Trinity Magic Tower battery attracts much attention | The 7th China Future Heavy Powertrain Summit came to an end

The 7th China Future Heavy Powertrain Summit 2023 came to a successful conclusion in Shanghai.More than 150 peopleIndustry experts participated in the event, 43% of which came fromOriginal equipment manufacturers (OEMs) and engine manufacturers。

Business leaders, industry professionals and national regulatory authorities such as the International Commission on Clean Transportation (ICCT) in the heavy-duty powertrain industry at home and abroadInterpretation of the latest proposals for EU heavy-duty vehicle carbon dioxide and Euro 7 emission standards。

China Automotive Technology Research Center evaluates the key issues of commercial vehicle points management,Future collaborative supporting measures for the low-carbon development of commercial vehiclesA series of presentations were made.

Among them, Guo Feng, director of Sany Heavy Truck Electrification Research Institute, made a speech at the summit"The Road to Positive Development and Implementation of Sany Heavy Truck Power Battery Assembly System and Controller"Keynote speech. Among them, the technical sharing of the "Sany Magic Tower Battery" has attracted much attention.

Trinity Magic Tower Battery

In 2022, Sany Heavy Truck pioneered MTB Magic Tower battery integration technology, with more than ten patents, which belongs to the current industryThe king of lightweight power。

Not only that, this year's upgraded Magic Tower MTC (Module To Chassis) ultra-large battery meets the ultra-large battery life and ultra-long battery life, realizing the weight reduction and size reduction of the cell-module-vehicle, and the improvement of vehicle space utilization.It has created the world's longest endurance pure electric tractor, the Magic Tower 1165, The range on a single charge exceeds 817.5 kilometers, creating a new era of cross-provincial transportation of electric heavy trucks, and the only pure electric solution for express delivery.

At present, the Sany heavy truck power battery PACK solution has been clarified as a technical route to reduce or share parts, pursue a higher degree of integration, in addition to basic functions and safety considerations, mainly take the improvement of volume utilization and mass-to-energy and cost reduction as the main consideration indicators, based on the diversified operation scenarios of electric heavy trucks, at presentIt has formed a comprehensive solution for customized development from 210 kWh to 1165 kWh。

Establish a positive R&D system for power batteries, self-research and master core technologies, and lead electric heavy truck power battery assemblies with technology, consolidate the leading position of Sany new energy heavy truck industry and achieve the first market share in the country.

controller under domain control architecture

Sany heavy truck forward self-developed battery tube system BMS (distributed BMS platform, integrated BMS).Distributed battery management technology using slave control acquisition module + main control module + high voltage detection module, realize the independent research and development of control software, battery algorithms, hardware, and host computer software, quickly iteratively upgrade products, and reduce parts and maintenance costs6 BMS: main control, high voltage, 36s slave control, 48s slave control, 60s slave control, integrated IBM independent research and development.

furthermoreCombined with the new electrical architecture of heavy trucks, it is independently developing a front area controller。 The domain control architecture and controller of Sany heavy truck have its own characteristics, such as hierarchical architecture + function fusion, cross-domain computing communication mechanism, reconfigurable security redundancy and defense system, control decision-making up + sensor execution downward, etc., creating a unique core technology of zone controller, realizing the integration of functions such as central gateway, vehicle controller VCU, battery management system BMS and water-cooled TMS controller.

The digital twin of the vehicle cloud platform is a cloud BMS

Sany has developed it independentlyCommercial vehicle cloud BMS platform: 1 Accurate estimation of SOX (SOC, SOH, SOE) to improve battery efficiency, delay battery degradation, improve operating time, and create greater value for customers; 2. Realize the fault warning function, intervene early to eliminate faults, improve battery safety, and provide reliable guarantee for safe operation.

In the future, Sany Heavy Truck will continue to support the "No. 1 sales of new energy heavy trucks in the country" and "China" with the courage and courage of upward spirit and positive developmentElectric tractorsThe first scene" and so on.
