1. Different concepts
1) New energy vehicles: refers to the technical principles formed by using unconventional vehicle fuels as power sources (or using conventional vehicle fuels and adopting new vehicle power devices) and integrating advanced technologies in vehicle power control and driving. Advanced cars with new technologies and new structures.
2) Pure electric vehicle: refers to a vehicle that is powered by a vehicle power supply and uses a motor to drive the wheels, and meets the requirements of road traffic and safety regulations.
2. Different advantages and disadvantages
1) New energy vehicles: The advantages are low fuel consumption and less pollution, which solve the problems encountered by pure electric vehicles such as energy-consuming air conditioning, heating, defrosting, etc. The entire vehicle can work at the same time due to multiple power sources, and the power of the entire vehicle The performance is excellent; the disadvantage is that the system structure is relatively complex; the fuel-saving effect of long-distance high-speed driving is not obvious.
2) Pure electric vehicles: The advantage is that the technology is relatively simple and mature, and it can be charged wherever there is a power supply; the disadvantage is that the energy stored per unit weight of the battery is too little, and because the batteries of electric vehicles are more expensive and do not form economies of scale, they The purchase price is relatively expensive; as for the cost of use, some trial results are more expensive than cars, and some results are only 1/7 to 1/3 of cars. This mainly depends on the life of the battery and local oil and electricity prices.
