To reduce air pollution and avoid petroleum exhaustion problem, many advanced countries, especially Japan installed Hybrid Vehicles (HV). As the use of HV popularizes around the world, there will be a huge amount of End-of-Life HV in the near future, and the proper treatment of these End-of-Life HVs, especially the waste NiMH (Nickel-Metal Hydride) batteries, will become a serious problem. Currently, the recycling of NiMH battery is gaining substantial attention. However, instead of recycling waste NiMH batteries directly, regenerating and reusing a used NiMH battery for a secondhand HV will largely reduce waste battery generation and demand for new NiMH battery. However, the environmental impact of regenerating and reusing a waste NiMH battery was not clear and has not been compared with the situation when using a brand-new NiMH battery. The purpose of this research is to compare the environmental performance (CO2 emission) of regenerated NiMH battery and brand-new NiMH battery in an HV from their production to usage stage and to discuss the validity of using a regenerated NiMH in Japan and in other countries using the Life-Cycle Assessment (LCA) approach. This research analyzed the composition of a NiMH battery and the CO2 emission during the manufacture, transportation, regeneration and usage process of a NiMH battery. The data used in this research was collected from reports and data published by the government of Japan, vehicle makers and previous studies. Original field survey and interview research on battery regeneration operators were also performed. The result showed that there is not a big difference in environmental effect. Moreover, by doing so, a huge amount of resource will be saved from battery manufacturing process while reducing waste generation. It is recommended that waste NiMH battery should be regenerated and reused in HV instead of being recycled directly in the future.

Resource Circulation

In recent years, Next-Generation Vehicles, especially Hybrid Vehicles (HV) are increasing rapidly in advanced countries. In fact, not only advanced countries but also some developing countries also own a large quantity of HV by importing secondhand HV from advanced countries. For instance, Mongolia is importing a huge amount of secondhand HV from Japan every year. On the other hand, there will be a huge amount of waste HV in Mongolia that needs to be recycled properly soon, and yet, this problem has been neglected and the number of waste HVs in Mongolia is still unknown. The purpose of this research is to propose a method to predict the End-of-Life HV number in Mongolia. This research finds that the Japanese vehicle deregistration rate can represent vehicles’ durability and can be used to estimate End-of-Life HV number in Mongolia. The result shows that there will be a huge amount of End-of-Life HV as well as Nickel-Metal Hydride (NiMH) batteries generated in Mongolia from now on, even more than in Japan, which is the largest HV market. It is urgent for the Mongolian government to build a proper End-of-Life HV recycling system now, and international cooperation on resource circulation is also expected.

And Performance

The use of electric vehicles (EVs) is viewed as an attractive solution to reduce CO2 emissions and fuel consumption resulted from transport sector, but the EVs implementation is limited to driving distance and and the charging process that inconvenience. The analysis of energy consumption characteristics of Nickel-Metal Hydride (NiMH) battery that commonly used as the energy source for EVs become an important foundation to study the durability and performance of the battery when applied in addition to increase the driving range from this EVs. This research aims to test the durability and the performance of the Eneloop type of Nickel-Metal Hydride (NiMH) battery that used for the racing car competed on ENE1-GP Japan at Suzuka Circuit Japan. From this experiment will be achieve the energy consumption estimation systematically, based on this data the parameters can be decided accurately for the EVs that attend the competition. The battery will be test under room temperature and the load given during the test from 0.1A to 10A. The average temperature during the performance test were observed using thermal camera. The best result from this experiment is on 5A, the battery will effectively use and can fit the requirement to complete the race in 18 minutes and 49 seconds for 3 cycles (laps). On the other hand, this data also can become the foundation to develop the electric vehicle which has similar specification.
