As we all know, a lot of pure electric vehicles due to the impact of low temperatures, the activity of three yuan lithium battery pack will decrease in the winter, so the mileage performance of the vehicle will be a significant decline, thus affecting the car driver’s experience and convenience sex. Therefore, many car prices winter life force to resolve anxiety, in my opinion, pure electric vehicles to break through the arctic area.
The most commonly used way is cheqi PTC heating system. PTC heating system before the vehicle is started, first with the heating wire to a heated three yuan lithium battery group, so that the power of the battery pack reaches the correct operating temperature. But the work of the energy of the system comes from three yuan lithium battery pack, and therefore power consumption.
Some car companies also employed a diesel heating system, for example, car Weimaraner. The heating system is set to increase diesel small diesel generators in electric vehicles, the system can use the heat from the heating battery diesel engine emitted. However, this system will bring a certain amount of exhaust emissions, it is not very environmentally friendly.
Finally, I believe that pure electric vehicles arctic want to break the restricted area, one of the most effective way is a breakthrough in the study of solid-state battery pack. Solid-state power because the working temperature of the battery pack to adapt to a wider range, higher energy density, can provide longer mileage performance, more reliable.
