"Range anxiety" is undoubtedly one of the most topical hot words in the new energy vehicle industry. Almost every electric vehicle owner, especially in the cold winter, has been worried about the lack of power and the shrinking range, which has become a common concern among the electric vehicle community. Especially in winter, they are often tormented by shrinking range, or when faced with certain long-distance requirements, "range anxiety" is often amplified. "Range reduction" in cold weather has almost become a label that is difficult to get rid of new energy vehicles, and it has become a key word for its "attraction" criticism several times. Here, Dongfeng Nissan ARIYA breaks this stereotype for consumers with its excellent winter endurance performance, and perfectly integrates technology and comfort.
The battery, as the heart of an electric vehicle, will be affected to a certain extent at low temperatures. The cold environment increases the internal resistance of the battery, resulting in a decrease in discharge efficiency. In addition, in order to drive comfortably, car owners often need to use air conditioners, heaters and other large power consumers, which further reduces the effective use time of the battery. So, how does Dongfeng Nissan ARIYA stand out in such an environment?
To achieve excellent battery life, it is actually the result of the complementarity of the battery, motor, and electronic control. The battery is the basis for determining the range of the whole tram, and the motor and electronic control are the key to determine whether it can play the maximum value. ARIYA is equipped with a high-density liquid lithium battery of up to 90kWh in a limited space through a double-layer stacked module, bringing precise and long battery life.
In terms of motors, the permanent magnet synchronous motor and the AC asynchronous motor are creatively combined to complement each other's strengths and weaknesses to obtain an electrically excited synchronous motor with both high performance and low energy consumption, which realizes synchronous energy recovery of the front and rear wheels, maximizes efficiency, and brings more battery life. The electronic control of 1/10000 second ultra-high-precision motor torque control allows the power battery to work in the best state and improve the efficiency and reliability of the battery.
Today, I will focus on "battery" for you. First of all, Nissan's latest self-developed ARIYA all-condition battery precision management system, this system is different from the ordinary battery management system, it has strong real-time monitoring capabilities. Specifically, it can detect and analyze more than 200 parameters of the battery in real time. It monitors the various working states of the battery in real time, such as the voltage, current, and temperature of the battery. And adjust the working state of the battery according to different situations. It's like a doctor who constantly does a physical examination of the battery to make sure it is always in optimal health. It allows the battery to maintain optimal charging and discharging power in both regular high and low temperature environments, and it ensures stable operation of the battery even under multiple consecutive fast charges. No matter where or what the weather is, this management system ensures the best performance of the battery.
ARIYA is also equipped with an integrated Wet & Dry Thermal Management System, which is based on a "Wet & Dry Separation" architecture, which ensures that the battery runs in a safer state. At the same time, its intelligent thermal management system intelligently adjusts to the external temperature to keep the battery running in an ideal temperature range.
Let's talk about winter. As we all know, it is cold in winter, and the performance of the battery may be affected. From the perspective of humanized care, ARIYA gives full play to the excellent air conditioning heating performance, and realizes rapid air conditioning heating with the help of PTC heater in the circuit of ARIYA battery temperature control system, so as to meet the needs of users for heating in the car in winter.
Of course, everything is just based on data, isn't it just a "pie" for users. ARIYA has demonstrated its true performance in practice. In the authoritative test of the China Automotive Center, ARIYA successfully passed a temperature shock design test, and the standard of this test is as high as four times the national standard! According to the relevant national regulations, this temperature test should be carried out between -40°C and 60°C. But you know what? ARIYA does more than that. It further extends the range of high-temperature testing to more than 60°C. This means that whether it is in the northernmost part of the mainland, Mohe, or in the southernmost part of the Turpan Flaming Mountain, ARIYA can deal with that extreme temperature difference.
Not only that, unlike the 5 alternating hot and cold tests stipulated in the national standard, ARIYA has actually undergone up to 20 hot and cold cycle tests. After all these rigorous tests, the battery pack is still functioning properly and in perfect condition. And there are no leaks, fires, explosions and other dangerous phenomena, and no damage or cracks have been found in the internal structure of the battery.
Whether it is the era of fuel vehicles or the era of intelligent electric vehicles, for a means of transportation, aside from the attributes of consumer goods, its value, safety and reliability are still the most important needs of consumers for travel tools, with the continuous development and maturity of the market, these needs will not only not be outdated, but will be more valued by the mainstream market.
Dongfeng Nissan's successful electrification experience essentially captures such consumer values, whether it is the LEAF more than 10 years ago or today's ARIYA, it has always demanded itself with high standards in terms of quality and safety. Therefore, it has core competitiveness in the mainstream market and has always been a shining presence in the market.
