What is the charging voltage of an electric vehicle?

There are many types of electric vehicles, including small electric vehicles, medium-sized buses, and large buses. The battery voltages used in these different types of vehicles vary. Small cars generally use around 350V, medium-sized buses use 400-500V, and large buses use around 600V. Electric vehicles refer to vehicles powered by an on-board power source. The working principle of an electric vehicle is: battery - current - power regulator - motor - power - transmission system - driving the vehicle. Electric vehicles are categorized into pure electric vehicles, hybrid vehicles, and fuel cell vehicles. Pure electric vehicles are driven solely by electricity. The range of an electric vehicle depends on the capacity of its on-board battery. Generally, the range of a pure electric vehicle is around 300 kilometers. Charging methods are divided into fast charging and slow charging, with fast charging taking about 1 hour and slow charging taking about 6-7 hours. The production technology of electric vehicles is relatively simpler, as they can be charged anywhere with a power supply. Hybrid vehicles use both electricity and fuel for driving, and the two modes can be switched freely. When the vehicle's battery level drops below 10%, the vehicle will switch to fuel power. In other words, hybrid vehicles can use either the engine or the motor as the power source independently. Fuel cell vehicles use fuel cells as the power source. The fuel undergoes a chemical reaction to provide power to the vehicle, improving the combustion efficiency of the engine.
When it comes to the charging voltage of electric vehicles, I think it depends on how you charge. If you use a standard household outlet, it's around 120 volts, common in North America; if you have a dedicated home charging station (Wallbox), you can use 240 volts. When you go to public fast-charging stations, the voltage is higher, possibly 400 volts DC, sometimes as high as 800 volts in newer models. The voltage level directly affects charging time: a 120-volt outlet takes all night to fully charge, 240 volts gets it done in a few hours, and fast charging at 400 volts or above reaches 80% in about 30 minutes. When driving an EV, I've noticed that the voltage must match the vehicle's specifications—my older car, for example, can only handle up to 240 volts, and forcing it to fast-charge could damage the battery. There are big differences between countries: European households use 230 volts, while North America uses 120 volts, so you need to check local standards when choosing a charger. The new trend is 800-volt systems in cars like Porsche or Hyundai, which are more efficient and energy-saving, but safety always comes first—never attempt to wire things improperly yourself.
