"In winter, park the vehicle indoors as much as possible", "use and charge as you need to ensure effective filling", "the air conditioning temperature is the most suitable 22 ℃, timely adjust the internal circulation". With the temperature plummeting in winter, how to guarantee the endurance mileage of electric vehicles has become the torture of new energy owners. The original "black technology" in the industry: the second generation of thermal management system (Thermal Management 2.0) can save about 20% of the electricity for the user to use in the endurance, which is equivalent to the breakthrough of the endurance of 100km under the comprehensive working condition of NEDC, becoming the most powerful "martial Arts unique skill" in the "winter endurance script". Since December, the installed thermal management system has been automatically turned on for nearly 10000 times for users. Despite the cold wind, the "black technology" of Weima has realized the maximum reduction of the impact of temperature on battery activity, guaranteed the comfortable experience of electric vehicle travel, and provided warm escort for users this winter. The Thermal Management 2.0 system installed in EX6 plus can save about 20% power for endurance, which is equivalent to a breakthrough increase of 100km under NEDC comprehensive working condition. From January to October this year, the first intelligent pure electric SUV Ex5 under Weima automobile, the No.1 strength group of intelligent vehicles, has achieved 14273 cumulative deliveries (number of risks on board) in the year, becoming the first model of the new force in 2019. With the increasing delivery volume, in December, the total mileage of Weima users has reached 200 million kilometers, among which the longest mileage of single vehicle has exceeded 100000 kilometers, which is equivalent to saving nearly 50000 yuan of travel cost for users. The accumulated driving mileage of users is from 100 million km to 200 million km, only taking four months. Weima once again achieved a leap forward growth in the user base, and the cycle of 100 million level driving mileage is reduced by 53% month on month. Weima's battery pack thermal management technology can independently turn on heating and cooling functions in different temperature ranges, and realize all-weather battery pack constant temperature thermal management as the number one strength of intelligent electric vehicles. Weima takes users' pain points as the starting point for innovation, and the original thermal management 2.0 system adds a new winter endurance extension system for the first time, which uses external heat sources to add battery packs and cockpit at the same time Heat can save about 20% of electricity for endurance, and bring users a warm intelligent travel experience. Up to the beginning of December, the user selection rate of Weima electric heating system has reached 42%, and the polar heating system has become a rigid demand of users in Northeast China, among which Harbin has the highest proportion and the user selection rate is as high as 100%. The technical advantages of Wima Thermal Management 2.0 system are mainly the independent liquid cooling design of battery pack, dual-mode heating and winter endurance extended range system, customized electric heating and polar heating system options, further realizing the high adaptability and stability of battery pack in different environmental temperature ranges of - 30 ℃ ~ 50 ℃, ensuring that the battery is kept at the best temperature in the process of discharging or charging Interval, achieve all-weather battery pack constant temperature heat management.
