CTOnews.com December 14 news, Ningbo Puri Junsheng Automotive Electronics Co., Ltd., led by Ningbo Junsheng Automotive Electronics Co., Ltd., with the key participation of Ningbo Junsheng New Energy Research Institute, announced that the first phase of the R & D project has made a breakthrough and is expected to be completed by the end of December. Based on the platform resources of the innovative consortium, Junsheng Electronics has launched a new round of research and development and industrialization of key technologies of energy management system for electric vehicles on 800V high-voltage platform.

According to the innovative consortium plan, the key technology of the energy management system of 800V high voltage platform electric vehicle has become the key sub-topic of its first project. Combined with the reality of China's new energy vehicle market, this round of joint innovation and development will focus on high efficiency 800V fast charging boost key technologies, highly integrated 800V multi-in-one key technologies, 800V high voltage platform energy management system charging control technology, 800V energy management system structure, and 800V energy management system development and verification research.

It is generally believed that the 800V platform architecture has been proved to be a feasible scheme to improve the charging speed. Since 2022, Hyundai, Avita, Xiaopeng and Lutes have successively launched 800V high-voltage architecture models, and previous brands such as Porsche, Audi, GAC Ean and Polar Fox have also had a layout.

"increasing the power by increasing the charging voltage can reduce the heat generated by harnesses, connectors, etc." Junsheng New Energy Research Institute said that the power battery is like a cister. it stores electrical energy in the battery through a vehicle charger, distributes it to various components through distribution units, and satisfies the power supply voltage of different components through voltage conversion modules. with the high voltage of the platform, parts and components such as charging and voltage conversion also need to be upgraded to adapt to 800V or higher voltage.

CTOnews.com has learned that in the global market, Qunsheng Electronics has achieved mass production in the European market with some high-performance 800V high-voltage platform technology in the field of high-voltage fast charging, such as the 800V high-voltage platform technology provided earlier for Porsche's related models, including high-voltage charging booster, three-in-one integrated voltage converter and so on. In 2022, Junsheng Electronics accumulated about 9 billion yuan of new orders related to 800V high voltage platform.
