Pomegranate Cloud / Xinjiang Daily News (Reporter Zhang Wande reported) -40 ℃ low temperature can be effectively discharged 95%! January 28, after three lines of five days of testing, a heavy trucks with ultra-low-temperature power batteries in Xinjiang to complete the cold test. So far, this power battery has been tested in Xinjiang in summer and winter under the extreme temperature conditions of road use.
January 24, Shandong Weineng Environmental Protection Power Supply Technology Co., Ltd. research and development and production of Weineng 300-2 power battery arrived in Xinjiang, by XCMG 49-ton class pure electric heavy truck participation, selected in Xinjiang, Jundong Economic and Technological Development Zone, Qitai, and other places in the three different temperature environments, different road conditions, such as the line for the winter cold resistance test.
The lowest ambient temperature of these three routes ranged from -26℃ to -32℃. Through the test, the Weineng 300-2 power battery can have a range of about 180 kilometers under fully charged conditions, with an average power consumption of about 1.6 degrees per kilometer. -40℃ can discharge more than 95% of its rated capacity, which is consistent with the test report of the test lab. Its mobile energy storage charging gun can complete 100 degrees of replenishment in about 10 minutes, and complete full charge in 30 minutes.
Participate in the test of the heavy truck driver teeth raw - Abliz said: “drive on this pure electric truck, do not have to worry about the fire, run up than the oil car, according to the test results, our tonnage of the car to refueling 300 yuan, charging only need about 100 yuan, and charging is also fast, 20 minutes can be filled up, a little bit of no delay. ”
It is understood that this power battery has been in June 2023 in Tulufan City, Torkun County, Alehui town summer test, its more than 200 ℃ high temperature resistant materials easily capable of high temperature environment.
Zhang, chief expert of Shandong Qingdao Guohua Industry Development Co., Ltd, which is responsible for the development of this battery, said: “The cold-resistant issue of electric vehicle power battery has always been a technical bottleneck. General battery in the cold region discharge about 50%, we use a variety of measures of superconducting technology and materials and manufacturing process is constantly improved, through this three lines of actual testing shows that the battery has reached the -40 ℃ in the low temperature of the effective discharge of 95% of the expected, which is also for our later will be put into the market in Xinjiang the battery has laid the confidence.”
