Basic structural components of new energy vehicle charging system: The vehicle charging system circuit consists of power supply circuit, starting circuit, ignition circuit, lighting and signal device circuit, instrument information system circuit, auxiliary device circuit, and electronic control system circuit. 1. The power supply circuit, also known as the charging circuit, is composed of the battery, generator, regulator, and charging indicator device. Power distribution and circuit protection devices can also be included in this circuit. 2. The starting circuit is composed of the starter, starting relay, starting switch, and starting protection circuit. Devices for preheating during low-temperature starting and their control circuits can also be included in this circuit. 3. The ignition circuit is unique to gasoline engine vehicles. It consists of the ignition coil, distributor, electronic ignition controller, spark plug, and ignition switch. Electronically controlled ignition systems are generally included in the engine electronic control system. 4. The lighting and signal device circuit is composed of headlights, fog lights, position lights, turn signals, brake lights, reverse lights, interior lights, and related control relays and switches. 5. The instrument information system circuit consists of instruments and their sensors, various warning indicators, and controllers. 6. The auxiliary device circuit is composed of various electrical devices designed to improve vehicle safety and comfort. The types of auxiliary electrical devices vary depending on the vehicle model, with higher-end models featuring more comprehensive auxiliary electrical devices. These generally include windshield wipers and washers, defrosting (anti-fog) devices, air conditioning systems, audio systems, etc. More advanced models may also include power windows, electronic door locks, power seat adjustment, and electric remote-controlled mirrors. Electronically controlled airbags are included in the electronic control system. 7. The electronic control system mainly includes the engine control system (including fuel injection, ignition, emission control, etc.), automatic transmission and cruise control system, anti-lock braking system, airbag control system, and other circuits.
The basic structure of a new energy vehicle's charging system is quite crucial, and I think it includes several core components. The charging port serves as the entry point, responsible for connecting the external power source to the vehicle, with common types including fast-charging and slow-charging plugs. Next is the onboard charger, which converts alternating current (AC) to direct current (DC), making it suitable for charging high-voltage batteries. Then there's the battery management system, which monitors the battery's status in real-time, such as voltage, temperature, and capacity, to prevent overheating or over-discharge. External equipment like charging piles provides the power source and is categorized into home and public types. Wiring and control units connect all components in series, with control signals transmitted through the communication system to ensure stable and safe current flow. I've seen some vehicles equipped with additional cooling devices to assist with heat dissipation, which is especially important during fast charging. For safety, fuses and insulation layers are essential to prevent short-circuit incidents. The entire design aims to efficiently transmit energy, protect battery lifespan, and extend the vehicle's usage time.
I still remember when I first got into new energy vehicles, learning about the charging system left a deep impression. It basically starts with the charging gun, which you plug into the vehicle's port to connect to an external power source. The vehicle has a built-in charging controller responsible for managing the input current, handling different types of electricity through a converter. The battery system is the core, consisting of the main battery and monitoring software to ensure balanced charging and discharging—once, my car charged slowly due to an issue here. External charging stations come in various forms; I often use a home wallbox, where power rating affects charging speed. Cables and connectors need regular inspection to prevent aging and leakage. During charging, safety features like circuit breakers activate automatically—if overheating occurs, charging stops, and I've noticed fast charging relies more on these mechanisms. Overall, while the structure is complex, it's maintainable, and simple maintenance can extend the system's lifespan.
