Electric vehicles are environmentally friendly, more suitable for urban roads, and the shape of the car is not limited by the constraints of the engine and its accessories. The cost of driving is only 1/3 of the traditional car. However, electric vehicles still have many shortcomings, which make it impossible to spread rapidly. For more than 100 years, the biggest bottleneck restricting the development of electric vehicles is the battery, and this fact has not changed today. Compared with the traditional fuel tank, the latter is installed. 1 kilogram of gasoline can store 12 kWh of energy, while a 1 kilogram of lithium-ion battery can only store up to 0.2 kWh of energy. In other words, a lithium-ion battery that stores the equivalent of a normal car fuel tank (40 kg) will weigh 2 to 3 tons! Even considering the higher efficiency of the motor, it takes about 700 kilograms of lithium-ion battery to make the electric car have the same driving range as a normal car, which in turn will greatly reduce the performance of the electric car. So all current electric vehicle batteries are unlikely to provide really enough energy. At the same time, the city-type electric car with nearly half a ton of lithium-ion battery can only reach a top speed of about 120 kilometers, and the electric vehicle battery is inconvenient to charge and the charging time is long. The lithium ion battery accounts for nearly half of the expensive price of the car. The purchase and use of the car. Rail transit is an electric vehicle that does not need to carry a large-capacity battery, but it must have a conductive track connected between the car and the road, which will limit the road of the car, making the car lose its flexibility.
