What are the categories of new energy vehicles? What to do if the range of new energy vehicles is low in winter

New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source and integrate advanced technologies in vehicle power control and driving. New energy vehicle power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and supercapacitors, among which lead-acid batteries and supercapacitors mostly appear in the form of auxiliary power sources.

New Energy Vehicle Classification

New energy vehicles are classified into fuel cell electric vehicles (FCEV), hybrid electric vehicles, hydrogen-powered vehicles, pure electric vehicles (BEV, solar vehicles), and other new energy vehicles (such as high-efficiency energy storage devices, dimethyl ether). New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source (using new on-board power devices) and integrate advanced technologies in vehicle power control and drive. New energy vehicle power sources mainly include lithium-ion batteries, nickel-hydrogen batteries, fuel cells, lead-acid batteries, and supercapacitors, among which lead-acid batteries and supercapacitors mostly appear in the form of auxiliary power sources.

What to do if new energy vehicles have low range in winter

It is normal for pure electric vehicles to have a low range in winter, and there is no good way to solve this problem. What car owners can do is to calculate their range to prevent running out of power on the road.

Most pure electric vehicles use lithium batteries. Common lithium batteries in pure electric vehicles include ternary lithium batteries and lithium iron phosphate batteries.

The low temperature performance of ternary lithium batteries is better than that of lithium iron phosphate batteries.

The positive electrode of the ternary lithium battery is made of ternary materials. Some ternary lithium batteries' positive electrodes are made of nickel, cobalt, and manganese, while some ternary lithium batteries' positive electrodes are made of nickel, cobalt, and aluminum.

The temperature is relatively low in winter, and the conductivity of the electrolyte in the lithium battery will deteriorate, which will cause the battery performance to decline. The decline in battery performance will affect the range of pure electric vehicles.

If you want to prevent the performance of lithium batteries from deteriorating in winter, the best way is to heat the lithium batteries and keep them within the appropriate operating temperature range.

However, most car manufacturers do not yet have lithium battery heating technology.

However, in the future, automobile manufacturers will definitely develop lithium battery heating technology, which can prevent the performance of lithium batteries from deteriorating when the temperature is too low in winter.

In fact, you can use the cooling system of the battery pack to heat the lithium battery. The coolant in the cooling system can heat up the lithium battery, which can improve the performance of the lithium battery in winter.
