汽车充电系统的发展历程、现状及未来趋势

Development History,Current Situation and Future Trend of Automobile Charging System

传统汽车上普遍具有两个电源,一个是蓄电池,另一个是发电机。蓄电池的主要作用是汽车起动时,向起动机、点火系统、电控单元等供电;或者在发电机不发电、发动机不工作时供电。而发电机基本承担着汽车行驶过程中所有用电设备的供电,同时对蓄电池充电,始终保持蓄电池的电量处于富足的状态,以便下一次起动用。蓄电池和发电机共同组成为汽车充电系统,为汽车的所有工作状态提供了可靠的电源保证。随着时代的发展,充电系统的组成和工作原理方案,从早期的机械触点式电压调节发展到了现代的智能电源管理系统。本文将从汽车充电系的组成及原理角度简要阐述其发展历程和现状,并总结其未来发展趋势。

Traditional cars generally have two power sources,one is a battery and the other is a generator.The main function of the battery is to supply power to the starter,ignition system,electronic control unit,etc.when the car is started;or to supply power when the generator does not generate electricity and the engine does not work.The generator is basically responsible for the power supply of all electrical equipment during the driving of the car,and at the same time it charges the battery,always keeping the battery power in a state of abundance for the next start.The battery and the generator together form a car charging system,which provides a reliable power supply guarantee for all working states of the car.With the development of the times,the composition and working principle scheme of the charging system have developed from the early mechanical contact voltage regulation to the modern intelligent power management system.This article will briefly explain its development process and current situation from the perspective of the composition and principle of the car charging system,and summarize its future development trends.
