovative business segments. There is no doubt that the global automotive industry is gaining momentum towards zero and low carbon vehicles.

If the pipe is wide and with high pressure, then the filling process is fast. Otherwise, slowly. For high voltage good conductor insulation is needed (thick pipe wall), for high current strength - a sufficient cable cross-section (pipe thickness).

Now let's talk about sockets. A typical household euro socket has a nominal voltage of 220 V and a maximum current, usually 16 A or less. If we multiply the voltage by the current or 220 V × 16 A, we get the maximum consumer power of 3520 W, or about 3.5 kW.

As emphasized by the Plotz Group, in parallel with the project "Ongoing analyzes regarding the launch of charging stations for test vehicles in Poland and the Czech Republic" carried out in Germany. “Final decisions will be made by the end of this year,” the company's press service said.

There are currently over 550 filling stations in Germany, mostly under the Zvezda brand. We are organically increasing the market share, - said the Deputy Chairman of the Plock Group. It's tempting, yet incredibly free, to travel in your own car across Europe. It turns out that with an electric car and battery charging at free charging points, which network in the West is very well developed, this is possible. Unfortunately, there is a long-standing "refueling" problem. About the facts and myths related to the electric car, we are talking to one of a dozen Polish Tesla owners.

Another common type of outlet is three-phase, with an interphase voltage of 380 V (the voltage of each phase is the same 220 V). It is less common in everyday life (electric stoves), but is ubiquitous in production, where powerful equipment is used. Most often, a three-phase socket has the same maximum current of 16 A, which, taking into account three phases, gives us 220 V × 16 A × 3 = 10.5 kW. This European-style socket has a red color and five contacts arranged in a circle. For convenience, we will call it a red rosette.

The mentioned Tesla has been registered in Poland so far only 12 units, while in the world it already exceeds 000 copies. The amount you pay for Tess is not the lowest. The cheapest option is the cost of 70 thousand. American dollars. Can this cost really be recouped using such vehicle? In a conversation with the site, David Guzenda - a Tesla S customer who runs a "My Tesla" fan page on the Internet - talks about how the electric rider works and whether it really benefits the wallet.

There are also single-phase sockets for 32 A ( of blue color), but they are extremely rare.

Since the power supply uses alternating current, and the battery is charged with constant current, it must be "straightened" using a charger. The same thing happens when you charge your laptop or mobile phone. Only in the case of Tesla, the charger is installed inside the car. The Model S comes with one 11kW charger as standard, and you can optionally add a second charger for a total charging power of 22kW.

Among other things, it is the safest car in the world - it is difficult to "roof" due to lowering the center of gravity, it has more space for luggage - 2 luggage. The engine is the size of a watermelon and has a power of 400 horsepower, maximum torque is immediately available, and the cost of driving 100 km is only 6 PLN. In addition, automotive software may provide additional features in the future.

The car will not rust because it is made of aluminum. The number of innovations implemented at the same time fluctuates compared to other cars. Throughout the year, we work hard to make our videos and videos more accessible to our readers and readers, better understand and manage our assets, businesses and savings better.

Also included with the machine is the so-called Mobile Connector, which is similar in shape to a charger, although in fact it is just a smart connecting cable. For the German market, two adapters are included: one for a regular Euro socket, the other for a three-phase red socket. And that's just what we need! In the case of the American Model S, you will receive a set of single-phase American sockets of various capacities and the inability to charge from a three-phase socket in principle! This is the main and very significant limitation of "American women".

When you read opinions, have you heard any voices against "electricians"? Weren't you afraid that an electric car might be more of a burden than a convenience? For the last 2 years I have not had a car, so I had nothing to fear. What did the electrical look like?

Tesla does not have dealers, he buys cars only on the Internet - it's cheaper for her. You bought a car in Norway. Is Tesla cheaper there than in Poland? Electric vehicle manufacturers are increasingly trying to convince us that buying an electric car is a good choice. Relatively small coverage, long loading times and a noticeable reduction in winter opportunities make it difficult to convince them to purchase such a vehicle. Let's put this shortcoming aside. Let's see if it's worth buying an electric car, at least theoretically.

