Abstract

The demand for batteries is expected to rise in line with the growing need for electric vehicles. As the number of electric vehicles increases, more battery waste will be generated, considering the average battery lifespan is only 10 to 15 years. If batteries are not recycled, this will lead to a significant accumulation of waste. Therefore, it is important to evaluate the ease of battery disassembly. This assessment can help manufacturers design batteries that are easier to disassemble. This study aims to determine the disassembly ease score and provide improvement recommendations using the Ease of Disassembly approach through eDiM and Difficulty Rating. The disassembly process is analyzed using the Ease of Disassembly Metric (eDiM) to evaluate difficulty levels based on standard disassembly operation time, and Difficulty Rating based on the indicators of Accessibility, Positioning, and Force. Based on the analysis results, the most difficult disassembly operations involve removing screws from the top cover, bottom cover, controller circuit, and BMS circuit, as well as detaching the nickel strip. The research findings indicate the presence of disassembly stages with low time values but high preference-based difficulty levels.

Abstract

Limitations and the absence of electricity will disrupt the continuity of people activities. This is because electricity is one of the needs of the people and is felt to be very important. The availability of electricity, which is supported by power plants sourced from fossil fuels, certainly burdens the lower middle class community, including the fishing community. The solution that can be implemented to reduce the burden and dependence of the community on fossil fuels as a source of electrical energy is the use of solar energy. Indonesia has good potential when using solar energy as an alternative energy for power generation. This is because Indonesia is a tropical country that has abundant solar energy potential. Thus, this abundant solar resource is expected to meet household-scale electricity needs in remote areas that have not been reached by the State Electricity Company (PLN). PLTS in this service is carried out to meet electricity needs independently in residential homes that will be used day and night. The type of residential house used is a simple house type, with a total daily electrical power requirement of 1.314Wh and added 20% so that the total need is 1,576.8 Wh.
