What Does Comprehensive Range Mean?

Electric vehicles have two range values, one called the comprehensive range and the other called the constant-speed range (also known as the maximum range). These two range values are derived from different testing conditions. The comprehensive range is tested under conditions that more closely resemble everyday driving environments. Factors affecting the range of an electric vehicle: 1. Charging equipment: The quality of the charging equipment will affect the energy replenishment and output of the electric vehicle's battery, thereby impacting the range. 2. Tire pressure: Similar to gasoline-powered cars, low tire pressure increases rolling resistance and lateral steering resistance, causing the vehicle's battery to deplete quickly and reducing the range. 3. Overloading: Just like with gasoline-powered cars, overloading an electric vehicle undoubtedly increases its weight, requiring more battery output and accelerating energy consumption, inevitably leading to a reduced range. It is recommended to follow the law and avoid overloading. 4. Sudden stops and starts: Sudden stops or starts mean activating the motor in a very short time and consuming more electrical energy, which can also shorten the motor's lifespan. It is recommended that after starting an electric vehicle, it should be driven at a steady, slow speed for a distance before accelerating. Electric vehicles also need a warm-up period. While driving, maintaining a steady speed helps keep the battery in a stable working state, ensuring optimal range.
As someone who frequently commutes in an electric vehicle, the comprehensive range is the metric I care about most—it represents approximately how many kilometers you can drive on a full charge. This number typically refers to the total driving distance under standard testing conditions, averaging both congested urban roads and highway cruising. In real-world use, there can be fluctuations; for example, cold winters or hot summers may reduce the range slightly. Before buying a car, I carefully review the official data because it helps me manage my budget and plan my commute. For instance, my car has a claimed range of 400 kilometers, but with daily air conditioning use, it might drop to around 350. When choosing a car, a higher range is indeed more practical, but it also comes at a higher price. Remember, maintaining a steady speed can extend the actual mileage—avoid aggressive acceleration and braking.
I've studied numerous automotive technical parameters. The comprehensive range refers to the theoretical maximum distance a vehicle can travel on a single charge or tank of fuel, derived by combining various driving scenarios. Testing standards like WLTP simulate real-world conditions, accounting for gradient changes and traffic influences. The core factors are battery capacity or fuel tank size, plus the efficiency of energy recovery systems. In actual usage, vehicle weight, ambient temperature, and passenger count can slightly reduce the range. From an engineer's perspective, choosing models with high-energy-density batteries ensures better trip planning, though manufacturers' claims may be slightly optimistic. Consumers should select vehicles based on their commuting habits to minimize unnecessary energy waste and develop smooth driving techniques to approach the official range figures.