Mobile Connector

We will first select a vehicle for consideration. Under the magnifying glass, we will take a car that can replace the average Smith car. This car is relatively small in size, but it offers plenty of room in the middle. Burning in the city is in this car according to the catalog of 6 liters of gasoline per 100 km. Now it's time to calculate - is the electric car charging?

This does not change the fact that this is the amount that must be paid monthly. The amount of the rental fee depends on the declared mileage of the car and the service life that we choose. Because in Poland we have cold winters and hot summers, let's get out of this average. So, let's take the approximate speed of this operator. However, this does not affect the cost of a one-time payment. To bring the battery back from 0% to 100% we need 22 kWh. This means that the price of one charge is PLN 11.

The car itself, destined for Europe, houses the Mennekes Type 2 charging connector. Introduced in 2009, it was adopted as a single European standard for electric vehicles. Today it is used in Renault Zoe and BMW i3. The main advantage of Type 2 is the ability to work with both constant and alternating current, with one or three-phase network. In addition, it is much safer than conventional plug-in connections, since the transfer of energy begins only after the plug is fully connected and the car and the cable “agree” among themselves on the type electric current and charging power. In the case of the American Model S, the car will have a connector of its own unique design, more compact, but not supporting three-phase current.

Unfortunately, due to the rental of batteries, we have to add another additional fee, previously mentioned. This result will be compared with Fabia's combustion catalog in the city. On the other hand, it would be better if the car chose a value for driving on the road. Consumption of the urban population is 6 liters of gasoline per 100 km in Skoda.

This is 20 g less than Zoe's. If not for him, the price per kilometer on an electric car would be 3 times lower than in Fabia. The problem is that then it is likely that the more expensive car will be at the time of purchase. It is impossible not to return to the shortcomings mentioned at the beginning. In addition to the lack of profitability of the math, electric vehicles still have many disadvantages that are too problematic for today's drivers. In such a car, we will not drive along the route, it will be shorter in winter and even in summer - 150 km, this is still a distance that makes us constantly calculate whether we have enough energy to get home or one of the few charging stations.

First charge - at the car wash!

If we want to be green, we stay with hybrids. These are cars that give EVs the edge in the city without forcing them to give up, providing the freedom guaranteed by the internal combustion engine. However, this fact is to compensate for low exploration prices.

Thread: Electric car worth it?

Due to Tesla's equipment and the fact that this is a new car, we have to choose it from a competitor of this particular group. To drive 100 km, he needs an average of 7 liters of fuel. What is important is the "mental attitude" to a new or "fashionable" problem.

Now that we have dealt with the cables and sockets, you can start charging. For the first time in Belarus, our car was charged at the Peugeot car wash. The employees were sympathetic to the electric car and allowed to use their three-phase red socket. As it turned out, powerful professional car washes high pressure use just this type.

Thread: Is an electric car worth it?

Chests condition, deployment cost is terrible, big and unprofessional, and it's hard to say that the owners of this car only use it on long distances. The cost of running electric vehicles is here in the first post. Of course, electric vehicles are also subject to inspection, but they will be limited to checking equipment, engine condition, connections, batteries, or replacing items that may indicate a risk of failure or threat to the user.

The electric car invented by the French? With a 40 kWh battery and an efficient driving style, you will cover a distance of approx. 240 km. How to charge the battery? Simply, on a typical 240-volt American outlet, a cable called Mobile Jack. How long does it take to fully download?

Open the trunk, take out the Mobile Connector, plug it into a power outlet. The indicator lights up green - everything is ready for charging. On the opposite side of the cable is a handle with a button and a Type 2 connector. We press the button in the handle, and a door opens in the taillight on the driver's side. We insert the connector, three LEDs in the headlight start blinking green - charging has started!

