With its comfortable driving experience and superior intelligent configuration, the Deep Blue S7 has received widespread attention from the industry and the consumer market. The Deep Blue S7 equipped with "Super Range Extender" technology brings consumers a super driving experience with its outstanding performance of "pure electric drive, long battery life, and low energy consumption". Before the Deep Blue S7 is about to be launched, enjoy the leading technology and product charm of the Deep Blue S7 "Super Range Extender".
Deep Blue S7 range extension technology adopts four core technical strategies: NVH intelligent balance strategy, engine non-inductive start strategy, low-torsional vibration structure design under full working conditions, and howling frequency conversion active control technology, bringing users quiet, smooth, shockless and senseless driving enjoyment under all working conditions. Adopt NVH intelligent balance strategy to optimize the NVH performance of the range extender itself to the greatest extent, thereby improving the NVH of the whole vehicle and bringing a quiet experience; Using the engine non-sensory start strategy, it can realize silent start and non-inductive power generation when the engine starts and stops, bringing the same smooth and senseless driving pleasure enjoyment as pure electric driving; The design of low-torsional vibration structure under full working conditions brings more than 50% improvement to the vibration isolation rate of the whole vehicle and maximizes the shock absorption effect; Using howling frequency conversion active control technology, accurately control the switching frequency of the range extender generator, reduce the vibration noise caused by high-frequency vibration, and further optimize the quiet and senseless experience of the whole vehicle.
The navy S7 has a cruising range of 1120km in extended range mode, which can realize long-distance travel needs. Integrating the advantages of pure electric and fuel, it not only has ultra-low vehicle costs, but also solves various problems such as mileage anxiety and inconvenience of energy replenishment of pure electric vehicles. The high-efficiency all-round range extender brings the highest efficiency of 96% to the generator, and the economy and power are all in one.
Under CLTC conditions, Deep Blue S7 has an ultra-long pure electric cruising range of 200km, which not only meets the needs of environmental protection and low carbon, daily commuting, but also greatly reduces the cost of using the car, which can achieve one month without refueling and one week without charging.
Based on dynamic design of howling frequency conversion active control, through NVH intelligent balance strategy, engine non-inductive start strategy and low torsional vibration structure design under all working conditions. It brings the perfect balance of NVH, power and economy. From electric drive to control, from control to riding, the range extender in driving has no sense of start and stop, hidden sound operation, maintaining a pure electric driving experience and quiet space, whether it is high speed or low speed, it can bring users a quiet and comfortable driving experience, and fully realize the global senseless operation of Deep Blue S7.

NVH intelligent balance strategy: double-layer software architecture balance algorithm design and fine calibration of all working conditions - precise engine speed torque control technology, harmonic injection technology (full speed (0-5000), full torque coverage) double-layer software architecture balance algorithm controls the operating conditions of the range extender through the vehicle software to ensure the optimal working state of the range extender and reduce NVH; At the same time, under the selected working conditions, by optimizing the range extender engine and generator software, the range extender body NVH optimization harmonic injection technology is guaranteed: when the generator speed is 800-2000+rpm, the whistling of the generator is perfectly solved, and the range extender generator is insensible. And achieve full working condition coverage (full speed (0-5000), full torque coverage)
Low torsional vibration structure design under full working conditions: S7 adopts a single-mass flywheel torsion shock absorber, the vibration isolation rate is increased by more than 50%, and the torsional shock absorption structure is added between the range extender and the generator, and the single-mass flywheel torsion shock absorber used in S7 increases the vibration isolation rate by more than 50%, realizing torque reduction, shock absorption, anti-slip, torque limiting, abnormal torque processing functions 3) Engine non-sensory start strategy: for different working conditions, the output power demand is accurately optimized and controlled, so as to achieve non-inductive start engine starting timing 1. Movement, during driving "Hidden sound" start engine 2, static, maintain the premise of power to provide pure electric driving, the engine stop "hidden sound" engine starting process is fast, crisp, undetected. Mainly through dragging, fuel injection, torque coordination, mode rapid switching idle power generation according to the vehicle power consumption intelligent adjustment, air conditioning turned on, hidden sound compensation vehicle driving power generation intelligent identification of the current power state, always optimize the best efficiency, hidden sound power generation, undetected, pure electric driving intelligent environmental analysis power generation high temperature, plateau, low temperature, automatic adjustment of power generation power target, such as normal temperature plain
Howling frequency conversion active control technology: accurately control the range extender generator IGBT switching frequency, realize the frequency conversion control of the switching frequency, realize the optimal howling under each working condition, accurate engine speed, torque control IGBT switching frequency affects the speed control of the generator, and then affects the engine speed fluctuation, the engine speed is stable in the high efficiency area IGBT front motor fixed frequency management control accurately calibrates the generator switching frequency: 10kHz (taking into account NVH & temperature rise & power generation efficiency)
Ten years of grinding a sword, is to bring users the best product experience. Under CLTC conditions, the Deep Blue S7 has an ultra-long pure electric cruising range of 200km, which not only meets the needs of environmental protection and low carbon, daily commuting, but also greatly reduces the cost of vehicles. Longer 0 fuel travel distance - no refueling in January Lower charging frequency - no charging for a week
The Deep Blue S7 has a cruising range of 1120km, which can realize long-distance travel needs, no need to find charging stations along the way, refuel and go. Integrating the advantages of pure electric and fuel, it not only has ultra-low vehicle costs, but also solves various problems such as mileage anxiety and inconvenience of energy replenishment of pure electric vehicles. At the same time, through technological innovations such as the high compression ratio and deep Atkinson cycle, the maximum efficiency of the generator is 96%, and under CLTC conditions, 1L oil power generation can be achieved by about 3.3 degrees. In the feed-fed state, the Deep Blue S7 still has a fuel consumption performance as low as 4.95L/100km, reaching the industry-leading level.
