On April 4, Changjiang Automobile and Xingtai City signed a strategic agreement. According to the agreement, Xingtai City will purchase 300 electric buses from Changjiang Automobile. Jiang Anning, vice president of Changjiang Automobile, said at the signing ceremony that Changjiang Automobile will cooperate with the government of Xingtai City. We will promote high-quality new energy automotive products, advanced management concepts, and leading innovation technologies in Xingtai City, driving the rapid development of the new energy industry in Xingtai City.
Deputy Director of the People’s Congress of Hebei Province and Wang Huiyong, Party Secretary of Xingtai City, took the leadership of the four major teams of Xingtai to attend and witness the signing ceremony
It is understood that the Yangtze River electric bus purchased by Xingtai adopts a full-loaded body structure, six-level vehicle safety control system, active and passive safety such as anti-skid system ASR and ABS anti-lock brake system, and all-round guardian driving. Personnel. Xingtai City expressed at the signing ceremony that Xingtai is accelerating the transformation and upgrading of the industrial structure around the new energy automobile industry. Switching pure electric buses within the city is both a need of the city's development and Xingtai’s actual needs. Xingtai chose Yangtze Electric The bus model is the fancy technology advantage and mature manufacturing advantages of Changjiang Automobile in the field of pure electric vehicles. From servicing the G20 Hangzhou Summit to exporting to the United States in bulk, the pure electric model of Changjiang Automobile has passed the test in many fields.
Cao Zhong, chairman of Changjiang Automobile, once pointed out many times that the public transportation sector is the first to realize the 'overall replacement' of pure electric vehicles, and pure electric vehicles will achieve complete replacement of traditional buses. Changjiang Automobile has a core position in pure electric buses. The comprehensive and competitive advantage of technology to core product strength. Before this, there were a large number of Yangtze River electric buses in Zhejiang, Guizhou, Sichuan, and Anhui.
The battery management system in Changjiang Automotive's core three power technology adopts a distributed architecture, which makes the vehicle layout more flexible, high-current active equalization technology (equalization current continues 2A) and application of advanced thermal management technology (PWM control air cooling, low temperature PTC Heating, thermal insulation function) can effectively balance the temperature field and monomer consistency of the battery PACK, protect and enhance the battery performance to the maximum extent, prevent the battery from over-charging and over-discharging, monitor and predict the status of the battery in real time, and high-precision SOC , SOP, SOH calculation function.
For the vehicle controller, the 32-bit processor can handle more than 150 signals at the same time. The master-slave dual-chip work together. The software part refers to the AUTOSAR 4.0 design, so that the controller always runs safely and reliably. Advanced braking energy recovery The strategy can contribute up to 20% of the vehicle's continuous driving mileage, which greatly enhances the economic efficiency of the vehicle. In the future, Changjiang Auto will develop the next-generation VCU, braking force distribution function and slope adaptive function to improve adaptability to different road conditions. Improve the braking energy feedback efficiency.
In terms of motor controllers, Changjiang Automotive's highly integrated dual-motor controller replaces the original two single-motor controllers, with a power-to-volume ratio up to 19KW/L and a maximum efficiency of 99%. The dual-motor controller actively synergistically enhances the drive. The safety of the system, frequency conversion technology allows the controller to adapt to a variety of complex conditions.
With the continuous optimization of the core three-electric technology, positive development of product design concepts, and outstanding power alternatives, Changjiang Automotive is gradually becoming a leader in 'alternative strategy' from the advocate of the 'alternative strategy' of China's new energy industry. Create a new development path for China's new energy automotive industry.
