The 7th China Future Heavy Powertrain Summit 2023 was successfully concluded in Shanghai。More than 150Industry experts participate in the event，Of which 43%FromOriginal equipment manufacturer (OEM) And engine manufacturers。
Enterprise leader of domestic and foreign heavy-duty power assembly industry，Industry professionals and relevant national regulatory authorities such as the International Committee on Clean Transportation(ICCT)，The latest proposals on CO2 and Euro 7 emission standards for heavy duty Vehicles in the European Union were interpreted.。
China Automotive Technology Research CenterCommercial Vehicle integral managementAssessment of key issues，Low-carbon development of commercial Vehicles in the futureMeasuresA series of introductions were made.。
Among，Guo Feng, Director of Sany Heavy Truck Electric Research Institute，At the summit.《Sany Heavy Truck Power Battery Assembly System and Controller are on the way to development and landing》Keynote speech。Among，About“Trinity Tower Battery”Technology sharing，It has attracted much attention。
Trinity Tower Battery
Initiated by Sany Heavy Truck in 2022MTBMagic Tower Battery Integration Technology，R & D industry's firstMTBTechnical battery，Supported by more than ten patents，It belongs to the current industryLightweight power king。
Not only that，The upgraded Magic Tower this yearMTC（Module To Chassis）Extra-large battery，Meet the super large power、Long endurance，Realize the battery core-Module-The weight of the car drops、Reduce the size、Improve the utilization rate of vehicle space，Create the world's longest endurance pure electric Tractor Magic Tower 1165，More than 817 hours on a single charge.5 kilometers，Create a new era of inter-provincial transportation of electric heavy truck，The only pure electric solution for express delivery。
At present, the power battery of Sany heavy truckPACKThe solution has been clearly defined as reduced or shared parts.，Pursue the technical route with higher integration，In addition to basic functionality and security consideration，The improvement of volume utilization rate and mass specific energy and the reduction of cost are the main considerations.，Diversified operation scenarios based on electric heavy truck，At presentForming 210 kWhTo 1165kWhIntegrated solutions for customized development。
Establish a positive R & D system for power batteries，Self-research and master core technology，Technology Leads Electric Heavy Truck Power Battery Assembly，Consolidate the leading position of Sany New Energy Heavy Truck Industry，Achieve the first market share in the country。
Controller under domain control architecture
SANY Heavy Truck Forward Self-developed Battery Tube SystemBMS（DistributedBMSPlatform、IntegrationBMS）。Adopt slave control acquisition module+Master Control Module+Distributed Battery Management Technology of High Voltage Detection Module，Implement the control software、Battery algorithm、Hardware、Independent research and development of upper computer software，Quickly and iteratively upgrade products，Reduce parts and maintenance costs，It's doneSection 6BMS：Master control、High pressure、36sSlave control、48sSlave control、60sSlave control、IntegrationIBMSIndependent research and development。
In addition，Combine with new electrical structure of heavy truck，Positive independent development of a front zone controller。The domain control architecture and controller of SANY Heavy Truck have their own characteristics.，For example, hierarchical architecture+Functional integration，Cross-domain computing communication mechanism，Reconfigurable Security Redundancy and Defense Architecture，The control decision moves up+Nsing execution down and so on，The unique core technology of regional controller is created.，A central gateway is implemented、Vehicle ControllerVCU、Battery management systemBMSAnd water coolingTMSIntegration of controller and other functions。
Car Cloud Platform Digital Twin CloudBMS
Sany has independently developedChina's first commercial vehicle cloudBMSPlatform：1 pairSOX (SOC、SOH、SOE)An accurate estimate of，Improve battery efficiency，Delay battery decay，Improve the operation time，Create greater value for customers；2.Realize the function of fault early warning，Early intervention to eliminate faults，And that safety of the battery is improve，Provide reliable guarantee for safe operation。
Director Guo Feng's brilliant speech was unanimously praised by the delegates.，Future，Sany Heavy Truck will continue to strive for progress.、The courage and boldness of positive development，Hold up“The sales volume of new energy heavy truck is the first in China”And“The First Scene of Electric Tractor in China”Wait, reputation。
