  7. Add WiFi/improve the value...

[YesAuto electric car] Recently, Tesla officially released the third-generation home charger. The appearance is better and the compatibility seems to have become stronger. The WiFi function is also added, does it mean that it can realize many cool functions through the Internet? If you think so, then you think too much. Today, let’s talk about its experience.

◆Out of the box: Replace with a higher-value glass panel

Today, Tesla has launched a total of three generations of home charging piles. When the Tesla model was first introduced to the country in 2014, it was equipped with the first-generation home charger, and its charging gun used the European standard interface, which was not compatible with the electric vehicles sold in China today; to the second-generation The charging pile, pile and gun are more compact, and the charging gun interface also adopts the national standard. So, what changes have been made to the third-generation home filling pile?

We need to remind everyone that Tesla recently modified the gift cable materials and installation distance of the charging pile installation service from the previous 80 meters to the current 40 meters, and the price is still 8,000 yuan. If the charging pile is more than this number of meters away from the distribution station, you need to pay an additional fee in meters. The single-phase cable and the three cables are at the same price, which is 70 yuan/meter.

◆No surprises in charging speed

Has the charging speed of the new generation of charging piles improved? the answer is negative. According to official information, the new generation of charging piles still supports single-phase and three-phase power. If single-phase electricity is used, the charging power of all Tesla models that the pile can give is 7kW, and if it is three-phase electricity, the maximum power that the pile can give to Model S/X is 16kW, and Model 3/ The maximum power of Y is 11kW.

We started the test at 9:17 in the morning, and the initial power was 19%. By 2:17 in the afternoon, the power reached 66%, that is, 47% of the power was charged in 5 hours, and the average 9.4% of power was charged per hour, which is equivalent to the battery life of 47km charged per hour. This charging speed performance is not There is no difference with the old charging pile.

◆Add compatibility mode, other cars can also be charged

In this update, Tesla also added a Wi-Fi wireless connection to the new generation of charging piles, which was not available in the previous two generations of home charging piles. According to common sense, Wi-Fi is provided to allow charging piles to connect to the Internet to achieve remote control, but the official only stated that its function is to allow charging piles to support OTA remote firmware upgrades.

Why add access control function? To understand this problem, we need to know that the charging logic of Tesla's home charger is different from that of other brands. Charging piles of other brands will have an authorization process before charging. If there is no authorization, don't charge any car and avoid rubbing power completely.

Therefore, if there is no access control function, then it is equivalent to whoever holds a charging gun, as long as it is plugged into his car, theoretically, he can charge his car, and it is easy to be charged. If the user chooses to charge only Tesla, the charging pile can only charge Tesla brand models, which avoids the situation of rubbing power to a certain extent. However, there is a bug here, that is, other Tesla vehicles can be charged… Therefore, it is recommended that Tesla can add an OTA option in the future that allows only specified models to be charged.

Another problem is that even if the compatibility mode is turned on, this pile still has compatibility problems. We have found three other electric cars of other brands, namely Roewe Ei5, Zero Running T03 and Xiaopeng Motors P7. Among them, only Xiaopeng Motors P7 supports charging, and the other two cars did not respond.

From this we can find that although Tesla’s third-generation charging pile has added a compatibility mode, not all electric models can be charged on the pile. It seems that only those models with charge and power control at the car end can be relatively well compatible with Tesla's third-generation supercharger. In addition, if the Tesla Supercharger is connected to three-phase power, there are few models that support three-phase power charging, so it is believed that there will be fewer models that can be compatible with the pile.

Finally, let's talk about the installation process. Since we are replacing the disused Tesla’s first-generation charging pile with the third-generation charging pile this time, the process of reporting with the property and power supply bureau and the process of laying the power supply cable is omitted, but directly Replace the charging pile. From the perspective of the entire installation process, there is no obvious difference from the second-generation charging pile. It is to install a base first, and then hang the charging pile body on it and fix it. It is just an extra step to connect the charging pile through WiFi for debugging. A step of.

Full text summary:

When I heard that Tesla had released the third-generation charging pile, I expected it to be like the third-generation supercharged pile, giving us a significantly better experience than the previous generation. But after the actual experience, I feel that its overall change is not big. The addition of Wi-Fi is currently only for the convenience of adjusting parameters that users do not need to care about and for wireless OTA upgrades. This design seems to be mainly for the convenience of staff debugging, and is of little value to users. However, its plug-and-charge and the charging experience of remotely opening the charging port cover by pressing the charging handle button is still better than most of the charging experience on the market that requires authorization and manually opening the charging port cover.
