2, before the asynchronous rear induction electric drive assembly technology status: 
In the Selis SF5 Free Expeditionary Edition, it uses a new “hump” extrovert drive technology solution, self-developed. The front 255 kWh-one asynchronous sensing electric drive assembly has been reserved, and 1 set of 150 kW three-in-one permanent magnet synchronous electric drive assembly developed with Huawei jointly developed.
Maximum output power 255 kW, the maximum speed of 16000 rpm, the oil-cooling heat-dissipating SEP200 three-in-one asynchronous sensing electric drive assembly is 93%. In the Sails SF5 free expeditionary version of the Chongqing, the SEP200 three-in-one asynchronous sensing electric drive assembly and the supporting electric control unit are also produced. In order to deal with high speed and large torque, the electron control system applies the same single tube IGBT package with Tesla.technology. The uniform IGBT will be encapsulated into a module through a single tube parallel package technology, and the power size adjustment can be achieved by the increase or decrease of single tube IGBT.
In the SF5 free expedition, the front asynchronous induction electric drive assembly, activates and outputs torque when the full load acceleration and the front and rear wheels. 
The red area is a close-up of Huawei DriveOne three-in-one after the Sails SF5 free expedition. The Sails SF5 Free Expedition is the first quantitative model of the first integrated Huawei three-in-one permanent magnet synchronous electric drive assembly.
The author noted that in the process of gently stepping on the “throttle” pedal slowly accelerates, the Sails SF5 free expedition only has the back Huawei DriveOne three-in-electric drive system output Torque (referred to in the red arrow).
During the “throttle” pedal full load acceleration, the two sets of electric drive assemblies before and after the four sets of electric drive assemblies before and after simultaneous output torque (referred to as the red arrow).
According to the field engineer, in the lowest point state in the power battery SOC value, the four-cylinder 1.5T engine and generator are powdered when power is generated, and the heat generation is in normal state (low speed or high speed). Driven, still have the ability to output torque at full time four-wheel drive when full load acceleration.
3, thermostatic liquid cooling power battery assembly technology status:
Sails SF5 free expedition is adapted to 1 set of square three-dimensional lithium battery based, load electricity 35 degrees Constant temperature liquid cooling battery system. Sails SF5 Freedom Expedition is this set of density power battery systems, adapting to its own research and development of “monitoring, alarm, explosion-proof, insulation, cooling” five-level safety management system.
In Chongqing’s Sails SF5 Freedom Expeditionary R & D Center, 1 set of three-in-one asynchronous sensing electric drive assembly and three-dimensional lithium battery constitute 1 complete The gantry drive system is sealed in water after energization. Sails SF5 Free Expeditionary Power Battery Case has a super IP67 physical protection level, motor + battery + electric control unit can be immersed in a 1M depth of water, continuous operation of 30 min, no leakage risk.
The prior to Sais SF5 broadcasts extreme thermal out-of-control expansion test in the world’s first public, and puts the whole vehicle in a very hot environment. There is no battery life, and the test time is far super national standard. Claim. 
The author has something to say:
Although the SF5 free expedition is configured with a straight four-cylinder 1.5T engine, it is always driven by EV mode while maintaining the vehicle NVH and EV models. Consistent. The maximum power generation power is 90 kW (rated 50 kW), enough to ensure that the vehicle is in a loss, directly for the electricity of the front and rear electric drive assembly frequently accelerated. The pre-preserved 255 kWh-one asynchronous sensing electric drive assembly, mostly used for passability of full load acceleration and maintaining complex road conditions; replacing the power consumption lower Huawei 150 kW three-in-one permanent magnet synchronous electric drive assembly, Many for low load power output and high-speed cruise, so that the Sails SF5 free expedition has become a model with more than 1,000 kilometers of comprehensively endless mileage and zero hundred acceleration.
In the case of some of the new forces and traditional cafetries, in the form of “噱噱”, advocating the EV model to reach a 1000-kilometer life-ranging mileage development strategy.蔚 来 ET7 released a solid-state battery version equipped with 150 degrees, which has achieved a limited range of 1,000 kilometers. However, it is important to note that 蔚 来 ET7 can’t be delivered immediately, but it is necessary to start in the first quarter of next year, and the solid battery version takes 2022 to four quarters.
Sails adheres to the “electric power-to-electric, powerless refueling” increased transition drive technology, with power battery active safety and electric four-wheel drive safety as design traction points, obtained super The development strategy of 1000 kilometers of life is more reasonable.
