This paper is an evaluation study of electric loads of a production type of HEV (Hybrid Electric Vehicle) under a commuting monitor in Beijing. The monitor was implemented with a half year between hot and cold season by Japanese resident staff drove the vehicle mostly from house to the office. The commuting monitor analysis is done with the data to the same route and the same driver. The observation study of the commuting monitor reveals the following technical findings. Motor re-generation energy gradually decreases from hot season to cold season. Mahalanobis distance analysis could be found out the cause of the electric energy decrease when air conditioner unloaded. The high level of the air conditioner load affects the vehicle input (throttle openings). Although the re-generation load changes along with the environment temperature, the motor-assisted input load tends to steady states. That means the engine is supplied almost steady power from the motor irrespective with environment temperature. Battery keeps control the temperatures refer to environment temperature level. The hybrid air conditioner system worked efficiently which revealed with the difference of load levels between a travel mode and an idling stop mode. There is no notable running difference between an idling mode and the idling stop mode both in summer and in winter.
