易车讯 Recently, we learned from the official channels of SAIC-GM-Wuling that after Wuling Hongguang MINI EV announced the appearance, the official interior image, and the pre-sale, its safety details have It has been revealed that although it is an electric car with pre-sales of 2.98-38.8 million yuan, it still pays more attention to shaping the safety level. It is understood that Wuling Hongguang MINI EV will improve the body strength and power battery safety.

In terms of vehicle safety, it is understood that the safety of Hongguang MINI electric vehicles fully meets the requirements of national automobile safety regulations. Its body structure is jointly developed with the team of safety collision experts of Hunan University. , The passenger compartment and battery compartment adopt cage-type and frame-type high-strength steel frames respectively, which can meet the high-dimensional safety protection requirements for passengers and batteries while achieving lightweight.

The body side wall, battery periphery and the main stress areas of the front and rear of the cabin are strengthened, and the proportion of high-strength steel in the entire body is more than 57%. Realistic roads with more complex environments can also effectively escort users. In addition, the Hongguang MINI electric vehicle has undergone 44 rigorous vehicle-level crash tests and has performed well in the same level of frontal and rear collision tests, providing a solid safety guard for the occupants.

For the temperature management and battery life of the power battery, it is equipped with low-temperature pre-heating charging technology and battery insulation function, which can pre-heat the battery under low-temperature charging and keep the battery pack temperature at 15 At -20℃, it can keep warm for up to 24 hours under charging. Compared with other models without heat preservation, the power performance is increased by 50%, and the overall cruising range is increased by 10%, effectively solving the problem of winter cruising discounts.

Regarding the safety of electric vehicles that everyone is concerned about, one of the causes of frequent spontaneous combustion is that the power battery is overcharged and over-discharged, subjected to acupuncture, squeezing, etc., which causes thermal runaway. In this regard, Hongguang MINI EV can monitor the status of the three power sources in real time through the mobile phone APP. The BMS intelligent battery management system equipped with the new car also closely monitors the battery working status around the clock. When a situation occurs, the battery will be forced to protect and improve battery safety.

In addition, the power battery of the car has experienced 16 rigorous safety test items such as temperature, short circuit, squeeze, fire, sea water immersion, and simulated collision. The battery heating device is dry for 10 hours without exception, and has dust and water resistance. Up to IP68 level, it is guaranteed in terms of charging and car safety.

In terms of appearance, the overall shape of Hongguang MINI EV adopts the "cut-edge geometry" design technique, which has sharp edges and corners without losing affinity, full of three-dimensional imagery and dynamic beauty. The straight and slightly "curved" shape not only helps expand more space in the car, but also makes the car more agile and interesting.

For the interior, the new car’s interior adopts a dark color scheme, and adds blue new energy elements to the air-conditioning control area and seats to increase the overall fashion. At the same time, the console has a straight line, with rounded rectangular instruments placed on it, and a knob at the bottom to shift gears, and equipped with electric windows, etc. The multiple storage grids in the car are also convenient for a family to use.

In terms of power, Hongguang MINI EV is divided into two versions with a range of 120km and 170km. It is equipped with a permanent magnet synchronous motor. The maximum power is 20kW, the maximum torque is 85Nm, and the power system is the same. The maximum speed is 100km/h and the power consumption is 16kWh/100km. . Depending on the endurance, the energy density of the battery system is different. The battery energy density of the 120km model is 100Wh/kg, and the battery energy density of the 170km model is 110Wh/kg.
