The power for the air conditioning system is mainly from the PV panels. If the power from the PV panels is not enough, the battery will supply the power to the air conditioning system. In order to have the sufficient power for the system, the project design four research topics for the air conditioning system of the electric bus. 1. Using and optimizing the variable-frequency technique to reduce power consumption of the compressor in the air conditioning system. 2. Reducing the body temperature by applying the cooling technique to the seats in electric bus, so that the default temperature of the air conditioning system can be higher and then the power consumption can be lower. 3. Developing the techniques for recharging the main battery system using the surplus power of the solar air conditioning system, including the switching control technique and the system integration of EV battery management system with the DC/DC converter. Thereby, the economic benefits of solar air conditioning system can be maximized and the single-charge drive range of the EV can be increased while the operation and safety of the system are not affected. 4. Using the nMPPO technique to have the maximum power of the PV panels and intelligently adjust power distribution of the system, leading to lower power consumption. Therefore, in the first year, the key techniques will be developed and the models of simulation will be built. Then, all sub-systems will be integrated, tested and modified. In the second year, the solar air conditioning system will be integrated into the electric bus and then tested, modified and verified.電動巴士太陽能空調系統nMPPO變頻技術局部致冷electric bussolar air conditioning systemnMPPOvariable-frequencycooling
