Use big data to make new energy car battery management smarter

With the vigorous development of the new energy automotive industry, the related industrial chain also produces more new space for innovation and entrepreneurship. Anhui Youdan Technology Co. Ltd. took advantage of the opportunity to achieve the application coverage of the new energy power transportation field only 20 months after its establishment. Among them, the company's pilot, Pengyongjun, played a key role.

Big data makes new energy car battery management smarter

In an electric car, the core component is the battery. Our battery management system is the brain of the battery. One of the core functions is state estimation, such as the amount of electricity remaining, how long it can last, and so on.

Pengyongjun told reporters that the current market for new energy vehicles are mainly focused on battery management can not be intelligent, real-time. Mr. Pengyongjun pioneered the idea of a smart battery management system(iBMS) in the industry. Their self-developed system will use two-way wireless data transmission technology and cloud platform data processing methods to provide a complete solution for battery management systems from the terminal to the cloud, and achieve full life cycle online management of battery systems.

The system uses a powerful remote data cloud platform to solve the traditional batteries in software and hardware measurement, fault warning and other aspects of the short board. "For example, if you drive a new-energy electric car, how much power will be left on the screen when you get on the car. If the battery management system is done well, the battery power data will be very accurate, there will be no inaccurate electricity judgment, and the user is trapped on the road. "Our system can estimate the state and health of the battery, as well as the management of charge and discharge, heat management, and balanced management to ensure the safe and efficient operation of car batteries," Pengyongjun explained. "

Under the support of large data, the system intelligently manages the use of batteries, which can increase the error accuracy of the battery's remaining power(SOC) from 5 % to 8 % to 3 % to 5 %, improving the battery equilibrium efficiency and extending the battery's service life.

Start-up companies dedicated to China's new energy car business

"At the beginning of the venture, there was no rich income, but our team devoted themselves to it with enthusiasm and confidence, which has always been very touching. Privately, my little partner and I kindly refer to the company as 'Dan's nest'. "Pengyongjun, who graduated from China University of Science and Technology, has always been enthusiastic about scientific research.

The new energy auto industry has a strong momentum of development. "Last year, we had a turnover of more than one million, and this year we are aiming for one hundred million. " said Pengyongjun proudly. The reporter learned that at present, Youdan Technology has provided complete vehicle support services for Chang 'an Automobile and Chongqing Ruichi. The next step will be to cooperate with Hefei Automobile Enterprise.

Speaking of the industry's prospects, Pengyongjun believes that the new energy car industry is now developing strongly. With the country's new energy car industry, the market demand for battery management system is very large, we are full of confidence in the future of the industry. "Our goal is simply to do the best battery management system. General Secretary Xi also said that happiness is a struggle. My partner and I will go all the way to create our own happiness. " said Pengyongjun.
