In southern China, it is unthinkable that city buses do not have air-conditioning. But if the air conditioner is turned on from the morning to the night, its cruising range will usually drop by more than 30%, and some will reach 50%.
At present, the electrification of buses is accelerating, and the pressure to increase the specific energy of power batteries is very large. At the same time, a brand-new subject has been proposed for bus air-conditioning manufacturers. It is the author who took these questions tohttps://syouzikiya.jp/ share with colleagues the experience after learning from the engineers and technicians of electric bus air-conditioning manufacturers.
- The insufficiency of air-conditioning in fuel vehicles
As the “big energy consumer” of the automobile assembly, the air conditioner of fuel vehicles accounts for 20% of the engine power. The development of the automobile industry and consumption upgrades have made people increasingly demanding air conditioners. Therefore, the basic trend of engine configuration for fuel passenger cars is high-power and diesel. In the context of increasingly stringent fuel limits, how to reduce the power consumption of bus air-conditioning systems and make fuel vehicles more economical will be a huge challenge. It is not suitable for the development requirements of electric vehicles if only simple electrification of the traditional fuel vehicle air conditioner is carried out.
The evolution from engine cars to electric cars is an inevitable trend. There is no engine on the electric bus, and the air-conditioning power comes from the steering on-board battery. In fact, the specific energy of the current power battery is far from the basic requirements of the car’s cruising range. Under this premise, automotive electric air conditioners must be highly efficient and low energy consumption. In other words, the level of automotive electric air-conditioning is also one of the bottlenecks in the development of electric vehicles, and the redevelopment of new products is a must.
