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 types of vehicles are different. 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 divided into pure electric vehicles, hybrid vehicles, and fuel cell vehicles. Pure electric vehicles use pure electric drive. The range of an electric vehicle depends on the capacity of the 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. Fast charging takes about 1 hour, while slow charging takes about 6-7 hours. The production technology of electric vehicles is relatively simple, as they can be charged wherever there is a power supply. Hybrid vehicles use both pure electric and fuel drive, and the two modes can be switched at will. When the car's battery level is below 10%, the car will use fuel drive. In other words, hybrid vehicles can use either the engine or the motor as the power source. Fuel cell vehicles use fuel cells as the power source. The fuel undergoes a chemical reaction to provide power to the vehicle, improving the engine's combustion efficiency. The range of an electric vehicle depends on the capacity of the on-board battery.

I remember the charging voltage for electric vehicles varies quite a bit, mainly depending on the charging method. For the slow home charging I use, just plugging into a regular socket, the voltage is around 220 volts AC. I plug it in every night to charge overnight—it's economical and convenient when fully charged, but you have to be careful not to overload the home circuit, otherwise unstable voltage might mean charging for hours without much gain in battery level. Public fast charging stations are more powerful, with DC voltage soaring to 400 volts, and up to 800 volts at peak. I tried it once and got 200 kilometers of range in just ten minutes—perfect for emergencies during long trips, though the equipment is pricier, so it's best to stick with reliable brands like Tesla's Superchargers. Temperature also affects voltage performance: battery efficiency drops in the cold winter, while summer heat might trigger overheating protection and slow charging down. These details make me realize how important it is to choose the right voltage level when charging.
