(1) European cars
① BMW. Earlier, the BMW Group revealed its strategic plan for electric vehicles. By 2025, it will provide 25 electric vehicle models, 12 of which are pure electric vehicle models. At present, BMW’s most popular electric vehicles in the market are i3 and i8 (hybrid models).
The dimensions (length, width, and height) of the BMW i3 are 3990mm, 175mm, and 1578mm, respectively, and the wheelbase is 2570mm. As shown in Figure 1, it uses a four-seater design and has a luggage compartment volume of 200L, which is suitable for urban travel. The pure electric model will be equipped with an information system called Connected Drive, which will provide information about charging stations near the location. The new car has three driving modes: comfortable, economic and super economic.
The BMW i3 pure electric version is the first mass-produced car whose body is mainly made of carbon fiber materials. The maximum output power of the i3 motor can reach 125kW. It is equipped with a rear-wheel drive system. The acceleration time from 0 to 100km/h is 7.2s, and the maximum speed can reach 150km/h. With a high-speed charger, 80% of the battery can be charged in just 1h.
In addition, the BMW i3 will also be equipped with an automatic navigation system to realize automatic driving functions. The entire system includes automatic braking and automatic parking systems. The car can also realize automatic lane changes when the vehicle speed is lower than 40km/h.
② Mercedes-Benz. The early pure electric vehicles of Mercedes-Benz were the micro smart series. In 2016, Mercedes-Benz released three pure electric versions-smart fortwo (see Figure 2), smart fortwo convertible and smart forour. The subsidiary Smart (Elf) Automobile Co., Ltd. develops and produces.
The three smart pure electric vehicles are driven by rear motors jointly developed by Mercedes-Benz and Renault, with a maximum output of 55kw, a torque peak of 130N·m, a built-in 17.6kw·h lithium battery, a maximum speed of 125km/h, and continuous driving. The mileage can reach 450km. 0~100km/h acceleration time is 11.5s, charging time (0~100%) is 6~7h.
Mercedes-Benz’s first pure electric passenger car is the Mercedes-Benz EQC (see Figure 3), which is a pure electric SUV. The EQC is driven by pure electric power, and the power system will consist of two motors and a lithium battery pack. Among them, the combined output power of the two motors is 300 kW, the peak torque is 730 N·m, and the battery pack energy is 79.2 kW·h. The 0~100km/h acceleration time of EQC does not exceed 5.1 s. Cycle, also known as the new European cycle test), the driving range under the standard is 415km. When using DC fast charging to charge the EQC, under the maximum rated power of 90 kW, the time required to charge from 10% to 80% of the power does not exceed 45 minutes.
③The public. On the eve of the 2016 Paris Motor Show, Volkswagen released its new compact pure electric I.D. concept car (see Figure 4). It is Volkswagen’s first compact model based on the Electric Modular (MEB) platform.
The ID concept car is the first model in the series of Volkswagen’s new electric car products. It adopts Volkswagen’s new design genes and has a high degree of recognition. The size of the new car is similar to that of the Volkswagen Golf. Energy blue decoration, while the roof is designed in black.
I.D. brings a feeling of spacious interior space by adopting Open Space design. The ID concept car also showcased Volkswagen’s fully automated driving technology. When the “ID cruise” mode (fully automated driving mode) is turned on, the ID’s multifunctional steering wheel will be placed under the dashboard. It is reported that Volkswagen plans to launch a fully automated driving in 2025. Model ID production version models. In addition, the official introduction I.D. also has the function of receiving express delivery when users are out.
ID is driven by a motor, with a maximum power of 125kW, and a follow-up driving range of 400~600km on a single charge. Its mass production model is planned to be officially released in 2019, and then officially put into production in 2020, and it is expected to be carried out in SAIC Volkswagen in the future. Domestically produced.
④ Renault. Renault’s early pure electric vehicle is a miniature pure electric vehicle Twizy (see Figure 5), and its body size (length, width and height) is 2337mm1191mm1461mm. There are two seats in the car in a longitudinal layout. The car is equipped with a motor with a maximum power of 15kW, and the maximum speed can reach 75km/h. This pure electric car only takes 3.5h to fully charge, and the new car has a driving range of up to 100km, which can meet the daily commuting needs of the city. .
Renault’s new energy vehicles have achieved a certain degree of development in the European market. There are currently four more mature pure electric vehicle models on sale (see Figure 6). Among them, Fenglang ZE was introduced to China in 2017, and Dongfeng Renault production.
Since March 2015, Renault has been improving ZOE pure electric vehicles. The ZOE currently on sale has a 22kW·h battery pack with a driving range of 241km and an actual operating distance of 145km. The new ZOE will use LG’s new battery and a smaller and more efficient motor, and the driving range will be increased to 400km.
At the 2016 Paris Motor Show, Renault officially released the new TREZOR concept car (see Figure 7). The TREZOR concept car can be seen as a continuation of the DeZir concept car launched by Renault in 2010, showing the Renault brand’s vision for future travel modes and future automobile manufacturing. The design concept adopts a number of new technologies. The Renault TREZOR concept car will adopt a completely independent driving mode, which can achieve independent driving functions without driver intervention. It will be powered by pure electric power and will be equipped with a new lithium battery pack from LG, and will have a maximum range of 402km. .
(2) Japanese cars
Japan’s outstanding performance in electric vehicles is Nissan (NISSAN). The Nissan Leaf (see Figure 8) is a five-door, five-seater hatchback powered by a stacked compact lithium-ion battery. It was listed on the European, American and Japanese markets at the end of 2010, and has been sold in China since 2011.
As one of the world’s most-selling pure electric vehicles, Nissan’s second-generation Leaf was launched in 2017. In addition to adopting a more technologically-sense design in appearance and interior, the new model also includes advanced autonomous driving, single-pedal operation, etc. new technology.
The Nissan Leaf uses a newly developed lithium battery pack whose performance is similar to that of an ordinary economic hatchback. The battery pack can support a motor with a maximum of 120 horsepower (about 88kW). The peak output torque of the motor matched by the Nissan Leaf is 280N· m. Leaf’s fast charge mode can replenish the battery pack’s power to 80% within 30 minutes, which greatly improves the status quo that the battery pack cannot be recharged quickly, but fast charging is only suitable for emergency needs. It still takes 8 hours to fully charge the battery. The owner can use the night Charge it.
