A young colleague was beaten for three years and couldn't wait to buy an electric car. After several months of agonizing, the unit is fine. You can drive to the yard and pull down the root line. This is already a lot better than most office workers. The home community could have been equipped with charging piles, and the residential property quit, saying that it would affect safety and would have to collect any management fees. The result is also a line slow charge. The cruising range of the car is known as 200 kilometers, and it has shrunk sharply in winter. In addition to units, homes and children's kindergartens, other places are afraid to go. The winter did not dare to open the warm air, and the battery began to anxious when it was less than 30%. Going out to eat in the underground parking lot, there is a wall-mounted charging parking space, plugged in a 9-pin DC head, and the “handshake” signal light is green, which means that it is not charged. Tai Hang. Those who dare to eat crabs are caught in the hand. The friends who are brave enough to continue trying can be drastically reduced. The consumption of electric vehicles has been delayed and the charging standards are incompatible. At present, it is still an urgent problem to be solved.