What's under the hood? Another trunk! With effective stop planning, you have no problem! It's a high price, but in the long run the savings are reasonable! Where did power come from? The first solar power plants have already been launched! This is the first 100% electric car tested in an editorial.

Obviously, compared to regular cars, Japanese car sales seem endless. But in the category of 100% electric vehicles, List is certainly a performer and plays a pioneering role in changing people's mentality and combating unfounded myths about the electric motor. Therefore, it deserves our attention.

On the screen in the Tesla cabin, you can see the mains voltage of 230 V (in our case, phase) and the current strength. The car gradually begins to increase the current and at the same time monitors the voltage. If suddenly a voltage drop is detected with an increase in power or its fluctuation, the current strength will be limited. This is how network overload protection works.

How it looks outside and inside

Headlights, although the aerodynamic profiles look very odd. And the stops are also unconventional. The headlight's conflicting looks make them seem odd, dictated by aerodynamic considerations but with an aesthetic result in cartoons or Mickey Mouse drawings. That's when the vertical stop and at least the interesting look of the tailgate raises a lot of eyebrows. Therefore, we are talking about a strange car for those who appreciate the design of the car in the first place.

There are also conflicting details: the shift lever is taken by a fancy joystick, and there is a small display on the speedometer and other basic information above the steering wheel. Interestingly, if looks can cause hoops, the front of the cabin will prove to be very spacious, with ergonomic displays and buttons. From a driver's point of view, everything is just fine and doesn't really see criticism unless we're talking about unfounded premium claims.

In our case, the wiring was quite new, so the car quickly reached the maximum 16 A for this type of outlet and started charging at a power of 11 kW. About a quarter of the battery needed to be charged to a "full tank" and the estimated charge time was 2 hours. Not fast, to say the least. Nevertheless, while the car was put in order, it was possible to charge almost completely. Good for a start. A full charge from the red socket will take about 8 hours.

If the car is closed during charging, the Mobile Connector is blocked in the connector and all illumination is turned off so as not to attract too much attention.

After a trip around the city, it's time to check the charging speed in the garage from a regular outlet. And here came the bummer: the Mobile Connector blinked red four times, which is an indication of the lack of grounding. No "ground" - no charge. Very often, electricians are not serious about grounding, so you can find ungrounded or “zeroed” sockets everywhere. So the presence of a euro socket in the wall does not guarantee you the opportunity to recharge from it. Even if you are lucky and there is a ground, the charging speed will be four times slower than the red socket, since the maximum power in this case is only 3 kW. A full charge will take over 33 hours!

If you want to charge at home faster than the red outlet allows, you must optional equipment. One charger installed in the car, by default, allows you to charge at a power of 11 kW. The optional second one can be installed directly at the factory or added later, in which case the maximum charging power will be 22 kW. In addition, you will need to install the High Power Wall Connector (HPWC), which is almost a complete analogue of the Mobile Connector, only installed permanently and has a thicker cable.

If HPWC is the only alternative in America, in Europe you can buy a similar device with a Type 2 connector and the corresponding cable. But with a third-party cable, you won't be able to open the charging hatch by pressing the button in the cable. You will have to open it from the central screen or from a mobile phone through the application, which is not very convenient. Power of 22 kW will allow you to fully charge in 4 hours.

But perhaps the biggest problem with 22 kW charging is allocating the appropriate power. If you can't get 22 kW at the car parking lot, it doesn't make sense to order a second charger in the car and HPWC. For convenience in the garage, it is best to purchase a second Mobile Connector and use it as a stationary one, permanently connected to a power outlet. And carry the original with you in the trunk, just in case you need to recharge on the road. Most likely, on the way you will be charged from a regular (if you are lucky with grounding) or a red outlet. Even if you suddenly find a Type 2 connector with a power of 22 kW at the Belarusian electric filling station of the future, then 4 hours is still too long for recharging during the day. In the case of charging at night, the difference of 4 or 8 hours does not matter.

