What does minimum charge state fuel consumption mean?

Minimum charge state fuel consumption refers to the fuel consumption of a plug-in hybrid electric vehicle in its minimum charge state. Introduction to hybrid electric vehicles: Broadly speaking, a hybrid electric vehicle refers to a vehicle whose propulsion system consists of two or more individual propulsion systems that can operate simultaneously. The vehicle's driving power is provided by one or more of these systems depending on the actual driving conditions. Commonly referred to as hybrid vehicles, they generally mean oil-electric hybrid vehicles, which use traditional internal combustion engines (diesel or gasoline engines) and electric motors as power sources. Some engines may be modified to use alternative fuels such as compressed natural gas, propane, and ethanol. Classification of hybrid electric vehicles: Based on the connection method of hybrid propulsion, hybrid electric vehicles are generally divided into three categories. The first is the series hybrid electric vehicle (SHEV), whose power system mainly consists of an engine, a generator, and a drive motor connected in series. The second is the parallel hybrid electric vehicle (PHEV), where both the engine and the drive motor are power units, and the power of these two units can be output together or separately. The third is the power-split hybrid electric vehicle (PSHEV), which combines the structures of series and parallel hybrids. It mainly consists of an engine, an electric generator, and a drive motor.
I've been driving a hybrid car for several years. Simply put, the fuel consumption at minimum charge state refers to the car's fuel performance when the battery is nearly depleted. For example, in my car, when the battery level drops very low, the engine runs at full capacity, and the fuel consumption per 100 kilometers can be significantly higher than usual. Why is this important? Because it reflects the vehicle's true fuel efficiency when the battery can't sustain the load. While it's manageable during city driving, on long trips or in traffic jams, you're more likely to encounter this state. Higher fuel consumption in this scenario not only means more frequent refueling but can also put extra load on the engine. To manage it better, I've tried maintaining steady acceleration, using cruise control more often, not setting the air conditioning too low, and avoiding sudden braking—these small habits really help save on fuel costs. Actually, checking the battery status on the navigation system each time I drive has become a daily routine, helping me adjust my driving accordingly.
