BYD’s megawatt flash charging: 400 km range in 5 minutes. What’s the point of battery swapping now?
The issue of energy replenishment for new energy vehicles (NEVs) has always been one of the obstacles hindering their development. After all, the charging time for many NEVs often takes 30 minutes or more. During emergencies or holidays, queuing for charging remains a common sight. The reasons for these queues are twofold: insufficient charging infrastructure and excessively slow charging speeds! Recently, BYD unveiled its ultra e-Platform technology, achieving a charging power of 1 megawatt (1,000 kW)—the highest peak charging speed in mass-produced vehicles worldwide at 2 km per second. This sets a global benchmark for mass-produced EVs: a 5-minute flash charge delivers 400 km of range. Achieving “charging at gas-pump speed” requires simultaneous ultra-high voltage and ultra-high current charging. The newly unveiled ultra e-Platform represents the world’s first mass-produced passenger vehicle “Full-Domain 1000V High-Voltage Architecture,” upgrading battery, motor, power electronics, and air conditioning systems to 1000V – truly ushering EVs into the kilovolt era. BYD has also officially launched its “Flash Charging Battery,” establishing ultra-high-speed ion channels from cathode to anode. This innovation: Powered by ultra-high 1000V voltage and ultra-high 1000A current, the “Flash Charging Battery” achieves a world-leading 1 megawatt (1000kW) charging power for mass-produced vehicles, officially ushering in
Cost breakdown analysis of automotive wiring harness
Cost breakdown analysis of automotive wiring harness in China The highest cost in terms of proportion is the material cost, followed by labor cost. Chart 1: Direct material expenses have the highest proportion in total costs. (Zhejiang Commercial Securities Research Institute) From the perspective of the automotive industry, the main production materials for wire harness industry are wire, terminals, sheaths, sealing components, etc., involving materials such as copper, rubber, plastic, etc. The price is mainly determined by the market price of commodities such as copper, stone oil, natural rubber, and other chemical materials. According to the 2021 annual report of HuGuang Group, the direct material cost accounts for the highest proportion of the cost, reaching 76.64%. The automotive wiring harness industry is a typical labor-intensive industry, requiring a large number of workers to engage in operations such as inserting, wiring, wrapping, and rolling during the harness manufacturing process. Therefore, labor costs are relatively high in the wiring harness industry. According to HuGuang Group’s 2021 annual report, direct labor costs account for 13.43%.
