The temperature remained at minus 15 to minus 25 degrees for more than a month. The cold was as stable and continuous as ever.

On the streets of Minsk, hundreds of super capacitor electric buses that have experienced the test of five severe winters operate stably on 15 bus lines in Minsk. These vehicles are equipped with the core energy storage device of "Shanghai Zhizao" - super capacitor power system. From the first sample vehicle offline in December 2016 to the first batch online in May 2017, It has always provided convenient and safe green travel for the residents of this heroic city.

Compared with other electric vehicles using lithium batteries, which frequently break out mileage anxiety and operation charging problems in winter, the super capacitor power system produced by Shanghai Aowei technology has always relied on its remarkable product features and advantages, such as excellent low-temperature performance, stable power output and full capacity maintenance, Let Minsk super capacitor bus cope with the cold winter calmly - it operates 20 hours a day, the average daily mileage of single vehicle is 250 km, the maximum is 295 km, and the overall attendance rate of vehicles is 95%. Among them, the vehicle with #1 the factory number has created a record of 400000 kilometers and zero repair.

One belt, one road, is proved to be a classic case of "one belt and one road". It shows the spirit of China's scientific and technological achievements serving the world people. The practice proves that the cold tolerance of super capacitors is verified by the long running Minsk public transport.
