Are electric cars afraid of cold? How Skywell developed its "self-heating" physique

This winter is particularly cold. Various places have set records for the lowest temperatures of this century, and even Shanghai can see the spectacle of "water turning into ice". The battery life is "discounted", and the air conditioner is never turned on to save electricity... "cold-fearing" electric cars have also become a hot topic of concern. However, jokes are jokes, and low temperatures are like a huge "invisible killer" for any electronic appliance, so warm baby is still a standard feature of mobile phones in Northeast China.

For electric vehicles, low temperature environment will greatly affect the activity of batteries, and turning on the heater in winter is a rigid demand, so how to find the best balance between safety, comfort and performance is a difficult problem facing every electric vehicle. The 5+X high-end smart electric SUV Skywell ME7, which has attracted much attention in the market recently, is equipped with a leading battery pack four-season constant temperature system. Before it was launched, it experienced the extreme cold of minus 30 degrees in Yakeshi. With the triple "cold-proof" equipment of intelligent temperature control, rapid heating and energy management, it can easily fight against the severe cold.

The insulation material is five times more warm than thermal underwear

The most basic way to fight against low temperatures is to learn how to keep warm. The Skywell ME7 uses four layers of thermal insulation technology on the battery pack. The outer three layers use flexible thermal insulation materials to tightly surround the battery. The thermal conductivity is only 0.03 W/mK, and the warmth effect is about five times that of thermal underwear. The fourth layer is an intelligent thermal control fluid circulation insulation that is close to the battery, which can quickly heat up the battery.

The excellent heat preservation ability makes the Skywell ME7 perform well in the cold north. After a night of rest, the driving power performance of the vehicles of northern users is still strong in the morning.

Unique intelligent thermal control technology allows the battery core to heat up quickly

As users place higher demands on performance such as cruising range and charging speed, Skywell Auto, like other brands such as Tesla and BMW, adopts a four-season constant temperature system for battery packs with a high heat exchange coefficient and better temperature uniformity. Through intelligent liquid cooling and heating of the battery, the battery is always kept in good condition.

When the external temperature is lower than the minimum operating temperature of the power battery, the liquid preheating function is turned on. Each set of templates of the Skywell ME7 is preset with 2 temperature probes. With the unique intelligent thermal control fluid thermal management technology, the temperature of the module is monitored at all times, and the heating power is dynamically adjusted to ensure that each battery cell can be heated evenly. In the actual measurement of Skywell ME7 in a -20℃ environment, it only takes 30 minutes to heat the battery cell temperature from -10℃ to 8℃, allowing the vehicle power to recover quickly.

Efficient battery energy management, finding the best balance between comfort and performance

Under low temperature conditions, battery activity decreases. If the vehicle's output power is still the same as at normal temperature, it will not only damage the battery pack, but may even cause the vehicle to break down due to lack of power. Battery energy management is crucial.

The battery of the Skywell ME7 will first ensure power to the battery and low-voltage power supply components to prevent the situation where the vehicle cannot be started due to a dead battery; the second is the thermal management system including the air conditioning system and battery heating system; and then the vehicle's power system. The Skywell ME7 uses an efficient battery energy management system to improve the response efficiency of the entire vehicle system and find the best balance between comfort and performance.

With the development of battery technology and intelligent network technology, the "fear of cold" of electric vehicles has been greatly improved. The Skywell ME7 also has a remote vehicle control function, which can remotely turn on the air conditioning and seat heating ten minutes in advance, not only making the interior of the car warm and comfortable, but also heating the battery to the optimal temperature. In addition, you can also make an appointment for charging the Skywell ME7 through the Skywell APP, while enjoying cheaper off-peak electricity prices, so that the battery is at a higher temperature when you set off, and the vehicle performance and endurance are even better. The Skywell ME7 has more black technology ways to keep out the cold, waiting for you to unlock it yourself.
