What are the three electric components covered by the warranty of new energy vehicles?
1 Answers
For new energy vehicles, the three electric components covered by the warranty refer to the motor, power battery, and electronic control system. From the 30,000 yuan Wuling Hongguang MINIEV to the 7 million yuan Rimac pure electric sports car, all rely on these three electric systems. It can be said that the three electric components are the core parts of new energy vehicles. Below is a detailed introduction: Drive Motor: The motor is the power source of new energy vehicles. Based on structure and principle, motors can be divided into three types: DC drive, permanent magnet synchronous, and AC induction, each with different characteristics. Power Battery: The power battery is the energy source for the drive motor. Current power batteries are mainly distinguished by their cathode and anode materials, including lithium cobalt oxide, ternary lithium, lithium manganese oxide, and lithium iron phosphate. Ternary lithium and lithium iron phosphate batteries are more commonly used in new energy vehicles. Electronic Control System: The electronic control system is actually a general term, which can be further divided into the vehicle control system, motor control system, and battery management system. A major feature of new energy vehicles is the very close interconnection between various electronic control systems. Some vehicles even use a single electronic control system to manage all electrical equipment on the car, so it's appropriate to refer to them collectively.