Why cities don't need electric refueling

Now let's talk about electric stations. This is the most asked question to the owner of an electric car. Oddly enough, in the city, Tesla owners do not need electric stations in principle. The real power reserve is 300-350 km, in the worst case (when minus 20 Celsius and traffic jams) it drops to 200 km. In the evening you put the car on charge (just like a mobile phone), and in the morning you always have a “full tank” (if the socket is red or HPWC). In the case of a conventional outlet, a “full tank” may not work, especially in winter. Therefore, the best electric refueling is a red outlet in your home.

Is it possible to operate a Tesla normally if you do not have a garage or parking space? Since the installation of the home red socket was delayed, and the euro socket in the garage did not have grounding, we drove the first thousand kilometers in the "parking near the house" mode. Thanks to the kind people at the Peugeot car wash, at Atlant-M Britannia and DAF Trucks, we used their red sockets every few days. In all cases, there were no problems, with the exception of two points - you have to wait a long time for charging to complete and wipe the cable from dust and dirt before putting it back in the trunk. Night charging is much more pleasant: you sleep - the car is charging. During the day it is very inconvenient.

The Model S can be charged at any time without having to wait until it is completely empty. The battery has no memory effect, will not recharge if you leave it plugged in for a long time. The manufacturer generally recommends leaving it connected all the time until you drive. This is especially important in winter when it is very cold. You can remotely turn on the climate control and warm up both the interior and the car battery from the mains. Another handy feature is the automatic marking on the map of all the places where you have ever charged. Thus, after a while, a map of "electric filling stations" is formed.

Is it possible to "reset the extension cord" from the apartment? Theoretically yes, practically no. Firstly, it will be unsafe in rain or snow, and secondly, charging from a regular outlet takes a catastrophically long time. Therefore, in order to use an electric car normally, installing a three-phase red socket near a permanent parking place at work or at home is a top priority that should be taken care of in advance.

to install three-phase socket at home, you, in a good way, will need to make a project, go through the stages of approvals, mount sockets, lay cables and, it is possible, install an additional electricity meter. All this can be undertaken by a specialized organization that deals with electrics. In each case, the timing, cost, availability will vary electrical power. Therefore, before thinking about buying an electric car, you definitely need to understand for yourself how you will solve the issue of charging.

But what about the electric refueling on the A-100, you ask? After all, the slogan on a huge poster reads “Electric cars refuel here,” and on a special pedestal, like a monument, stands a lone Nissan Leaf. As it turned out from a conversation with the gas station staff, they have no idea how it works: “The bosses are playing this electric car, and we don’t know anything.”

On the second attempt, with a request to clarify the situation, the employee went to his superiors, who did not even deign to leave the office and look at the first living customer of an electric refueling station in the country. "This is for official use"- said, as she cut off, the lady at the cash desk after a visit to the authorities.

We approached Nissan and found out that the “subcompact car” is charged by “slow” charging through the old Type 1 connector. In any case, without dancing with adapters that are not there, Model S will not be able to charge there, and it will take too much time. Thus, "electric refueling" on the "A-100" is simply not a completely correct marketing ploy.

Today, there are three ways to charge your Tesla car.

At home with a standard Mobile Connector charger
At home with an optional, more powerful High Power Wall Connector charger
at charging stations

Tesla Model S Charging Time

Consider required time battery charger with maximum power 85 kWh.

Charger - 29 hours
using a special adapter, standard socket NEMA 14-50 and electrical network modifications- 9 hours

Charger (requires power grid modification) - 9 hours
+ Twin Chargers* (requires power grid modification) - 4.5 hours

*Twin Chargers - dual charger. Located directly in the car, allows you to speed up the charging time by half. The option is available when ordering a car.

At the charging station Supercharger everything is like at home. We drove up to the post, inserted the charger into the compartment, and that's it. It remains only to wait.
It takes approximately 20 minutes to charge your 85 kWh battery in your electric car by half! In 40 minutes, 80% will be replenished, and in an hour and a half, the Tesla Model S 85 kWh will be fully charged. And by the way, it's completely free. After all, Tesla Motors does not charge money for using the Supercharger!
