With the increasing market share of new energy vehicles, the choice to buy new energy vehicles has become a major trend for consumers to buy cars, and consumers' pain points for new energy vehicles are becoming more and more clear, and the two biggest concerns are nothing more than mileage and car safety.
However, there is a manufacturer that is born with its own safety attributes, while having a hundred years of car manufacturing experience and profound technical accumulation, it is Cadillac. Cadillac's first pure electric medium and large SUV, LYRIQ, is known for its technology, innovation and safety, and dispels consumers' car concerns one by one.
What is the "black" technology of the battery that is still reliable in winter?
"Winter electric vehicle mileage is short, power loss is fast, air conditioning is turned on more worse" these are common problems of electric vehicles in winter, of which shorter mileage is a key issue for users.
A major factor affecting the winter endurance of electric vehicles, we have to mention the thermal management technology of electric vehicles. Cadillac LYRIQ's Aoteneng pure electric platform opens up a new idea in the thermal management system, which combines multiple safety technologies and guarantees safety in addition to ensuring battery life.
In terms of batteries, LYRIQ adopts 811 high-nickel and low-cobalt ternary lithium batteries, and further optimizes the battery cell formula, achieving a thermal stability increase of about 10% in the cell, even under extreme external temperature conditions in winter, it can still maintain the stability, safety and endurance of the internal temperature.
Secondly, looking at the battery module, LYRIQ's battery cells are equipped with an insulating wall made of aerospace-grade new generation of aerogel insulation materials, with a thermal insulation temperature of up to 600 °C and a thermal conductivity of less than 0.024, which can effectively avoid the occurrence of thermal diffusion. Even if there is a real thermal runaway event, the gas generated by the thermal runaway of the battery can be quickly discharged from the active exhaust channel, bringing thermal management technology guarantee from the inside out.
In addition, LYRIQ also has the blessing of two intelligent technologies: BEV HEAT Efficient Integrated Thermal Management System and wBMS Wireless Battery Management System. BEV HEAT system takes into account the advantages of air source heat pump and water source heat pump, can integrate air conditioning, battery and electric drive three major heat systems for vehicle heat management, driving process, the system can also dynamically collect vehicle batteries, motors and other systems generated in the waste heat, into air conditioning heat source into the cabin, thereby reducing the overall energy consumption of the vehicle, improve the endurance.
Thanks to the BEV HEAT system, the air outlet temperature of the LYRIQ air conditioner can reach 45°C in just 2 minutes at -10°C. Compared with the traditional PTC heating method, the BEV HEAT system makes the heating speed of the cockpit and the battery cell faster, and can also greatly reduce the energy consumption during winter heating, reduce the low temperature endurance attenuation, and ensure battery life.
The wBMS wireless battery management system uses wireless communication technology to divide the complex battery system into a brain and a number of intelligent nodes, and the intelligent nodes are arranged in the middle of each battery module to view the battery's power, heat, failure, etc. at any time, so that the management of the battery system becomes more accurate and real-time.
In addition, Cadillac LYRIQ has also undergone extreme tests across China, North America, New Zealand and other places, including many of the extreme cold conditions of -40 °C, and has carried out comprehensive tests and verifications for the dynamic performance, comfort and performance of the vehicle, so that consumers can use it with peace of mind and guarantee.
LYRIQ battery testing is in the true chapter
As mentioned above, Cadillac LYRIQ is based on the pure electric platform of Aoteneng, and is known for its reliable safety and advanced technology. So is this Aoteneng battery on the LYRIQ able to withstand the test?
In the LYRIQ battery limit test, engineers hang the battery to a height of 2m (national standard 1m), and then let the battery pack fall freely through the free landing. The result is obvious, during the whole test, there is no electrolyte leakage, no fire and explosion, and in the test environment that is strictly 2 times the national standard, it still maintains good battery safety and stability.
In the anti-extrusion test, the Aoteneng battery pack applied on LYRIQ withstood the weight extrusion equivalent to 30 tons, reaching the national standard 3 times the standard. In the face of test conditions higher than the national standard, it was still possible to achieve no fire, no explosion and no serious deformation for 10 minutes.
Relying on the real-time intelligent monitoring system, nano-scale aviation material aerogel, safety valve and exhaust channel patent design, anti-arc design, integrated fully independent liquid cooling system, aerogel fire blanket seven-fold protection, LYRIQ equipped with Aoteneng battery pack in the face of test experiments far beyond the national standard, still perform with ease, enough to see Cadillac in the safety of the absolute attention, as well as industry-leading safety assurance.
As the pioneering work of cadillac brand intelligent pure electric transformation, LYRIQ's ingenuity in battery safety and outstanding performance in extremely cold environments confirm Cadillac's pursuit of luxury quality, which is safe enough, reliable enough and trustworthy.
Relying on the advantages of Aoteneng pure electric platform, Cadillac LYRIQ redefines the new benchmark of luxury new energy vehicles when solving the pain points of the majority of users, and completely opens the curtain of the era of Cadillac electrification.
