China International Automotive New Energy and Technology Exhibition opened today at the Beijing National Convention Center. In this exhibition, Shanghai Chai Ri Electric Co., Ltd. in the industry first introduced multi-function flexible battery pack PACK product stand in front of a crowded. Industry experts said that this adopted a number of "pioneering" technology, not only enhance the safety of new energy electric vehicle battery pack in the course of the work of safety and reliability, but also for the battery (group) PACK standardization, high-volume, fast production Provide possible invention patents, or will set off a new energy electric car battery revolution. At present, lithium battery packs are the core components of new energy electric vehicles (in the industry, battery packs). They guarantee the voltage and capacity required for vehicle operation control through complicated series, parallel or hybrid connections. A battery PACK installed dozens of batteries, the power line and communications secondary line connection workload is quite large, and because of long-term operation of the vehicle, it is likely to cause loose bolts, lead fatigue damage caused by a variety of failures. The safety, economy and ease of maintenance of new energy vehicles in the power supply chain have become major obstacles in the large-scale promotion worldwide. There is an increasing demand in the industry for the demand for more cost-effective power supply complete sets of technology products. Chasing Japan Electric Power Systems Division Marketing Director Li Hengjie told reporters that the pursuit of Japan Electric at the end of 2012 to develop the world's first patented product multi-functional flexible connecting battery PACK, changing the traditional battery PACK and battery management system (BMS) between the wiring harness Connection method, the use of flexible pin cap snap connection, and the integrated concept of "sandwich" sandwich structure. The internal power and communication will be strong, weak isolation design, the battery pack power big current and battery management system sampling current separation, effectively avoiding the mutual electromagnetic interference, and the first PCB circuit board for PACK battery cell data collection. Compared with the prior art, the product has reliable battery signal detection method and remarkable improvement in electromagnetic interference and signal detection failure suppression. As the product uses advanced prefabricated concept, which greatly reduces the battery pack group production process of manual wiring review workload, battery pack production line operations and standardization of production, for all models have excellent Adaptability. Dongfeng Motor Company in the field of battery plant test shows that the new battery PACK can improve battery assembly efficiency of more than 10 times, battery maintenance and replacement efficiency increased more than 5 times, a substantial saving in production costs and shorten because of maintenance and maintenance Spent time, which can greatly save the cost of social promotion of new energy electric vehicles. This multi-function flexible connecting battery PACK passed the continuous reliability test of the national power battery testing and testing center in February this year. In May this year, the new battery PACK passed vehicle functional verification and reliability verification at Dongfeng Xiangyang Test Drive, Asia's largest car test site: at a time when the vehicle passed a large number of deceleration belts at a speed of 50 kilometers an hour (commonly known as "washboard Road "), the vehicle's vertical acceleration of 5G or more, in the case of greatly exceeded the normal test conditions, the power and communication is completely normal. From May till now, the product runs a mileage of 200,000 km on the Dongfeng Electric Hybrid Electric Vehicle and is still stable and reliable. In late June, dozens of experts from the National Automotive Standardization Technical Committee of Electrified Vehicles Sub-Technical Committee came to the electric power production base in Chaoyang to make an on-the-spot investigation on the multi-functional flexible connecting battery PACK and spoke highly of its advanced nature and application prospect.
