How Many Kilometers Can One Kilowatt-Hour Drive?
2 Answers
1 kilowatt-hour can generally drive between 5 to 8 kilometers. Below is an introduction to automotive batteries: Battery Cost: In pure electric vehicles, besides providing the power source, the battery also supplies energy for systems like electric air conditioning, electric brakes, and electric steering—collectively known as the three small electric systems. In terms of cost, the battery currently accounts for 30%-40% of the total vehicle cost, making it the highest proportion among the three major electric systems (battery, electric control, motor). In comparison, the engine in traditional energy vehicles accounts for about 15% of the total vehicle cost. Overall, the battery is a key factor determining the range, price, and driving quality of electric vehicles, each of which significantly influences consumer purchase decisions. Battery Capacity: Generally, household car batteries have a capacity between 54-60Ah. The battery capacity indicates the amount of electricity the battery can discharge under certain conditions (discharge rate, temperature, termination voltage, etc.). The capacity unit for car batteries is usually Ah. For example, a 60Ah battery can discharge continuously for 60 hours if the discharge current is 1A.
I've been driving an electric car for three years and found there's no standard answer to this issue. My car's official claim is 10 kilometers per kWh, but in reality, with air conditioning on in summer, it only does 7 kilometers, and in winter it's even worse, maybe just 6 kilometers. On highways, the wind resistance is high and power consumption is fast, while in city traffic jams, it's actually more energy-efficient. My friend drives a Xpeng P7, which is lighter than my car, and he can get 12 kilometers per kWh. To save power, you need to master the 'golden right foot' technique—avoid sudden acceleration and hard braking, try to use energy recovery mode, and don't let tire pressure get too low. Battery condition is also crucial; as the battery ages and its capacity decreases, the range will drop.
