How many kilowatt-hours are needed for a 500-kilometer range?
2 Answers
Assuming an electric vehicle voltage of 60V, this translates to 600Wh, meaning a full charge requires 0.6 kilowatt-hours. Below is relevant information about electric vehicles: Components: The electric drive and control system, mechanical systems such as the drivetrain, and work devices to accomplish set tasks. The electric drive and control system is the core of an electric vehicle and the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of the drive motor, power source, and motor speed control device, among others. The setup of electric vehicles is largely similar to that of internal combustion engine vehicles. Power source: Provides electrical energy to the drive motor of the electric vehicle, which converts the electrical energy into mechanical energy. The most widely used power source is lead-acid batteries, but with advancements in electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan.
How much electricity is needed for a 500 km range? It depends on the vehicle. Let me talk about common electric cars. Small electric sedans have lower energy consumption. Popular compact models consume around 14-16 kWh per 100 km, which translates to about 70-80 kWh for 500 km. However, larger SUVs with greater weight and wind resistance may consume up to 20 kWh per 100 km, requiring around 100 kWh for 500 km. Driving habits also matter—rapid acceleration and using air conditioning can increase consumption, potentially exceeding theoretical values. For used cars, battery degradation reduces range, so don't just rely on advertised specs for new cars—test them. Charging costs are also worth considering. At a few cents per kWh, driving 500 km costs just tens of yuan, much cheaper than gasoline cars.
