Main features of electric vehicles
Pure electric vehicles , relative to fuel vehicles, the main difference (different) lies in four major components, drive motors, speed controllers, power batteries, and car chargers. It is powered by a public ultra-fast charging station relative to the gas station. The difference in quality of pure electric vehicles depends on the four components, and the value of the four components depends on the quality of the four components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components. The speed of a pure electric vehicle is fast and slow, and the starting speed depends on the power and performance of the driving motor. The length of its continuous mileage depends on the size of the vehicle's power battery. The weight of the vehicle's power battery depends on which power battery is used, such as lead acid and zinc. Carbon, lithium batteries, etc., their volume, specific gravity, specific power, specific energy, cycle life are all different. This depends on the manufacturer's positioning and use of the vehicle grade as well as market definition and market segmentation. The drive motor of pure electric vehicles currently has DC brush, brushless, permanent magnet, electromagnetic, and AC stepper motor. Their selection is also related to vehicle configuration, use and grade. In addition, the speed control of the drive motor is also divided into step-level speed regulation and stepless speed regulation. There are electronic speed controllers and speed controllers. The motor has a hub motor, an inner rotor motor, a single motor drive, a multi-motor drive, and a combined motor drive. The selection and preparation of the motor and speed controller also have an impact on the grade and price of the vehicle. The public ultra-fast charging station is the infrastructure for the commercialization of pure electric vehicles. It can be perfected in order to make the former smooth and worry-free. On the contrary, it is its short legs, subject to its constraints and influence, the commercial practice of electric steam in Europe and the United States. This is fully explained. We recognize this, but we are not doing enough. In addition, the cable connector problem between the charger and the car battery must be standardized, forming the same as the battery type, voltage binning, speed (power size) elements, otherwise pure electric vehicles and public ultra-fast charging stations can not effectively dock, this industry At present, a piece of white paper is waiting for us to develop, but it must be planned, designed and implemented, so as to avoid futile efforts to avoid costly work. The four major components of pure electric vehicles and large chargers for public charging stations, special cables, cable connectors and even billing and charging systems. This is a new component in the automotive industry. Nothing will be no shortage of rice, no position, no Perfect is the short leg is restricted by it. At the same time, the related parts manufacturers should form an industrial chain and develop together. The State Administration of Political Affairs and Administration's "New Energy Vehicle Announcement Management Measures and Implementation Rules" was implemented on November 1, 2007. "General technical conditions for urban and rural agricultural (special) electric vehicles" are also in the process of brewing. The commercialization of pure electric vehicles has begun to take shape in rural areas, and we should not turn a blind eye. In the future, pure electric vehicles that meet international and market requirements must comply with the following items: 1. Electric vehicle R&D, manufacturing operations must comply with relevant national laws and regulations. The performance of the whole vehicle and parts must meet the national technical standards and specific requirements. 2. Electric vehicles are powered by electricity and driven by electric motors. They no longer produce new pollution and no longer cause flammable or explosive hazards. 3. The battery used for electric vehicle energy storage must be non-polluting and environmentally friendly. It has a durable life and features ultra-fast charging (currents above 2-3C). The vehicle determines the mileage of the primary charge according to the purpose, so as to use the battery pack with sufficient power to make full use of the ultra-fast charging of the public charging station to extend the mileage. 4. The motor unit should have high efficiency energy conversion. The direct utilization and recovery of the energy of braking and deceleration, and strive to achieve high efficiency of comprehensive energy utilization of vehicles. 5. Set the maximum speed according to the vehicle use and driving occasions, and must not exceed the limit value of traffic regulations to reasonably select the power of the motor and configure the battery pack capacity. 6. Vehicle driving operation, simple and effective control, reliable work, and ensure driving safety. 7, mechanical and electrical devices are durable and less maintenance. The cost of vehicle operation is low. 8. Based on the target market demand, provide practical and suitable models to meet the needs, and strive to achieve comprehensive integration of technology, economy, practicality and function. In the future, industrialization and commercialization of electric vehicles that are popular among users must meet the following characteristics: accurate positioning, proper use, suitable driving area, and best performance. The right model and economical configuration. Reliable performance, convenient handling. Environmentally friendly battery, durable life, enough power, ultra-fast charging, perfect network, and in place service. Low cost and minimal maintenance.
