Does a hybrid car use fuel or electricity when running the air conditioner?

Hybrid cars use fuel when running the air conditioner. Concept of hybrid cars: Refers to vehicles equipped with more than one power source: batteries, fuel cells, solar cells, or generator sets of internal combustion engines. Currently, hybrid vehicles generally refer to those with an internal combustion engine generator plus a battery. Advantages of hybrid cars: With hybrid power, the maximum power of the internal combustion engine can be determined based on the average required power, operating under optimal conditions of low fuel consumption and reduced pollution. When higher power is needed and the internal combustion engine is insufficient, the battery supplements it. When the load is low, the surplus power can generate electricity to charge the battery. Since the internal combustion engine can operate continuously and the battery can be constantly charged, its range is the same as that of a conventional car.
Hybrid vehicles primarily use electricity to power the air conditioning, but they may indirectly consume some fuel as well. For example, after driving a Toyota hybrid for many years, I’ve observed that the AC compressor is electrically driven and powered directly by the battery. If the battery is sufficiently charged—such as right after being fully charged or when driving in pure electric mode—the AC runs entirely on electricity. However, when the battery level drops to a certain point, the engine automatically starts to generate electricity to keep the AC running. In this case, fuel is actually being used to produce electricity for power. So, while the AC is fundamentally electric-driven, the energy source behind it may involve fuel. This helps with fuel efficiency because, unlike traditional vehicles where the engine directly drives the compressor, the hybrid system improves efficiency. Running the AC does consume slightly more fuel compared to not using it, but the difference is smaller. I recommend keeping an eye on the battery charge indicator and maximizing electric usage by running the AC when the battery level is high.
