For a time, "cold" has become a hot topic in society. The continuous low-temperature weather not only makes the electric car driver face the problem of excessive power consumption, but also makes the electric car driver < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%85%AC%E4%BA%A4%E8%BD%A6 "> the citizens who travel by bus < / a > feel chilly. From January 6 to January 14, the public service hotline 12345 frequently received feedback from the public, "some buses are not running < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E7%A9%BA%E8%B0%83 "> air conditioning < / a > heating, especially the new < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E8%83%BD%E6%BA%90 "> energy < / a > tram", "it's too cold on the car" According to incomplete statistics, there are more than 200 related appeals. In response to this problem, the reporter launched an investigation. < / P > < p > < / P > < p > < b > witness < / b > < p > < p > < b > passenger masks emitting "white smoke" safety officers wrapped in "zongzi" < / b > < / P > < p > on January 7, the observation station in the southern suburb of Beijing showed that the lowest temperature was - 19.6 ℃, breaking the lowest temperature record in Beijing since February 1966. On the West bus stop of Muxiyuan bridge, the passengers waiting in line are all "fully armed", and the cold wave weather makes waiting a little painful. "Coming, coming car!" This cry in the crowd is more urgent than usual. The bus has become the pronoun of "Hope", and everyone is looking forward to getting on the bus. No. 665 bus stops, but when passengers get into the carriage, they find that the inside of the bus is not much warmer than the outside. Under each other's masks, white smoke is emitted as usual. Sitting passengers hold their shoulders and necks; standing passengers pull their hands into their sleeves and feel the armrest reluctantly. < / P > < p > "on such a cold day, why isn't it warm in the bus?" In response to the passenger's questions, the safety officer on the bus was also very helpless, "according to the requirements of epidemic prevention and control, the bus should open windows to ventilate during driving, which is < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E7%94%B5%E5%8A%A8%E8%BD%A6 "> electric car < / a >, air conditioning dare not open too much, afraid that the temperature is too low, the electricity can not stare at ah." However, at the request of several old people, the driver still turned up the hot air of the air conditioner. After a while, there was a little hot air on the bus, but it didn't last long. As the bus arrived at the station and the front and rear doors opened, the hot air also "got off" with the passengers. < / P > < p > it is understood that bus No. 665 is a pure electric vehicle with a one-way distance of 26.77 km. The driving route is from luhaiyuan bus station in Daxing District to the South Square of Beijing South Railway Station. The reporter noticed that the South Square of Beijing South Railway Station is not equipped with a charging pile. After route 665 arrives at the South Square of Beijing South Railway Station, it can't be charged. It needs to turn back according to the original route and return to luhaiyuan bus station to be charged. Many new energy bus drivers told reporters that when they saw the percentage of electricity "Hua Hua" falling down, they had no bottom in their hearts. They were really afraid to walk half the way "lying on the ground". The electricity consumption of air conditioning and heating was not small, so they did not dare to drive. On January 11, the temperature rose. The reporter took bus No. 665 again to see if the problem of driving range reduction is better under the weather environment of 0 ℃ or so, and whether the air conditioning and warm air dare to be turned on. It turns out, it's still pretty bad. < / P > < p > "look at my cotton padded jacket, it's actually two layers, but it's still cold, so my feet hurt." The car's security officer told reporters that in winter, no matter whether there is a cold wave or not, as long as the temperature is close to 0 ℃, the car's air conditioning and warm air dare not turn up, for fear that the power is not enough. < / P > < p > after listening to the reporter talking with the security officer about air conditioning and warm air, a passenger also came over and said that he would take bus No. 665 every day. In the cold winter, he was distressed to see the driver and security officer wearing three layers inside and three layers outside. "We got off at the station anyway. They were really hard. The driver sits for two or three hours, and the safety officer can only stomp on the car when he is cold. " < / P > < p > it's the evening rush hour. When we catch up with the traffic jam or wait for the red light, sometimes there are other buses outside the window in parallel or side by side. The reporter can occasionally see several fuel buses, and it seems that we can feel warm across the window. < / P > < p > < b > talk about < / b > < p > < p > < b > it's not warm to turn on the air conditioner in the car in cold weather < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E7%94%B5%E6%B1%A0 "> battery suck no force on

1 11. The reporter came to Chongwenmen bus stop. There are 108 buses and 111 buses. The Beijing Railway Station area also runs 104 buses. These buses are different from pure electric new energy vehicles. They belong to new energy trolley buses. They are" double drives ". Now, will this kind of bus also encounter the problem of air conditioning hot air afraid to turn on? < / P > < p > at the bus station, the reporter saw that thick cotton padded clothes and a large pot of hot water are almost standard for all drivers. The driver who was preparing to leave told reporters that according to the requirements, the air conditioning and warm air on the car must be turned on, "but to tell you the truth, it doesn't work very much. Sometimes when the display temperature is set to very high, the temperature in the car still can't come up." < / P > < p > at Beijing station, a No.104 bus is preparing to start. The driver told the reporter that about one third of the distance of No.104 bus is driven by battery. In winter, in order to make the car warm and protect the passengers from the cold, he thought of many ways, but the effect was very little. In cold weather, the poor discharge ability of the battery is an unavoidable problem. < / P > < p > Liu Baolai, deputy manager of science and Technology Information Department of Beijing public transport group, told reporters that they are very concerned about the battery problem of new energy vehicles, especially this winter, the cold wave and epidemic situation make the battery problem prominent. Novel coronavirus pneumonia needs to be maintained in order to prevent and control the new crown pneumonia. However, the outdoor bus is ventilated, but the outside is very cold. The operation of the air conditioning brings more load to the battery. There are more than 8200 pure electric vehicles in Beijing public transport group. According to the degree of battery, the driving range is between 40km and 150km. From the actual situation, after the warm air is turned on in winter, the driving range of vehicles will decrease by about 30% - 50%. "For this reason, we require drivers to fully charge and then shut down their vehicles in case of special cold weather, so as to ensure that there will be no power loss in the next operation period. If necessary, we will increase the number of vehicles in operation. "
