Previously, the new energy intelligence analysis network was technically stateful for the Great Wall’s first mass production. Try two manuscripts. In the “fast comment: Standard of the three-yuan lithium battery liquid heat management system” Good Cat “, in the article, the European Cat, which is an Ou Wai Cat, which is equipped with a three-dimensional lithium battery system. In the “fast comment: the first Great Wall Eu” in the Great Wall Euless Cat with Power Battery Liquid Heat Management System, a simple test is made to Eule Good Cats.
Now, the new energy intelligence analysis network will introduce self-funded car long test series for Great Wall European Cat (Iron Battery Version) electric car, carrying phosphoric acid Type platform, electric drive technology, power battery thermal management (charge and discharge) control strategy, winter and summer endurance mileage, and vehicle reliability.
Long-width high 4235x1825x1596mm, axial distance 2650mm; drive motor maximum output power 105 kW, Euler good cat electric vehicle, depending on the configuration and price, total 5 models in stock. Among them, the price of 10.39 \ 11.39 \ 12.39 million models of the Euler Tmin is equipped with the lithium iron phosphate battery system (provided by the Jiangsu era), the NEDC endless mileage is 401 kilometers; the price of 13.39 \ 14.39 million models of Euler Tmall configuration Sany-lithium battery system (Honeycomb technology), NEDC battery life is 501 km. Regardless of the use of iron batteries or three-yuan lithium batteries, the models are fully consistent.
After lifting this Euler Cat (Iron Bell) for Long Test, you can clean the front side border (blue) Arrow refers to the Power Battery Front Pipe Panel (White Arrow “and Power Single Battery Front Protection Beams (Green Arrows).

The front (radiator) frame of the ELIL is constructed from the composite material, which is integrated with a variable gas grille.
A variable gas grille technology earliest uses and introduces Chinese market in General Buick and Chevrolet. In the overall travel of the external climate and engine temperature, Automatic opening and closing grille to ensure that heat in the power cabin is in an optimal state, or reduces fuel consumption or reduces wind resistance. Introducing a variable gas grille technology in new energy vehicles, is also used to maintain power compilation Temperature balance, reduce power consumption and wind resistance.
OLE Cat is loaded 1 unit by United Automotive Electronics Co., Ltd.The maximum output power is provided 105 kW, the maximum output torque is 210 Nm, the maximum speed of 16000 rpm, the permanent magnet synchronous drive motor.
From the technical specification, the “3-in-one 1” electric drive assembly made of the permanent magnet synchronous drive motor provided by “Unit” is equipped with “Unit”, and the maximum speed is 16,000 rpm. It is also the highest speed of domestic civil new energy vehicles. However, this “3-in-1” electric drive assembly uses oil-cooling heat and flat line winding technology, and it is not certain.
The picture above shows the rear end of the OLE good cat steel full frame, fixed “3 in 1” electric drive assembly suspension mechanism assembly close-up .
The suspension support portion associated with the sub-frame is composed of aluminum material; the bracket associated with the “3-in-1” electrical drive assembly is composed of steel.

Great Wall Euler Good cat mounted electric air conditioning compressor is provided by BYD, model BC34. The currently known BC series electric air conditioner compressor is divided into 28 Series and 36 Series, and this Great Wall to BYD purchased BC34 series electric air conditioner compressors are a new series.

The post-suspension of the Ou La hooks adopts a standard torque beam semi-independent structure, in order to reduce the driver noise installed 1 set of rear guard.
The Great Wall is equipped with a complete power battery protection measures for El., The front-end interface guard and the protection beam can effectively avoid the safety accidents caused by collision during the driving.
This Ou La Tmall electric vehicle used for long tests, is provided by the lithium iron phosphate battery assembly by “lowering the age”, loaded electricity 47.8 degrees, 364.8 volt voltage platform. Ou Wan Cat is also an electric vehicle with a gas battery thermal management control technology with high temperature heat dissipation and low temperature preheating function.
Adaptation of the Sanyi Cat NEDC endless mileage of the three-yuan lithium battery system provided by “Honeycomb Technology” is 501 kilometers, loaded power is 59.1 degree electricity, voltage platform 388.8 Volt. 
Whether loading a lithium iron phosphate battery or a three-yuan lithium battery, the battery voltage platform is 360-380 volts, there is no 400 volts, which means to improve charging. Efficiency, it can only be achieved with an improvement of current.
The power battery assembly provided by the Jiangsu era is in line with IP67 protection standards, and the protective coating of soft material composed in front of the whole aluminum housing, with the lower end of the whole aluminum housing. To heat insulation and impact. Located on the front end of the power battery, a thermal management cycle line is arranged into and out of water, high voltage cable and BMS communication cable.

In order to reduce the safety problem caused by thermal battery thermal loss, Eu-Care cat is configured with Ora-Care Bee Cloud Battery Doctor function. That is, the power battery is under the monitoring of BMS, the battery, electrical connection, electrical insulation, and battery pack safety real-time detection. Once the source of the source automatic battery is expected, the warning is immediately issued, and the passengers are left to the passengers at least 5 minutes (the latest in 2020).Home mandatory standards).
The author has something to say:
For Eua good cat electric vehicles with a self-weight 1.51 tons, the adarable lithium iron phosphate battery is inevitable in winter, but in the summer high temperature environment The safety is relatively high; the NEDC endless mileage is 401 kilometers, the loader is 47.8 degrees, at the maximum output power of 105 kW, the highest speed 16000 rpm, “3-in-one 1” electric drive system, the real car environment The comprehensive power consumption of 100 kilometers can be controlled around 14 degrees. Of course, as the first integrated liquid-cooled power battery thermal management control system of the Great Wall, the Eli Cat (iron battery version), the charge and discharge efficiency of the 364.8 volt voltage platform is worth sustaining.
New Energy Intelligence Analysis Network will continue to update Eule Good Cat core technology, daily use, and evaluation manuscripts of the vehicle reliability.
