Marvel X was first known for its 0The 29cd's excellent drag performance is impressive, which is one of the best in its class. Then there is its original intelligent heat pump air conditioning technology, which not only provides more energy-efficient cooling in hot weather, but also cleverly solves the problem of "battery life for warmth" for electric vehicles.
As we all know, in addition to high-speed driving, air conditioning heating is one of the biggest factors in the power consumption of electric vehicles. Marvel X's technology reduces energy consumption by more than half compared to PTC in environments above -5, bringing users a more comfortable driving experience.
In terms of power core, the advantages of the Marvel X are more obvious. First of all, let's talk about the battery temperature control system: extreme fluctuations in temperature will affect the performance of lithium batteries, thereby affecting the charging, discharging (acceleration), battery life and other performance of electric vehicles. To make matters worse, a temperature deviation from the ideal range can also jeopardize the reliability and safety of the battery.
Therefore, it is especially important to let the battery work at a "comfortable" temperature.
The battery temperature control system should consider not only the ambient temperature, but also the heat generated by the chemical reaction of battery charging and discharging, as well as the heat generated when an electric current passes through it. At present, the battery temperature control system on the market is mainly divided into two forms: water circulation (water cooling) and air cooling, each with its own advantages and disadvantages. Air cooling uses air as a heat transfer medium, which is simple in structure, light in weight, and has no risk of liquid leakage, but the temperature control effect may not be good in extremely cold or hot environments. Liquid cooling uses liquid as the heat exchange medium, which has higher heat exchange efficiency per unit time and is more suitable for extremely cold or hot areas, but there is a risk of leakage, the structure is relatively complex, and the power consumption is also large.
Experiments show that under the premise of controlling other variables, the common ambient temperature of air cooling and liquid cooling effects are similar, and air cooling can meet the normal use requirements. Different models need to choose the appropriate thermal management method according to their own battery pack structure and applicable scenarios.
The Marvel X opted for a battery pack in an air-cooled form with a total of 96 modules and a battery capacity of around 52kWh.
Rather than blindly increasing battery capacity, Marvel X focuses more on optimizing the BMS battery management system to make the battery output more efficient. This strategy allows the Marvel X to provide users with a more stable and reliable driving experience while maintaining range.
