According to Tianyancha‘s official website, Seres Automotive Co., Ltd. has recently been granted a patent titled “A battery pack device for detaching an electric vehicle battery pack in a crash scenario, and electric vehicle.” This patent pertains to the technical field of electric vehicle accessories. Its core innovation lies in: when a vehicle is involved in a collision, it can automatically trigger the battery pack to separate from the vehicle body, thereby effectively enhancing occupant safety. Patent Information According to the patent’s abstract, the device employs a precision structure in which front and rear support assemblies work in coordination with an electric push rod. Protruding columns are installed on the front and rear sides of the battery pack’s lower shell. Support sleeves are installed at both ends of the end plate of the rear support assembly, which are plugged into the corresponding protruding columns. At the front end, a second electric push rod drives a guide plate and a rectangular rod to precisely control the locking and release of the protruding columns. When the vehicle is involved in a collision, the device automatically executes the battery pack detachment procedure to separate the battery pack from the vehicle body, fundamentally reducing the safety risk of thermal runaway caused by battery pack extrusion and deformation after the crash. Patent Information It is worth noting that Seres had already made ongoing investments in the field of battery safety. As early as October 2025, Seres applied for a patent titled “A vehicle control method, device and vehicle.“ This patent is capable of adjusting the vehicle’s attitude based on collision signals or battery pack thermal runaway signals and executing a battery pack discarding operation. The recent official grant of this new patent represents another step forward in Seres’ development of passive safety technology for electric vehicles. AITO M8 EV Battery Pack Test Since the start of 2026, Seres’ market performance has shown a trend of “rising sales volume but declining profits.” Production and sales data show that from January to April, the company’s cumulative sales of new energy vehicles reached 111,632 units, a year-on-year increase of 29.74%, of which the Wenjie brand accounted for approximately 98,741 units, or 88.45% of the total. However, the company is facing pressure on the profitability side. In the first quarter of 2026, the company’s revenue reached RMB 25.75 billion, a year-on-year increase of 34.5% but a 52.78% decline quarter-on-quarter; non-recurring net profit fell sharply by 73.87% year-on-year to RMB 1.03 billion, while the gross margin declined 2.4% quarter-on-quarter. In addition, net cash flow from operating activities stood at -RMB 20.95 billion, with the net outflow more than doubling compared with the same period last year. Overall, Seres continues to maintain a trajectory of scale expansion, but it is facing the challenge of “high growth, low profitability, and tight cash flow.”
