Team R&D direction

Focusing on the key technical requirements for the development of Ningbo automobile industry chain, the project plans to build a common technology platform for automobile lightweight and intelligent, focusing on the technical breakthrough of four special tasks, so as to form a "closed-loop" industrial technology system represented by advanced automobile design technology, complex manufacturing of vehicle parts, new energy power system and vehicle driving performance testing technology, It provides the industry with parts and system level integrated solutions, which can serve the rapid development of the whole vehicle and parts industry such as conventional passenger cars, new energy vehicles, trucks, RV, smart cars and special modified vehicles, and promote the deep integration of production, learning, research and use.

Team research achievements and application fields

In terms of lightweight design and manufacturing of automobiles, the performance design theory and method of major equipment and engineering structures have been established, and the conceptual design technology of body structures has been proposed, which can greatly shorten the conceptual design cycle of body structures, and has won the second prize of Science and Technology of China's automobile industry.

Body structure concept design software

Based on the team's independent body structure design technology and composite body structure fine simulation technology, a variety of body bearing structures including carbon fiber reinforced composite upper body, crash beam, battery box, etc. were developed, which achieved mass reduction of body structure.

The first self-propelled RV with a load-bearing body chassis was launched in China. The vehicle structure adopts advanced composite material technology, which greatly reduces the vehicle weight and energy consumption; Combined with multi-sensor fusion technology, 5G communication and cloud big data analysis technology, real-time monitoring and mobile phone remote control of RV health and usage are realized.

The man vehicle cooperation system is established to realize the digital judgment of driving comfort; The physiological signal database was established, and the physiological detection model was established through the fusion of the complexity of multimodal physiological signals; Develop artificial intelligence algorithm to achieve high-precision and high timing synchronization control of vehicles.

Based on the offline training database, the gray wolf optimized MKRVM was completed using MATLAB to build the battery aging model;

The battery charging data in the test database is used to simulate the real-time battery hardware circuit signal acquisition through the LabVIEW file I/O interface, read the battery charging data line by line and store it as a local EXCEL file as the real-time battery charging data. When the charging cut-off current is reached, the saved EXCEL file is imported, and the charging data is intercepted to extract the online aging characteristics.

Embed the MKRVM optimization model after training into LabVIEW to complete online estimation of battery capacity and display it on the BMS interactive interface.

The characteristics of the ternary lithium battery power battery pack for vehicles with metal heat dissipation.

1. Good temperature consistency: the temperature difference between any two single batteries can be controlled within 5 ℃, which is conducive to improving the endurance mileage;

2. Good safety: it has certain energy absorption characteristics, but will not collapse, which can effectively prevent external impact;

3. Low cost: the total cost of the cooling system accounts for about one tenth of the whole power battery pack (mass production will be lower).

The lightweight design method of power battery pack is studied, which meets the requirements of mechanical safety and takes into account the thickness of partition plate, material matching and shape optimization.
