Meteorological charging station

If you are an electric car driver, it is important not to panic in winter, if the power of the vehicle is insufficient.

Is this a Tesla model? 3 The story of the driver. When he arrived at Tesla Super Charging Station in Winnipeg, Canada in quite cold weather (close to minus 30℃), he found that his car could not be charged. This model at that time? The battery state of 3 is only 1 1%.

After the owner came to this charging station, the original plan was to leave after charging, but after connecting the super charging pile, the car showed charging 0 kW. This is not a good phenomenon, because the car needs a lot of energy to heat the carriage, and it is MINUS 28℃ outside, so it must be charged quickly.

But what makes people collapse is that the driver has changed another charging pile and still can't charge it. So, he changed another one, another one ... until he tried all the charging piles in this super charging station, he still couldn't give his own model? 3 charge. On the display of the large screen of the vehicle, either the charging pile is not charged (wrong) or it is charged at 0 kW.

This Tesla super charging station did not post a warning of failure or damage to some charging piles. Obviously, the whole charging station is running normally. However, all the charging piles in this charging station can't be charged, and they can only be helpless.

Later, under the ice and snow, the owner had to choose other schemes. Because it is the weekend, Tesla's customer service phone does not support the service. After all these troubles, the battery capacity of the vehicle has dropped to 10%, so the owner must find a secondary AC charging point, that is, the Tesla destination charging point, which is as long as 10 km (6 miles) from here.

Finally, it took the owner a while and finally found a new charging station. At that time, models? The battery power has dropped to only 2%, which is quite dangerous in this case, but at least this AC charging pile will start working immediately after it is plugged in. Although it is only a few kilowatts, it is enough for the owner to get out of the embarrassing situation of being trapped in ice and snow.

Although most of us know this problem, it is very important for all new and future electric vehicle drivers to know the specific details of charging in cold weather.

The root cause of the problem is not the external temperature of-30 C, low charging state or damaged charging station. The fundamental reason is the limitation of cold battery and its low temperature charging (in most lithium ion chemical reactions).

This is an embarrassing charging experience, but it also reminds many electric vehicle drivers that electric vehicles are really not "obedient" at extremely low temperatures. It may be better to keep the vehicle at a certain temperature before charging in winter.

According to Xiang Ge, Tesla's super charging stations all adopt DC mode, and the destination charging station adopts AC mode. If you can't charge the DC charging pile, you may be able to solve this problem by switching to AC mode.
