What does a range of 150km mean?
3 Answers
A range of 150km refers to the driving distance an electric vehicle can travel on a fully charged battery before needing to recharge, specifically up to 150 kilometers. The following factors affect the range of an electric vehicle: 1. Charging equipment: Similar to household appliances, the quality of charging equipment can influence the energy replenishment and output of the EV battery, thereby affecting the range. 2. Tire pressure: Just like with gasoline-powered cars, low tire pressure increases rolling resistance and lateral steering resistance, leading to faster battery consumption and reduced range. 3. Overloading: Similarly to gasoline vehicles, overloading an electric vehicle increases its weight, requiring more battery output and accelerating power consumption, which inevitably decreases the range.
The car manufacturer claims a range of 150km, which means the vehicle can travel up to 150 kilometers on a full tank of fuel or a full charge under official testing conditions. However, in real-world driving, you'll never actually achieve that number. Take my electric car for example—it's rated for 300 kilometers, but with the air conditioning on in summer, carrying three passengers on the highway, the range drops by 20% instantly. The colder the weather, the worse the range gets. In sub-zero temperatures, the battery drains alarmingly fast, and if you drive aggressively with sudden acceleration and braking, the range shrinks even further. So, if you're buying a car with a 150km range, it's best suited for city commuting. My neighbor drives 30 kilometers daily for work, and getting five days out of a single charge is already a great deal.
The figure of 150km range may seem straightforward, but there's more to it. There are several testing standards - Europe uses WLTP, Japan adopts JC08, while China employs CLTC, resulting in up to 20% variance in test data. Turn on the AC, and the range immediately drops a notch; steering wheel and seat heating consume even more power. My tests show that using the heater in winter at 0°C increases energy consumption by 30%. A fully loaded car with luggage and underinflated tires will silently eat into your range. Seasoned drivers recommend applying at least a 20-30% discount to the advertised range for practical use, which proves more reliable.
