1. The rapid urbanization in China in the past ten years has led to the transformation of a large area of rural areas into cities or towns, and people's daily travel range has become larger, and the demand for cars has become stronger. Most elderly people are too old to get a driver's license and drive a car, which forms a huge market demand that normal cars cannot cover.

2. In recent years, the rapid industrialization of electric bicycles and tricycles has led to a decrease in the cost of lead-acid batteries. Although the old scooter looks more like a car, it is not essentially different from the electric bicycle in technical difficulty. Perhaps it can be said that the old scooter is an electric tricycle with a shell.

First of all, let's analyze pure electric vehicles. As the name implies, pure electric vehicles only use batteries as energy sources and use motors to drive them. Its advantages are energy saving, environmental protection and low cost of car maintenance. At present, some cities do not need a driver's license or a car inspection. The disadvantage is short battery life. At present, the battery life of pure electric vehicles in the world is generally about 200 kilometers, and the battery loss will increase with the extension of service time, and the cost of replacing the battery in the later stage is not small.

Hybrid electric vehicles are dual-powered, and can use both engines and motors. Its advantages are energy saving, environmental protection and low oil consumption. The disadvantage is that the price is relatively high and the cost of replacing the battery in the later stage is high.

There are many manufacturers of pure electric vehicles in China, such as Chery, BYD, Changan, SAIC and so on. Tesla is imported, the price is relatively high, but the battery life is the best.

Domestic BYD, hybrid car, did a good job. Joint venture Toyota, Honda, Cadillac and so on.

Depending on personal needs, if you don't need to run long distances or have a car at home, you can consider pure electric vehicles. If it is a rigid demand, you can consider a hybrid car or a conventional car.

If it is a hybrid car, the way to refuel can be to refuel the gasoline engine or to charge the electric engine. In daily life, there is also a way to choose. However, the service time of the rechargeable engine is short, so if you run a long distance, you'd better choose a gasoline engine.
