How many kilowatt-hours are needed to fully charge a car?
2 Answers
Car full charge requires charging degree needs to be determined according to the power of the car battery, different car battery power also has differences, generally ordinary car charging for one hour requires 0.22 kilowatt-hours, 48v20a battery full charge requires 1.5 kilowatt-hours, 72v20a battery full charge requires about 2.3 kilowatt-hours. The following is a related introduction about car batteries: 1. Overview: The battery is an essential part of a car, which can be divided into traditional lead-acid batteries and maintenance-free batteries. 2. Structure: The structure of the car battery is mainly composed of positive (negative) plates, separators, electrolyte, tank shell, connecting strips and pole piles.
I've been driving electric vehicles for several years, trying everything from domestic XPeng to Tesla. The actual electricity required for a full charge mainly depends on the battery capacity. For example, the XPeng G3 has only a 50 kWh battery, but with about 10% charging loss, the actual grid electricity might be around 55 kWh. Larger cars like the Tesla Model Y come with a 78 kWh battery, and a full charge often requires over 85 kWh because DC fast charging is more efficient. From my personal experience, electricity consumption is slightly higher in cold winters and a bit more economical in summers. Generally, mid-sized vehicles range between 50 to 70 kWh, but it's best to check the vehicle manual for specifics—don't just rely on advertising claims, and consider daily usage losses. I recommend checking charging efficiency monthly to avoid battery aging issues. In short, there's no fixed number for charging your car; you'll need to try it a few times to feel comfortable.
