Electric Vehicles are vehicles that use the vehicle's power supply as the power source to drive the wheels with the motor and meet the requirements of road traffic and safety regulations. There are three key core technologies for electric vehicles: one is the power battery, the other is the motor, and the third is the control system. Among them, the power battery is the most critical, and its performance indicators and economic costs determine the commercialization process of electric vehicles. The main performance of power battery research and development products is at the international advanced level, and the battery industry has a solid foundation, but some weak links need to be solved.
The components of Electric Vehicles include: electric drive and control systems, mechanical systems such as drive transmissions, and work devices for completing tasks. The electric drive and control system is the core of electric vehicles and the biggest difference from the internal combustion engine. The electric drive and control system consists of a speed control device that drives the motor, the power supply, and the motor. Other devices for electric vehicles are basically the same as those for internal combustion engines.
