March 28, Si Wei’s new car E10X was officially listed, and the new car launched 7 models, and the subsidies were priced at 3.99-.759 million yuan. Siyi is a new joint venture of Jianghuai and the public, Siwei E10X as its first A00-level electric model, born from a German intersection gene.
Siwei E10X positioning A00-level electric vehicle, using the Italian Turin Design Center carefully created a new design language, using two-color fashion body design, more dynamic and dynamic. Siyu E10X body size length is 3650mm * 1670mm * 1540mm, the wheelbase is 2390mm, the highly quality is 1 meal, the vehicle size is good than the current popular macro MINI EV space has a good advantage.
The liquid crystal display of the driver is taken into a style of driving auxiliary area + energy output / recycling area. The driving assisted function area of the left side is used to prompt the driver’s intelligent fixed speed cruise function to open the actual state; the energy output / recycled function area on the right side, mainly displays data such as battery life and power output.
Sihao E10X electric car is divided into three sets of row models, standards (maximum speed 102 km / h), Economic (maximum speed 102 km / h) and long battery life (60 km / h of speeds).
Sihao E10X adaptive electric drive system largest output km 45 kW (endless mileage 300 km) and 30 kW (endless mileage 150 km and 200 km). It should be noted that the two different power electrical drive systems, from the manufacturer of Sihao E10x, Jiangqi Group (that is, Jianghuai New Energy) self-developed and mass production.
This “4-in-1” electric drive system integrates the speed reducer, drive motor, electronics, and PDU (distribution box). The maximum speed of 12,000 rpm and the maximum output power of 45 kW were verified by the maximum output power of 45 kW.
“3-in-one” electric drive system, Jiangqi Group (Jianghuai New Energy) Research Institute, is used for the first time for the whole vehicle adaptation, The PDU (distribution box) of the category of high voltage control system is integrated with the electric drive control system, which can be modular integration with different levels of “2-in 1” high-pressure electricity system (DCDC and OBC). 
In view of the maturity and growth of China’s new energy industry chain in 2021, the cost advantages and reliability of DCDC (inverters) and OBC (chargers) manufactured by third parties continued to increase. With core technology R & D capabilities, more human resources and R & D costs can be used in high efficiency of electric drive systems, and mutorize modular integration with DCDC and OBC provided by third parties.
The figure above shows the status of the 200 km E10X power battery assembly structure. In fact, the 100-kilometer and 200 kilometers of E10X power battery assembly and technical architecture are almost the same, based on the 32135 cylindrical phosphate cells provided by Volkswagen, the module and battery provided by the walker power The total (including BMS).

The above picture shows the status of the 300 km E10X power battery assembly structure. E10X’s 150 km and 200 km diversified power cells are made of 32135 cylindrical phosphate lithium iron cores, and 300 kilometers of power batteries are manufactured based on 2265146 square phosphate lithium iron-core.
Since the three different endurance mileage versions are completely consistent, this means that the specifications of the power battery assembly are exactly the same, so it is greater by the monomer density. 2265146 Square phosphate battery, instead of 32135 cylindrical phosphate lithium iron core. 2265146 The square phosphate lithium battery core still has Volkswagen, and the power battery has always become a witchen power manufacturing (including BMS).
The picture above is a close-up of several different specifications of electric cores disclosed in Jiangqi Group (Jianghuai New Energy) Research Institute.

2 new specifications of new specifications of phosphoric acid introduced upon E10X The power battery assembly of the iron lithium battery and the construction of a very demanding safety test. In particular, after preheating the power battery assembly (simulating the actual vehicle condition), collision, impact and acupuncture test do not have fire and combustion and ensure all samples are completed. The safety of the ferrous iron-resistant iron core is high, and the thermal battery assembly is combined with the thermal dispersion and energy export of the power battery assembly, and the power battery system of the E10X electric vehicle adopts a passive wind cooling solution.
It should be noted that the current Tesla Model S \ x \ 3 \ y, both 21700 cylindrical three-dimensional lithium battery and power battery composed of square phosphate lithium iron cells provided by Ningde Times system. However, the monomer density applied by E10X is 32135 cylindrical phosphate cells (less), inevitably leads to energy density and volume.The density is correspondingly improved.
In terms of battery life, Siyu E10xNEDC battery life is 150 km version of the battery loader is 15 degrees, and NEDC is 200 kilometers of version of the battery. The battery is charged to 19.7 degrees. NEDC battery life is 30.8 degrees of electricity. The ratio is 3.99-7.59 million yuan, the endless mileage is 150-302 kilometers, and the Sihao E10x explored the huge incremental market for low-speed electric vehicles on the one hand, and the 300-kilometer home entry electric car just needs the market.
The author has something to say:
The research and development concept of Sihao E10X is very clear, that is, a young electric vehicle that manufactures a safe premise to meet the needs of different market needs. Although the E10x electric vehicle power battery does not have liquid cooling technology, the introduction of cylindrical density is more density, and the introduction of the square phosphate battery, and the configuration of many auxiliary safety architectures, or the high temperature environment and DC fast charge exists. Security risks.
The E10X configures a set of “4-in-one 1” electric drive system, and is composed of 2 power battery systems based on 32135 cylindrical phosphate cells, 1 2265146 square phosphate lithium iron battery River Automobile Group (Jianghuai New Energy) Weaner Production Type Brand New Electric Driving and Power Battery Technology Solution.
The follow-up will be on the multi-models of the Jiangqi Group (Jianghuai New Energy) in subsequent listed, and the adapted electrical drive technology and power battery thermal management control strategies and judgments.
