In the hot summer, high temperature and heat waves swept through! The highest temperature in some areas even exceeds 40℃, which is undoubtedly a strict "baking" test for the safety of lithium batteries in new energy trucks. Zhefu, as an expert in lithium battery thermal safety, has helped Chengdu Universiade Automobile Group Co., Ltd. pass the high-temperature thermal test with years of technical accumulation.
Since 2021, as the main supplier of lithium battery thermal management system of Chengdu Universiade Group, Zhefu has provided strong security for the "big heart" of new energy heavy trucks. Whether it is hot or cold, whether it is urban transportation or long-distance freight transportation, Universiade new energy heavy trucks can run stably and make positive contributions to the city's green transportation.
As the core of new energy vehicles, the power lithium battery has a comfortable working temperature of 25℃~35℃. Below 0℃, the battery storage capacity begins to decrease, while above 40℃, the battery life begins to decrease, and the safety factor begins to decrease.
The "barrel effect" of lithium batteries requires uniform temperature control.Therefore, -Zephyr®BITS, an intelligent thermal management system for Zhefu lithium battery, is adopted.Use liquid cooling heat dissipation technology with higher heat dissipation efficiency.The thermal management unit drives the cooling liquid to circulate, and the working temperature of the battery is ensured to be within the range of 25℃~35℃ through the modes of refrigeration, heating and self-circulation;At the same time, the energy consumption of the battery system is reduced by more than 5%, the battery life is effectively prolonged by more than 50%, and the risk of thermal runaway is reduced.
The thermal management system has the characteristics of automatic control, real-time monitoring, modular design and automatic fluid replacement. The inlet and outlet of water cooling unit are equipped with temperature sensors, which can accurately control the outlet temperature; The self-contained control system can detect the state of each part in real time and diagnose and report it; The water cooling unit can be customized and developed according to the demand; The system matches the expansion water tank and integrates the water level monitoring function, and the system can automatically give an alarm when it is short of water.
As the first "liquid-cooled liquid-heated lithium battery management system" in China, the intelligent thermal management system of Zhefu lithium battery has been rated as "international advanced level" by the Ministry of Science and Technology in June 2017, which fully proves Zhefu's leading position and technical strength in the field of lithium battery thermal safety.
In addition, Zhefu also customized a 5Kw/8Kw/10Kw/13Kw independent lithium battery intelligent management system according to the different capacity of Universiade New Energy Heavy Truck lithium battery. At present, all products of Zhefu can meet the needs of the whole new energy vehicle for thermal management system.

Intelligent management system of 8Kw independent lithium battery
In the field of thermal safety of lithium batteries for new energy heavy trucks, Zhefu is the first choice supplier for many well-known automobile manufacturers, such as Chengdu Universiade, China Heavy Truck, faw liberation, Hanma Technology, Dongfeng Motor, Shaanxi Automobile, SAIC Hongyan, Jianghuai Automobile, Xugong Heavy Truck and Geely Commercial Vehicle, with a market share of 50%, ranking first!
As the main supplier of lithium battery thermal management system for TOP10 heavy truck, Zhefu will provide powerful "heart" protection for more new energy vehicles with leading professional technology and dedicated service attitude, and scientifically promote the green transformation of heavy truck industry.
