On June 15th, prior to the launch of the Deep Blue S7, Deep Blue Automobile held a special analysis event for the extended-range technology of the Deep Blue S7. The Deep Blue S7 has garnered widespread attention from the industry and consumer market due to its comfortable driving experience and superior intelligent configuration. Its "super extended-range" technology, with its excellent performance of "pure electric drive, long endurance, and low energy consumption," has brought consumers an ultra-sensory driving experience.

Before the upcoming market launch of the Deep Blue S7, let's appreciate the leading technology and product charm of its "super extended-range." In the slalom, slippery handling stability road, and comprehensive evaluation road, the extended-range version of the Deep Blue S7 demonstrated its superb chassis and performance tuning. Additionally, the tires of the extended-range version of the Deep Blue S7 have been optimized more than 10 times beyond industry standards, with meticulous polishing of over 100 detailed plans. It is matched with a rare 21-inch sports wheel and high-performance sports tires in its class, giving the vehicle ample grip in corners and a near 50:50 front-to-rear axle load ratio, which also provides it with a higher handling limit.

Extended-range technology is essentially a series hybrid technology, characterized by the internal combustion engine not directly participating in wheel drive at any time, with a very singular responsibility of generating electricity. This mode of operation simplifies the work of the internal combustion engine, thus avoiding the significant deterioration of combustion efficiency in complex working conditions. The engine spends more of its working time in a higher efficiency range, thereby improving the overall fuel efficiency of the vehicle.

Moreover, since the internal combustion engine does not drive the wheels but is directly driven by the electric motor, many vibrations and noises that occur in the internal combustion engine and transmission process are also very well controlled, which is another added advantage of extended-range electric vehicles.

The above describes the main body of traditional extended-range electric technology, but different brands, due to varying technical strengths, will also have some differences in the effects achieved, such as the efficiency of the internal combustion engine, the efficiency of the generator, and whether the overall power system design is reasonable, etc. Today, let's take a look at how the super extended-range technology equipped in the soon-to-be-launched Deep Blue S7 is implemented.

The extended-range technology of the Deep Blue S7 uses an extended-range generator that includes decades of engine self-research experience from Changan. It adopts a high compression ratio Atkinson cycle with a 78% slot fill rate, resulting in higher power density. Approximately 3.3kWh of electricity can be generated from 1L of fuel, and the generator has a peak efficiency of 96%. The combination of these technologies ensures that even when the Deep Blue S7 is in a power-feeding state, it still has a low fuel consumption of 4.95L/100km. In extended-range mode, the driving range can reach 1120km, meeting users' long-distance travel needs. It offers the ultra-low operating costs of an electric vehicle without any range anxiety, capturing both economy and power performance.The range-extending system of the vehicle employs four technological strategies: NVH intelligent balance strategy, engine imperceptible start strategy, full-scenario low-torque vibration structure design, and howl frequency conversion active control technology. With the support of these technologies, the vehicle can provide a quiet, smooth, and vibration-free driving experience akin to that of a pure electric vehicle.

The Deep Blue S7 is equipped with the EPA1 all-electric digital platform, which is the first self-developed all-electric platform by Deep Blue. The electric drive efficiency can reach 95%, and it features the IBC digital battery management system. Through two categories of digital pre-control management technology clusters and seven categories of digital temperature control management technology clusters, it ensures that the probability of thermal runaway of the battery cells and the assembly is close to zero. Even if a single battery cell has exhibited signs of thermal runaway, it can effectively prevent the thermal runaway of the entire pack.

The battery pack of the Deep Blue S7 features the world's first micro-nucleus high-frequency pulse heating function, which effectively solves the issue of performance degradation of the battery at extremely low temperatures, leading to a decrease in power. The battery pack has an ultra-fast heating capability that can raise the battery temperature by 20°C in just 5 minutes, allowing users to enjoy a smooth driving experience even in extremely low temperatures of -30°C.

Additionally, the Deep Blue S7 range-extender model is equipped with a front MacPherson and rear multi-link independent suspension system, providing strong lateral support for the vehicle during cornering. After being tuned by top industry masters, the Deep Blue S7 also combines both sportiness and comfort.

It is worth mentioning that the Deep Blue S7 is born from the industry-first all-electric digital platform by Deep Blue, the EPA1. This platform has four major technological characteristics: high efficiency, high performance, high intelligence, and high safety. It is compatible with various power forms such as pure electric, range-extender, and hydrogen electric, meeting users' multi-scenario electric travel needs.
